Streamline deep-vacuum evacuation with the Robinair 15600 CoolTech 6 CFM Two-Stage Vacuum Pump (SKU: ROB15600). Engineered for professional HVAC service technicians, fleet maintenance specialists, and commercial auto repair facilities, this industrial-grade robinair cooltech pump combines a 6 CFM displacement rate with a dual-stage rotary vane design to reach ultralow vacuum levels in less time.
Built with heavy-duty cast aluminum housing and a high-torque motor, the Robinair 15600 features a gas ballast feature that purges moist air from the system before it can condense in the oil reservoir. An integrated intake isolation valve allows technicians to isolate the pump from the system during decay testing without losing vacuum pressure. Coupled with forced-feed lubrication and a clear sight glass, this reliable 6 cfm vacuum pump guarantees long-term durability when used with premium robinair vacuum pump oil.
