2' X 4' Clean Room Ffu

Energy Efficiency EC Blower 2' X 4' Cleanroom FFU With Pre Filter


Filter Features


  • Minipleat separatorless HEPA / ULPA Filter
  • All filters factory scan-tested and serialized.
  • All filters are compliant to the requirements of performance standards of EN 1822:2009.
  • Different filter heights available: 50mm(low cost), 69mm (standard), 96mm (extra long life and reduce noise)
  • HEPA and ULPA filters are constructed of pleated glass fibers which are glued into an aluminum frame.
  • The aluminum frame is gasketed to form the final filter assembly with a single-piece gasket that reduce the posility of leakage / gasket damage.
  • The numberous advantages of the mini-pleat separatorless filter technology over the conventional aluminum separator filter technology include: Compact size that contains more pleat per unit of filter surface area. Increased media area with more effective dust holding and longer filter life.
  • Filter aluminum frame that is lighter than the conventional wooden frame used in aluminum separator filter technology. The aluminum frame also eliminates the possibility of swelling in moist conditions present with conventional wooden-frames.
  • Eliminates the possibility of filter damage by aluminium separators.

General Features


  • Lightweight, corrosion-resistant construction is completely smooth and cleanroom-compatible.
  • Permanently lubricated, direct-drive centrifugal blower.
  • Industry exclusive blower technology operates at higher energy efficiency levels with larger airflow volumes.
  • Proprietarty construction technology creates better airflow uniformity across the entire filter face for superior laminar flow and product protection.
  • Choose from conventional AC or energy efficient EC blowers depending on the requirements of your specific clean air application.
  • Standard blower speed controller allows for easy adjusting of the FFU speed controller
  • Improved mounting techniques and sound insulation materials reduce blower noise for increased operator comfort and productivity.
  • Quiet operation of less than 58dBA (measured at a distance of 1m from the unit at the standard airflow velocity of 0.45m/s or 90 fpm with stardard AC blower).​
  • Integral HEPA / ULPA filter: different filter types available on request.
  • Integral metal faceguard protects the HEPA / ULPA filter from damage during installation and transporation.
  • Fan inlet guard grille ensure operator safety during installation and prevents large objects from failing into the casing and damaging the blower. Fan inlet duct collar is available upon request.
  • Choose from a variety of exterior construction materials and styles depending on the requirements of your specific clean air application.
  • Unique modular one-piece blower and electrical assembly is designed be serviceable and easily replaceable at lower maintenance costs.
  • Standard unit shipped with 3 core electrical wires. Power cord is optional. Specify when ordering.


Exterior Construction Materials


Choose from the following exterior construction materials to suit your requirements.


​​(G) Galvanized Steel

Galvanized steel construction provides a more economical alternative when external apperance is not the most important factor. Klair only uses the highest grade steel coated in order to prevent rust and corrosion. This material may be recommended when cost is of the highest priority and when the fan filter unit is used in applications such as the construction of cleanrooms.


(A) Aluminum

Aluminum construction is the most common material of choice and provides a cost-effective solution for all fan filter unit applications. Aluminum is light-weight, corrosion-resistant, will not generate particles, and is thus cleanroom-compatible.


(P) Powder-coated Steel

Construction in coated steel with an abrasion-resistant powder coated finish. This exterior finish provides a visually attractive, durable, smooth and totally cleanroom compatible finsih. Recommended when the fan filter unit is exposed to exterior view such as in the construction of modular clean air devices and laminar flow cabinets, and when custom colours are required. Cost is approximately the same as aluminum construction.


(S) Stainless Steel

Construction in stainless steel, this exterior finish provides a visually attractive, durable and smooth finish. Recommended when required for pharmaceutical applications, and is the highest in terms of the cost.
