Pall PFD reservoir vent filter

• 1µm solid particulate removal rating 
• Isolation valve system 
• Sight window 
• Spin-on replacement filter canister

Provides optimum protection against water and particulate ingression into vented fluid systems.
Isolation valve system ensures only air entering the reservoir is directed to the PFD, resulting in longer life. Also, reverse flow through the filter/dryer is prevented, eliminating desiccant poisoning by oil vapor.
