Extwin Dirt & Air Separator
Please check specifications below if product has options
Extwin, combined microbubble and dirt separator for
heating and cooling systems for sealed system circuits.
Suitable for use with water and water/glycol mixture to
a maximum of 40% concentration.
The Extwin offers the combined functions of the specialist
individual air separator and a dirt/sludge component in a
single, compact fitting. A far more cost-effective solution
than using both the individual components.
The air separator is for removing circulating free air and
gas bubbles with high efficiency from the system flow.
Permanent evacuation by way of integrated automatic
air vent with high venting capacity. Facilitating hydraulic
balancing after filling operations.
The dirt separator is for the removal of dirt particles
up to a size of 0.5mm out of the liquid flow by way of
a specifically designated insert. The Extwin is fitted with
a ¾“ service/drain valve located at the bottom of the
unit for easy removal of the collected dirt/sludge,
no additional shut-off valves or bypass lines required.
The collection area can be easily emptied at regular
intervals using a drain ball valve while the system
remains in operation. The flanged collection chamber
can be removed for inspection.
