The FPP series in-line filter is ideal for use with our parts beginning with QB, QPV, MPV, MM and GX electronic pressure regulators.

• Easy installation
• Compact size
• Low pressure drop

Compact FPP Series filters provide protection from air line contaminants that may be present. We highly recommend the use of these filters with all Proportion-Air electronic pressure regulators or any device that may be sensitive to contaminants.

When using this filter, please only use the thread sealant provided. Proportion-Air strongly advises against using any other thread sealant such as Teflon tape unless the device is being used for oxygen service. Use of Teflon tape can result in small pieces migrating into the valves which can cause the valves to leak.
