Profile: Industrial Filter Manufacturing Limited produces filtration products. We specialize in the manufacture of filter bags. We offer thermally bonded filter bags and oil adsorbent filter bags. Our steel ring felt filter bags have no lumps and no needle holes to give better filtration efficiency. The rings are available in zinc plated carbon steel, stainless steel or polypropylene. Our PolyformSEAL™ retainer, moulded from virgin resins, offers a four point positive seal. It is made from chemically resistant, flexible plastic. This design adapts to most filter vessels, ensuring bypass free filtration. Oil-out laminated polypropylene filter bags are the first line of defense in trace oil removal. This structure combines a polypropylene felt with a polypropylene micro-fibre, laminated together to provide good dirt holding capacity with extended oil removal capabilities. The oil-out filter bags are available in all industry standard sizes with a 25 micron nominal retention level.
