Sandblasting Machine for Parts Cleaning JA-900 - 3/4HP Motor

The sandblaster removes oxidation, rust and accumulated dirt from engine parts before machining. The JA-900 uses aluminum oxide as abrasive, efficiently cleaning components like cylinder heads, blocks, pistons and connecting rods. With capacity for parts up to 27.6x27.6 inches (700x700mm), it eliminates manual cleaning with chemical solvents, ensuring clean and uniform surface for rebuilding processes. It's essential equipment for shops working with old or heavily soiled engines.

The JA-900 accepts parts up to 27.6x27.6 inches (700x700mm) area and 27.6 inches (700mm) internal height, accommodating most automotive cylinder heads and engine blocks. It comes equipped with 3/4HP three-phase 220V electric motor, consuming 20 CFM compressed air through 0.31 inch (8mm) tungsten carbide nozzle. Machine dimensions are 2.3x2.3x5.6 ft (0.7x0.7x1.7m) weighing 287 lb (130kg). It's ideal for professional rebuild shops needing capacity for engine components from compact cars to medium-duty trucks.

Aluminum oxide blasting cleans practically all metallic engine components: cast iron and aluminum cylinder heads, blocks, pistons, connecting rods, crankshafts, flywheels and transmission housings. It removes heavy oxidation, old paint, carbonized oil and combustion deposits. It's especially effective on truck engines, tractors and industrial machinery that sat idle for years. The JA-900 also serves to prepare surfaces before welding or applying special paints on restored parts.

Mechanical blasting with aluminum oxide removes heavier and embedded dirt that chemical solvents cannot handle, especially deep rust and old paint. It's faster for large volumes of parts and leaves no chemical residues. However, chemical cleaning is gentler for delicate parts and better removes oils and greases. The JA-900 complements chemical cleaning, being used first for heavy removal, followed by fine chemical degreasing when needed for perfect finishing.

The process mixes compressed air with aluminum oxide at high velocity through the 0.31 inch (8mm) tungsten carbide nozzle. The part stays inside the closed chamber while operator controls blasting through integrated gloves. The 3/4HP motor aspirates used abrasive and recirculates it, saving material. Aluminum oxide impacts the part surface removing oxidation and dirt through mechanical impact. The entire process is contained, preventing dust dispersion in the shop environment.

Maintenance includes periodic replacement of tungsten carbide nozzle (wears with use), air filter cleaning, chamber seal verification and aluminum oxide replenishment. Electric motor needs bearing lubrication per manual. With proper use and regular maintenance, the JA-900 operates for decades in professional rebuild shops. Manufacturer offers replacement parts and technical support. Service life depends on usage intensity, but it's robust equipment designed for heavy industrial work.
