Armstrong VORTEX User manual

1.0 vessel description
Armstrong va/vas Vortex Air Separators eliminate air quickly
and eciently from heating/cooling systems. Water enters and
exits through unique tangential connections which promote a
low velocity swirling eect in the centre of the unit. Centrifu-
gal force moves the water to the outer edges of the unit and
a vortex is formed. Entrained air migrates to the eye of the
vortex (lower pressure point) and is evacuated at the top of the
separator. The water exits the unit near the bottom of the unit,
bubble free, protecting the system against the noise, corrosion
and damage associated with entrained air.
vas models are equipped with a stainless steel strainer.
