Product Description
The WK-245SV Vacuum Pump is a high-efficiency dual-stage HVAC vacuum pump designed for deep and precise evacuation of air conditioning and refrigeration systems. With a 4.5 CFM flow rate, it offers an ideal balance between performance and portability for professional servicing tasks.
Its dual-stage design enables the pump to achieve a deep vacuum level of 15 microns, making it suitable for modern HVAC systems where complete moisture and air removal is critical. The built-in solenoid valve prevents oil backflow, while the high-precision vacuum gauge allows accurate monitoring during operation.
Featuring a forced oil circulation system, durable copper motor, and oil mist filter, the WK-245SV ensures reliable, clean, and long-lasting performance for both field and workshop use.
