Air pressure regulators are used to provide a constant outlet of pressure, separately from the inlet pressure or flow. They are most commonly used to reduce the pressure level required for downstream equipment, stabilizing the force applied to cylinders or minimizing pressure variation. https://youtu.be/3DWidmDwyWs Features: The embedded pressure gauge is a standard feature. Ozone resistant rubber material Improved relief sensitivity. Rc (PT), G (PF) or NPT thread option. Port size: M5, 1/8″, 1/4″, 3/8″, 1/2″, 3/4″, 1 Easy to maintain and operate, long service life. AR series air regulator is the same as & nice replacement for SMC type. It is the standard regulator for air treatment units, and also can use with other equipment to regulate the air pressure Specifications: Item Number: AR5000-10 Cup Capacity: Air Nominal Flow Rate(L/Min): 1.5MPa(15.3kgf/cm2) Working Medium: 1.0MPa(10.2kgf/cm2) Proof Pressure: 5~60℃ Maximum Operating Pressure: 0.05~0.85MPa Weight(kg): Aluminum Package Include: 1 x GPH AR5000-10 Air Regulator
