1.0 vessel description
Armstrong va / va s Vortex Air Separators eliminate air quickly
and efficiently from heating/cooling systems. Water enters and
exits through unique tangential connections which promote a
low velocity swirling effect 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.
va s models are equipped with a stainless steel strainer.

3 .0 steps & procedure
• Visually inspect the air separator for damage, which may
occur during transit.
• A manual drain can be added to help facilitate purging sedi-
ment from the air separator.
• va s models have a strainer that must be removed and
cleaned after 2 4 hours of operation.
