About this item

Product Features:

• Equipped with an R32 explosion-proof function; ideal for repairing air conditioning systems; compatible with a variety of A1 refrigerants including R134A, R410A, R12, R22, and R502, as well as A1 and A2L refrigerants
• Features a solenoid valve which effectively prevents oil backflow, thus protecting the equipment
• Flow Rate 2.5-7 CFM, 3/4HP; ultimate vacuum: 10-15 Pa

Inlet and Exhaust:

• Inlet: 1/4SAE or 7/16-20UNF
  • Recommended hose: 8 mm ID hose with 1/4 SAE or 7/16-20 UNF fitting for optimal sealing.
  • An 8 mm ID hose without fitting can be used, but the seal may not be as tight.
• Exhaust (filter) port size: 24mm
  • If the gas reacts with pump oil (e.g., water vapor), use a trap before the inlet.
  • If the gas is harmless to oil but cannot be vented to air, connect an absorber at the exhaust and direct it to a fume hood. Exhaust port fits 24mm ID hose.

Additional Information:

• Note that "R32 Explosion-Proof" refers to the pumps ability to operate with air that has a flammability level not exceeding that of R32 refrigerant
• Recommended Oil Type: Vacuum pump oil with a viscosity of 100
• Widely used in various applications such as laboratory experiments, research, vacuum packaging, refrigeration maintenance, wine degassing, and thermoplastic molding
• ASIN: B0CWNVMW86, B0CWNXKWBM
