Centrifugal Roof Exhaust Fans Models NYD and NYB Direct and Belt Drive August 2008 Model NYD & NYB Standard Construction Features Greenheck’s model NYD and NYB tamper-resistant centrifugal roof exhaust fans provide the industry’s best performance and durability for general clean air applications where tamper resistance is required. • Performance as cataloged is assured. All fan sizes are tested in our AMCA Accredited Laboratory and all models are licensed to bear the AMCA Air Performance seal. • Greenheck subjects these products to extensive life testing assuring you the fans will provide years of reliable performance. Greenheck Fan Corporation certifies that the NYB and NYD models shown herein are licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 211 and comply with the requirements of the AMCA Certified Ratings Program. The AMCA Certified Ratings Seal applies to air performance ratings only. 1 1 2 6 Standard Construction Features 4 7 5 3 2 1 Housing is constructed entirely of heavy-gauge galvanized steel and includes louvered vents for positive motor cooling. 2 Hood is hinged to swing fully open for complete access to all internal components. Open hood is safely supported and will not drop closed. Hinge is steel with protective coating. 3 Internal structural supports are heavy-gauge galvanized steel angles. 4 Drive frames and motor supports are heavy-gauge galvanized steel and are mounted on resilient isolators. 5 Backward-inclined, non-overloading wheel is constructed of aluminum. 6 Heavy-duty ball bearing motor. Single and three phase fans include a NEMA-1 switch. 7 Birdscreen constructed of wire mesh is attached to the structural supports. (Removed from drawing for easy viewing internally) 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. 3 Dimensional Data & Model Number Code B C A 2 1/2 in.
