After more than 35 years in the filtration industry, Knight Corporation continues to demonstrate improvement in manufacturing processes, technology, and expertise.

The filter bag sizes we carry in stock are P1, P2, P3, P4, P5, P6, P7, P8, P9, P12, PC1, PC2, C1, C2, and RP bags. Our stock bags handle flow rates up to 10,000 gpm and are available in most materials.
Extended Life Liquid Filter Bags (XL)
As the name suggests, Knight Extended Life Liquid Filter Bags are designed to give longer service life, therefore reducing operating costs and process downtime. Knight “XL” filter bags are available in a variety of sizes and materials.
Oil-Thirsty and Oil-Sorbent Filter Bags
This bag is the answer to removing trace oil and grease from an industrial stream of aqueous-based fluids. To better meet your needs, the Knight Oil-Thirsty Bag can be designed to remove from 2 to 16 lbs of oil by increasing layers or adding Oil Thirsty strips, which add to the surface area and increase efficiency, structural strength, and filter life.
Our Oil-Thirsty Bag is designed with a cover for the prevention of fiber migration and includes reinforced lift handles to facilitate its removal. If waste storage is a problem, the Oil-Thirsty Bag can be completely disposed of by incineration.
The ideal oil removal system includes the combination of the Knight Oil-Thirsty Bag, which acts as an oil load prefilter, and the Knight High Efficiency Bag (KHE 300 series), which acts as the final polish filter.
