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

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.

Smart WhisperFlow Fan Filter Unit ECM Controls

Smart WhisperFlow® Fan Filter Units are quiet, energy efficient and easily adjustable, either manually or via automatic smart console, for centralized fan speed control and cleanroom pressure balancing.

Fan Filter Unit Control System

Provides room-by-room monitoring and control of Smart WhisperFlow FFUs to maintain target pressure differentials for ISO classification; temperature, humidity and particle monitoring and data logging, as well as dynamic fan set-point control, also available.

Smart WhisperFlow Fan Filter Unit with EC Motor

Smart WhisperFlow® Fan Filter Units feature electronically commutated (EC) motors for improved energy efficiency, low noise, remote speed control and pressure balancing.
