By itself, air cleaning or filtration is not enough to protect people from COVID-19. You can find HEPA filters in most air purifiers. Prefilters capture airborne contaminants in the rear of the room or hood, and the velocity of the air entering the filters is accelerated to reduce the number of particles that recirculate into the room. Install this PharmaState on your iPhone and then Add to Home Screen, Please update your profile to keep using the website. 4.9.1 Noise level shall be checked by using sound level meter. While in operation, the particle classification is not predefined; it will depend on the nature of the processes taking place inside the zone. PAO: Poly alpha olefin Reverse laminar air flow operates on the principle of providing containment of contaminated air by air movement. It is used to control hazardous emissions of powder, dust or vapour during powder dispensing, drum tipping, product sampling, without risk to the operator or environment, and are available in wide modular range of sizes.
