Description
The Johnson Controls P28PA-4 Differential Pressure Control is an HVAC device used to keep the differential pressures of the systems at desirable levels to increase their efficiency. It has a strong construction and comes in a small form factor of 5.0″ thus making it suitable for use in different HVAC applications. It operates between the pressures of 8 to 70 PSI; thus, is used to control air or gas pressures in ducts, filters, or other essentialHVAC system components. It is designed to operate at a control voltage of 24V and is easily incorporated into control systems to provide reliable and accurate pressure control and measurement.
