Air separator construction
DISCAL
®
air separators are constructed to allow maintenance and cleaning
operations to be carried out without having to remove the separator body
from the pipe work. All DISCAL air separators have a bottom connection
drain valve. All internal air release control components are fully accessible.
The automatic air release valve, located at the top of the separator, has a
long chamber for the movement of the oat. This feature prevents any debris
present in the water from reaching the sealing seat.
Flanged models include a side drain vent to release large amounts of air
when lling the system and to remove any debris present above the water
level.
