What Separ Filter does

Separ America LLC, operating as Separ Filter, is the exclusive North and South American distributor (since 1995) for German-engineered fuel water separators manufactured by Willibrord Lösing Filtertechnik, a German filter technology firm founded in 1955. The company is headquartered in Davie, Florida, and has been a wholly owned subsidiary of Crawford United Corporation (OTC: CRAWA) since January 10, 2022. Its portfolio centers on diesel fuel contamination control across power generation, transportation, agriculture, marine, military, and construction/mining end markets, with the SWK-2000 Series (five-stage filtration, 79–2,060 GPH flow rates, 99% free-water and particulate separation), EVO-10 (rotational separation, up to 158 GPH), and LKF Series (coalescence filtration, >95% water separation per ISO/TS 16332) as core product lines, complemented by a Hand Priming Pump and a full replacement-parts ecosystem (elements in 10/30/60 micron ratings, bowls, lids, gaskets, sensors, gauges).

The underlying technology is purely mechanical and stage-based: fuel passes through internal vanes and multiple filter media to physically coalesce and separate water droplets and particulates before they reach the engine, with the SWK-2000 also available in duplex redundant configurations for continuous-operation power applications. All products are described as German-engineered with patented architectures, and the company emphasizes performance metrics (99% separation on the SWK-2000; >95% on the LKF under ISO/TS 16332) as core differentiators. There is no software, telemetry, or digital product surface disclosed; the offering is physical hardware plus technical documentation and comparison tools.

The business model is industrial hardware distribution with a multi-channel go-to-market: (1) direct e-commerce on separfilter.com (BigCommerce-powered) accepting credit card, PayPal, wire transfer, and ACH, with publicly listed unit pricing; (2) phone-based direct sales (+1 954 523-9396) for OEM and aftermarket buyers handling oversized LTL shipments; and (3) an authorized dealer and distributor network spanning the US, Canada, Central America, South America, and the Caribbean. Pricing ranges from small consumables (O-rings at $0.73) to large assemblies (SWK-2000/40 60-micron stainless elements at $3,694.36, duplex assemblies above $3,100), with complete filter assemblies generally between $175 and $2,500+. Revenue is recurring through proprietary replacement elements, creating an installed-base annuity on top of initial system sales. Revenue, headcount specifics, and customer-level financials are not disclosed.

Broad incumbents

• Mann+Hummel: Mann+Hummel is a global filtration manufacturer whose diesel fuel/water separation products compete with Separ across OEM and aftermarket channels, particularly in Europe where Separ's parent is based.
• Cummins Filtration (Fleetguard): Fleetguard is the OEM-aligned diesel filtration brand of Cummins, offered both as factory-fit and aftermarket; it competes with Separ primarily through OEM bundling but overlaps in the same diesel filtration aftermarket.
• Bosch Automotive Aftermarket: Bosch supplies diesel fuel filters and water separators widely used in commercial vehicles and stationary engines, serving as a broad incumbent competitor across multiple Separ end markets.

Direct peers

• Racor (Parker Hannifin): Racor is the dominant diesel fuel water separator brand in heavy-duty, marine, and power generation applications and competes head-to-head with Separ's SWK-2000 and LKF lines for the same fleet and genset customers.
• Donaldson Company: Donaldson manufactures a broad range of diesel fuel filtration assemblies and replacement elements that directly compete with Separ's product line in trucking, agriculture, construction, and power generation end markets.
• Stanadyne: Stanadyne produces diesel fuel filtration and water separation systems aimed at heavy-duty engines, gensets, and agricultural equipment — overlapping directly with Separ's target applications.
• Baldwin Filters: Baldwin manufactures heavy-duty diesel fuel filters and water separators for trucks, ag, construction, and industrial equipment, distributing through an extensive North American aftermarket network comparable to Separ's dealer model.
• WIX Filters: WIX (a Mann+Hummel brand) produces diesel fuel filtration products for light- and heavy-duty applications, overlapping with Separ's LKF and EVO-10 product positioning in trucks, gensets, and light industrial equipment.

Emerging players

• Dorman Products: Dorman is a North American aftermarket parts distributor covering heavy-duty and commercial vehicle categories; while not a direct fuel-separator competitor, it competes for the same dealer relationships and shelf space in the diesel aftermarket channel.

Others

• Caterpillar OEM Filtration: Caterpillar offers proprietary fuel filtration as part of its equipment ecosystem, representing the OEM-integrated approach that competes with aftermarket standalone separators like Separ's SWK-2000 and EVO-10 lines.
