High-temperature resistant metal filter bags for demanding dust extraction environments.
Media performance is a function of fiber properties, fabric construction, and fabric finishes. HL Filter’s knowledge and experience of how these variables interact allows us to determine the most effective filter media solution to meet your requirements related to flow rate, product dryness, cake release, and resistance.
Some factors that influence the right media choice include, humidity, temperature, productivity, system differential pressure, exposure time, wear and tear resistance, and chemistry. Our design engineers and application specialists equipped with sophisticated testing equipment can efficiently troubleshoot specific issues and calibrate to meet our customers’ circumstances.
Our experience in designing and manufacturing custom bags enables us to develop high quality and durable products custom built to meet your specific needs. Special size and design bags are available in all materials and most micron ratings. You can count on our accuracy, dependability and efficiency when filling your custom order.
We manufacture our own felt media for our felt filter bags under 9001:2008 quality systems, resulting in order to order, year to year, reliability and repeatability. Each filter bag is also individually sealed in protective plastic packaging to prevent contamination. Our filter bags are silicone free with sturdy construction and easy installation.
Using the highest quality fiber materials and world-class needling techniques and equipment, HL Filter manufactures a wide range of Polyamide needle felts with high dust-holding capacity and good air permeability. The PI/P84 media has good chemical resistance, but this is endangered under highly alkaline moisture conditions. There is a limited tendency to oxidation through O2 or NO2 at high temperatures.
