Graphite filled PTFE bearings housed in a 100% FRP packing gland.
Viton shaft seals.
100-mil corrosion barrier applied to all internal surfaces.
Optional blade seals for low-leak applications.
Shaft is fully encapsulated between two blade halves.
Typical Applications
Gooseneck Intakes:
The ECS damper opens to allow fresh air to flow into a contained area where foul air is being drawn.
The damper shuts when air flow is neutralized.
Fan Outlets/Inlets:
Typically installed in a horizontal position. Back-draft dampers are installed to prevent backflow
from the stack back into the operating odor control unit on a 2-stage odor control system or system with stand-by fan.
Exhaust Stacks:
Typically installed in a vertical position. Back-Draft dampers are installed in these locations to prevent backflow of
fresh air into an odor control vessel when it is not operational. This is especially important when the system is part
of a two-stage odor control unit. Use of a XO3 Isolation damper in the vessel inlet in combination with a back-draft
damper on the outlet will provide assurance that the second stage pulls 100% of it's airflow from the intended source.
