UFI Off-Line Filter Indicators
UFI Off-Line Filter Indicators are monitoring devices designed to optimize maintenance of auxiliary filtration systems in the FOF series and UOW units. The range includes visual, electrical, and combined LED differential indicators, all set at 130 kPa (1.3 bar). Available with NBR or FKM seals and advanced options such as an integrated 30°C thermostat and ATEX certification for hazardous environments, they ensure precise monitoring of the filter element clogging condition.
UFI clogging indicators are a key component for the efficient management of off-line filters (FOF series and UOW mobile units). These devices detect the differential pressure across the filter element, promptly signaling when the cartridge needs replacement and preventing malfunctions or unwanted bypass conditions.
The range offers several solutions to meet specific system requirements:
For more complex applications or specific environments, UFI offers technologically advanced versions:
Technical Features and Materials
The indicators are manufactured using high-quality materials, with a brass body and seals available in NBR (Nitrile) or FKM (Fluoroelastomer). Electrical SPDT versions support loads up to 4–3 A in DC (14–30 V) and provide a protection rating of IP65 (DIN 43650 connector) or IP67 (M12 connector) for electronic models.
