What Duraflow Industries does

Duraflow Industries, Inc. is a privately held, Ohio-based manufacturer of air filtration products founded in 1979 and operating from a single facility in Wakeman, near Cleveland. The company designs and produces aluminum mesh filters, aluminum-carbon combination filters, activated carbon filters, foam filters and rolls, electrostatic filters, HVAC aluminum panels, and industrial/heavy-duty air filters, along with custom filtration solutions including HEPA/ULPA grades. Core technical capabilities include in-house engineering, custom carbon blending, precision die-cutting to 5/1000th-inch tolerances, rapid prototyping (5–10 business days for runs under 1,000 pieces), and airflow testing through independent laboratories.

The company operates a hybrid go-to-market combining direct e-commerce (duraflowindustries.com), consultative enterprise sales for OEM and custom solutions, and a channel-partner program serving industrial supply houses, wholesale distributors, and maintenance supply companies with private labeling, drop shipment, and tiered rebate programs. Revenue derives from three streams: standard product sales through the online storefront, custom OEM filtration contracts (multi-year relationships, quote-based pricing), and B2B supply to distributors with volume-based pricing. Customer segments span residential replacement buyers, commercial and industrial facilities, OEMs in medical, defense, electronics, and power generation, and wholesale/industrial supply distributors. Reported operational metrics include 3-day standard lead times, next-day custom fabrication capability, and a documented 50% cost advantage versus a leading specialty filter competitor on a complex electronics bid. The company is led by President Mark Sliman and employs between 11 and 50 people.
