Kowa Fan Filter Unit


Compound Engineering Plastics
The researches of A 3D turbo fan made by own company which High-efficient/Low-noise/Low-vibration/Average air flow/Non-oxidized and Resistant against alkali acid with fine features.
Product Features
  1. 3D Airfoil turbo fan High-efficient & Low-noise
  2. A 3D turbo fan made by aluminum which pursued the most suitable design by computer analysis.
  3. Flexible change design
  4. The specifications of unit can be designed according to customer’s requirements besides our standard models, example for the modification of main filter type, cabinet materials…etc.
  5. Convenient design of installation 
  6. Pre-filter frame board above unit to make prefilter easy installation and maintenance.
  7. Easy carry/handle friendly design 
  8. The transportation and installation of unit is easy with carrying handle and the outlook of units is pretty.
  9. Multiple safe protect devices 
  10. The overload current protection circuit, abnormal pilot lamp,abnormal signal circuit (common fault output dry contactor:NC X 1 Set),motor temperature control switch protection circuit ...etc. for requirement.
  • As demands of cleanliness with process of semiconductor or LCD manufacturer,you are able to choose the fittest filter of particle diameter, dust collection efficiency, etc. 
  • If you need the filter without B(Boron), We recommend PTFE (Poly Tetra Fluoro Ethylene)filter that is made of material of membrane. 
  • If you must avoid DOP(Di Octyl Phthalate) for testing filter, please inform us to test with silica without water or atmospheric air.
