This vacuum pump is designed for professional use in air conditioning systems. The pump creates a vacuum, which makes the subsequent filling of the air conditioning system with refrigerant possible. The pump features an aluminium housing and a practical oil sight glass, which allows you to check the oil level at any time. It also has an integrated handle for easy transport. The included 2-way manifold gauge set is suitable for filling and inspecting air conditioning systems by providing system pressure readings. It is suitable for use on all car A/Cs, as well as commercial and domestic A/C refrigeration systems. The colour-coded gauges are quick, clear and easy to read. The gauges are encased in a protective bumper to prevent damage. You can use the integrated steel hook to quickly and easily suspend the gauges. The manifold gauge set has a durable construction.
