Flexible and Affordable
Canister Filter Systems


We make choosing the right systems easy by helping you design your ideal liquid filtration set-up in a methodical step-by-step process. Our filter experts will be happy to work with you and help you determine exactly what you need. The information below can be used as a guide for navigating some of our most popular options.

Liquid Filtration System Set Up

Single Canister Filter

Single Filters

Single filters are the most cost-friendly way of filtering liquids. Single filters work for lower volume operations that do not require continuous flow.

Duplex Canister Filter

Duplex Filters

Duplex filters permit continuous operation because flow can be switched back-and-forth between two filter vessels during regular maintainance.

Series Canister Filter

Series Filters

Placing filters in a series allows for multi-step filtration. The first filter targets larger particles, and each subsequent filter targets smaller pollutants.

Canister Housing Size


Housing filter options for versitility and effectiveness.

Superior housings are for filtering and straining liquids from one micron to over 800 microns. The most popular sizes for the baskets (also known as filter canisters) is either 4" or 8". The flow rates, pressure drops, and pipe sizes vary between sizes.

Superior Filters can accomodate a range of gauge and vent ports as well as cover styles. Housings can also come with optional pressure gauges.

The baskets and canister housings come in the SF-04 and SF-08 models.

Pressure Drop

Basket strainers and bag filters are usually selected so that the pressure drop does not exceed 2 psi when they are clean. Higher pressure drops may be tolerated when containment loading is low. The pressure drop data is accurate for all housing with strainer or filter bag baskets. When filter bags are added, total pressure drop becomes the sum of the pressure drop as determined below:


Viscocisty (cps)

(H2O) 1 50 100 200 400 600 800 1000 2000
All unlined baskets .65 .85 1.00 1.10 1.20 1.40 1.50 1.60 1.80
40-mesh lined .73 .95 1.20 1.40 1.50 1.80 1.90 2.00 2.30
80-mesh lined .77 1.00 1.30 1.60 1.70 2.10 2.20 2.30 2.80
100-mesh lined .93 1.20 1.50 1.90 2.10 2.40 2.60 2.80 3.50
200-mesh lined 1.30 1.70 2.10 3.00 3.40 3.90 4.40 5.00 6.80

Part A.

Using the desired pipe size and approximate flow rate, determine the basic pressure drop from the appropriate graph above.

Part B.

Multiply the pressure drop obtained in Part A by the viscosity correction factor found in the table above. This is the adjusted (clean) pressure drop for all baskets without filter bags.

Cover Styles

Covers are available in a variety of styles from Quick Clamp to 3- and 4-Eyebolt covers for SF models up to 8 inches. SF-04 and SF-08 are available with over-the-top inlet (goose-neck) covers as well as the top-side inlet.
