35D Single Duct VAV Box Features

The 35D single duct variable air volume (VAV) unit provides cooling only or cooling with reheat to meet all your application needs. It is designed to allow maximum flexibility in configuration and control. The 35D is offered in 11 sizes covering an air delivery range from 45 to 4000 cfm. The basic unit is a short, high performance unit with a multiple blade damper that provides reduced sound levels. Minimal leakage and effective use of reheat airflow combine to assure optimum utilization of supplied airflow. The low height of the unit ensures an easy fit in all applications. (Size 18 is 17-1/2 in. high; all other 35D units are only 12-1/2 in. high.) The unit casing is 22-gage galvanized steel, lined with ½ in. fiberglass. Both the casing and the optional foil liner meet the requirements of UL-181 (Underwriters' Laboratories) and NFPA-90A (National Fire Protection Association).

Control options include pressure-independent pneumatic, electronic, and Carrier variable volume and temperature (VVT) and Product Integrated Controls (PIC). Both VVT and PIC controls are communicating controls; the PIC units provide a control option compatible with the Carrier Comfort Network (CCN). Pneumatic control units utilize a rack and pinion actuator, allowing simple switch-over from normally open to normally closed applications. Electronic control units feature a new factory-installed enclosure that provides end access for field connections, simplifying installation and increasing flexibility.

The units can be specified with electric or hot water heat, foil-faced lining , multiple outlet assembly (octopus), and sound attenuator.
