PTF Series Fluorocarbon Lined Tubular Backwash Filters

 Tubular-Backwash-PTF-Internal
Durco Filters PTF-7 Inline Filter

Durco Filters PTF Lined Tubular Filters provide extra protection for corrosive liquid filtering when extreme chemical resistance is required. These high flow rate continuous filtration systems can remove a wide range of particle sizes with automatic backwashing capability. All wetted parts are lined with PTE.

Like the TF series, PTF Lined Tubular Backwash Filters are available in Single Tube (PTF-1), Double Tube (PTF-2), and Multiple Tube (PTF-X) configurations to match flow rate and application requirements.
