　　Due to the requirement of the work environment, more and more users choose silent air compressor, how to choose suitable for their own use oil-free air compressor, the author based on rich market experience, recommendations are as follows, hope to help you.

　　1. if the user's equipment requirements for air quality is not high, can choose mute type air compressor oil lubrication. This kind of air compressor refrigerator compressor of air compressor, very quiet voice, generally less than 45 db. Vibration is very small. Oily disadvantage is: air compressor in transit cannot long time inversion, failure rate is higher, due to domestic recycling USES mostly refrigerator compressor of air compressor, so high failure rate. Traffic is low.

　　2. to enter the market in recent years the mute oil free type air compressor, the compressor is swinging piston work form, adopt symmetric on both sides of the middle motor cylinder structure, effectively solves the problems of vibration and displacement is small. This kind of air compressor noise generally under 60 decibels. For user needs high quality gas, suggested that choose such air compressor.
