Automatic air vents — Automatic air vents have fiber

matically bleeding the system, and eliminating the need to
manually remove air from the system. When wet, washers
swell and seal the system.
Drip lips (removable drain extension) — Drip lips are
frequently used when valves are added after unit installa-

proper drainage. The drip lip gives positive control of con-

and allow access to the unit for maintenance. Discharge
grilles are double deflection type, aluminum finish or
