Standard Capacity Medium Efficiency Pleated Air Filter
The Purolator hi-E 40 is a medium efficiency, self-supported,
extended surface, pleated air filter. The media area and initial
air flow resistance have been carefully balanced to withstand flow
capacity up to 625 FPM while maximizing dust holding capacity.
The Purolator hi-E40 is effective in stand alone
applications or as a pre-filter in place of a disposable, permanent,
or media pad/frame filter. In situations where a significantly higher
degree of cleanliness and/or longer service life is desired, a hi-E40
pleated filter should be considered.
