The Fieldpiece SMAN4 is a 4-port, wireless digital manifold with a large 3/8" port for faster evacuations and recovery. With four ports and a built-in vacuum gauge, HVACR professionals can now evacuate a system, pull a vacuum, add refrigerant and dial in the charge at one time, without having to hook and unhook any hoses.

To make things even easier, the Fieldpiece SMAN 4 wirelessly receives live indoor wet bulb and outdoor dry bulb, then automatically calculates real-time target superheat, and displays both the target superheat and actual superheat on the large, backlit display. Plus, the SMAN4 digital manifold displays actual subcooling and superheat simultaneously.

The Fieldpiece SMAN4 manifold also wirelessly sends six measurements (indoor wet bulb, outdoor dry bulb, suction line temperature, suction line pressure, liquid line temperature, and liquid line pressure) to the Fieldpiece HVAC Guide System Analyzer, model HG3. The HG3 then combines the SMAN4 wireless measurements with wireless airflow measurements for full system analysis - in real-time.

The Fieldpiece SMAN4 digital manifold can both send and receive wireless measurements so HVACR professionals get a live view of the system and how it's operating. Measurements are updated in real-time while conditions are changing, and while adjustments are being made. So technicians know their work is the most accurate it can be.
