The Simple Way to Check a Filter Status.

The DPP175 has been one of our best selling products since its development nearly 20 years ago. It uses the same 1.75″ bolt pattern as the DPP975 indicator and serves as a lower cost option for manufacturers. The indicator comes in a variety of different pressure ranges and uses a simple two color “pop” style visualizer to show when a filter needs cleaning.
