Part # FA100
– HEPA Filter
The HEPA filter is 99.97% efficient in removing particles as small as 0.3

from an airstream.
Particles of this size are respirable and can cause significant respiratory problems.
Replacement:
A HEPA’s service life is determined by the volume of sub-micron particles remaining in the airstream after
passing through the pre-filters. When properly protected, and depending on loading, HEPA filters often provide
months of service. Average service life is 2-4 months.
Part # FA201D
– Gas/Odor Filter
Most process plumes contain several gases, some odorous
– some not, some toxic at elevated concentrations –
some completely harmless regardless of concentration. To ensure employee safety the type and concentration
of pollutants must be determined. Please contact Fumex Engineering for filter selection assistance. These filters
utilize a blended activated carbon and activated alumina impregnated with KMnO4 filter to capture and treat
gases/odors. This combination of materials provides protection across a broad range of gases commonly found
in industrial manufacturing processes.
GENERAL MAINTENANCE
1) The blower motor(s) is a sealed unit, 24,000 hr. MTBF rated. It is permanently lubricated and does not require
oiling
– keep it free of dust accumulations to prevent overheating.
2) Remove any loose accumulations of dust/debris from the air filter chamber periodically.
