Explore sturdy HVAC air diffusers, grilles, and registers at F.W. Webb. A toe space grille is a vent cover that removes air from an indoor space and returns it to an HVAC system for recirculation; a register is a vent cover that adjusts to direct airflow; a floor or ceiling diffuser distributes airflow in a set pattern at an optimal level. Use our helpful filters to sort the grilles and registers by size, material, deflection, actuation type, and fin spacing. Browse top-quality HVAC air diffusers, grilles, and registers from trusted makers Hart & Cooley and Rectorseal to find the right fit for an existing unit.
The difference between HVAC air grilles and diffusers is that a grille lets air move vertically without deflection, while a diffuser lets you direct the air to different angles.
