Ventilation Floor Diffuser - Products
Ventilation floor diffusers, also called floor registers, cover floor duct openings and direct conditioned air into the room, usually with an adjustable damper to control or shut off flow. Moonshine Bath stocks floor diffusers in common duct sizes and finishes built to withstand foot traffic.
An adjustable diffuser lets you balance airflow room by room. Every ventilation floor diffuser ships free across the USA, Canada and Mexico, dispatches within 24 hours on weekday orders before 2 PM EST, and is covered by our price match plus 10 percent beat guarantee.
Frequently Asked Questions
How do I size a floor diffuser?
Measure the duct opening (the hole in the floor), not the old register's outer edge. Floor diffusers are listed by duct size, such as 4 by 10 or 4 by 12 inches, with a larger faceplate that overlaps the opening.
Can I close a floor diffuser to redirect air?
Most floor diffusers have an adjustable damper lever to open, close or partially restrict airflow, which helps balance temperatures between rooms. Avoid closing too many at once, which can strain the system.
Are floor diffusers strong enough to walk on?
Floor registers are built sturdier than wall or ceiling grilles to handle foot traffic. For high-traffic areas, choose a heavy-gauge metal diffuser for the most durability.
