• Meets NEC requirements for Class I/Class II, Division 1 Hazardous locations
• Non-sparking motor, mounted in a cast-iron, explosion-proof housing
• Uniform airflow of HEPA- or ULPA-filtered air at an average speed of 90 fpm
• Proper installation of explosion proof equipment is critical to maintaining the explosion-proof protection aspects of the system. Therefore all wiring for explosion proof systems should be done in the field per local code by a licensed electrician.
• Room-side-replaceable filter units feature a Gel-sealed filter and easy-open clips to allow fast filter replacement from below without breaching the cleanroom ceiling
• Select HEPA filter (99.99% efficient @ 0.3 µm) or ULPA filter 99.999% efficient @ 0.12 µm)
• Average air flow: 650+ CFM under filter load
• Direct-drive 0.25HP fan-cooled motor is designed for continuous-duty operation
• All FFU data is based on a standalone unit using 1” prefilter and clean filters.
• Data will vary depending on filter media and configurations with other products/systems, such as ductwork or hoods.
Most cleanroom professionals understand that FFUs capture contaminants that degrade particle-sensitive samples. But they also remove bacteria and many viruses and mold spores that contribute to a host of infections.
Most common bacteria are contained by the 0.3-micron pore size of high-efficiency particular air (HEPA) filters. Ultra-Low Penetration Air (ULPA) filters, which are rated 99.999% efficient at retaining particles of 0.12 microns and larger in diameter, capture ultra-fine contaminants, including many large viruses and mold spores.
These filters also remove aerosol-born pathogens—germs that hitch a ride on larger particles and liquid droplets that are captured in a HEPA or ULPA filter. HEPA- or ULPA-based Fan/Filter Units (FFUs) thus can play an important role in infection prevention in surgical theaters, ICUs and other medical settings.
Additionally, HEPA filters can help filter pollen, tiny insects, bacteria, mold, and other fungal spores that might be present during plant tissue culture or cannabis production. Contaminants such as these can find a way in via personnel or normal HVAC units and can blight crops and reduce yields. HEPA Filters help increase crop yields, pass inspection/meet regulations, and reduce contamination.
Here is a list of common human pathogens that HEPA/ULPA filters capture and remove from circulation:
