Laminar Flow Absolute Filters (75)

DESCRIPTION
These Laminar Flow HEPA panel filters are used for absolute air
filtration in controlled contamination environments and many types
of clean room area.Designed for the highest efficiency of air
filtration the panels allow air to pass through micro-fine glassfibres,
that form a paper-like surface, that traps impurities and removes
them from the air circulation. HEPA filters are suitable for the
pharmaceutical, food and electronic industries as well as medical
and healthcare environments as they are designed to trap the
smallest particles of dust and spores but also bacteria so they
are ideal for clean rooms, neonatal incubators, medical laborato
ries and many more areas that require high quality, clean air.
Laminar Flow HEPA differ from our Turbulent Flow HEPA as they
have a narrower profile so allow a smoother flow of air but have
a lower air flow rate.
To be used for absolute air filtration in controlled contamination
environments clean rooms, LAF benches and operating rooms.
Available in a variety of sizes.
