Options and Accessories

ALUMINUM CONSTRUCTION

Aluminum construction is available for all direct drive sizes 60-160 and belt drive sizes 70-300.

Speed Controllers

Available for use with shaded pole and permanent split capacitor (PSC)

open motors on model SQ fans. They provide an economical means of system balancing with direct drive fans.

INLET and DISCHARGE GUARDS

Inlet and discharge guards provide protection for non-ducted applications. Guards are fabricated of welded wire on a galvanized steel frame. They are easily removed for maintenance and inspection.

MOTOR COVER and BELT GUARD

For belt driven fans, combination motor cover and belt guards constructed of galvanized steel are available for protection of motors, drives, and personnel. Standard on units specified with UL.

DIRECT DRIVE MOTOR COVER

Formed, galvanized steel motor covers are available to isolate direct drive motors from the airstream. When motor covers are furnished, vents to the exterior of the fan are provided to ensure sufficient motor cooling.

GRAVITY DAMPERS

Gravity or motorized parallel blade dampers (model WD-330) are available

for duct mounting. These dampers feature sturdy galvanized frames with prepunched mounting holes, aluminum blades with felt edges, and a balanced design for minimal resistance to airflow.

CONTROL DAMPERS

Square, opposed blade volume control dampers (model VCD) are available for duct mounting. These dampers feature sturdy galvanized frames with prepunched mounting holes, steel blades with vinyl seals, and flexible metal jamb seals. A balanced design results in minimal resistance to airflow.

Coatings

Wide variety of coatings and colors are available.

Decorative coatings are available in sixteen standard colors.

Protective coatings are available in a choice of five electrostatic applied powders providing an available selection for most environments.

All Greenheck coatings and resistance charts can be found in the performance coatings catalog.

INLET VANE

Variable inlet vane dampers (model IVDE) are available for models SQ and BSQ sizes 140-420 and are factory assembled to the fan. They can be specified for either manual or automatic operation with controls furnished by others. These dampers are constructed of heavy gauge painted steel and feature uniform blade movement for positive control. Companion inlet rings for round duct connections are also available.

Insulated Housing

For noise reduction and condensation control, the interior of the fan housing can be lined with a fiberglass duct liner (1/2 and 1 in. being standard). The optional motor cover can also be insulated.
