The 37SST "StealthTM" Series are only 11" (279) high and have been specifically designed for shallow ceiling plenumapplications, which are common where zoning requirements limit building height and the architect wishes to maximize the number of floors. Utilizing "StealthTM" design technology, this terminal has industry leading low sound levels.


  • 20 ga. (1.00) galvanized steel construction.

  • 16 ga. (1.6) galvanized steel inclined opposed blade primary air damper. 45O rotation, CW to close. 1/2" (13) dia. plated steel drive shaft. An indicator mark on the end of the shaft shows damper-position. Leakage is less than 2% of nominal flow at 3" w.g. (750 Pa).

  • "StealthTM" design technology provides significant reductions in radiated sound levels.

  • Perforated baffle on primary air discharge optimizes mixing with induced air for rapid and effective temperature equalization. The baffle also converts low frequency primary air valve generated sound into more readily attenuated higher frequencies.

  • Pressure independent primary airflow control.

  • Multi-point averaging flow sensor.

  • Terminal may be field installed either way up, providing the additional flexibility of right or left field connections.

  • Access panels are full size on top and bottom of terminal for ease of maintenance and service.

  • Energy efficient PSC fan motor with thermal overload protection.

  • Motor blower assembly mounted on special 16 ga. (1.6) angles and isolated from casing with rubber isolators.

  • Adjustable solid state fan speed controller with minimum voltage stop.

  • Hinged door on fan controls enclosure.

  • 1/2" (13), dual density insulation. Exposed edges coated to prevent air erosion. Meets requirements of NFPA90A and UL 181

  • Available with electric or hot water supplementary heat.

  • All controls are mounted on exterior of terminal providing ready access for field adjustment.

  • Each terminal factory tested prior to shipment.

  • Single point electrical and/or pneumatic main air connection.

  • Discharge opening designed for flanged duct connection.
