FAQs About Cleanroom Hardware

Q: What is a HEPA fan filter unit?

A: A HEPA fan filter unit is a HEPA filter with a motorized fan and motor controller. They allow for distributed air filtration to be placed in the cleanroom ceiling /plenum providing filtered air throughout the cleanroom without ducting to each HEPA filter.

Q: What did people use before the HEPA fan filter unit?

A: Cleanrooms used customer air handlers to push air thru HEPA filters. This required extensive ducting and regular balancing. It was a very expensive and high maintenance design.

Q: What is an RSR HEPA fan filter unit?

A: RSR stands for Room Side Replaceable. In some applications the customer chooses to replace their HEPA filters very frequently (for example: once a year). The RSR design allows the customer to remove just the HEPA filter of a fan filter unit, leaving the fan and electrical wiring in place. This reduces the time cost and changing the HEPA filter.

Q: What is difference between normal trouffer light and cleanroom trouffer light?

A: Normal commercial lights have factory knockouts for wiring that would allow contamination to enter they cleanroom. Cleanroom trouffer lights are sealed with no knockouts.

Q: What does 4000K and 5000K stand for in cleanroom light specification?

A: Kelvin is the thermodynamic temperature of light. For LED lights 4000K temperature corresponds to off-white. 5000K is whiter and appears brighter.

Q: What are tear drops lights?

A: Tear drop lights are mounted on 2 inch ceiling grid and allow a cleanroom to have 100% HEPA ceiling coverage. They are used for the most demanding class 100 or better cleanrooms.

Q: Why do some cleanrooms have amber colored lights?

A: Semiconductor cleanrooms perform photolithography operations that are light sensitive. They use amber filters to block wavelengths that would expose the photoresist and ruin the pattern.
