Underfloor Diffusers

PATENTED HVAC FLOOR AIR DIFFUSER VAV TECHNOLOGY

Choose from directionally adjustable, manually adjustable volume or variable volume (VAV) operation in square, round, linear or rectangular configurations. Note that these features can be combined. Our most popular diffusers are VAV with directional and volume adjustment.

Our floor diffusers are available in a variety of colors, sizes, materials and airflow capacities to meet your project design needs. CV diffusers may include a basic galvanized steel catch pan or a larger acoustical boot, and our most popular selection is an aluminum VAV diffuser with manual airflow adjustability. Lower cost polycarbonate diffusers are available.

Our VAV diffusers use the AirFixture globally patented Time Modulation VAV technology which intelligently controls air delivery based on the temperature demand of the occupied space.

These units incorporate a direct drive air valve that automatically adjusts individual terminals using Time Modulation logic to maintain the thermostat set point, making it the longest-lasting, zero maintenance VAV air valve in the world.
