Name: Cassette fans
Availability: InStock

Low-profile ceiling cassette extract fans with an integral grille face, backdraught shutter and a spigot for flexible or rigid duct connection, built on small forward-curved direct drive wheels — the class Twin City covers with Model DDF at 6" to 10.5" wheel diameters, airflow to 2,100 CFM and static pressure to 1.75" w.g. Depth is held to what a standard ceiling void will accept.

Fitted in bathrooms, small toilets, pantries and single offices in residential, hotel and commercial fit-outs. They combine the extract point and the fan in one accessory, which suits refurbishments where running a duct back to a central riser would mean opening the whole ceiling — but the low static capability means the duct run behind them has to be short and genuinely as drawn.
