DVS Home Ventilation Systems

Invest in Your Family’s Health with a DVS Home Ventilation System

Fresh Ventilation are proud to bring DVS home ventilation systems to the Australian market. With more than three decades of experience, DVS have built a reputation for class-leading innovation and technologically advanced systems that make homes healthier, drier, and more comfortable to live in.

The Heart of a Healthy Home

Dusting, vacuuming, and regular cleaning all help a home feel healthy, but one critical element is often overlooked — ventilation. Ventilation sits at the very heart of a healthy home, quietly working in the background to manage moisture, improve air quality, and support your family’s wellbeing.

DVS home ventilation systems are designed to gently and continuously introduce fresh, dry, filtered air into the living areas of your home, either from the roof space or directly from outside. By doing so, they help dilute and remove stale, moisture-laden air that can otherwise lead to condensation, mould, and poor indoor air quality.

Within the DVS range are both positive pressure ventilation systems, which create a slight positive pressure inside the home to push out stale air, and balanced pressure heat or energy recovery ventilation systems (HRV/ERV), which supply fresh air while simultaneously extracting stale air from wet areas such as kitchens and bathrooms. In heat recovery systems, warmth from the outgoing air is transferred to the incoming fresh air via a high-efficiency European counterflow heat exchanger, improving comfort and energy efficiency.

All DVS home ventilation systems use advanced technologies such as high-efficiency EC motors and intelligent controls to operate quietly, efficiently, and responsively. By reducing excess moisture, they significantly help prevent issues such as condensation on windows, mould, and mildew — common triggers for asthma and allergies. In winter, when homes are sealed up and heating is in use, a DVS system plays a vital role in maintaining healthy air circulation and removing damp, moisture-filled air.

Once installed, a DVS ventilation system costs from as little as eight cents per day to run, making it a smart investment not only in your family’s health but also in the long-term condition and value of your home.

DVS EC Premium Connect

Positive Pressure Home Ventilation System

The DVS EC Premium Connect is a premium positive pressure home ventilation system, designed to keep your home dry, healthy, and comfortable with minimal user input. It represents the very latest ventilation technology from DVS, giving you fingertip control over humidity, temperature, and indoor air quality.

By gently introducing fresh, filtered air into your living spaces, the system creates a slight positive pressure inside the home. This positive pressure continuously pushes out stale, moisture-laden air, replacing it with drier, cleaner air from your roof space or directly from outside — helping protect both your family’s health and your home itself.

Designed for a Healthier, Drier Home

The DVS EC Premium Connect is specifically engineered to manage the key contributors to poor indoor air quality: moisture, carbon dioxide (CO₂), and stale air. Everyday activities such as breathing, cooking, and showering release large amounts of moisture into the home. Left unmanaged, this can lead to condensation, mould, and discomfort.

Using intelligent sensing and automatic control, the DVS EC Premium Connect continuously adapts its operation to ensure that only air which improves the health of your home is introduced.

How the System Works

At the core of the system is a high-quality German-made EC fan motor by ebm-papst, delivering quiet, energy-efficient, and reliable performance. The system draws drier, fresher air from the roof space or from outside the home and passes it through a high-efficiency air filter, tested to international standards.

The filtered air is then gently supplied into the home via DVS patented ceiling diffusers, designed specifically for even air distribution. The air is directed along the ceiling, where it mixes naturally with warmer air and spreads evenly throughout the living areas. In simple terms: fresh air in, stale air out.

Intelligent Sensing and Automatic Control

Humidity Sensing

The system continuously monitors humidity levels both inside the home and in the incoming air supply. It automatically adjusts operation to ensure ventilation only occurs when it will actively make the home drier and healthier.

CO₂ Sensing

Closed windows can trap carbon dioxide and other contaminants, leading to fatigue, poor sleep, and reduced concentration. The DVS EC Premium Connect includes a wireless CO₂ sensor that constantly measures indoor CO₂ levels. When levels rise above healthy thresholds, the system automatically increases fresh air delivery.

