Air Compressor Pressure Regulator 0.4-25MPa Oxygen Gas Pressure Reducer Air Flow Regulator Gauge Meter Feature: 1. High quality copper valve body, stable pressure regulation, safe and reliable. 2. The pressure regulator converts the high pressure gas into the low pressure gas, and keeps the outlet gas pressure and flow stable. 3. It can reduce, display and stabilize the pressure; when the inlet pressure and outlet flow change, it can ensure the stability of the outlet pressure. 4. The structure is compact. The pressure gauge and high pressure gauge are made of high-quality materials. The overall structure is compact and the sealing is good. 5. It is mainly used in gas welding, agriculture, plant planting, chemical industry, etc. Specification: Material: Copper Weight: 588g / 20.7oz Measurement range: 0.4-25 (MPA) Applicable medium: oxygen Nominal outlet pressure: 0.25 (MPA) Nominal flow: 40 (MFCC 3; / h) Package size: 131 * 107 * 65 mm/5.15*4.21*2.55' Note: 1.
