The stability of silent oil-free scroll air compressor is similar to that of screw machine, with stable exhaust and low failure rate. But isn't it possible to replace the screw machine at a lower price without losing its quality? Actually, it is not. The principle of scroll air compressor limits that it can only use small models (15KW and below).
Screw machines can only be used if they are higher, so it is a very good choice to replace piston machines or screw machines in small machines. If you want to buy it, you can find Shenzhen Cisco. I bought one from them last time, and the price was quite real.
