This complete refrigerant device set includes the vacuum pump and the 2-way pressure gauge set in a molded housing. This vacuum pump is designed for professional use in refrigeration and air conditioning systems. The pump creates a vacuum that allows the air conditioning system to be subsequently filled with refrigerant. Due to its technical characteristics, the pump is suitable for repairs of refrigeration equipment, printing machines, medical equipment, vacuum packaging equipment, hot forming and other extraction operations. The pump has an aluminum housing and a handy oil sight glass that allows you to check the oil level at any time. It also has an integrated handle for easy transport. This 2-way pressure gauge set is suitable for filling and testing air conditioners by providing system pressure readings. It is suitable for all air conditioning systems as well as commercial and residential refrigeration systems. The color-coded displays are fast, clear, and easy to read. The displays are provided with a shock protection to prevent damage. The integrated steel hook allows you to hang the gauges quickly and easily. The pressure gauge set has a durable construction and comes in a blow-molded carry bag for easy transport and storage.
