ACCESSORIES
Inlet Screen (Q, SQ2)
Heavy-gauge steel wire mesh.
Inlet Bellmouth (Q, SQ2)
On unducted inlets, the radius
bellmouth uniformly accelerates air
into the fan, reducing noise and energy
requirements.
Plus Duct Silencer (Q, SQ2)
Significantly attenuates fan airborne
sound levels. Center body of round
silencer is dimensional matched to
Q-fan hub. Center body is field
adjustable in the direction of airflow.
This allows hub to be located close to
Q-fan, thereby reducing flow
generated turbulence and noise.
Silencers can be on inlet and/or outlet
and come in short and long length
versions. Silencers are flex connected
to Q fans and slip connected directly to
Super Q II enclosures. Silencers are
shipped loose for field installation.
Inlet Flange (Q)
Rolled steel ring, factory-mounted, for
flanged duct connection. Sizes 16 to 21
one-inch flanges, sizes 27 to 44 are
1½-inch flanges.
Adjustable Inlet Vanes
11 steel vanes operated by a positive
peripheral control mechanism located
out of the airstream. Each vane is
supported at both ends by a precision
bronze bearing. The control arm is
suitable for manual or automatic
operation. Inlet vanes are shipped
loose for field installation.

Specifications
Outlet Flange (Q)
Rolled steel ring, factory-mounted, for
flanged duct connection.
Outlet Diffuser (Equalizer) (Q)
Steel spinning with 30 degree included
diffusion angle. Permit same size slip-
duct connection on discharge as inlet.
Outlet Screen (Q)
Heavy-gauge steel wire mesh.
Outlet Flow Stabilization
Screen (Q, SQ2)
Similar to outlet screen, but openings
are much smaller. Designed to act as
an airflow stabilization device on the
outlet of each fan.
