Industrial Filter Bags

SaniClean’s Strainer Baskets can be used with filter bags.

When using an industrial filter bag (with a Stainless Steel ring sewn into the top of the bag), the bag seats in a “cut-out” of the machined ring welded to the top of the perforated support basket. A filter bag Hold Down Ring holds the filter bag in position while being held in place by the Quick Release Handle.

SaniClean Strainers is pleased to offer a complete line of high-performance filtration bags to choose from. SaniClean’s Sanitary Basket Strainers product line has been designed so that the different sized strainer baskets will accept standard industrial filter bags, and more! We also stock a variety of filter bags for the SaniClean Sanitary Basket Strainers that don’t correlate with industry standard filter bag sizes (see table below) –

Filter Bag Material Selection

Felt Filter Bags – Filtration felt is a low cost disposable media with depth-filtration qualities and high-solids loading capacity. Our experts recommend using only filtration felts with a glazed or singed outer finish to minimize fiber migration from the filter surface. Felt bags are available in micron ratings from 1 to 200 microns.

Monofilament Bags – Monofilament mesh is an extremely strong material woven on precision equipment to ensure consistent pore sizes. It can be reused in a variety of applications. Nylon is the most widely used monofilament material. Monofilament mesh bags are available in micron ratings from 1 to 1200 microns.

Multifilament Bags – Multifilament mesh is a type of low cost, disposable filter media. Multifilament mesh is available in polyester and nylon. Multifilament mesh strainer bags are available in micron ratings from 75 to 1500 microns.

MATERIAL SELECTION – Filter Bags are available in Polyester, olypropylene, Nylon, Nomex, and Teflon.X

BAG DESIGN
• SaniClean’s “standard” micro-filtration filter bag comes with a Stainless Steel top ring ideal for all size strainers.
• For all Polyester Felt filter bags it is suggested that the filter bag material be “singed” prior to fabrication. This added quality step best helps minimize any fiber migration from the outer surface of the bag.
• For all Polypropylene Felt filter bags it is suggested that the filter bag material be “glazed” prior to fabrication. This added quality step helps effectively minimize any fiber migration from the outer surface of the bag.
• As industrial filter bag suppliers, SaniClean’s filter bags can be supplied with handles or pull tabs sewn in, to ease filter bag removal.

FAQ’s

What Are Industrial Filter Bags Used For?

Industrial filter bags are used inside sanitary basket strainers to capture unwanted solids from process liquids while supporting cleaner, more consistent filtration. SaniClean Strainers’ basket strainer filter bags seat inside a perforated support basket and are held in place with a hold down ring and quick release handle. They are especially relevant for food, beverage, pharmaceutical, and other sanitary processing applications that require dependable filtration.

Do Industrial Filter Bags Fit Sanitary Basket Strainers?

SaniClean Sanitary Basket Strainers are designed so different sized strainer baskets can accept standard industrial filter bags and additional SaniClean-stocked bag options. A filter bag with a stainless steel ring seats into the machined ring at the top of the perforated support basket. This design helps keep the bag properly positioned during filtration.

What Is The Difference Between Felt, Monofilament, And Multifilament Filter Bags?

Felt filter bags provide low-cost disposable depth filtration and high solids-loading capacity. Monofilament mesh bags are strong, reusable, and woven for consistent pore sizes, while multifilament mesh bags are lower-cost disposable media available in polyester and nylon. Each media type supports a different balance of particle retention, durability, cleanability, and cost.

How Do I Choose The Best Industrial Filter Bag For A Sanitary Filtration Application?

The best industrial filter bag starts with filter bag material selection, micron rating, solids load, process fluid, viscosity, operating temperature, and pressure drop limits. SaniClean guidance highlights factors such as particle size, fluid type, gasket materials, construction material, line size, and connection style when selecting filtration equipment. For sanitary basket strainers, a properly matched felt, monofilament, or multifilament bag helps balance retention, flow, and service life.
