What stokes vacuum does

Stokes Vacuum manufactures heavy-duty industrial vacuum pumps and boosters under four product families: the Microvac 212-612J Series rotary piston pumps (oil-sealed, sub-500 RPM design with over 80 years of proven performance), the Microvane 14-52 Series rotary vane pumps (reintroduced in August 2025 with 52 dB(A) operation and up to 8,000 hours maintenance-free operation), the 212DRY-412DRY dry screw pumps (oil-free vacuum for heat treatment and metallurgy), and 6-inch mechanical booster pumps configurable for vertical or horizontal gas flow. The company sells to industrial customers in heat treatment, aerospace, metallurgy, chemical processing, pharmaceuticals, automotive, electronic manufacturing, food processing, and plastics, addressing applications such as vacuum annealing, brazing, sintering, melting, freeze drying, leak testing, and thin film deposition.

The business operates through two interlocking revenue streams: hardware sales (new pumps, genuine spare parts, V-Lube specialty oils, and certified pre-owned units via the Edwards Webshop) and professional services (factory overhaul, service exchange, certified pre-owned remanufactured pumps, and field service delivered by factory-trained engineers). Pricing is quote-based with no public disclosure, and go-to-market combines direct enterprise field sales with the broader Edwards Limited (Atlas Copco group) global sales and service network. The US operation is headquartered in Sanborn, NY, with service centers in Glenwillow, Ohio and City of Industry, California, plus a new Genesee County, NY facility expected to open by end of 2025; the Asia-Pacific headquarters is in Shanghai, China. Stokes has been an Edwards Limited brand since 2001, following prior ownership by EIS Group (1987), TI Group (1997), and Smith Group (1999).

Revenue model

1. Industrial Vacuum Pump Sales: Stokes Vacuum generates revenue through the sale of heavy-duty industrial vacuum pumps and boosters including Microvac rotary piston pumps, Microvane rotary vane pumps, mechanical booster pumps, and dry screw vacuum pumps. Products are sold directly to industrial customers across multiple sectors.
2. Parts and Oil Sales: Revenue from genuine spare parts (metal eccentrics, gaskets, seals, valve deck assemblies, etc.) and V-Lube oils (V Lube F, G, H) sold for pump maintenance. Available through the Edwards Webshop and direct sales.
3. Factory Overhaul Services: Factory-authorized overhaul services that restore pump performance to original or better specifications using genuine Stokes parts, factory procedures, and specialized tooling. Includes 12-month warranty on parts and workmanship.
4. Service Exchange: Exchange program providing remanufactured Stokes vacuum pumps for seamless swap-out, allowing customers to replace current pumps with exchange units while returning originals at convenience. Features 12-month full warranty and fixed pricing.
5. Certified Pre-owned Pumps: Sale of pre-owned, remanufactured Stokes pumps that have been rebuilt to 'as new' standards using OEM components, factory tools, and genuine spare parts. Cost-effective alternative to new products.
6. Field Service: Onsite field service including commissioning, routine maintenance, troubleshooting, and repairs performed by factory-trained technicians. Available globally through service centers.

Broad incumbents

• Edwards Vacuum: Edwards is the parent brand of Stokes Vacuum and one of the largest global vacuum technology providers. While Edwards sells its own product portfolio, Stokes operates as a sub-brand targeting heavy industrial segments — making Edwards both a parent and a partial channel/distribution peer.
• Agilent Technologies (Vacuum Products Division): Agilent's Vacuum Products Division supplies turbomolecular, ion, and dry pumps primarily for analytical instruments, semiconductor, and research applications. While more skewed to high-vacuum/scientific applications, it overlaps with Stokes in thin-film deposition and electronic manufacturing segments.

Direct peers

• Pfeiffer Vacuum: Pfeiffer Vacuum is a leading global manufacturer of vacuum solutions including rotary vane, turbomolecular, and dry pumps. It serves semiconductor, analytics, industrial coating, and R&D markets that overlap materially with Stokes' aerospace, pharmaceutical, and electronic manufacturing segments.
• Busch Vacuum Solutions: Busch is one of the world's largest manufacturers of industrial vacuum pumps, blowers, and compressors. It directly competes with Stokes across rotary vane, rotary claw, and dry vacuum technologies serving heat treatment, metallurgy, chemical processing, and similar industrial end-markets.
• ULVAC: ULVAC is a Japanese manufacturer of vacuum equipment and systems serving semiconductor, flat panel display, electronics, and industrial markets. Its dry pumps, cryopumps, and mechanical boosters overlap with Stokes' product portfolio in electronic manufacturing, metallurgy, and aerospace applications.
• Leybold: Leybold is a heritage European vacuum pump manufacturer (now part of Atlas Copco, making it a sister entity to Stokes via Edwards) competing across rotary vane, dry, and turbomolecular pump categories. It serves overlapping industrial and process vacuum markets including metallurgy, coating, and heat treatment.

Emerging players

• Ebara Corporation: Ebara is a Japanese industrial machinery conglomerate with a vacuum pump business serving semiconductor, flat panel, and industrial applications. Its dry vacuum and turbomolecular pumps compete with Stokes in electronic manufacturing and chemical processing segments, particularly in Asia-Pacific.
• Kashiyama Industries: Kashiyama is a Japanese manufacturer of dry vacuum pumps serving semiconductor, electronics, and industrial markets. It is a more focused competitor in dry vacuum technology, an area where Stokes has expanded with its 212DRY-412DRY dry screw line.
• Anest Iwata: Anest Iwata is a Japanese manufacturer of oil-sealed rotary vane vacuum pumps and compressors, directly competing with Stokes' Microvane line. It serves similar industrial and process vacuum applications with a strong Asia-Pacific presence.

Regional players

• Shimadzu Corporation: Shimadzu is a Japanese analytical and industrial equipment manufacturer with a vacuum technology offering serving scientific instruments, semiconductor, and industrial markets. Its geographic and product overlap with Stokes is partial, primarily in Asia-Pacific.
