Description
The Johnson Controls P233A-4-PAC International Differential Air Pressure Switch is equipment which are widely used in HVAC systems to measure and modulate air pressure differentials. Especially often in commercial and industrial applications this kind of differential air pressure switch is used if an exact air pressure regulation is required. This switch is versatile and long-lasting as well, and the temperature is a low of -20°F and a high of 150°F and pressure is a 1/4 in. NPT connection. It can also withstand many episodes of weathering. The P233A-4-PAC helps in maintaining the pressure variations in the range thus helping to prevent damages to the HVAC equipments and also improves the efficiency of the equipment.
