Filter Usage and Housing Weight
Model Number Development
(1) Filters/Weight: Top number indicates the number of filters required to fill the unit. Bottom number indicates the
approximate weight in pounds of the housing EMPTY. Add 32 pounds for each HEPA/ULPA filter and 2 pounds per each
prefilter to determine approximate weight when loaded with filters.
Add 10% to calculate the approximate rigging weight of housings
