Progressive filter bags are manufactured
under strict quality control standards through our advanced
manufacturing process. Bags range in sizes from 1 to 800 micron and are
available to suit a variety of applications.
Monofilament mesh -
this surface filtration media removes particles using its mesh
structure. The fibres are thermally bonded and the mesh material does
not exhibit fibre migration. Micron levels range from 15 to 800 micron.Needle
felt - features a three dimensional structure of high porosity enabling
high flow rate and high particle retention. High quality needle felt
shows a 60-70% filtration efficiency. High quality needle felt with heat
treatment surface has no fibre migration without reducing flow rate.
Melt-blown
non woven - multi-layer melt-blown depth filter media is made from
polypropylene micro-fibre and consits of three layers. The inner layer
is similar to woven polypropylenewhich maintains mechanical stability,
the intermediate layer is melt-blown non woven structure with 90%
porosity with an efficiency level of 90-98% with large particle
retention and the external layer is structured polypropylene needle
felt. This bag shows good absorption capacity of oils and hydrocarbons.
Steel
ring, no ring or Plastic Flange filter bags are available. All
Progressive's bags are ready to use, our style of filter bags are sewn
on the inside of the bag so that you don't have to turn the bag inside
out. We also design our bags so that the bag diameter is bigger than the
ring diameter, thus no tension is applied to the sewn area. This
prevents any damage to the bag and ensures no bypass of liquid through
the bag.Progressive's
plastic flange filter bag with thermal bonded plastic offers 100%
filtering by absolutely preventing bypass. As the differential pressure
increases the integrity of the sealing unit increases.The plastic flange
is available on the polypropylene and polyester range.
