Applications

Biogas filtration

Biogas filtration

Landfill & digester gas can contain up to 1.5% (15,000 ppm) of sulfur in the fuel gas. This sulfur oxidizes in the engine’s combustion chamber to form sulfur dioxide (SO2). That combines with water (H2O, a by-product of combustion), to form sulfurous acid (H2SO3).  This, in turn, reacts with oxygen (O2) to form sulfuric acid (H2SO4).   A significant amount of these impurities blow past the piston rings and accumulates in the crankcase, acidifying the oil.  The wood fibers in Filtration Systems’ depth-type filters absorb this troublesome moisture, and our “-TSS” treated filters neutralize acidic compounds. 

Dust Collection

Dust Collection

Filtration Systems makes a wide range of dust collect cartridges to fit all popular makes and models of equipment. The cartridges feature heavy-duty construction to withstand rigorous use. We offer three grades of media, to match your application requirements.

Our standard media is an 80:20 Blend of cellulose and synthetic fibers, with a hydrophobic binder, for excellent moisture resistance. There is also a flame-retardant version available. 

Our Spun Bonded Polyester media has unsurpassed strength, making it an excellent choice for back-pulse applications, such as powder-coating, etc. Also, available with an aluminized coating. 

Our Nanofiber Laminate is rated at MERV 14, right out of the box, making it an ideal media for gas turbine filtration units.

Natural Gas Filtration

Natural Gas Filtration

Natural gas is an abundant clean-burning fuel that provides an important part of the overall energy usage in the United States.  Gas (CH4), also known as methane, undergoes a number of processes as it is transported from wellhead to end-user, and many of these steps require filtration of the product.  Impurities such as pipe scale, iron sulfide, hydrates, water, liquid hydrocarbons, sulfur products and carbon dioxide must be removed before it is deemed “pipeline quality”.

Gas-fired engine-compressor sets “gather” the natural gas from the wellheads, and pump it to a gas processing plant to make it marketable.

Railroads

Railroads

Our high-flow railroad lube filters have been used for years in demanding conditions, often over mountainous terrain. They consistently last a minimum of 3 months, and often 1/2 year, between filter change-outs. We have manufactured hundreds of thousands of railroad lube elements, protecting locomotive engines worldwide, with the best value in the industry.

SWIRL FLOW™ Filtration Systems’ patented “Swirl Flow™” depth elements are a dramatic break-through in filter technology. By alternating layers of low and high density media, and balancing the ratio of circumferential to radial flow, the media layers progressively load with dirt, like peeling an onion. The result is an incredibly long-life filter, designed for reliable performance at low cost.

Stationary Engines

Stationary Engines

Filtration Systems has been making filters for large stationary engines for over 30 years.  It is our core business.  Our filters fit all the major engine manufacturers: Caterpillar, Waukesha, Cooper Bessemer, Dresser Rand, White Superior, Worthington, DeLaval, Enterprise, Clark and Nordberg, etc.  We make both the air filters and the oil filters for these engines.

Our air filters are either the panel-type or cylindrical, with sturdy metal components and high-quality gaskets.  We offer both paper media and synthetics, with high-removal efficiencies, low flow restriction and long service life.  Special media are also available, such as flame-retardant, water-repellant, charged-fiber and nanofiber treatment, so we can handle your most demanding application requirements.  We also make cleanable pre-filter wraps for many of these filters, providing a low-cost option to increase the life of your filters.
