Silent compressor we sell in three brands: Euro-Tec, Hansa and Sil Air. They all come from the same manufacturer Werther Italy the number one company for silent compressors. Technically the models are almost equal to each other just the design and color is different. That is why we've got all three brands on stock. All compressors are silent (like a refrigerator) They do have a automatic shut of, superb pressure regulator / moisture separator. And are giving always clean air so beside the use for airbrush also perfect to clean your computer, camera, and for other technical work. Most engines from cheaper brands are welded, in case of trouble you can not repair them. The engines from Werther can be opened and serviced even if they are 20-30 years old. Airbrush Services Almere has almost all the parts for the Werther compressors on stock even if it is 20 years old or older. For us the reason only to sell the Werther compressors. Well maintained a life-time buy! On the silent compressors you have a full 2 year warranty.
