1、Oil Drip Structure: The oil drip structure adopts the form of inter sealing, which makes the oil supply adjustment more stable and reliable, and greatly improves the durability and reliability 2、Oil Supply Adjustment Ring: The oil supply adjustment ring can only rotate one circle, and the oil supply size is basically linear. The oil supply size can be roughly calculated according to the position of the scale ring 3、Drip Nozzle Structure: With a special drip nozzle structure, negative pressure is generated at the drip outlet, and the fogging flow is low 4、Large Oil Cup: The gas can be refueled continuously, the capacity of the oil cup is large, and the fixed bracket can be selected for installation 5、Extend Service Life: The aluminum alloy body is used, which is durable, corrosion resistance and waterproof, and extends the service life
