Let customers speak for us
3D Printed Y-Piece Splitter for LUNOS Nexxt
Made to Order
• Our 3D printed products are made to order.
• Please allow 1 to 2 days for manufacturing before shipment.
• Please call us if your order is urgent.
Our 3D printed Y-piece splitter is custom-designed to perfectly fit the intake/exhaust duct of the LUNOS Nexxt decentralised ERV system. Printed in-house with a professional 3D printer from UV stable acrylonitrile styrene acrylate (ASA) or V0 fire-rated polycarbonate (PC), it offers exceptional strength, temperature resistance, and safety for continuous use in residential and commercial ventilation systems.
This precision-printed fitting allows you to neatly connect two 125mm ducts to the LUNOS Nexxt system — perfect for installations where the external wall isn’t located immediately behind the Nexxt unit.
To ensure optimal performance:
- Always use insulated ducting to minimise condensation and heat loss.
- Pull ducts tight and trim to exact length before securing.
- Ensure there is a slight fall on ducts to allow any condensation to drain to outside.
- Support all ductwork with appropriate hanging straps to prevent sagging or kinks.
- Proper installation will help reduce pressure build-up and maintain balanced system operation.
Each splitter is printed with a Bambu Lab H2D Pro and undergoes fit testing to guarantee a snug, leak-free connection — designed and made in Australia to support quality LUNOS Nexxt installations.
