Application
The P70AA-400 is designed for use in commercial and residential refrigeration and air conditioning systems utilizing R410A refrigerant. Its broad pressure range of 100 to 470 PSI makes it well-suited for the higher operating pressures characteristic of R410A systems. The 36″ capillary provides installation flexibility, allowing the control to be remotely mounted away from the sensing point.
