Ergovent Kvadro 100 - 100MM (4" Inch) | White Square Frameless Diffuser

The Ergovent Kvadro 100 is a 100MM square frameless ceiling diffuser designed to disappear into plasterboard ceilings and walls while still delivering reliable airflow. The pure gypsum, paintable face can be finished with the same coating as the ceiling, giving architects, builders and tradies a truly minimalist ceiling vent that suits modern Australian interiors.

With a 100MM round frame pipe and 240MM x 240MM body, it connects easily to standard rigid or flexible ductwork or plenum boxes on supply or exhaust branches. A built in balancing damper with PU segments lets installers fine tune airflow on site, supporting up to 92 M3/H per diffuser without visible regulators. The anti static gypsum body and optimised outlet profile help reduce dirt rings around the grille and support quieter operation.

Ideal for residential and light commercial projects, this flush mounted gypsum ceiling diffuser is a smart upgrade for new builds, renovations and ventilation maintenance work across Australia.
