Laminar Flow Absolute Filters (75)

DESCRIPTION
Vira Safi filtration has been designing, testing and manufacturing
custom HEPA filters for laminar flow cabinet hoods. We manufacture
both the pre-filters and HEPA filters and can add an antimicrobial
coating if required to sterilize the air particles caught by the filter.
In many environments, including research, technology and medical
there is always a risk for contamination of samples from the outside
environment. Custom HEPA filters for your laminar hood will ensure
these samples do not get contaminated by their environment or the
operator.
To be used for absolute air filtration in controlled contamination
environments clean rooms, LAF benches and operating rooms.
Available in a variety of sizes.
