Shutter Types and Construction

Automatic

Automatic shutters are constructed with galvanized steel
frames and drilled for ease of installation. Aluminum felt­edged blades open from fan pressure and close automatically
when fan is off. All aluminum construction is available as an
option.

Motor-Operated, End-Pivoted

Used for exhaust only. Constructed of galvanized steel frames
and aluminum felt-edged blades. Flanges are drilled for ease of
installation. Motor-operated units are furnished with electric
actuators. These actuators are not equipped with end switches.
All-aluminum construction is available as an option.

Motor-Operated, Center-Pivoted

Can be used in either supply or exhaust applications.
Constructed of galvanized steel frames and blades with stain­less steel jamb seals. Blades are held in place with oil-impreg­nated bronze bushings. Motor-operated units are supplied
with electric actuators that are furnished with end switches.

Extra Heavy-Duty

Extra heavy-duty shutters are recommended where discharge
velocity exceeds 2400 FPM or where velocity is low and exces­sive fluttering action is a concern. All extra heavy-duty shutters
have 16-gauge aluminum blades. Can be provided as auto­matic, manual or motorized operation.

End Switch For Motor Operated Shutter

Motor operated shutters used in air-handling systems should
be wired to allow the shutter to open before the fan is started.
A shutter end switch should be mounted in the fan starter
circuit. The shutter end switch may be one of two types:

1. LEVER OR LINKAGE ACTUATED: Allen Bradley
802TAW1 or equal. Mount switch to be actuated by shutter
linkage or shutter leaf when shutter is approximately 80%
to 90% open.

2. MOTOR MOUNTED AUXILIARY SWITCH: Switch
mounts on side of motor opposite shutter linkage and is
actuated by shaft. Set so cam actuates switch when shutter
is 80% to 90% open.

The following end switches can be used on various motors.
A. Control Transformer (115V Secondary)
B. On-Off Selector Switch
C. Shutter Motor (115V)
