Greenheck airflow measuring products are available with either differential pressure based technology or thermal dispersion technology. AMS is accurate air flow measuring station with pressure transmitter proportional to air flow, while AMD is control air damper combined with airflow measuring station for monitoring and control of air flow. AMD-TD is control air damper with airflow measuring station based on thermal dispersion technology.

UL555 Certified Fire Smoke Damper model FSD-311 is a high performance combination fire smoke damper with Class I leakage with 1 1/2 hrs fire resistance rating. High strength airfoil blades ensure the lowest resistance to airflow in HVAC systems with velocities to 4000 fpm (20.3 m/s) and pressures to 8 in. wg (2 kPa). FSD-311 is available with high performance, fast acting spring return electric actuator / motor with fail-safe function and auxiliary switch for position indication. Actuator can be offered with 24V AC / DC or 230V AC power supply option.   Model FSD-311 may be installed vertically (with blades running horizontal) or horizontally and is rated for airflow and leakage in either direction. Model FSD-311 meets the requirements for fire dampers, smoke dampers and combination fire smoke dampers established by: National Fire Protection Association NFPA Standards 80, 90A, 92A, 92B, 101 & 105 IBC International Building Codes New York City (MEA listing #260-91-M) CSFM California State Fire Marshal Fire Damper Listing (#3225-0981:103) Leakage (Smoke) Damper Listing (#3230-0981:104) Key Features: UL 555 Fire Resistance Rating Fire Rating: 11⁄2 hours Dynamic Closure Rating: Actual ratings are size dependent Velocity: Up to 4,000 fpm (20.3 m/s) Pressure: Up to 8 in. wg (2 kPa) UL 555S Leakage Rating Leakage Class: I Operational Rating: Actual ratings are size dependent Velocity: Up to 4,000 fpm (20.3 m/s) Pressure: Up to 8 in. wg (2 kPa) Temperature: Up to 350°F (177°C) – depending upon the actuator Frame Material : Galvanized steel Frame Material Thickness : 16 ga.
