Versatile control systems provide traceable process conditions for cGMP, FDA, and USP compliance. Monitor and adjust airflow from a central location
Program back-pressure set-point and receive an automated alert when filters need replacing; avoid electrical fire hazards from overworked FFU motors
Use the fan/filter unit challenge port to assist with leak testing and help set the filter replacement schedule based on your operational conditions
Illuminate your room with modular lights including fluorescent, space-saving teardrop, flow-through modules and energy-efficient LED
Our Germicidal UV-C Lamp helps disinfect cleanrooms, labs and aseptic environments. A built-in safety sensor will turn off when motion is detected
Create a homogeneous stream of positive and negative ions to neutralize surface static charges with these Ionizing Bars. Stop ESD before it starts!
Effectively seal unoccupied ceiling grid bays with panels made of application-specific material. They are firmly held in place with ceiling clips
Did You Know?
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 literally 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:

|White Paper (PDF)||Airflow Uniformity and Fan Filter Units
Fan filter units help to remove contaminants from controlled environments. They are effective if designed well. Variables like speed and baffles contribute to an FFU's ability to maintain uniform air speed and direction. Read more about how FFUs help you comply with ISO and other regulations.
|Tech Resource (PDF)||Calculating Clean Room Cleanliness: How many FFUs and Lights?
This tutorial provides practical tips for correlating the desired cleanliness level (per ISO/FS209 standards) to the required number of fan/filter units (FFUs). Also provides guidelines for specifying lights based on the type of operations being conducted.
|Tech Resource (PDF)||HEPA and ULPA Particle Filters
HEPA and ULPA filters remove sub-micron particles from the air, which are too small to see but create BIG problems in many critical manufacturing operations. Read about filter capability and airflow resistance testing.
|Tech Resource (PDF)||Charcoal Filter Life
Unlike HEPA and ULPA particle filters, activated charcoal filters create no additional backpressure when they near the end of their service life. So when do you replace them? Here's how to tell.
