HEPA/ULPA/PTFE Fan Filter Units FFU With H13 H14 U15 HEPA Filter

The Fan filter Unit ffu consists essentialy of the housing, a compact fanunit with inlet-nozzle, motor and the HEPA filter cell with filter frame. Special deflectors avoid a bypass flow of the supply air directly into the return-air. The sound absorber reduces fan noise.

Technical Data:

The following additional components at the air-inlet side are available:

Prefilter for coarse particle separation
AMC-Filter for the filtration of gaseous contaminations
Return-air covers for prefilter and AMC filter
Cover return-air duct

If necessary filter cell class H13 to U17 can be used.

The FFU-motors have sufficient reserve capacity to overcome additional system pressure loss due to, e.g. raised floor, return-air ducts, prefilter or AMC filter. The FFU-RA-AC is driven by a special developed single-phase external rotor-motor with internally wired thermal contacts for overload protection. The FFU-RA-EC operates with a electronic commutated external rotor motor.
