40 Inch High Flow Polyester Filter Bags

High Flow 40 Inch Polyester 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 polyester filter media, these bags are commonly used for general-purpose industrial filtration where strength, temperature resistance, and reliable particulate removal are important. They are ideal 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
• Polyester media provides strong general-purpose filtration performance
• 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
• Strong dirt-holding capacity helps reduce change-out frequency in demanding 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

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 polyester 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 polyester filter media and a plastic ring top. Polyester is commonly selected for general industrial liquid filtration because it offers good strength, dependable particle retention, and broad compatibility with many water-based and process-fluid applications. 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, allowing the bag to hold more particulate before requiring replacement. This can help reduce change-out frequency, improve operating efficiency, and support higher-volume process streams in compatible high-flow housings.

Typical Applications

• High-flow industrial liquid filtration
• Horizontal high-flow bag filter housings
• Water and wastewater filtration
• Paints, coatings, and inks
• Coolants and machining fluids
• Oils and process fluids
• Chemical processing
• General manufacturing filtration
• Applications requiring extended service life and increased dirt-holding capacity
