Harmsco 801, 921, 931 Cartridges

Harmsco® 801, 921, and 931 Series are highly efficient filter cartridges made of pleated Polyester-Plus filter media for low pressure drop, high flow capability, increased contaminant removal, long filter runs, reusability, and the lowest cost per gallon filtered.

The difference between the 801, 921, and 931 filters is the length and nominal micron rating. The 921 series is double the length of the 801 filter, and the 931 series is triple the length of the 801 filter.
