Envelope Filter


Features

Modular sizing

The size 50 - 1100 range of envelope filters is designed to cater for the most common dust problems, which usually involve a ducted system. Larger systems utilize a number of units in a modular form, or other types of filters.


Filter media

The filtration of the air is achieved by passing it through cloth arranged in a multi-pocket, envelope form. Standard units are supplied with bags manufactured in cotton fabric, however, other media are available for greater efficiency. These include plain needle felt fabrics, felts with either surface treatments or membranes, or alternatively felts manufactured incorporating epitropic fibres to give antistatic properties.

Fabric cleaing

Each filter unit is supplied complete with electro-mechanical shakers which raps Filter Elements thoroughly following a delay after the main fan is switched off. This is all dealt with automatically by a control panel supplied free issue with each unit.

Dust disposal

The unit(s) are manufactured with a valley type hopper to channel the shaken dust into round collection bins. Each has a quick release system allowing easy removal after shaking down to allow the Bins to be taken away for emptying at intervals.
