RAF-2M Reverse Airflow Dust Collector

Key Benefits
  • Modular design that delivers reliable extraction for today and in the future
  • Extendable as your requirements grow – future proofing your investment
  • Efficient self-cleaning while in operation
  • Very low maintenance and running costs
  • ATEX compliant. Designed to strict European safety and emissions Standards
  • Over 50,000 systems installed worldwide

The RAF filter series are a highly effective self-cleaning baghouse designed to handle high dust volumes and medium air volumes. They are designed for continuous operation and work efficiently by automatically cleaning the filter bags while running.

The RAF-2M typically services up 24,000m3/hour at medium dust load applications. This may equate to 8-12 machines in a Joinery/cabinet maker application.

Each module is fitted with a combined inspection and explosion relief door. A safety switch ensures automatic shutdown in case of emergency.

The medium/large particles are separated in the filter hopper (inlet section optional) and the air is afterwards distributed to the filter bags. The collected material is discharged through the rotary valve or screw conveyor

The 2M comes standard with Rotary Valve for continuous operation (no need to shut down to empty your waste bin), Variable Speed Drive (VSD) for low running cost, 170m2 of the advanced XT15 antistatic filter socks and on-line PLC controlled reverse air cleaning system.

Fan:

The high efficiency main fan is self cleaning & ensures high performance, quiet operation and low running cost. We use large heavy duty 4pole fans  – opposed to the cheaper 2 pole fans.

  • 4 pole fans are larger in construction and runs slowly (typically 1,250-1,480 rpm – ensuring quiet operation)
  • 2 pole fans are smaller and runs faster, typically 3,000 rpm

Modularity:

The RAF-2M is modular by design and the system can easily be extended if your extraction requirements increase in the future.

For heavy waste load applications, we commonly discharge the waste into a silo, container or separate material transport system.

Typical applications:

  • Joinery & cabinet making
  • Timber & Process
  • Paper & Trim
