About this file
This document contains technical specifications and certifications for an exhaust fan and roof curb to be provided under a federal contract opportunity. The exhaust fan is a belt drive centrifugal roof exhaust fan model GB-097-4 with a motor enclosure rated for explosion proof use. The fan produces 100 CFM at 0.3 inches water gauge static pressure while operating at 919 RPM and drawing 0.04 horsepower. The roof curb is model GPF-19 with dimensions of 18.5 inches tall, 19 inches wide, and 19 inches long. Both products are certified for high wind and hurricane conditions up to 150 pounds per square foot by Miami-Dade County and the Florida Product Approval program. Relevant options and accessories are specified including a standard curb cap, thermal overload protection for the motor, and a NEMA-rated switch.
The related federal contract opportunity is a special notice for project 573-19-616 to correct electrical deficiencies at a Department of Veterans Affairs medical center on a three-year test basis. Proposals are due by December 5, 2022 at 1:00 PM. The solicitation number is 36C24823R0042 and was issued by the Veterans Health Administration Veterans Integrated Service Network 8.

Spark B construction was selected.
Greenheck has included options and accessories for this product that meet the intent of AMCA 99 - spark resistant construction guidelines. Greenheck recommends, but does not require, an EXP motor for this product line. If an EXP motor is not selected, the engineer of record must determine if this is acceptable for the application. The resulting fan construction in no way implies a guarantee of safety for any level of spark resistance. Spark resistant construction does not prevent ignition of explosive gasses or vapors due to catastrophic failure or from any airstream material that may exist within in a system.
