1、MORE STABLE AND RELIABLE: The oil drip structure adopts the form of gap seal. The oil adjustment is more stable and reliable, and the gas can be refueled without stopping air 2、ROUGHLY CALCULATED AMOUNT ACCORDING SCALE RING: The oil supply adjustment ring only rotates once, and the oil supply size is basically star shaped. The oil supply amount can be roughly calculated according to the position of the scale ring 3、LOW FOGGING FLOW: The special drip nozzle structure produces negative pressure at the drip outlet and low fogging flow 4、HIGH REPEAT ACCURACY: Air filter regulator lubricator combo bring stable pressure regulation, high repeat accuracy, very reliable 5、FAST AND RELIABLE FIXED CONNECTION: Compressed air filter provide fast and reliable fixed connection, have high installation accuracy 6、THREE DRAINAGE TYPES: There are three types of drainage, that is manual, differential pressure and automatic drainage for you to choose from, more flexible 7、EFFICIENT REMOVAL OF WATER AND SOLID PARTICLES: With efficient removal of water and solid particles, very practical, you can use with confidence
