Filter Fan Units Prevent Infection

Did You Know?
Fan/Filter Units Do More Than Meet ISO Requirements—they also prevent infection.

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. Here is a list of common human pathogens that HEPA/ULPA filters capture and remove from circulation:

Pathogens: Bacteria and Diseases
  • Escherichia coli: Gastrointestinal infection
  • Bacillus anthracis : Anthrax
  • Aspergillus brasiliensis: Sinus infections
  • Francisella tularensis: Tularemia
  • Bordetella pertusis : Whooping cough
  • Mycoplasma pneumaoniae: Pneumonia
  • Chlamydia pneumoniae: Bronchitis
  • Clamydia psittaci : Psittacosis
  • Klebsiella pneumoniae: Opportunistic infections
  • Haemophilus influenzae : Meningitis
  • Coxiella burnetii : Q fever
  • Pseudomonas aeruginosa: Opportunistic infections
  • Actinomyces israelii: Actinomycosis
  • Legionella pneumophila: Legionaire's disease
  • Thermoactinomyces sacchari: Farmer's lung
  • Alkaligenes: Opportunistic infections
  • Streptococcus pyogenes : Scarlet fever
  • Mycobacterium Tuberculosis : Tuberculosis

Explosion-Proof Power Switches

UL-rated explosion-proof switches are connected to the lights and blowers using specialized conduit with potted fittings. All electrical components are sealed to eliminate potential ignition points.

Fan Filter Units Prevent Infection

Cleanroom fan filter units prevent transmission of airborne bacterial, viral and fungal organisms including C. diff, MRSA, E. Coli, Actinomyces, Meningitis and Tularemia.

Explosion-Proof Potted Fittings

Conduit is filled with an expanding cement mixture to isolate explosion-proof components from potential sources of ignition; explosion-proof fittings meet requirements of NEC for Class I, Division 1 hazardous locations.

Pre-Filter Grounding Clip

A grounding wire connects the body of the Explosion-Proof FFU to a metal wireframe embedded in the pre-filter as a safeguard against sparking.

Non-Sparking Direct-Drive Motor

Explosion-proof motors use a non-sparking polypropylene fan and cast-iron brackets attached to the heavy duty rolled steel frame

Explosion-Proof Junction Box

The reinforced junction box of the explosion-proof fan filter unit is built to withstand and contain an explosive reaction within the conduit system.

Air Flow Uniformity

Unique WhisperFlow® FFU baffling system and anodized diffuser plate promote uniform air speed across the filter face.
