Caleffi 551 Series Discal Air Separator-1" NPT Connection

Air separator. Brass body. Stainless steel float guide pin and linkage. Glass reinforced nylon internal element. Max. working pressure: 150 psi. Working temperature range: 32—250°F.

The DISCAL air separator is used to continuously remove the air contained in hydronic circuits of heating and cooling systems. The air discharge capacity is very high. They automatically remove all the air present in the system down to micro-bubble level with low head loss due to the special internal shape of the separator body. Flow direction of the DISCAL air separator is bidirectional; flow in either direction is permitted. DISCAL air separators continuously remove entrained air in hydronic systems with very high separation efficiency. The amount of air removed from a system varies depending on fluid velocity and temperature, for example, at the 4.0 feet per second fluid velocity, all the air artificially introduced into the circuit is eliminated by the DISCAL air separator. Any small amount which remains is then gradually eliminated during normal system operation. In conditions where the fluid velocity is slower or the temperature of the fluid is higher, the amount of air separated is even greater.
