Shanghai MAC is a leading diaphragm compressor supplier.
A diaphragm compressor is a special type of positive displacement compressor. Its core principle is to completely isolate the compressed gas from the hydraulic drive system through a flexible metal diaphragm, thereby achieving oil-free, pollution-free, and zero-leakage gas compression.The gas does not come into contact with the lubricating oil, ensuring extremely high gas purity, while also possessing excellent sealing properties to prevent media leakage.
