Filter Cassettes for Circular Duct
FILC-C

Filter cassettes manufactured from 0.7mm galvanised mild steel. Includes sealed circular spigots either end, removable access door, and 50mm grade 4 pleated panel filter (cassettes for 100mm thick filters can also be supplied on request).

Although we are able to provide filter cassettes of any dimension, the sizes listed below are limited to the more common single panel filter sizes.

Use the drop down menus below to select overall size and spigot size (spigot size must be smaller than overall box size).

Lastly, use the 'access' drop down to specify the access door location. This is not applicable to square shaped sizes.

By default the filter cassettes are manufactured with a length of 250mm. This is to allow room for the air to disipate and use a greater surface area of the filter. Should you require a shorter length due to space restrictions it is possible to stipulate a custom length in the "Any other info" text box below.

If you require a filter cassette with a circular spigot one end and some other connection on the other end, please either use the text box below or send us a drawing.
