40 Inch High Flow Polypropylene Filter Bags
Made in the USA
High Flow 40 Inch Polypropylene Filter Bags are extended-length liquid filter bags designed for compatible large high-flow bag filter housings, including many horizontal high-flow units. With an approximate 7" diameter and 40" length, these bags provide increased filtration surface area compared to standard bag sizes, helping support higher flow rates, longer service life, and reduced change-out frequency in demanding industrial filtration applications.
Made with polypropylene filter media, these bags are commonly used where chemical compatibility, low moisture absorption, and resistance to a wide range of process fluids are important. They are a strong option for applications where standard Size #2 filter bags do not provide enough dirt-holding capacity or where the housing is specifically designed for longer, high-flow bag elements.
• Extended 40" length provides increased filter media surface area
• Approximate 7" diameter for compatible high-flow bag housings
• Polypropylene media offers broad chemical compatibility for many industrial liquids
• Commonly used in large horizontal high-flow filter housings
• Designed for higher flow rates and longer service life compared to standard-length filter bags
• Available in multiple micron ratings for coarse, intermediate, or finer liquid filtration
• Low moisture absorption makes polypropylene a strong choice for many aqueous and chemical applications
• Sewn construction provides a dependable, cost-effective option for general industrial filtration
• Plastic ring top provides secure seating in compatible housings
• Not a standard Size #2 replacement bag — intended for compatible extended-length high-flow housings
Performance Parameters
• Bag length: 40"
• Bag diameter: Approximately 7"
• Media: Polypropylene
• Style: Extended-length high-flow filter bag
• Top style: Plastic ring top
• Housing compatibility: Compatible large high-flow and horizontal high-flow bag filter housings
• Available micron ratings: Varies by selection
• Construction: Sewn filter bag
• Application: High-flow industrial liquid filtration
Important Fitment Note
These are not standard Size #2 replacement filter bags. Standard Size #2 bags are typically much shorter, usually around 32" long. These 40 inch high flow polypropylene filter bags are intended for compatible extended-length or horizontal high-flow bag filter housings that require a 40" long bag.
Construction Materials
These bags are manufactured with polypropylene filter media and a plastic ring top. Polypropylene is commonly selected for applications involving water, chemicals, oils, coolants, and other process fluids where good chemical resistance and low moisture absorption are needed. The plastic ring helps the bag seat properly in compatible high-flow housings.
Filtration Area Breakdown
The extended 40" length provides more usable filter media area than standard-length bags, helping increase dirt-holding capacity and reduce bag change-out frequency. This makes the 40" high-flow bag a practical option for systems that need more capacity than standard bag sizes while still using a relatively compact extended-length format.
Typical Applications
• High-flow industrial liquid filtration
• Horizontal high-flow bag filter housings
• Water and wastewater filtration
• Chemical processing
• Coolants and machining fluids
• Oils and process fluids
• Paints, coatings, and inks
• Food and beverage prefiltration
• General manufacturing filtration
• Applications requiring extended service life and increased dirt-holding capacity
