Rosedale Products: High-Capacity Filter Bags for Rosedale Bag Filters

High-Capacity Filter Bags for Rosedale Bag Filters
Fits All Rosedale Filter Housings

Felt Bags-Standard Grade
Felt construction is generally chosen where smaller particle retention is required, in the nominal 1 to 100 micron range. It offers higher solids loading capacity than mesh. General-purpose felt bags are offered in polyester and polypropylene materials. Special-purpose felt bags are offered in polyester and polypropylene materials. Special-purpose felt bags include high temperature service (to 500°F) bags of Nomex® nylon or Teflon®.

Felt Bag Finishes and Covers

 

Standard finish. Plain, as manufactured, without treatment or covers.

 

Glazed finish. The outer most surface fibers are melted by a momentary application of high heat. This bonds the fibers together and reduces the possibility of fiber migration.

 

 

Mesh covers completely encase the felt bag. This cover acts to contain any fibers that may separate from the filter bag. Materials available in mono and multifilament mesh, spun bonded nylon and polyester.

OMesh Bags
Mesh is a woven construction, generally used where micron ratings of 50 to 800 are required.

Two types are offered. The multifilament mesh is a low cost, disposable material offered in polyester. Monofilament mesh has higher strength, and is available in nylon. (It should be considered cleanable.)

Oil Adsorption Bags
For removal of free oil, bags made of polypropylene microfibers, known as oil-adsorb, are available. A size 2 oil-adsorb bag will remove approximately a half-pound of oil from a water-oil liquid. It is only available with a 25 micron rating. If finer filtration is needed in an oil removal task, or high volume oil removal is required, Rosedale's Sorbent Containment Systems are available.

 

 
Melt Blown Media (Microfiber)
Polypropylene melt blown media offers unparalleled adsorption capacity for the removal of hydrocarbon contaminates from liquid streams. The melt blown media is also the heart of the high efficiency filter bag. The small diameter fibers create the bag's ability to remove fine particulate at high efficiencies. Fiber diameter is important because the pore size is a function of fiber diameter, density of fibers, and thickness of materials.
