Learn More: Filter Fan Units Prevent Infection

Did You Know?
HEPA/ULPA Filters Do More Than Meet ISO Requirements - they also prevent infection.

Most cleanroom professionals understand that HEPA and ULPA filters capture contaminants that degrade particle-sensitive samples. But they also help remove bacteria, mold spores, and many viruses 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:

Pathogens: Bacteria and Diseases
  • SARS-CoV-2: Coronavirus (COVID-19)
  • Escherichia coli: Gastrointestinal infection
  • Bacillus anthracis : Anthrax
  • Aspergillus brasiliensis: Sinus infections
  • Francisella tularensis: Tularemia
  • Bordetella pertusis : Whooping cough
  • Mycoplasma pneumoniae: 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

Locking Cleanroom Storage Cabinet with Laminar Air Flow

This HEPA-filtered cleanroom storage cabinet features heavy-duty vertical locking rods to prevent unauthorized access. SDPVC windows provide visibility and perforated stainless steel shelves are adjustable in 0.5” increments for greater space efficiency.

Vertical Laminar Airflow Storage Cabinet for Curing Optical Assemblies

HEPA-filtered vertical laminar airflow storage cabinet provides a Class 100 (ULPA for Class 10) particle-free environment for curing or storing sensitive components like optical assemblies. Perforated shelves allow vertical laminar flow through the cabinet.

Highest Standards For Electronic Components

Terra’s electronic components are designed and built to the highest standards required by defense and semiconductor industries for long-term reliability and protection against damage, injuries, and electrical hazards.

Airflow Uniformity Improves Laminar Flow

Non-uniform air speeds produce turbulence that can recirculate particles into the air stream. Unique WhisperFlow® FFU baffling system and anodized diffuser plate promotes uniform laminar airflow to minimize turbulence and effectively carry away contaminating particles.

Protect Against Contaminants and Pathogens

HEPA and ULPA filters help capture many bacteria, viruses (COVID-19), and mold spores that contribute to a host of infections for both humans and plant/animal tissue cultures

WhisperFlow Quiet Operation Reduces Distracting Background Noise

Exposure to loud noises can lower the ability to focus on work and listen selectively, which may also lead to safety issues. Typical AC units can be annoyingly loud, measuring in the range of 70 dB (comparable to a vacuum cleaner). Terra’s WhisperFlow design produces far lower noise levels for a quiet environment comparable to a library. At 90 ft/min output, units measure under 50 dB from only 1 ft away (roughly 75% quieter than 70dB).

Long Running FFU Motors

Terra’s filter fan unit motors are rated for 5 years of continuous, 24/7 operation, if the HEPA filters are consistently replaced. To accurately monitor your HEPA filter’s saturation levels, purchase Terra’s audible and visual filter replacement alarm system.

Multi-Chamber Laminar Flow Storage Cabinet

Economical ValuLine™ laminar flow storage cabinets provide a ISO 5 (Class 100) positive-pressure, particle-free environment for drying or storage of contamination-sensitive materials. The transparent plastic design provides full visibility to easily find or monitor stored items.

Single-Pass HEPA Filtration with Vertical Laminar Flow

The fan-filter unit mounted on top supplies single pass HEPA-filtration, pressurizing the cabinet’s interior to protect against particle contamination. Doors for each chamber reduce in-flow of outside air and contaminants during material transfer.

Bottom Exhaust Vents for Vertical Laminar Airflow

Slotted chambers help quickly circulate and mix clean air throughout the cabinet to minimize “blind spots” and further dilute particulates inside the cabinet. The bottom doors of the cabinet have air exhaust vents to promote vertical laminar airflow.

Stainless Steel-Reinforced Doors

Stainless steel reinforcing bar provides added rigidity and durability to plastic doors.

Closed-Cell Door Gasket on Reinforced Door

Closed-cell door gasket maintains internal positive pressure when purged with dry gas, and stainless steel reinforcements extend door life

Durable Embedded Static-Dissipative Layers

Terra's SDPVC features bonded dissipative layers that resist abrasion. SDPVC desiccators retain their surface resistivity of 106 - 108 ohms/square indefinitely (unlike spray-on coatings that can wear off after a few years), protecting your materials against ESD damage. Further, the control of static charges eliminates particle attractions, helping maintain clean surfaces.

Self-Closing 316L Stainless Steel Hinges

Self-closing 316L stainless steel hinges use springs to both hold open and help tightly close doors. Stainless steel drastically extends service life and minimizes corrosion, flaking, and contamination that commonly occur with ordinary chrome-plated hinges.

Cleanroom Compliant Swell Latches

Swell latches open/close with the flick of a finger to save wrist strain. An expanding rubber bushing firmly seals doors to prevent dust and moisture from leaking in, plus eliminates corrosion, flaking, and particle contamination from chrome-plated latches.
