CRFF Fan Filter Unit, 24" x 48", Krueger-HVAC (CAT#: STEM-C-0730-ZJF)

CRFF series Fan Filter Units manufactured by Krueger-HVAC combine low noise, energy efficiency and space-saving low profile design for critical environments with requirements of the highest levels of cleanliness.
Modular in design, CRFF series can be used in grid systems with nominal sizes of 24" x 24" and 24" x 48".
By selecting the ARS option, you will be able to remove the perforated face for periodic cleaning. In addition, you will be able to access and replace the HEPA filters from the room side as well.
The units are equipped with an integral continuous knife edge that penetrates the gel-filled pocket of the gel seal filter, resulting in leakproof sealing.
An expanded metal face protects the HEPA filter from unnecessary or accidental contact with the media.
ULPA filters are optional to increase the removal of particulate matter.
The units can be customized to meet your specific requirements.
