HEPA Filters

Since its inception in 1991, Nationwide, along with its sister companies in Fenchurch Environmental Group, has become the largest UK manufacturer of HEPA filters.

 

HEPA FILTERS: Function

High Efficiency Particulate Air (HEPA) and ULPA filters are used in areas where extremely high levels of cleanliness are required. They can be used in AHUs or fitted into terminal housings located in the ceiling of a room, while their use in laminar flow benches, fume cupboards and safety cabinets provide protection much closer to those working in the area. Where the contaminant to be collected is considered highly dangerous the filters will be installed in a Safe Change System rather than a standard air extract system.

HEPA FILTERS: Selection & Operation

The selection and use of HEPAs is generally determined by the nature of activity and level of air cleanliness required or, if used in an extract system, the toxicity of the contaminant that could be expelled to the atmosphere. In certain industries, such as pharmaceuticals, international standards may apply with requirements set by the FDA.
Although not always a requirement within a particular industry, it is nevertheless a recommendation that these filters are tested upon arrival and installation at site, and validated as performing to the level required.

SAFE CHANGE SYSTEMS

These are predominantly used on extract systems where the contaminant collected is likely to be highly toxic and should not be released to the atmosphere under any circumstances. They are therefore associated with the nuclear power industry and laboratories in hospitals, universities and the pharmaceutical industry.
