3B Filters

What 3B Filters does

3B Filters, Inc. is a privately held, family-owned manufacturer of high-pressure hydraulic and pneumatic filtration products, incorporated in 2001 and operated from a 15,000 sq. ft. facility in Oak Lawn, Illinois shared with its in-house manufacturing arm Demco Products Inc. (founded 1950). The portfolio is organized around three housing configurations — Tee-Type (8100/8500/8500 Coalescing/8600/8700 Series), Inline (8200/83 & 84/88 Series), and Spin-On (89/90 Series) — paired with a broad replacement element catalog spanning cellulose, micro-glass, stainless steel wire mesh, sintered metal, and coalescing media. Technical differentiation centers on operating pressures from 100 PSI up to 40,000 PSI (8600 Series), flows to 70 GPM and 1,200 SCFM, coalescing efficiency up to 99.995% at 0.3 micron, and 30+ in-house CNC machines supporting short lead times and custom COTS modification.

The business model is a hybrid of inside-sales quote-based engineered sales and self-serve e-commerce, with publicly disclosed per-SKU pricing on a transactional storefront (www.3bfiltersstore.com) carrying 10,000+ OEM interchange elements alongside quote-driven enterprise sales for housings and custom filters. Revenue streams include direct hardware sales (Tee-Type, Inline, Spin-On housings and elements priced $22–$815 per SKU on the low end up to premium tiers), OEM aftermarket interchange sales substituting for Parker, Hydac, Pall, Donaldson, Schroeder, Baldwin, Ingersoll Rand, Hycon, Internorman, Dolinger, Marvel, Argo, Norman, and Chase branded filters, custom engineering and modification services, and recurring maintenance kits tied to installed-system service intervals. Customer segments are aerospace, U.S. Department of Defense, oil & gas (upstream/midstream/downstream), alternative fuels (CNG/LNG/propane/hydrogen), and industrial fluid power markets, with products marketed globally under a Made-in-USA, ISO 9001:2015-certified positioning.
