Exhaust Air

General

Exhaust air options shall include no relief, 100 percent modulating exhaust fan and 100 percent modulating exhaust fan with direct space building pressurization control.

Exhaust fans shall be either standard or low airflow

No Relief (Standard)

Relief air opening shall be sealed with panel and made watertight.

100 Percent Modulating Exhaust Fan Option

Fan design shall be double width, double inlet forward-curved type. Fan shall be mounted on a shaft with fixed sheave drive. All fans shall be dynamically balanced and tested in factory before being installed in unit. It shall be test run in unit as part of unit test. Fan operating envelop rpm shall be below first critical speed. Fan shaft shall be mounted on two grease lubricated ball or roller bearings as applicable designed for 200000-hour average life. Extended grease lines shall be provided to allow greasing of bearings from section base rail.

Fan motor and assembly shall be mounted on common base to allow consistent belt tension with no relative motion between fan and motor shafts. The entire assembly

shall be completely isolated from unit with 2-inch spring isolation. Discharge dampers at unit outlet shall modulate exhaust airflow in response to OA damper position.

100 Percent Modulating Exhaust Fan with Statitrac™ Control Option

Fan design shall be double width, double inlet forward-curved type. Fan shall be mounted on a shaft with fixed sheave drive. All fans shall be dynamically balanced and tested in factory before being installed in unit. Exhaust fan shall be test run as part of unit final run test. Fan operating envelop rpm shall be below first critical speed. Fan shaft shall be mounted on two grease lubricated ball or roller bearings designed for 200000-hour average life. Extended grease lines shall be provided to allow greasing of bearings from section base rail.

Fan motor and assembly shall be mounted on common base to allow consistent belt tension with no relative motion between fan and motor shafts. The entire assembly shall be completely isolated from unit with 2-inch spring isolators. For both CV and VAV air handlers, the 100 percent modulating exhaust discharge damper (or VFD) shall be modulated in response to building pressure.

A differential pressure control system, (Statitrac), shall use a differential pressure transducer to compare indoor building pressure to outdoor ambient atmospheric pressure. The FC exhaust fan shall be turned on when required to lower building static pressure setpoint. The (Statitrac) control system shall then modulate the discharge dampers (or VFD) to control the building pressure to within the adjustable, specified deadband that shall be adjustable at the Human Interface Panel.
