Voltage/Frequency: 110V/60Hz. It maintains air conditioning systems by effectively removing moisture before refilling the refrigerant, perfect for those who want to self-diagnose or recharge their AC systems. HVAC DIGITAL VACUUM GAUGE: Digital vacuum gauge can measure the real-time pressure during vacuuming of the refrigeration system, suitable for dynamic monitoring of vacuum pressure changes in HVAC and heat pump systems. It can be used in conjunction with a vacuum pump to measure the real-time pressure during vacuuming, quickly and accurately judge the degree of dehumidification and impurity removal, and detection the vacuum system and refrigeration systemin real time. STABLE OPERATION - Our AC vacuum pump made of reinforced aluminum alloy casing, it ensures effective heat dissipation and is corrosion-resistant and durable. Its air intake filter and trap effectively prevent oil backflow and separate exhaust gas from the oil mist filter to maintain optimal performance. PARAMETERS: Maximum overload pressure of vacuum gauge: 72 psi/0.5 Mpa; Accuracy: 0.1-1000 Pa (digital plus or minus 5%); Resolution: 0.01(?10 Pa); Operating temperature: -23-122 ?; Connection:7/16"-20 UNF(1/4" SAE). Digital HVAC vacuum gauge uses pirani vacuum sensor, which can respond quickly and accurately measure micro-pressure changes in vacuum. WIDE APPLICATION - Rogvoc AC vacuum pump are widely used for automotive refrigeration maintenance and HVAC repair, an effective tool for removing contaminants from air conditioning and refrigeration systems. Widely used in automotive HVAC maintenance, vacuum packaging, vacuum forming, medical machinery, printing machinery and other fields. Applicable to R12 R22 R134a R410a and more.
