Peterson P30B Spraywasher

The Peterson P30B is an industrial-grade spray washer designed for cleaning, degreasing, and preparing metal components and castings — such as engine blocks, cylinder heads, housings, transmission cases, and other machine shop parts. This type of parts washer uses high-pressure aqueous spray and detergent (or appropriate cleaning solution) to remove oil, grease, machining grime, coolant residue, carbon, and other contaminants that standard wash methods may not eliminate. Converting to a used unit, the P30B offers shops a cost-effective way to add professional cleaning capability without the expense of a new washer.

 

Using a parts washer like the P30B can dramatically reduce labor, increase throughput, and improve consistency — key advantages for engine rebuilders, remanufacturers, diesel shops, or any machine shop dealing with greasy, dirty metal parts before machining or reassembly. A properly functioning washer also helps manage waste, control mess, and deliver cleaner workpieces that are ready for machining, inspection, or assembly.

Key Features

  • High-Pressure Spray Cleaning in Enclosed Washer Chamber — Delivers concentrated spray jets to parts, reaching crevices, internal passages, and complex cast shapes for thorough cleaning. This ensures oil, grease, coolant, carbon, and machining residues are removed efficiently.
  • Aqueous (Water-Based) Cleaning System — Compared with solvent-soak or manual degreasing, aqueous cleaning reduces hazardous exposure, simplifies waste disposal, and is often more environmentally friendly when handled correctly.
  • Large Tank/Chamber Capacity — Suitable for engine components and heavier castings (heads, blocks, housings), making the washer practical for medium to heavy-duty parts cleaning typical in engine rebuilding or remanufacturing shops.
  • Labor and Time Saving — Automates the cleaning process, reducing manual scrubbing and repetitive labor. Ideal for shops with high part turnover or frequent rebuild/prep workloads.
  • Labor and Time Saving — Automates the cleaning process, reducing manual scrubbing and repetitive labor. Ideal for shops with high part turnover or frequent rebuild/prep workloads.
  • Improved Shop Cleanliness & Safety — Containing the wash process in a cabinet or enclosed washer reduces splash, overspray, and contaminants — contributing to a safer, cleaner work environment.
  • Versatile for Different Part Types — Works for automotive, diesel, industrial, and general machine-shop components. Whether cleaning small housings or large blocks, the washer’s flexibility makes it a handy all-purpose cleaning tool.
  • Cost-Effective Upgrade (Used Unit) — For shops on a budget or expanding capacity, a used P30B provides many of the capabilities of a new washer at a lower investment, while still delivering industrial-grade cleaning performance.

Built on Real Engine-Rebuilding Experience

Decades before today’s engine shops trusted our equipment, Tony was already deep in the craft — rebuilding motors, machining blocks, and pushing for better precision.

A local newspaper once featured him as a standout young machinist, noting his drive, attention to detail, and obsession with doing things the right way. That same passion would eventually shape our company’s values.

Today, that commitment lives on in every machine we sell, every customer we support, and every shop we help succeed.
