Filter Element delivers high flow rates.

Press Release Summary:




HAYFLOW(TM) consists of 2 concentric cylinders, made of polypropylene or polyester extended-life, needle-felt media, with SENTINEL sealing ring for positive seal. Fabric welding technology forms layers with no-by-pass seam. Diameter of cylinder is same size as standard filter bag to facilitate retrofitting into existing systems. Surface area is 70% greater than standard filter bags. High flow rates allow reducing size of filter vessels in new systems by as much as 50%.



Original Press Release:



New Welded-Fabric Filter Element Offers Higher Flow Rates, Longer Life... and Lower Cost



Offering the best of both bag and cartridge filtration, the new
HAYFLOW(TM) filter element from Hayward Industrial Products, Inc.
is based on a patent-pending design that delivers either high flow rates in compact vessels or an extended lifetime and lengthened changing cycles in standard-sized vessels...at a reduced cost.

The heart of a HAYFLOW filter element is two concentric
cylinders of high quality extended-life Hayward filter media. The layers are formed using a unique fabric welding technology to create a no-by-pass seam. The diameter of the cylinder is the
same size as a standard filter bag so retrofitting into existing
systems is easy. The element also features Hayward's patented
SENTINAL® sealing ring for a positive seal.

With up to 70% greater surface area than a standard filter bag,
filtration system operators and designers can enjoy reduced
operating costs using HAYFLOW elements with existing, standard
size vessels. Because of the high flow rates possible with
HAYFLOW elements, it's also possible to reduce the size of the
filter vessels in new systems by as much as 50%, thus lowering
the initial cost. HAYFLOW elements give filtration users an
opportunity to reduce operating costs or initial systern cost.

In operation, the process fluid enters the inside of a HAYFLOW element, passes through it, and exits through the vessel outlet. Unlike cartridge filters, the filtered out material stays inside a HAYFLOW element, not on the outside, so changing a filter takes little time and presents little chance of contaminating the process line. And, in many applications changing a HAYFLOW element is physically easier than changing a standard filter bag.
That's because the HAYFLOW element only retains 25% of the residual liquid volume of a similarly sized filter bag so a HAYFLOW element can weigh up to 75% less than a filter bag. This lower retention volume also means less saleable product has to be discarded with each filter media change and disposal costs are reduced as well.

Standard HAYFLOW filter elements are available in both polypropylene and polyester extended-life needle-felt media with a SENTINEL sealing ring. These two materials are very versatile and will perform well in a majority of applications over a wide range of temperatures. For special applications HAYFLOW elements are available with other media choices. Basically, any weldable filtration media can be use to construct a HAYFLOW element for your application. Multi-layered construction is also possible for applications that require it. Using melt-blown polypropylene media, HAYFLOW elements are available with high micron retention ratings, and with selective absorption characteristics as well.

Changing over from ordinary bag or cartridge filtration to HAYFLOW filtration couldn't be easier. No new filter vessel is required. Existing vessels need only to be fitted with a new HAYFLOW restrainer basket for instant compatibility. No tools, special equipment or modification to the vessel is required. Just drop in the new basket, and the system is ready to go back on-line.
