Horizontal Mounting Legs
Heavy gauge steel support legs welded to the fan
are punched to accept base vibration isolators.
Horizontal Suspension Brackets
Brackets welded to the fan housing for horizontal
ceiling hung applications are punched to accept
hanging neoprene or spring isolators.
Vertical Base or Suspension Brackets
Brackets welded to the fan housing for vertical base
mount or vertical ceiling hung applications are punched
to accept vibration isolators.
Vibration Isolators
Neoprene, housed spring or freestanding
spring isolators for base
mounting are available. Neoprene or
spring hanging isolators are available for
ceiling hung applications.
Special Coatings
A wide selection of coatings resistant to
corrosive environments is available. See
the Engineering Bulletin "Special
Coatings for Centrifugal and Vane Axial
Fans."
Annular Flow Sensor
A single point flow sensor which
provides accurate flow measurement
from a probe positioned in the
airstream.
Variable Frequency Drives
Microprocessor based electronic speed
control for belt or direct drive vane
axials. Explosion resistant applications
require special consideration - consult
the factory.
Electronic Positioner
Uses a 0-20 mA control signal to change
the blade pitch angle on response
control fans. Allows use of
pneumatically operated response
control fans in buildings with DDC
controls. Requires a 60 PSI air supply
(by others).
Motor Cover
A vented steel cover installed over the
motor and drive on belt drive units
provides protection from weather, dust
and dirt while protecting personnel from
rotating drive components.
Belt Guard
Three-sided or totally enclosed belt
guards protect motor pulley and drive
belts, as well as personnel from rotating
drive components. Cannot be used
when a motor cover is installed.
Vibration Switch
This is an adjustable switch that shuts
the fan off immediately in event of
excessive vibration. The switch can be
preset to any level of vibration amplitude
and provides continuous vibration
monitoring. An audible or visual signal
may also be wired to the switch.
Designed for maintenance free service
in permanent installations.
Thrust Restraints
Recommended on installations
where the fan thrust-to-weight
ratio may result in fan movement.
Thrust restraints are typically
installed in pairs at the fan
discharge.
