Hubbell Industrial Controls 69WA4 Pressureswitch Airwtr 30-50#

The Hubbell Industrial Controls 69WA4 Pressure Switch is a dependable and adaptable device for maintaining constant air or water pressure in a variety of HVAC systems. It detects changes in pressure by using an internal diaphragm and pressure settings that may be adjusted. Pumps, compressors, and chillers that are connected to the switch are activated when the pressure drops below the setpoint. On the other hand, the switch deactivates the device when pressure increases above the setpoint. By maintaining ideal pressure levels, this device guards against over- or under-pressurization, which can damage equipment and reduce system performance. The 69WA4 Pressure Switch is useful in humidifiers, dehumidifiers, pumps, chillers, cooling towers, and air compressors. It lowers energy expenditures by automatically controlling pressure, which increases system efficiency.
