Make-Up Air Supply Ventilator Sydney

Every cubic metre of air exhausted from your building needs to be replaced. Without a proper make-up air system, powerful exhaust fans create negative pressure that pulls in unfiltered outside air through every gap and opening. This brings in dust, pollen, and unconditioned air that strains your HVAC system, creates uncomfortable drafts, and compromises indoor air quality. In commercial kitchens, insufficient make-up air can even cause dangerous backdrafting of combustion appliances.

We supply and install make-up air supply ventilators across Sydney that replace exhausted air with fresh, filtered, and conditioned outside air at a controlled rate. Our systems can include heating, cooling, and filtration to ensure the incoming air is at the right temperature and quality for your space. Whether it’s for a commercial kitchen, an industrial facility, or any space with high exhaust rates, we design solutions that maintain proper building pressure, improve HVAC efficiency, and ensure a comfortable, safe indoor environment that meets AS 1668.2 standards.
