About Filters and Particle Sizes

About Filter Bags

Seamless

Sewn

Use these bags with a filter bag housing to remove contaminants from your water line.

Seamless filter bags provide more uniform filtration than filter bags with a seam. They trap very fine particles that can pass through the pinholes in a seam.

Felt filter bags have higher debris-holding capacity than mesh filter bags.

Long-Life Filter Bags for Water

Sewn

Replace your filter bags less frequently—these have greater debris-holding capacity than standard filter bags. Use them with a filter bag housing to remove contaminants from your water line.

Sewn filter bags are made of two separate bags; the inside bag traps large particles and then the outside bag traps small particles.

High-Purity Filter Bags for Water

Also known as absolute-rated filter bags, these remove 99 % of particles. They provide more consistent particle removal than other filter bags and have high debris-holding capacity for a long service life. Use them with a filter bag housing to remove contaminants from your water line.

Fabric filter bags hold more debris than felt filter bags.

Stainless Steel Filter Bag Housings

These filter bag housings resist corrosion for a long service life in harsh environments. They have a high-flow capacity for filtering large quantities of material. Housings come with a strainer basket to support a filter bag (sold separately). They have a threaded drain with a plug for easy cleaning. Bolt the legs to the floor for stability.

304 stainless steel housings offer very good corrosion resistance.

Housings with eyebolt cover provide a tight seal.

Housings with clamp cover allow for easy access to the filter bag for quick replacements.

The optional strainer baskets (sold separately) are for use with Styles A and D. Only the baskets with 9/64" perforations will work with a filter bag.

To Order: For optional perforated strainer baskets, please specify the opening size: 1/16”, 9/64”, 3/16”, or 1/4”. For optional mesh strainer baskets, please specify a mesh size: 20 × 20, 40 × 40, 60 × 60, 100 × 100, or 150 × 150.
