Automatic self-cleaning

AFR

The AFR Industrial Filter is a unique, expandable circular design for increased capacity in a compact one-square-meter footprint. The AFR-Series is ideal for high volume, low viscosity applications with retentions as low as 2 microns. It also uses cleanable media that reduces life cycle costs and maximizes productivity.

Technology
Backwashing
Total Volumetric Capacity
4-4.8 gal (15.1-18.1 liters)
Operating Pressure
250 psi (17.2 bar)

核心功能

  • Solids removal from 2 to 1,700 microns
  • Versatility with a modular design that enables future capacity and configuration flexibility.
  • Single system Flow rates up to 3,000 gpm (681 m³/hr)
  • Smooth pipe and nozzle connection transitions to avoid dead spots in the fluid stream and minimize pressure drop.
  • A broad selection of filter media materials and retentions suitable for a wide range of applications.
  • Proprietary 3-way, full-ported valves allow fast, frequent sequencing and maximum cleaning force during backwashing.
  • Isolated top-to-bottom backwash flow ensures complete and efficient media cleaning while continuing to deliver filtered product downstream.
  • Numerous automated backwash options for operator-free service and minimal backwash effluent (<2% of system volume).
  • Available ACCUFLUX media is 98.6 % efficent
  • Configured with an array of up to eight - 4" (101.8 mm) or 6"; (152.4 mm) body tubes surrounding a central cleaning valve

Applications:

  • City water lines 
  • Hot condensate 
  • Chiller water 
  • Fresh water
  • Whitewater / shower water 
  • Cip fluids 
  • Papermaking wet end starch 
  • Pelletizer water 
  • Single and duo tubular filters for a wide range of applications up to 1000 psi and high viscosity applications
