Air purity Pneumatic tools have very high requirements for the purity of compressed air. Compressed air should not contain solid impurities, moisture and oil. This is because impurities and moisture can cause wear and corrosion of the internal parts of pneumatic tools, while oil can contaminate electronic equipment.
air pressure Pneumatic tools usually require stable air pressure to ensure their normal operation. Generally speaking, the working pressure range of pneumatic tools is between 0.5-0.7 MPa. Too high or too low pressure will affect the performance and life of the tool.
Air flow Different types of pneumatic tools have different requirements for air flow. Usually, the load air consumption of pneumatic tools will be indicated in the parameter table, usually expressed in L/s (liters/second). Make sure the air compressor can provide enough air flow to meet the needs of the tool.
Air dryness Moisture in compressed air can damage pneumatic tools, so a dryer is needed to remove moisture from the air and ensure the dryness of the air.
Production requirements:
High purity oil-free air Many industries have extremely high requirements for the purity of compressed air, especially in the fields of food, beverage and medical equipment. Oil-free air compressors can provide clean compressed air and avoid the impact of oil contamination on product quality.
