DISCALAIR automatic air vents release air that forms in the hydraulic circuits of heating and air conditioning systems, with pressures to 150 psi. The venting air discharge capacity is very high capable of expelling over 4 standard cubic feet per minute (SCFM). The circulation of fully de-aerated water or glycol-water mediums enables the equipment to operate under optimum conditions, free from noise, corrosion, localized overheating or mechanical damage.
How the Caleffi 551028A Works?
The accumulation of air bubbles in the main vent body causes the float to drop so that the air release valve opens. This action, and therefore correct valve operation, is ensured as long as the water pressure remains under the maximum discharge pressure.
