Fan Filter Unit(FFU) is air cleaning equipment to supply purified air to the clean room for manufacturing electronics components, food products, pharmaceuticals , health care or any precision engineering products .The installation space is the system ceiling grid. For a large clean room, a large number of FFU are required depending upon class of cleanliness.


  • Modular Design to change layouts

  • Air Tight Performance
  • Low Noise & Vibration
  • Ductable Design
  • Cost optimization
  • HEPA and ULPA filters (Mostly minipleat) Choose either a HEPA Filter 99.99% eff. @ 0.3 micron or ULPA Filter 99.9995% eff. @ 0.12 Micron filters
  • Various optional accessories like prefilter Diffusion plate,pressure gauge
