Reputable Full-Service Distributor of Filtration Systems

• Designed specifically for gas turbine air-intake or high velocity air-intake applications (e.g., pre-filters for gas turbines and compressors). kochfilter.com+2

• Low resistance to airflow (“low pressure drop”) meaning less restriction of air going into the turbine/intake system. kochfilter.com+1

• Durable construction suited for harsh environments (high humidity, salt spray, desert dust, high velocity air) — Koch positions these filters for use “from hot and gritty desert environments to salty coastal locations to icy arctic applications”. 

• Available in a range of configurations/media: synthetic media pleated panel pre-filters (e.g., Multi-Pleat GT) and high efficiency barrier filters for more extreme conditions.

• For the Multi-Pleat GT model: MERV 8 (in accordance with ASHRAE 52.2) for the standard pleated panel version. kochfilter.com

• Initial pressure drop of less than 0.25″ W.G. for the Multi-Pleat GT in some sizes. kochfilter.com

• For higher-efficiency models in the gas turbine inlet line (not just the GT pre-filter version) Koch offers ASHRAE efficiencies of 65%, 75%, 85%, 95% with MERV ratings 11-16.

• When used as a pre-filter ahead of more expensive final filters (in turbine intakes), the GT series helps extend the life of those final filters. kochfilter.com+1

• Because of the lower resistance to airflow and robust design, these filters can lead to energy savings (less fan power needed) and reduced maintenance/shutdowns. 

  • Example: Koch performed a project where replacing older pre-filters with theirs resulted in ~$156,000 annual energy savings.

• Suitable for retrofits or replacement in gas turbine inlet housings / compressor air intakes / high velocity intake systems.

• FAA Filters, Refilco, and Sefiso provide liquid filtration systems/cartridges/vessels; often the brand lines overlap/integrate under Sefiso.

• If you need very fine micron ratings (0.5-1 µm) for critical hydraulic or lubricating fluids, choose Refilco’s “Ultra Protection” line.

• For general industrial liquid filtration (5-40 µm) Refilco’s “Industrial Grade” line serves well.

• FAA Filters offers broader system solutions including filter vessels/housings and can handle aggressive applications (fuel, solvents, coolants).

• Sefiso as the umbrella means simplified sourcing across media types and applications (liquid + fuel + gas + air) which can be beneficial if you have multiple fluid/fuel filtration needs.

• Important factors in liquid filter selection: micron rating, media type (cellulose vs synthetic), fluid compatibility (oil vs water vs chemical), flow rate, differential pressure drop, vessel/housing design. The specifications provided by these brands reflect these considerations.

• Because these are industrial‐grade filtration systems, attention to installation, change-out interval, operating conditions (temperature, fluid type, contaminants) is critical for reliable performance.

• Refilco is a brand (under the same umbrella) targeting industrial liquid filtration—especially for hydrocarbon, lube & hydraulic fluids.

• The “PL Series” Refilco cartridges: multi‐layer pleated construction; micron ratings available ½ µm up to 40 µm nominal. sefiso.com+1

• Sub-categories:

  • “Ultra Protection” (½ & 1 µm nominal) for critical fluids: insulating oils, servo valves, high pressure hydraulics. 

  • “Critical Service” (1-3 µm nominal) for seal oil, gear oil, fuel injection, final filtration. JM ELS Sales

  • “Industrial Grade” (5-40 µm nominal) for lubricating oil, cutting fluid, fuel oil, low pressure hydraulics. 

• The “PLH Series” by Refilco: synthetic media cartridges (microglass + polyester pleated foil backing) designed for mineral oils, synthetic fluids, water-based fluids and chemicals. sefiso.com

  • Features: higher flow rates, long‐term resistance to water deterioration, wide chemical compatibility, high dirt holding capacity. sefiso.com

• Correct sizing, media selection and housing compatibility stressed for optimum performance.

Filters designed to filter contaminants such as rust, pipe scale, compressor lube oil, and water from compressed gases.

Remove all visible oil mist and smoke from vacuum pump exhaust even when it is saturated with oil.

ASME filter replacement elements designed to incorporate large flow capacities for maximum performance with low differential pressures.

Atomic Absorption (AA) Gas Purifier is an engineered, wall mountable system designed to purify gases commonly used with AA Spectrophotometers. Consisting of two independent filtration systems for purifying compressed air and for acetylene gas.

Hydraulic elements offer superior protection for your engine-powered equipment.

Portable Filter Carts are the most economical way to protect your system from the harm that can be caused by contamination.

Duplex filters are a cast iron or stainless steel filter for heavy duty duplex operation applications that need to stay online during a filter change.

Spin-on lube filters protect your engine from wear particles that can otherwise lead to premature parts failure.

MP centrifuges have bowl discs which greatly improve the efficiency of our products. MP centrifuges are unique in having bowl discs for these types of centrifuges – this feature is not available from any other manufacturer.

MP centrifuges have been designed to eliminate cross contamination between contaminated oil and cleaned oil, from the unique impeller drawing oil in at the base of the units to oil-sealed components. All ensure cleaned oil and dirty oil remain separate.

No matter which unit you require, our units outperform all other competitors by nearly three to one.

The mechanical sealed pumps are financially more economical, due to the shaft seal design. The main difference of the mechanically sealed pump is it’s designation of high or low temperature, with the pump designed to be coupled directly to an electric motor of flange type and, also with options of a pressure relief valve.

Magnaline pumps are magnetically sealed and completely leak free, requiring very low maintenance. As these type of pumps contain no seals, they are very reliable, and entail very low maintenance plans keeping costs to a minimum. Installation is also very easy, as there is no need for alignment of motor/pump.
