Watch Us Grow!

AJR Filtration, Inc. is pleased to announce the expansion of our business into our new 140,000 sq. ft. filtration headquarters at 1500 Harvester Road in West Chicago, IL.  Keeping pace with the sustained rapid growth of our business, the West Chicago expansion follows the 2017 inauguration of AJR Group's 180,000 sq. ft. home office and production facility in St. Charles, IL.

The West Chicago location will be the dedicated manufacturing center for filtration products.  In addition to producing AJR's broad line of bag and cartridge liquid filters and bag, pleated bag, and cartridge dust filters, Delta Pure Filtration operations have been consolidated from Ashland, VA.  The addition of Delta Pure's quality line of string wound, melt blown, carbon, resin, and hybrid filters expands the product opportunities for our business partners.  Merging our manufacturing operations under one roof allows the company to create efficiencies, reduce lead times, deepen on-hand inventory levels and guarantee our reputation for quality products and competitive pricing.  The West Chicago filtration headquarters provides long-term manufacturing and manpower synergy with additional operational and office space, reinforcing the company's commitment to sustain its growth.

The balance of AJR Group's business units: AJR Enterprises, AJR Specialty Products, and AJR Custom Foam will continue their operations at the St. Charles facility.

We are confident that the combined organization will create more value for our customers and partners and help us achieve our goal of becoming the preeminent provider of filtration products in the industry.
