This compact oil-free compressor pairs a 1/6 HP motor with a built-in cool-down fan, so it keeps spraying through long sessions instead of overheating. The pressure switch starts the pump automatically at 3 bar (43 PSI) and stops it at 4 bar (58 PSI), keeping air ready while saving wear.

Air flows at 20–23 L/min through the adjustable regulator, and the in-line water trap strips moisture before it reaches your airbrush, protecting finish quality. A front gauge shows working pressure at a glance, and the 1/8″ BSP outlet fits most hobby hoses and airbrushes, with other fitting sizes available.

Weighing just 4.1 kg in a 255 x 135 x 205 mm body, it lifts by metal handle from bench to booth or client visit, while suction rubber feet anchor it firmly against vibration. CE, GS, ETL, and RoHS certified, running on AC110–220 V 50/60 Hz worldwide.

FAQ

1. Question: Is this compressor oil-free, and does it need maintenance?

Answer: Yes, it is fully oil-free: no oil to fill, no oil mist to contaminate your paint, and no break-in procedure. The motor is maintenance-free for normal studio use; the only routine care is draining the water trap when it collects moisture and wiping dust off the cooling fan intake occasionally. That simplicity makes it a fit for hobby benches, nail stations, and mobile work alike.

2. Question: What does the auto start/stop function do, and can I leave it switched on?

Answer: You can. The pressure switch monitors the pump: when line pressure falls to 3 bar (43 PSI) the motor starts by itself, and at 4 bar (58 PSI) it stops. Meanwhile the built-in fan cools the pump housing, so unlike basic diaphragm pumps it tolerates continuous spraying without thermal shutdowns. You just spray; the compressor manages its own duty cycle.

3. Question: Which airbrushes and hoses connect to it?

Answer: The outlet is a standard 1/8″ BSP thread, which fits the majority of hobby airbrushes and hoses directly; other fitting sizes are available if your setup uses a different thread. With 20–23 L/min of airflow and an adjustable regulator, it comfortably feeds one airbrush for model painting, nail art, tattoo work, or cake decorating. The front gauge lets you dial in exact pressure for fine detail or broader coverage.
