bags have a sewn construction and made from virgin material
whereas Felt Unibags are made from recycled materials and have a
welded construction. All the felt materials provide depth
filtration. The monofilament and multifilament mesh

are made from a premium material and cost about
twice the cost of Sentinel filter bags, however they tend to
last 2 -3 times as long! This is because Duragaf
filter bags are made from a thicker material of smaller diameter
fibers. Using Duragaf filter bags can reduce your disposal
cost and the amount of labor time spent changing filter bags.

layers of nonwoven continuous fibers for enhanced pore size and
weight control. These relatively expensive filter bags are
primarily used by the microelectronics, pharmaceutical and

or eliminates the need for multiple stage filtration (using
multiple bag filters for several particle size ranges.
Max-Load filter bag
designs have up to 10 times the solids
loading capabilities than standard Snap-Ring and Sentinel style
filter bags and therefore are changed less frequently, reducing
both labor and disposal costs. Lofclear utilizes a

Duragaf style filter bags. They require a special support
basket but they almost double the particle retention capacity.
While we have a huge range of designs available, its nearly
impossible to compare different brands of filter bags because
each manufacturer uses different material thicknesses and fiber
size/density specifications, so often you will want to order a
few free samples to try.
