The ST-C4BM two-stage battery-powered vacuum pump is an efficient tool designed for use in complex refrigeration, air conditioning and heat pump systems where a deep vacuum must be achieved quickly and effectively. With a high capacity of 127 l/min, the ST-C4BM is ideal for working with larger systems with a significant amount of refrigerant. Its robust design, built-in vacuum gauge and two-stage compression technology ensure stable operating parameters and precise control of the evacuation process. The pump retains the mobility characteristic of battery-powered devices, and the combination of high performance with low noise and IP54 resistance makes it a particularly practical choice for HVAC-R technicians who expect high power and reliability in field conditions.

Main advantages:

• High performance – ideal for larger refrigeration and air conditioning systems
• Versatile compatibility – supports HFC, HFO and A2L refrigerants in line with current industry requirements
• 18V 9Ah battery power supply – freedom to work without mains access and full mobility in the field
• Built-in vacuum gauge – real-time monitoring of the vacuum process in three units (inHg / psi / mbar)
• Two-stage compression technology – quickly achieves a deep vacuum of 2 Pa
• Built-in solenoid valve – automatically shuts off the flow when the power is turned off.