Up to four wireless CO₂ sensors can be positioned throughout the home for targeted monitoring.

Temperature Sensing

The system compares the temperature of the supply air with the air inside your home. When warmer air is available, the system makes use of that free warmth. When the supply air is cooler — such as during winter evenings — the fan speed can be reduced to maintain comfort while still providing background ventilation. The responsiveness of the system can be adjusted to suit your personal preferences.

Simple, Intuitive Control

The DVS EC Premium Connect features a large, easy-to-read touchscreen controller, allowing you to see exactly what your system is doing at a glance. Each system is professionally configured and calibrated to suit the size and layout of your home, operating automatically day-to-day.

If you wish, you can:

  • Fine-tune airflow rates
  • Adjust control settings
  • Activate Fan Boost to quickly clear excess moisture or odours

The controller is Wi-Fi enabled, allowing automatic software updates whenever DVS release improvements — without the need for costly service visits.

Optional Add-Ons

Automatic Summer Ventilation Add-On

During summer, roof spaces can become extremely hot. This add-on allows the system to automatically switch from roof-space air to fresh, filtered outside air when roof temperatures rise too high.

The system continuously measures temperatures inside the home, in the roof space, and at the external intake. Based on your chosen settings, it intelligently selects the best air source — helping keep your home fresher when you’re not home to open windows, while also filtering pollen and airborne irritants.

DVS Automatic Summer Ventilation Addon

Integrated Heat Transfer Add-On

The Integrated Heat Transfer Add-On allows you to make better use of heat you’ve already paid for. Warm air from a room with a strong heat source — such as a living room with a wood heater — can be transferred to cooler rooms like bedrooms and hallways.

This provides supplementary heating to spaces isolated from the main heat source, potentially reducing reliance on additional in-room heating. The system can switch manually or automatically between ventilation mode and heat transfer mode, delivering fresh air when required and redistributing warmth when needed.

DVS EC Reclaim Connect

Balanced Pressure Home Ventilation System with Heat Recovery

The DVS EC Reclaim Connect is DVS’s ultimate whole-house balanced pressure home ventilation system, purpose-designed for modern, airtight homes. As Australian building standards move towards tighter envelopes, controlled mechanical ventilation with heat recovery becomes essential. The DVS EC Reclaim Connect delivers precisely that — build tight, ventilate right.

Designed and manufactured by DVS, the system continuously extracts stale, moisture-laden air while supplying fresh, filtered outdoor air at equal rates. Heat energy contained in the extracted air is reclaimed and transferred to the incoming fresh air, dramatically reducing heat loss and improving overall energy efficiency. Homes become easier to heat and cool, and existing air-conditioning systems can operate more effectively.

Designed for Airtight, Energy-Efficient Homes

Mechanical ventilation is essential for managing moisture and indoor air quality in airtight buildings. The DVS EC Reclaim Connect provides controlled ventilation while maintaining thermal efficiency, making it ideal for modern homes, high-performance builds, and renovations aiming for improved airtightness.

By recovering energy that would otherwise be exhausted outside, the system reduces heating demand, lowers running costs, and minimises environmental impact — without compromising fresh air supply.

How the System Works

Heat recovery works by transferring warmth from the outgoing stale air to the incoming fresh air using a highly efficient counterflow heat exchanger, without the two air streams ever mixing. As warm air is extracted from the home, its heat energy passes through the heat exchanger core and is absorbed by the cooler incoming outdoor air, which is then delivered to the living spaces pre-warmed.

While the Recair Sensitive heat exchanger core used in the DVS EC Reclaim Connect is rated at up to 98% efficiency under controlled laboratory conditions, real-world performance is typically lower. In practical installations — particularly where the unit is located in a cold roof cavity — overall heat recovery efficiency is more realistically around 82%, which still represents a substantial reduction in heat loss and energy demand compared to ventilating without heat recovery.

