Applications
HEPA (Absolute) Filters are used in a wide range
of applications, such as clean rooms, and operating theatres.
Other HEPA Filter applications include research facilities,
electronic and microelectronic industries, nuclear and pharmacutical
industries where a high level of air quality is required.
Clean rooms tend to employ the narrower 146mm deep HEPA Filters
and utilise a lower face velocity in accordance with the relevant
Clean Room Standard.
Description
The HEPA filtration medium is provided by microfine
glass fibres formed into paper-like surface supplied in various grades
depending upon the filtration efficiency required.
HEPA filter paper is formed into a close pleated
package to provide a large surface area offering maximum airflow at
a reasonable resistance. Corrugated spacers of either kraft paper
or aluminium are inserted between each pleat of HEPA
filter paper to provide support for the pleat and also ensure the
entire surface of the HEPA filtering medium is used.
The completed HEPA Filter pack is sealed into the
casing using a polyurethane sealant. After which every HEPA
Filter of Grade H11 upwards is individually DOP Scan tested
to ensure conformity prior to despatch.
