All three share the same 1450W pump platform, 8 bar ceiling and 220V supply. The SP-30S uses one head with a 25L tank (138 L/min), the SP-50S pairs two heads with 50L (276 L/min), and the SP-90S runs three heads against a 90L reservoir for 384 L/min plus two-thirds flow redundancy. Choose by the number of simultaneous air tools you run and how long the machine works per hour.

Yes. Total draw is about 4350W at 220V/50Hz — roughly 20A, which a standard 25A or 32A workshop circuit handles comfortably. No three-phase supply, converter or soft-start kit is required.

Isolate the affected head at its connector and keep working on the remaining two — you retain about two-thirds of rated displacement. The heads are modular, so a replacement bolts on without touching the other two circuits.

Continuous spraying and powder-coating prep, dual-bay tyre inflation, car detailing with high-flow water guns, framing and brad nailers, and light industrial blowing stations. It is the right pick once a two-head machine can no longer keep pace with duty cycle.

No lubrication service is ever needed on the pump heads. The only routine tasks are draining tank condensate weekly, brushing dust off the fan grilles, and checking the braided hoses and fittings periodically.

Units go out in reinforced export cartons on pallets, tank empty and valve closed. Common service items — pump heads, pressure switch, check valve, solenoid unloader — are held in stock and can be shipped together with future orders.
