Industrial Grade Air Sterilization

Industrial Grade Air Sterilizers in Face Mask or Food Production Factories

We have been getting quite a few requests for quote on industrial grade air sterilizers, specifically for face mask production factory.

We do have industrial grade ceiling or wall mounted air sterilizer. Their deployment is in fact not limited to face mask factory but any hygiene-critical (our food factory job reference as shown in above image) workshops or people-jamming venues.

Aerosol transmission of coronavirus COVID19

Aerosol is ultra-fine droplet of moisture molecules which has been confirmed as a prime vehicle of airborne transmission for coronavirus such as COVID-19 and SARS, as well as various type of influenza A and B viruses.

These fine droplets can suspend in air for hours and travel for tens of meters and beyond. Protect yourself and your kids better by getting to know if there is a sudden increase of PM2.5 (2.5 μm) nearby.
