Differential Pressure Indicator
Colton’s own purpose-designed product, which indicates when the baskets require cleaning, takes the guesswork out of maintenance. Indicator body has anodized aluminum body as standard. (Stainless steel body and internals also available).

Heating Jacket
To aid the flow of viscous liquids, etc…

100% Shut-Off On Changeover
This can be achieved by the use of a special seal within the changeover plug mechanism and eliminates leakage between chambers during cleaning

Automatic Air Eliminators
To vent air from filter, eg. after element cleaning

Magnetic Inserts
Suspended from the cover to capture metallic particles. Magnets can be nylon coated if required

Mounting Studs or Brackets
To allow the filter to be independently supported.

Pressure Equalizing Valves
Are fitted to sizes 5", 6" and 8" as standard but can be fitted to other sizes on request.
