As filter baskets become clogged with debris, the pressure drop increases. In order to maintain efficient filtration and line pressure, it is important that baskets are cleaned regularly.

The differential pressure indicator is designed to monitor basket conditions and provide visual warning that cleaning is required.

This product is available as an optional on all single, dual and self cleaning filters. The indicator is mounted directly on to the filter body and reveals the differential pressure across each basket.

Main Features

• Easy to read
• Compact Design
• No pipework to become clogged
• Positive seal separates clean and dirty liquids
• Remote operation via electrical signal available if required
• Specifically designed for Airpel Filters

Differential Pressure Indicator Specifications

• Anodized aluminium casing and nitrile diaphragm for water and oil applications.
• Stainless steel casing, stainless steel internals and viton diaphragm for other liquids.
• Indicator preset at 10 psi. Other spring ratings available on request.
• Pointer operated by internal magnet which avoids leakage through seals

Other Options and Spare/Replacement Parts for Airpel Filters and Strainers

• Heating jackets — for constant temperature processes to aid flow of viscous liquids.
• 100% shut off on dual filter changeover — this can be achieved by use of a special seal within the changeover cock mechanism and eliminates leakage between chambers during cleaning.
• Magnetic inserts — suspended from the cover to capture metallic particles. Magnets can be nylon coated if required.
• Pressure equalizing valves (dual filter only) — Are fitted to sizes 150 and 200mm as standard but can be supplied on other sizes if required.
• O-rings & seals — To meet specific chemical or low/high temperature applications.
• Custom-designed elements & baskets — Made according to process needs.
