HEPA and ULPA Air Filtration 

Connect 2 Cleanrooms use Fan Filter Units (FFUs), which are the only FFUs combining low sound, low watts and a low profile.  

We use FFUs with a choice of two types of filter media:

  • High Efficiency Particulate Air (HEPA H13) Filter: 99.99% efficient @ 0.3 micron
  • Ultra Low Penetration Air (ULPA U15) Filter: 99.9995% efficient @ 0.12 micron

Measuring only 51 dB (A), it provides one of the lowest sound levels of any FFU in the industry. This is an important factor to consider for providing operator comfort, particularly for large scale cleanrooms which may have the noise of over 50 FFUs running at the same time.

Running at only 200 Watts @ 0.45m/s (230V/1Ph/50Hz), the unit uses less energy than traditional FFUs, lowering operating costs. Cleanroom Energy Standard BS 8568:2013 recommends using high efficiency fans.

The unit maintains a low profile, measuring less than 320mm, which means that the height of the surrounding room can be maximised.


  • Low Sound - improve operator comfort
  • Low Watts - energy efficient
  • Low Profile - reduced height restriction
  • Low Operating Costs
  • Three Speed Switch or Variable Speed Controller
  • Forward-inclined Centrifugal-type Fan
  • Snap-In Prefilter: Allows for easy replacement and maintenance (406mm x 591mm x 13mm).
  • Walkable Plenum (Excluding Prefilter)
  • CE Marked
By increasing quantities of FFU's within your cleanroom you can achieve a higher ISO 14644-1 classification, with minimal disruption and modification to the cleanroom.
