Hubbell Industrial Controls 69WB3 Pressure Switch

The Hubbell Industrial Controls 69WB3 is a pressure switch that is essential for maintaining consistent air pressure in a variety of HVAC systems. It works as an automated on/off switch for your air compressor, responding to variations in air pressure. When the pressure reaches a predetermined level, the switch opens, turning down the compressor to avoid overpressurization. In contrast, if the pressure goes below the set point, the switch closes, restarting the compressor to maintain enough pressure. The Hubbell Industrial Controls 69WB3 automatic pressure control mechanism is required for the effective and safe functioning of various HVAC equipment, such as air conditioners, refrigeration units, and air handlers.
