The purpose of a vacuum pump is to remove moisture and air from an A/C-R system. Modern systems are built tighter and charges are more critical. That means these systems have a greater sensitivity to moisture and other contaminants, making thorough evacuation more important than ever before. Moisture in a refrigeration system, directly or indirectly, is the cause of most problems and complaints. First, moisture can cause freeze-up in a system. Moisture is picked up by the refrigerant and transported through the refrigerant line in a fine mist, with ice crystals forming at the point of expansion. “Freeze Up†is not the only problem caused by moisture. It can also result in corrosion, the effects of which are not apparent until the real damage has occurred. Moisture alone is bad enough, but combined with refrigerants containing chlorine, hydrochloric acids can form. These greatly increase the corrosion of metals. Also, refrigerant oil rapidly absorbs moisture. Water formed acids combine with the refrigerant, forming a closely bonded mixture of fine globules. The effect is called sludging and it greatly reduces the lubricating ability of the oil. A vacuum pump removes troublesome moisture by lowering the pressure within the system and vaporizing (or boiling off) the moisture, then exhausting it along with air. * Offset Rotary Vanes – Our proven design creates the deep vacuum conditions needed for a thorough evacuation * Gas Ballast feature – helps keep the pump oil clean by reducing condensation of moisture * Iso-Valve – isolates pump from the system with just a 1/4 turn, making it simple to measure rate of rise * Integral Check Valve – prevents pump oil from being sucked into the system if a power loss occurs * Die-Cast Aluminum housing – lightweight but durable * Molded Base – Durable polycarbonate base improves pump balance and minimizes vibration Free Air Displacement 1.2 CFM (60 Hz) ACME Oil Capacity 5 oz. (148 ml) Motor Size 1/8 HP Voltage 110-115V 50-60 Hz Robinair Vacuum Pumps are engineered specifically to meet your A/C maintenance needs and to give you trouble-free operation.
