We’ve been building these simple filter indicators for nearly 30 years! They’re trusted by OEMs around the world and provide a visual of the condition of a cartridge. These designs use a standardized 1.75″ bolt pattern that connects to a filter head.
Already have an existing filter design with a flat head? You could consider integrating our DPP750 indicator which uses 4 machine screws to mount directly and tell the filter status. These simple 2 color indicators are inexpensive, but very effective.
Like the design of our bolt on or screw on indicators but don’t have a compatible filter? No problem, you can use one of our special anodized aluminum mounting bases which converts them to 1/8″ NPT connections. They’re perfect for remote monitoring.
Our newest member of the DPP family, the Purigauge offers 1/4 push to connect fittings. We’ve collaborated with John Guest to incorporate their industry leading cartridges. This allows a use to simply cut tubing and plumb up the gauge in minutes!
The bolt on and screw indicators allow users to mount the gauge in either direction. This is critical to any system because it allows the differential to be monitored in either flow direction.
Simple bolt on indicator that is interchangeable with DPP975. Seals by two o-rings onto filter head.
Gauge style filter status indicator. Interchangeable with DPP175. Diaphragm sensing element. Can be outfitted with electrical switch for remote notification.
Screw on filter status indicator. Mounts onto flat filter head. Can have electrical switch output.
Gauge style filter status indicator that uses push connect fittings for easy installation.
Ensure safety and performance of your company’s filter designs by integrating an indicator. Without a visual, operators can have a difficult time knowing when to change the cartridge.
Stop forgetting to change your filter! Our indicators make sure you know the status without having to close the system down. This reduces down time and prevents potential failures.
