Seitz® PERMAdur® S Support Sheets
Ideal for high performance and longevity
The Seitz Permadur S Support Sheets afford stable, reusable precoat filtration in plate and frame presses. After filtration, the plate and frame are opened. The filter cake is removed, leaving the Seitz PERMAdur S filter sheet ready for the next run. Made of high-quality cellulose and polyolefin fibers, Seitz PERMAdur S support sheets' production is based on the latest technological and scientific achievements in-depth filter media. Get the support sheets with up to 30 percent longer service life over conventional sheets.
- Reduced appearance of swelling in the DE filter during filtration
- May be removed from the filter intact without risk of damage or tearing
- Retention of wet strength even with repeated hot sanitizations
- Full traceability - Each individual filter sheet is laser etched with the sheet grade, batch number and production date. The packing label includes sheet grade, batch, identification number and a fork and glass symbol.

Suggested Operating Instructions
Handling during installation
- Place sheet over support plate of the plate and frame filter
- For filters with manual tightening device: moisten filter sheets then tighten
- For filters with hydraulic tightening device: tighten up to filter pre-pressure of 30-35 bar (432-507 psi). Rinse the filter with warm water at ambient temperature in a forward flow direction with at a flow of at least 50 L/m2
- Control and adjust the filter to a pre-pressure of 30-35 bar (432-507 psi) and sterilize
Rinsing post filtration
- Flush with water at a temperature of 50-55 °C (122-131 °F)
- Flow in the forward direction: should be at least nominal filter output
- Counter pressure of 0.5 bar (7.25 psi)
- Duration: 10-15 minutes or until the rinse water is clear.
Hot water flushing
- Water temperature: >85 °C (185 °F)
- Flow in the forward direction: minimal nominal filter output
- Counter pressure of 0.5 bar (7.25 psi)
- Duration: until a temperature of at least 85 °C (185 °F) is achieved on the outlet side. Allow the filter to stand for at least 30 minutes with hot water. Open the vent valve on the filter inlet side.
Steaming
- Steam temperature: max 121 °C (250 °F), low-pressure steam
- Duration: 20 minutes