The DVS EC Reclaim Connect is typically installed in the roof space (or within a cupboard if allowed for during construction) and uses two German-made, high-efficiency EC fans ⑥. One fan quietly and continuously extracts damp, stale air from the home ①. As this air passes through the system, the heat exchanger recovers energy from it — energy generated by everyday activities such as cooking, showering, and paid-for heating — before the air is exhausted outside.

At the same time, the second fan draws a constant supply of fresh, filtered outdoor air into the system ③. The recovered energy is transferred to this incoming air, gently warming or cooling it before it is supplied to the home ②. A state-of-the-art European counterflow heat exchanger enables this process to operate at up to 98% efficiency, while keeping the stale and fresh air streams completely separate ④.

By re-using energy that would otherwise be lost, the system significantly reduces the amount of heating required to maintain a comfortable indoor temperature. This translates to lower energy consumption, reduced running costs, and a smaller environmental footprint.

When warm air is available in the roof space, the DVS EC Reclaim Connect — when fitted with the optional Solar Gain Roof Intake — can capture this free heat without supplying roof-space air directly into the home ⑤. This is achieved by opening the roof-space bypass, allowing roof-space air to mix with the extracted exhaust air and pass through the heat exchanger, helping to pre-warm the incoming fresh air.

To further improve performance in warmer months, an Automatic Summer Bypass can be fitted. This allows incoming fresh air to bypass the heat exchanger when the outside air is cooler than the indoor air, preventing unnecessary warming and improving summer comfort.

Intelligent Sensing and Automatic Control

Humidity Sensing

The system continuously monitors humidity levels inside the home and in the incoming air supply. Ventilation automatically adjusts to ensure only air that will help keep the home drier and healthier is introduced.

CO₂ Sensing

A wireless CO₂ sensor continually monitors carbon dioxide levels. When CO₂ rises above healthy levels, the system instantly increases ventilation rates — supporting better sleep, concentration, and overall wellbeing.

Up to four wireless CO₂ sensors can be positioned throughout the home.

Temperature Management

Recovered energy is reused within the home, reducing heating demand. Intelligent temperature monitoring allows the system to adapt operation to seasonal conditions.

Simple, Intuitive Control

The DVS EC Reclaim Connect features a large, easy-to-read touchscreen controller, allowing you to see exactly what your system is doing at a glance. Each system is professionally configured and calibrated to suit the size and layout of your home, operating automatically day-to-day.

If you wish, you can:

  • Fine-tune airflow rates
  • Adjust control settings
  • Activate Fan Boost to quickly clear excess moisture or odours

The controller is Wi-Fi enabled, allowing automatic software updates whenever DVS release improvements — without the need for costly service visits.

Optional Add-Ons

Automatic Summer Bypass Add-On

During warmer months, the Automatic Summer Bypass allows incoming fresh air to bypass the heat exchanger when outside air is cooler than indoor air. This prevents unnecessary warming of supply air and improves summer comfort. The bypass can operate automatically or manually, based on system settings and temperature sensors.

DVS Automatic Summer Ventilation Addon

Solar Gain Roof Intake Add-On

When warm air is available in the roof space, the Solar Gain Roof Intake allows this free heat to be utilised. Roof-space air is mixed with extracted air and passed through the heat exchanger to help pre-warm incoming fresh air — without supplying roof-space air directly into the home.

DVS Air Filters — Clean Air, Naturally

DVS air filters are installed with every DVS EC Premium Connect and DVS EC Reclaim Connect system. They are essential to the long life, efficiency, and performance of your ventilation system, and are manufactured to meet international air filter standards.

Natural Clean-Air Technology

DVS filters use patented Helix™ filtration technology, made with New Zealand wool, to actively clean the air. Unlike conventional filters that rely solely on dense media, Helix fibres use natural electrostatic properties to attract and capture even very fine particles and airborne pollutants — delivering cleaner air for you and your home with lower resistance to airflow.

This technology is scientifically developed by Lanaco in New Zealand using locally grown wool, and is trusted globally — so much so that Helix technology has been selected by NASA for critical life-support filtration in future lunar missions.

