SS Pleated Felt Filter Element
Sintered 316L stainless steel fiber felt, pleated for maximum area. High-porosity structure — low pressure drop even at high flow rates and with viscous feeds.
SS Pleated Felt Filter Element
Depth filtration: particles are captured throughout the full wall thickness rather than only at the entry face. This makes performance less sensitive to particle size distribution and gives the element a large dirt-holding capacity before blinding. At the same flow rate, pressure drop is significantly lower than a sintered powder element of equivalent pore rating.
Sintering joins the metal fibers. Particle and fiber release must be assessed under the specified operating, cleaning and backwash conditions; no zero-shedding guarantee is made.

Why Pleated Felt Elements Hold Up in Service
High-Porosity Structure
Fiber felt typically offers higher void volume than sintered powder media — the open structure handles high-viscosity fluids and high-solids feeds with lower differential pressure. Porosity varies by specification.
Depth Filtration
Particles are captured throughout the wall thickness, not just at the surface. Large dirt-holding capacity extends service intervals in variable-quality feed streams.
Sintered Fiber Structure
Sintering joins the metal fibers. Particle and fiber release must be assessed under the specified operating, cleaning and backwash conditions; no zero-shedding guarantee is made.
Cleaning and Reuse Review
Agree cleaning methods and pressure and temperature limits for the specific element. Check the element condition and filtration performance after cleaning; complete regeneration without damage or particle release is not guaranteed.
Up to 400 °C (316L, subject to operating conditions)
Standard 316L elements rated to 400 °C, not recommended above. 304 fiber felt available on request.
Fits Standard Housings
Pleated geometry in standard DOE, 222/226, and custom end-cap configurations to fit existing installed housings.
Typical Duty for Pleated Felt Elements
