Filter Cassettes for Rectangular Duct
FILC-R

Filter cassettes manufactured from 0.7mm galvanised mild steel. Includes 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, including filter banks for larger ducts (large enough to hold several filters), the sizes listed below are limited to the more common single panel filter sizes.

Use the drop down menu below to select size. Connections A and B refer to either end of the filter cassette. It's common - although by no means compulsory - to use a Doby frame at either end to enable a simple bolt in to a duct run.

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

All filter cassettes are 250mm in length unless requested otherwise.
