Model NYD & NYB
Options and Accessories
Dampers - Gravity and
motorized dampers are
designed to prevent outside
air from entering back into
the building when the fan is
off. Damper sizes are shown
on the performance pages.
Disconnect Switches - A
wide selection of NEMA
rated switches are available
for positive electrical
shutoff and safety, including
dust-tight, rainproof
and corrosion-resistant.
Switches may be internally
or externally mounted.
Curb Extension Extensions raise the fan
discharge above the
roofline and provide an
accessible mounting
location for dampers. Insect screen bases
constructed with a removable fine mesh are
recommended for applications where insect
entry must be prevented.
Roof Curbs Prefabricated
roof curbs reduce
installation time and
costs by ensuring
compatibility between
the fan, curb and roof
opening. All curbs are
insulated with fiberglass. A wide variety of roof
curbs are available including: flanged, pitched
and sound-absorbing.
Curb Seal - Rubber seal between fan and curb
to assure proper sealing when attached to a
curb.
Coatings - Wide variety of
coatings and colors are
available for decorative to
corrosive applications.
Permatector™ is our standard
coating. Typically used for
applications that require
corrosion resistance in indoor
and outdoor environments.
Hi-Pro Polyester is resistant to salt water,
chemical fumes and moisture in more
corrosive atmospheres. Typically used for
applications that require superior chemical
resistance, excellent abrasion and outdoor UV
protection. This coating exceeds protective
qualities of Air Dry Heresite and Heresite
Baked Phenolic.
Baked Enamel Decorative Coatings are heat
cured enamels applied either as wet paints or
electrostatic powders. Customers can choose
from 16 standard decorative colors or color
match any color.
All coatings with relative resistance charts can
be found in Greenheck’s Product Application
Guide, Performance Coatings for Ventilation
Products.