The Best of New Zealand Innovation

By combining advanced science with sustainable materials, DVS Helix filters deliver class-leading indoor air quality with a significantly lower environmental impact — proving that high performance and responsible design can go hand in hand.

Designed for Performance, Sustainability, and Ease of Use

DVS have always designed their filters to be easy DIY replacements, using a practical filter pocket design. Progressing to Helix technology has allowed DVS to retain this simple design while significantly increasing filtration performance — a win for customers and the environment.

Helix filters are:

  • Extremely breathable, with very low airflow resistance
  • Energy efficient, reducing fan workload and running costs
  • Bacteria resistant, as wool fibres naturally inhibit microbial growth
  • Effective at reducing toxins, with wool fibres binding harmful vapours
  • Safer against fire, thanks to the natural flame-retardant properties of wool
  • Eco-friendly and sustainable, using biodegradable natural fibres

DVS Standard Helix Wool Filter

The Standard Helix Wool Filter is DVS’ latest-generation filter and the default option supplied with DVS systems.

  • MERV 15 rated for high-efficiency particle capture
  • >99% efficient at 2.5 microns
  • Uses natural wool fibres — the world’s most positively charged fibre — to attract and trap fine dust and contaminants
  • Class-leading filtration without restricting airflow, allowing the fan to operate efficiently and cost-effectively
  • Lower environmental footprint than synthetic filter media

The result is world-class filtration performance while maintaining excellent airflow and low energy use.

DVS Hybrid Helix Carbon Filter

If you live in an area affected by persistent odours — such as traffic, industry, agriculture, or bushfire smoke — the Hybrid Helix Carbon Filter is the ideal upgrade.

  • Combines Helix wool filtration with activated carbon
  • Excellent at reducing odours and gaseous pollutants before air enters the home
  • Often referred to as the “smell stopper”
  • Suitable for use with all DVS home ventilation systems
  • Made using New Zealand wool, maintaining the same sustainability benefits

Choosing the Right DVS Home Ventilation System

Selecting the right home ventilation system is not about choosing the “best” product in isolation — it’s about choosing the right solution for your home. Australian housing stock varies enormously in age, construction quality, airtightness, and layout, and ventilation systems must be matched accordingly to work effectively.

The right solution depends on several key factors:

  • How airtight the home is
    Leakier homes benefit from systems that work with natural air leakage, while tighter homes can take advantage of more controlled ventilation strategies.
  • Whether moisture or air quality is the primary concern
    Some homes struggle mainly with condensation and dampness, while others experience stuffy air, high CO₂, or persistent odours.
  • Roof space access and layout
    The availability, size, and condition of the roof space (or subfloor) directly influence which systems can be installed and how ducting can be run.
  • Budget and installation constraints
    Retrofit practicality, installation complexity, and cost all play a role in determining the most suitable system.

Which System Is Right for My Home?

As a general guide:

Positive pressure home ventilation systems are ideal for:

  • Older or leakier homes
  • Homes with a dry, breathable roof space
  • Properties experiencing condensation, mould, or damp smells
  • Homeowners seeking a simple, cost-effective retrofit solution

Positive pressure systems work with the natural leakage of the building, gently flushing out stale air and moisture while introducing fresh, filtered air.

Balanced pressure home ventilation systems are better suited to:

  • Homes seeking greater control over air supply and exhaust
  • Properties where maintaining more neutral pressure is desirable
  • Homes built to an above-average standard, but not fully airtight
  • Situations where heat recovery is beneficial for comfort and efficiency

Balanced pressure systems use a HRV or ERV core to recover energy from outgoing air, providing continuous fresh air with reduced heat loss — without the construction requirements of high-performance systems.

No One-Size-Fits-All Solution

There is no universal ventilation system that works best in every home. The most effective results come from matching the system to the building, rather than forcing a particular technology into an unsuitable environment.

For this reason, every home ventilation system we supply is carefully selected and configured to suit the specific home, its construction type, its moisture and air quality challenges, and the needs of its occupants. This tailored approach ensures reliable performance, long-term effectiveness, and a healthier indoor environment.
