The hardware is identical — same four 1680W motors, same 200L tank, same 560 L/min output. The only difference is the power supply: the 240A runs on 220V single-phase, while the 240B requires 380V three-phase. Choose by what your building already has; the two models cannot be field-converted.

At 6720W, a single-phase feed draws heavy current on one line, while a three-phase feed splits it across three — lower current per conductor, less heat in cables and contacts, smoother motor starting, and better compatibility with industrial distribution boards and generators.

A 380V three-phase circuit with a dedicated motor-rated breaker sized by your electrician (typically around 16–20A per phase for this load), correct earth bonding, and standard three-phase cabling to the machine's terminal box. No soft-start cabinet or star-delta starter is required.

As a rule of thumb: a dental chair consumes roughly 50–70 L/min at peak. This unit comfortably serves eight or more chairs, a full laboratory floor with multiple instruments, or light pneumatic machinery such as spray guns, nailers and small actuators running continuously.

The remaining three motors keep producing about 75% of nominal flow — usually enough to run the facility at reduced margin while a replacement pump is shipped. Each motor-pump head is an independent cassette: swapping one is a bolts-and-connectors job, not a full machine teardown.

Export orders leave the factory in a plywood crate with the machine bolted to a pallet. On site, the four casters and side handles let two people roll it into position; once placed, the unit should be leveled and, for permanent installations, anchored or chocked.

There is no oil to check, top up, or dispose of, and no oil-lubricated parts to contaminate downstream air. Routine care reduces to draining condensate from the tank, cleaning intake filters, and an occasional visual inspection — maintenance your existing staff can handle.

Yes. Colors, tank decals, control panel layout, packaging design and plug types can all be customized
