1. There is a safety valve on the end cap of the air compressor oil tank. When the air pressure in the oil tank reaches 1.1 times of the set value, the safety valve automatically opens, and some air is released to reduce the air pressure in the oil tank. The method of checking the safety valve is to gently pull the bleeder lever on the safety valve when the compressor is fully loaded. If the safety valve can vent outward, it is considered normal.
2. A pressure gauge is installed on the oil tank, and the pressure before the filter is detected. The bottom of the oil tank is equipped with a drain valve. The drain valve should be opened periodically to drain the water and dirt deposited on the bottom of the oil tank.
3. There is a transparent oil level mirror next to the oil tank to show the level of the oil level in the oil tank. The correct oil level is when the air compressor is working normally, the oil level is in the middle position of the upper and lower sides. If it is too high, it will run away. Too low will affect the safety of the whole machine.
4. Oil tanks are produced by professional manufacturers who must have manufacturing qualifications for pressure vessels. Each oil tank has a unique number and certificate.
