AIR SEPARATORS
Air separaSion eEkBienBX
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, As
illustrated on the graph below, 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.
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.

ConsSrTBSion deSails
The air separator uses the combined action of several physical principles.
The active part consists of an assembly of concentric mesh surfaces (1).
These elements create the whirling movement required to facilitate the
release of microbubbles and their adhesion to these surfaces. The bubbles,
fusing with each other, increase in size until the hydrostatic thrust overcomes
the adhesion force to the mesh. They rise towards the top of the unit from
which they are released through a float-operated automatic air vent, with
stainless steel float guide pin (3) which keeps the float from binding.
