Filter Bags for Industrial Liquid Filtration
A complete range of felt, mesh, high-efficiency, and oil-absorbent filter bags for industrial, chemical, and water treatment applications.
Reliable Bag Filtration for Demanding Water Processes
We supply a wide range of filter bags designed for industrial, chemical, and water treatment applications.
Options include DuoLine felt bags for depth filtration, monofilament mesh bags for high solids, high-efficiency bags for critical applications, and oil-absorbent bags for hydrocarbon removal. Available in multiple sizes, materials, and micron ratings from 0.5 to 1000µm, our bags offer both nominal and absolute filtration. Many models feature multi-layer construction, extended life, and FDA-compliant materials.
We also offer reusable stainless steel mesh baskets for coarse filtration. All bags are compatible with Amazon housings and retrofit options for other systems.
DuoLine Felt bags are manufactured using a needle felt type media providing both surface and depth filtration for maximum dirt capacity. They can be supplied with either polypropylene, PTFE, polyester, nylon or high temperature Nomex media.
These Monofilament bags can be used for both pre and final filtration duties and are very well suited to the filtration of solutions with high solids contents such as paints, emulsions and other chemical and coating processes.
Designed to provide effective filtration for a wide range of applications using a variety of graded filter media.
Designed to provide effective oil absorbing capacity in a wide range of applications using a variety of polypropylene media, there are 2 products in this range: DuoLine HO and DuoLine PA bags.
Designed to be used in standard bag filter housings and to provide cost effective filtration for a wide range of applications. The DuoMesh baskets are manufactured from 316L stainless steel mesh, therefore can be cleaned and re-used time and time again.
