Individual Filter Fan Units (CWIC® modules) can be connected to form different size cleanroom ceilings, e. g. for machine enclosures, clean benches or clean work cabins.
The modular design enables fast and low-cost cleanroom construction that can be suspended from the ceiling or supported from the floor by pedestals. Depending on the load of additional components, a range of 4800 mm without support pedestals or suspensions is possible.
The following cleanliness classes can be achieved:
ISO 1 to ISO 8 according to DIN EN ISO 14644-1, as well as class: A, B, C or D according to EC Guide (GMP).

A CWIC® module consists of an outer, torsion-free housing, the installed HEPA / ULPA filter and fan motor unit with a common inner housing. The units are accurately screwed together on the sides as shown. The filter cells can be exchanged from below. A gel seal between the filter frame and the inner housing is used.
The CWIC® housing is made of powder-coated steel or stainless steel in order to meet the high hygienic requirements and corrosion-resistance. PVC curtains or acrylic panels can be used to enclose the clean work-area.
The CWIC® module with the integrated fan takes in the ambient air and presses the air through the HEPA / ULPA filter into the clean work area, flushing the area with clean supply air as a vertical, uni-directional airflow. Contaminations in the work area are moved out downwards.
Depending on the requirements, filter class H13 to U17 can be applied. The CWIC® AC and CWIC® AC Hygiene are driven by a specially developed single-phase external rotor AC motor with internally wired thermal contacts for overload protection.
The CWIC® EC and CWIC® Hygiene EC are driven by an electronically commutated external rotor motor.
