Budget vs Premium Sub Floor Ventilation Kits

Our budget sub floor ventilation kits are designed to be price comparable with other, more basic sub floor ventilation kits available online. Unlike cheaper kits available elsewhere, our budget kits use the same premium components as our premium kits, which are components we install in our business on a daily basis. Our budget kits include fewer items, making them directly comparable to other kits available online.

Our budget sub floor ventilation kits cannot be installed in the same way that we would install our professional sub floor ventilation systems. They do not include enough components or extraction points to achieve the same coverage. They are a simple solution for providing air flow to a sub floor area only. If you would like a kit that replicates our professional installation service, please see our Premium Sub Floor Ventilation Kits that also include custom installation maps and one-on-one technical advice.

Included Items

• 1 x 150mm AC Centrifugal Fan (made in Germany).
• 1 x 6m V-Flex Duct (made in Australia).
• 2 x 150mm Plastic Louvre Grilles.
• 1 x Digital Timer (battery backup).
• 1 x 30m Duct Tape.
• 1 x 50m Hanging Tape.
• 5 Years Warranty.
• Installation Photos and Videos.

What Makes Fresh Ventilation Different

Fresh Ventilation is a family owned and operated business. Our main business has specialised in the installation of premium quality ventilation systems for over 10 years. Our sub floor ventilation kits use the same premium components we install in our business on a daily basis.

Effective sub floor ventilation requires quality components and proper installation. Given that no two sub floor areas are the same, there is no one-size-fits-all solution to sub floor ventilation. This is why we place a strong emphasis on customised solutions and after-sales support to help you with installing your system.

Our focus is on premium products and expert advice to create ventilation systems that actually work.

Why Premium Components and Proper Installation Matter

Fresh Ventilation supplies a range of efficient and technologically superior sub floor ventilation products. Our exclusive design is based on years of knowledge, experience and trialling competing products.

Not all components are equal!

System Design

• Instead of using a single larger fan, we use smaller fans but more of them.
• More fans allow greater coverage, better efficiency and more extraction points.
• A single larger fan makes more noise, uses more power and requires longer duct runs to cover the same area as two smaller fans. This is inefficient and leads to uneven duct lengths and subsequently uneven air flow.
• Our smaller fans use the same size ducting as our exhaust grilles and we allow one exhaust grille per fan. This allows air to be freely exhausted without a reduction in air flow due to pressure buildup.
• Larger fans need reducers to reduce the duct size so that they can be connected to exhaust grilles. This results in a reduction of air flow due to resistance.

Fans

• Our 150mm AC motor centrifugal fan has a capacity of 560 m³/h.
• The single speed AC motor consumes 52 W.
• Our fans make less noise and use less power. Some larger fans use 193 W when operating and have less capacity than two of our smaller fans.
• Our fans have a 5 year replacement warranty.

Duct

• Our duct is manufactured in Australia from two layers of high grade metallised polyester bonded together with fire rated resin encapsulating spring steel wire.
• Our duct is not prone to tearing or unravelling like single layer competing products.

Timer

• Our digital timer has a battery backup. It won't lose time and start running in the middle of the night.
• Our digital timer can be programmed differently on different days of the week. This is ideal when you want different operation on the weekends.

Why Sub Floor Ventilation is Important

Many pest and building inspectors recommend sub floor ventilation to reduce termite risk.  These systems are very effective in homes that experience a continuing musty odour or where there is mould on shoes and clothes in wardrobes or on furniture in living spaces.

Your sub floor area may seem insignificant because it does not form part of your living room. However, the fact of the matter is that this space actually has a high impact on the quality of air you breathe in while you are indoors and may affect your health. Poorly ventilated sub floor areas are often damp. This dampness can result in mould, mildew, musty odours, wood rot and pest infestation in your sub floor area and can also contribute to the spread of mould, mildew and allergies above. 

Sub floor ventilation can remove ground moisture from underneath raised floors, creating a drier and warmer sub floor area.

AC Motors

AC motors are cheaper than EC motors but still provide excellent performance. They are very quiet during operation and move large volumes of air through ducting. They operate at one fixed speed where they are most efficient.

Our AC motor centrifugal fans have the following qualities:

• Single speed
• Approximately 560 m³/h air flow and 52 W power usage
• Very low noise during operation
• R2E190 motor manufactured by ebm-papst in Germany
• Custom Australian made fan housing
• 5 year warranty
• IP 44 protection rating.

Normal Profile Fans vs Low Profile Fans

Normal Profile is our standard fan configuration. Normal Profile fans are round with a diameter of 342mm. Normal Profile fans are recommended for most installations.

Low Profile fans are available for shallow installations where access is limited. Low Profile fans are oval with a width of 340mm and a height of 217mm. The smaller footprint means that air flow is reduced by about 10%, but they still provide exceptional performance as their shallow environments generally have less cubic volume to ventilate.
