Hy-Pro Filtration

What Hy-Pro Filtration does

Hy-Pro Filtration, now operating as Donaldson Hy-Pro, is a US-based designer and manufacturer of industrial hydraulic and lubrication oil filtration systems headquartered in Anderson, Indiana. Founded around 1986–1988, the company operates as a subsidiary of Donaldson Company Inc., a diversified industrial filtration conglomerate. Its product portfolio is organized into four core lines: DFE-rated filter elements (HP series using proprietary G8 Dualglass media with βx[C] ≥ 4000 filtration efficiency), fluid conditioning equipment (FSL/FCL offline filtration systems, VUD vacuum dehydrators, COD diesel conditioning systems), filter assemblies (LF/LFM low-pressure high-viscosity housings), and reservoir accessories (Hy-Dry desiccant breathers, ICB varnish and acid scavenging systems). The company's central technical differentiator is its proprietary Dynamic Filter Efficiency (DFE) multi-pass testing methodology, co-developed with Scientific Services Inc. in 1998, which validates filter capture and retention under real-world dynamic conditions — including duty cycles, rapid flow changes, and cold starts — rather than under static ISO16889 protocols.

Hy-Pro serves more than 15 industrial verticals, including cement plants, aluminum processing, steel mills, mining, paper mills, power generation (combustion, steam, hydro, nuclear, and wind turbines), oil refineries and petrochemical facilities, plastic injection molding, and diesel fuel conditioning for backup generators and mobile fueling operations. Documented customer outcomes include a 99.8% reduction in particulate contamination (eliminating approximately $633,000 in annual pump failure costs at a hydraulic valve manufacturer), oil life extension from 45 days to over a year for a drilling operator, and a reduction of servo valve replacements from 220 to 6 per year following ISO code improvements.

The business model is hardware-led and distributor-mediated: Hy-Pro sells replacement filter elements, capital equipment (offline filtration carts, vacuum dehydrators, diesel conditioning systems, filter assemblies), test equipment (PM-1 particle monitor), and reservoir accessories through a global authorized distributor network, with pricing not publicly disclosed and configured per application. The company leverages Donaldson Company Inc.'s 40+ global affiliate companies for cross-border reach across North America, Europe, Asia-Pacific, and Latin America. Marketing is anchored in educational content — blog, Factory Side Chat podcast, ISO code calculators, industry-segmented case studies — and the company rebranded to Donaldson Hy-Pro in March 2024 to formalize its alignment with the parent corporation.

Core offering

Hy-Pro Filtration designs and manufactures industrial hydraulic and lube oil filtration systems, including DFE-rated replacement filter elements with proprietary G8 Dualglass media, offline filtration carts (FSL, FCL), vacuum dehydrators (VUD), diesel conditioning coalescing systems (COD), low-pressure filter assemblies (LF/LFM), desiccant breathers, and portable fluid monitoring equipment. Products are sold through authorized industrial distributors to customers in cement, mining, power generation, steel, aluminum, paper, oil refinery, and other heavy industrial sectors to achieve and maintain target ISO fluid cleanliness codes.

Product overview

Donaldson Hy-Pro offers an integrated portfolio of hydraulic and lube oil filtration solutions organized around four core product lines: filter elements (DFE-rated HP series with G8 Dualglass media), fluid conditioning equipment (offline filter systems FSL/FCL, vacuum dehydrators VUD, and coalescing systems), filter assemblies (LF/LFM low-pressure housings), and reservoir accessories (Hy-Dry breathers). The company pioneered Dynamic Filter Efficiency (DFE) testing methodology in 1998 to validate filter performance under real-world dynamic conditions. Products target industrial sectors including cement, power generation, mining, steel mills, aluminum processing, paper mills, and diesel fuel conditioning. The portfolio spans portable filter carts for field conditioning, stationary offline kidney loop systems, vacuum dehydration for water removal, and diesel coalescing systems—each designed to achieve and maintain target ISO fluid cleanliness codes while extending component and fluid life.
