The Atlas STW-750 is a heavy-duty, hot-water spray wash cabinet built for shops that wash engine blocks, transmissions, differentials, and bulky drivetrain components in volume. A 50-gallon tank, 1,000-lb turntable, and 43 GPM water pump work behind an octagonal, full-opening door that exposes more than 55% of the turntable for engine-hoist loading.
Inside the cabinet, 19 adjustable stainless-steel spray nozzles drive hot detergent solution at 28 PSI across the load. The built-in heater holds wash temperature in the 135°F–175°F range, and a 60-minute timer with automatic shut-off lets the mechanic load the cabinet, start the cycle, and step away to the next job. Parts come out hot and dry within seconds of opening the door — no harmful solvents, just hot water and biodegradable detergent.
Overall cabinet height: 78 inches.Footprint: 44 3/8" L × 44 1/8" W.
Construction is heavy-duty 12-gauge steel with a powder-coated exterior. The door is gasket-free, which simplifies long-term maintenance — there's no rubber seal to age, swell, or weep solution. A built-in stainless-steel oil skimmer draws floating oil and grease off the wash solution, extending its working life between change-outs. A parts tree rack and parts basket ship with the cabinet for hanging or batching smaller components alongside whatever's on the turntable.
Power: 220V single-phase service on a 30-amp breaker, with a 3 HP motor driving the wash pump.
Delivery: choose Warehouse Pickup for will-call at no shipping charge, or Ship to My Address to have it freight-delivered — freight cost is included in that price, so there's nothing extra at checkout. Shipping weight is 800 lbs; a receiving dock or forklift is recommended for delivery.

FAQ

How big a part can I wash in the STW-750?
The cabinet interior is 54" tall and 32" wide, with a 30"-diameter turntable rated for 1,000 lb. The octagonal full-opening door exposes more than 55% of the turntable, so engine blocks and transmissions can be loaded directly with an engine hoist.
How hot does the wash water get?
The built-in heater holds the wash solution between 135°F and 175°F. Hot water plus biodegradable detergent does the cleaning — no harmful solvents required.
How long is the wash cycle?
The standard cycle is 60 minutes with a built-in timer and automatic shut-off, so the cabinet can run unattended while the mechanic works the next job.
What electrical service does it need?
220V single-phase on a 30-amp breaker. The 3 HP motor drives the 43 GPM wash pump.
What's the warranty?
1-year limited warranty on parts only.
Can I pick it up instead of paying for freight?
Yes — choose the Warehouse Pickup option at checkout for will-call pickup with no shipping charge. Choose Ship to My Address instead and freight is included in that price, so there's nothing extra at checkout. Shipping weight is 800 lb; a receiving dock or forklift is recommended for delivery.
