Door Relief

Door Relief
Shop door relief grilles for ducted air conditioning installations at FastFlex, Melbourne's trade HVAC wholesaler. Door relief grilles allow conditioned air to transfer freely between rooms when internal doors are closed, preventing pressure imbalances that can cause ducted systems to work harder, increase noise, and reduce airflow efficiency. They are a standard requirement in zoned ducted installations where rooms are sealed off from the main return air path. This range features natural anodised aluminium door relief grilles in a wide selection of sizes from 300x160mm through to 600x600mm, suitable for installation into standard interior doors and partition panels. The natural anodised finish provides a durable, corrosion-resistant surface that suits most residential and light commercial interiors across Victoria. Available at wholesale trade pricing with same-day dispatch from our Thomastown warehouse. Trade account holders get access to live online pricing. Call us on 03 9464 5400 or order online today.
