What Miller Leaman does

Miller Leaman, Inc. is a privately held US manufacturer of industrial water filtration equipment, founded in 1991 and headquartered in a 52,000 sq ft facility in Daytona Beach, Florida. The company designs, fabricates, and sells a broad portfolio of filtration products organized around three core technology platforms: the patented Thompson Strainer series of stainless-steel conical screen strainers (including marine SeaStrainer, duplex, high-temp/pressure, pump skid, and rinse-nozzle variants), the Turbo-Disc automatic self-cleaning disc filtration systems, and the TowerGuard side-stream sand media filters, supplemented by Helix manual disc and screen filters, Ultra-Pure UF and RO membrane systems, and the Maxim programmable backwash controller.

The company serves an enterprise customer base across at least eleven verticals, including industrial manufacturing, HVAC, marine (luxury yachts through US Coast Guard, US Navy, and Canadian Navy vessels), wastewater/reuse, agriculture, food processing, liquid fertilizer, turf, plastics, power generation, and the more recently added hemp/CBD segment. Named customers and specifiers include Continental Automotive Systems, Frito-Lay (via O'Brien Equipment), Lee County HealthPark, North River Boats, Trane, Johnson Controls, the US Army, US Army Corps of Engineers, Hershey, and Duke Energy. Products are sold on a custom, quote-based pricing model, reflecting significant variation in materials (Type 304, 316, CuNi alloys), pressure ratings, flow capacities, and connection types.

The go-to-market is sales-led, supported by an in-house application engineering team that consults on system design, complemented by a global manufacturer-representative network, OEM integration (e.g., North River Boats), and active participation in industry trade shows such as IBEX, AWT, Pacific Marine Expo, the International Workboat Show, AHR Expo, NPE, and METS Amsterdam. Revenue is generated primarily through one-time hardware sales of standard and custom-engineered filtration systems, with some multi-year service relationships implicit in the long-life, mission-critical nature of military and process-industry installations.

Product overview

Miller Leaman is a water filtration solutions company offering a comprehensive portfolio of filtration technologies. Their product portfolio centers around three main proprietary technologies: (1) the patented Thompson Strainer series (conical stainless steel screen strainers with hybrid manual operation), (2) the Turbo-Disc automatic self-cleaning disc filtration systems, and (3) the TowerGuard side-stream sand media filters. Supporting these core lines are the Helix manual disc and screen filters, Ultra-Pure UF and RO membrane systems, and the Maxim Controller for system automation. The Thompson series includes standard strainers, pump skids, rinse nozzle variants, swing bolt lids, high-temp/pressure models, and duplex configurations, with corresponding marine SeaStrainer and basket strainer variants. All products are available with the proprietary Maxim backwash controller for automated operation.
