What’s in the box?

Upon opening this package, you will find what you asked for: one Silentaire Sil-Air 50-15 Silent Running Airbrush Compressor that features a rather large 4-gallon tank Additionally, an oil bottle type ROLOIL – SINCOM/32E, instruction manual, and a tank certificate.

A large unit with a convenient handle for moving around if needed.

The dimensions of this silent running airbrush compressor are 15.7″ x 15.7″ x 23.6″, while the total weight is 60 pounds (around 27 kilograms). Despite the weight, the unit is easily portable as it comes with a set of wheels.

The Silentaire Sil-Air 50-15 Silent Running Airbrush Compressor is a completely automatic unit which is an ideal feature that prevents overheating of the unit. When the pressure grows within the tank, the compressor warms up and then the automatic switch stops the motor. When it cools down and the pressure drops, it automatically starts up the motor again.

A safety valve is a nice touch too, as it additionally protects the compressor from overheating.

Another great thing is the air intake filter that keeps the dust, water and other airborne contaminants out.

There’s more

It is operated by a 1/2 HP engine at the voltage of 110Volt/60Hz. The built-in tank is rather large and is 4 gallons. The tank itself is internally painted in order to prevent rust from forming. No need to mention that the tank has it’s on regulated pressure gauge. You can regulate pressure easily with the regulator and don’t worry about moist building up as the compressor has a moisture trap.

It gets better

The compressor is made to operate three airbrushes simultaneously. The operating pressure is between 84 and 114 PSI, 114 being the maximum pressure. The output airflow is 2.15 CFM while the noise level it produces is around 40 decibels. Now, that’s what I call quiet!

Oh yes, the product warranty is 12 months but be sure it will last much longer.

User Review

I know some people that use this model as their one and only primary compressor for every possible application. They saved up the money and bought it, without any hesitation. I didn’t get why would they pay so much for a compressor. Then, I got a chance to use this unit on a job site for two months. Now, I can say that I fully understand.

This Silentaire model is really something. The noisy Italians have managed to make something so quiet. Not knowing the features of the model, I measured the noise level which was at around 40 decibels. To give you the full impression, that’s like the noise your computer makes when turned on. So, a slight humming that you don’t even notice. This is the first thing that amazed me. I worked in peace and quiet for two whole months. The job was demanding and long, around 9 – 11 hours of work a day, but this beauty took it like a champ!


There were no air leaks. And I checked regularly. The unit didn’t overheat not once. I think this is due to the safety valve. But then again, the motor is cast iron made, which helps the heat to spread evenly. The compressor runs long and shuts off occasionally. It doesn’t walk around the room while on and it is easy to transport. It was a bit strange to use it at first, since I am not used to using fully automatic compressors. After few hours, I couldn’t imagine working with any other kind than this.

This is model is something really special. Fully automatic, with a large tank and everything that makes a compressor your essential tool. I couldn’t describe how powerful and silent it is, you have to see it for yourself. I highly recommended it!

I would have bought for myself but unfortunately my budget is a bit low at the moment. But, the first chance I get, this baby is mine!

To conclude

Reliable, powerful, silent – what more can you need? The Silentaire Sil-Air 50-15 Silent Running Airbrush Compressor is a purchase made once in a lifetime and surely won’t make you regret your choice. Sure, it’s expensive but have in mind it will last. If you have the money, don’t think twice!
