The 30HQX Hospital Grade exhaust terminal unit has been purposely designed to provide optimum performance, while addressing the needs of hospital and other critical environment applications where indoor air quality (IAQ) is a concern. Standard features, like the access door and removable flow sensor, ensure that maintenance is simplified.

The standard fully insulated dissipative silencer is designed to minimize undue pressure loss while maximizing attenuation, specifically in the 2nd and 3rd octave bands.


Standard Features

  • Venturi valve inlet for reduced pressure drop.
  • 22 ga. (0.86) zinc coated steel casing, mechanically sealed, low leakage construction.
  • 16 ga. (1.63) corrosion-resistant steel opposed blade damper with extruded PVC seals. 45° rotation, CW to close.
  • Tight close-off. Damper leakage is less than 2% of the terminal rated airflow at 3" w.g. (746 Pa).
  • 1/2" (13) dia. plated steel drive shaft. An indicator mark on the end of the shaft shows damper position.
  • Multi-point averaging Diamond Flow Sensor. Aluminum construction. Supplied with balancing tees.
  • FMI Diamond Flow Sensor is insert type design to permit easy removal for cleaning. Secured with thumb screws.
  • Side access door allows quick access to flow sensor.
  • Rectangular inlet and discharge with slip and drive cleat duct connection.
  • Full NEMA 1 type controls enclosure for factory mounted controls.
  • VAV section lined with 13/16" (21) thick, 4 lb. density Steri- Liner insulation. Fiberglass with a reinforced aluminum FSK facing. Meets the requirements of NFPA 90A, UL 181 and ASTM C655.
  • "Notch and tuck" fabrication and full seam length steel Z-strip construction.
  • Right-hand controls location is standard (shown) when looking in direction of airflow. Optional left hand controls mounting is available.
  • Available in 11 unit sizes to handle from 30 to 8575 cfm (14- 4047 l/s).
