LOFCLEAR high performance filter bags are used for demanding particle removal applications. LOFCLEAR filter bags have a three layer design to provide BETA 100 (99%) efficiency for retaining particles from 4 to 40 microns. Constructed entirely of polypropylene, each layer is sewn together and molded to the crush style sealing ring. The first layer retains larger particles and creates a flow path into the depth filtration layer. The final layer, made from spunbound polypropylene, prevents fiber migration.
The filter layers are made of melt-blown polypropylene with a process that does not require lubricants to ensure they are free from silicone and crater-forming substances. The manufacturing facility has tough quality control proceedures (ISO 9001:2015) to guarantee both performance and product consistancy.
The crush seal filter bag ring welded to each layer of the filter bag creates a by-pass free seal against the support basket and bag filter housing.
LOFCLEAR filter bags are used for filtation of high purity fluids having low particle concentration, removal of gelentious particles and oil adsorption due to the pure melt-blown polypropylene fibers contained in each layer. The geometry of each layer breaks-up gelatinous particles and they become embedded within the depth of the filter media.
