Resflex Series

Summary

Product identification

• Product Line: Resflex Series Resin Bonded Cartridges
• Description: Features a patented breakthrough in resin bonded cartridge design with a unique, proprietary two-stage filtration construction that maximizes particle removal and service life in viscous fluid filtration applications. An outer, spiral prefilter wrap increases cartridge strength and eliminates residual debris, while inner layers control particle removal at the rated size.
• Filter Media: Acrylic Long Stable Fiber; Phenolic Bonding Resin
• Key Features/Benefits:
  • Outer wrap increases surface area and eliminates loose debris and contamination caused by machined products.
  • Extra-long acrylic fibers provide added strength, resist breakage and migration.
  • Phenolic resin impregnation strengthens cartridge for use with fluid viscosities up to 15,000 SSU (3200 cks).
  • Withstands pressure surges up to 150 PSID (10.3 bar) across cartridge (depending on fluid temperature).
  • Double-open-ended one-piece construction eliminates bypass concerns with multilength cartridges and eases change out.
  • Silicone-free construction ensures no contamination to adversely affect adhesion properties of coatings.
• Applications: Adhesives, Chemical Coatings, Emulsions, Organic Solvents, Paints, Petroleum Products, Printing Inks, Process Water, Resins, Waxes.
• Ordering Information Example: RBP5-20 (Resflex Filter Cartridge with 5-micron rating and 20” length).

Operating limits

• Max. Temp. Rating: 250˚F (121˚C)
• Max. Differential Pressure: 150 PSID (10.3 bar)

Mechanical / hydraulic

• Outer Diameter: 2.56” (65 mm)
• Flow rate: 10 gpm (38 Lpm) per 10” (254 mm) length
• Flow Rate and Pressure Drop Formulas:
  • Flow Rate (GPM) = Clean ΔP x Length Factor / (Viscosity x Flow Factor)
  • Clean DP = Flow Rate x Viscosity x Flow Factor / Length Factor
  • Clean ΔP is PSI differential at start.
  • Viscosity is centistokes.
  • Flow Factor is ΔP/GPM at 1 cks for 10” (254 mm) or single length.
  • Length Factors convert flow or ΔP from 10” (254 mm) single length to required cartridge length.
• Flow Factors:
  • 2 µm: 0.08
  • 5 µm: 0.04
  • 10 µm: 0.02
  • 25 µm: 0.012
  • 50 µm: 0.01
  • 75 µm: 0.006
  • 125 µm: 0.0013
  • 150 µm: 0.0010
• Length Factors:
  • 9” (228 mm): 1.0
  • 10” (254 mm): 1.0
  • 19” (483 mm): 2.0
  • 20” (508 mm): 2.0
  • 29” (737 mm): 3.0
  • 30” (762 mm): 3.0
