HAYFLOW™ Filter Bags #1 and #2 size filter bags which last 3-5 times longer!

Filter bags for #2 size bag filter vessels have a 7″ diameter opening and 32″ length, resulting in a total surface area of 5 SQFT, limiting the maximum flow rate to approximately 176 GPM. The HAYFLOW filter bag design has a more complex geometry, increasing its surface area by 50% for a total of 7.5 SQFT. How is that possible?

HAYFLOW filter bags require a special restrainer (support) basket designed to support and position the additional filter bag material. Whereas a standard support basket is cylindrical shaped, having a 7″ diameter opening and either a flat or conical bottom, the HAYFLOW support basket has an additional cylindrical shaped protrusion extending upwards from the bottom center of the support basket. The HAYFLOW filter bag has the same shape and thus its appearance is best described as an inverted basket within a basket.

This ingenious design enables your #2 size bag filer housing to handle higher flow rates and will last from 3 to 5 times longer than conventional #2 size filter bags. Although the HAYFLOW filter bags cost approximately twice the cost of a SENTINEL filter bag, on an annual basis the reduction of filter bags requires coupled with the reduction in labor, downtime and disposal costs add-up to a significant savings. Another cost savings benefit is the reduction of liquid carry-out, which is the volume of liquid retained within a clogged filter bag. A conventional #2 size filter bag holds 4.5 gallons whereas the HAYFLOW filter bag holds only about 1 gallon of liquid; a savings of 3.5 gallons of process liquid per filter bag change! Less retained liquid also equates to a lighter and easier to remove filter bag in support of improved ergonomics.
