Oil Filtration Systems

What Oil Filtration Systems does

Oil Filtration Systems (OFS), founded in 1999 and headquartered in Boerne, Texas, designs and manufactures oil and fuel purification equipment for industrial customers, and is a privately held subsidiary of Clark-Reliance, a diversified industrial conglomerate. Its core technology centers on Vacuum Dehydration Oil Purification Systems (VDOPS) that remove free, emulsified, and dissolved water, particulates, varnish, and entrained gases from turbine, hydraulic, gear, and fuel oils using high-efficiency pleated microglass filter elements rated Beta>1000 across multiple micron sizes. The product portfolio spans vacuum dehydrators, Varnish Removal Systems (VRS) using granular adsorbent and depth media, high-flow filter skids (up to 2,000+ GPM), portable filter carts, fuel coalescer systems, bearing lube oil systems, portable fluid analysis kits, and replacement filter elements, including proprietary Permanent Dispersion Media (PDM) cartridges and claw-style vacuum pump retrofits for high-viscosity applications (ISO VG 220-680) and phosphate ester/Fyrquel compatibility.

OFS generates revenue through four streams: (1) one-time equipment sales of custom-engineered systems built in Boerne; (2) recurring equipment rentals from the industry's largest fleet of 250+ units, including 80 dehydrators and 45 flushing skids, with same-day shipment and hot-shot delivery; (3) field services delivered by OSHA- and MSHA-certified technicians including high-velocity oil and fuel flushing, oil filtration and dehydration, reservoir cleaning, varnish removal, and fuel coalescing; and (4) equipment upgrades and refurbishment (claw-pump retrofits, air-cooled heat exchanger upgrades, PDM cartridge installation) carrying factory warranty. Distribution is direct via enterprise field sales with quote-based custom pricing, supported by six North American depots (Boerne TX, Strongsville OH, Natchitoches LA, Gaffney SC, Hartford CT, Cambridge ON). Marketing is layered on top through a blog, video library, webinars, LinkedIn, YouTube, and email newsletter.

The company serves industrial customers across power generation, petrochemical and refining, pulp and paper, oil and gas production, plastic injection molding, steel manufacturing, cement production, and mining. Documented enterprise customers include Timet (Titanium Metals Corporation), SouthWire, BioKem Oil Services, Aircraft Tooling Company, Kimbro Oil Company, a Texas aluminum extrusion manufacturer, and an industrial gas plant in Rio de Janeiro, with quantified outcomes such as reclaimed 30,000 gallons of hydraulic oil yielding $450,000 in annual savings, $50,000+ in restored metalworking oil, and MPC varnish reductions from 53 to 7 in four weeks. OFS maintains a mutual referral relationship with Enervac, a fellow Clark-Reliance subsidiary specializing in transformer oil and SF6 gas purification, expanding addressable scope without direct sales overlap.

Product overview

Oil Filtration Systems (OFS) manufactures a comprehensive portfolio of oil purification equipment organized around three core system types: Vacuum Dehydration Oil Purification Systems (VDOPS) for water removal, Varnish Removal Systems (VRS) for varnish mitigation, and filtration equipment (filter skids, filter carts, coalescers) for particulate removal. These core systems are complemented by specialized products including Bearing Lube Oil Systems, Fuel Filtration & Coalescing Equipment, and Portable Fluid Analysis Kits. OFS also offers the industrys largest rental fleet of over 250 units (including 80 dehydrators and 45 flushing skids), field services (high velocity oil flushing, reservoir cleaning, varnish flushes), and equipment upgrades/refurbishment. All systems utilize high-efficiency pleated microglass filter elements rated Beta>1000 to meet or exceed OEM cleanliness specifications including ISO 16/14/11 and water content below 20-100 PPM depending on application.

Direct peers

• C.C. Jensen (CJC): Danish-headquartered global leader in offline oil filtration for hydraulic and lube oils, with deep installed base in wind, power, and marine. Closest direct competitor to OFS, competing head-to-head on filter cartridges, kidney-loop systems, and condition monitoring for industrial lubricants.
• HYDAC: Global hydraulic and fluid power component manufacturer with strong offline filtration, condition monitoring, and tank-side systems. Directly comparable to OFS in hydraulic and lube oil kidney-loop filtration, with a more extensive international footprint and broader fluid power line.
• Velcon Filters: Specializes in fuel filtration and coalescer systems for aviation, military, and industrial fuel storage. Directly comparable to OFS in diesel fuel polishing/coalescing and is a more focused fuel-filtration competitor to OFS's Fuel Filtration & Coalescing product line.
• Filtra-Systems: Manufacturer of industrial filtration and separation equipment including filter housings, skids, and custom-engineered systems. Directly comparable to OFS in custom filter skids, filter housings, and engineered filtration systems for industrial fluids.

Broad incumbents

• Pall Corporation: Subsidiary of Danaher; one of the largest industrial filtration companies globally, serving oil & gas, power, aerospace, and process industries. Overlaps with OFS in lube and fuel oil filtration, but operates as a broad incumbent with much larger scale, OEM relationships, and a connected services portfolio.
• Donaldson Company: Large U.S. filtration manufacturer with extensive industrial and OEM coverage including hydraulic filtration, lube oil filtration, and condition monitoring. Competes with OFS in industrial fluid purification but at much larger scale and broader product portfolio.
• Filtration Group: Portfolio of industrial filtration brands (Porex, AG Industries, Global Filter, etc.) serving power, oil & gas, and process industries. Overlaps with OFS in industrial fluid purification, but operates multiple specialized brands rather than focusing on a single integrated oil-purification platform.
• Parker Hannifin (Industrial Filtration): Diversified motion and control technologies leader with a substantial industrial filtration division covering hydraulic and lube oil filtration, condition monitoring, and OEM integration. Competes with OFS across multiple product categories but is significantly larger and more diversified.
• Eaton (Filtration Division): Global power management company with a well-established industrial filtration portfolio serving hydraulic, lube, and process applications. Overlaps with OFS in industrial fluid purity, with stronger global distribution and a wider product line.

Emerging players

• Alsco Industrial Services: Industrial cleaning and fluid management services provider that, like OFS, offers on-site oil filtration, flushing, and tank cleaning as a service. Comparable in the field-services and oil reclamation layer, though smaller and more focused on a regional footprint.
