Models WIH (intake) and WRH (relief) allow considerable design flexibility and are available in a range of sizes. The weather-resistant blades provide for good protection against the elements under ambient conditions while also providing for exceptional airflow resistance properties. A wide range o
The Vari-Green transformer provides a 24-volt power source from the existing line voltage at the fan to the motor and controls. It has two dry auxiliary contacts (one normally open and one normally closed) available to signal a motorized damper or interlock with other devices.
The two-speed control allows motor RPM (fan speed) to operate between two discreet speeds (A or B). There are two methods for switching between speeds: SPDT switch or relay connected to the dry contact input. Wet voltage (115-230VAC) applied to the digital input terminal The two-speed control inclu
The remote dial or touch remote allows the user to manually adjust a fan’s speed from a remote location. These controls mount to a wall using a 2x4 junction box and are supplied with a wall cover plate. The 24VDC transformer, described above, is included with all orders. The Touch Remote includes a
The Indoor Air Quality – Temperature / Humidity control monitors the temperature and/or relative humidity in a space. It will automatically adjust the ventilation rate to or from a space by increasing or decreasing the speed of the fan based on the desired set point.
The Indoor Air Quality – VOC control senses the level of Volatile Organic Compounds (VOCs) in a space and automatically adjusts the ventilation rate to the space by increasing or decreasing the speed of the fan based on the level of VOCs present. Ventilating based on the VOC concentration assures t
The Constant Pressure control is quite versatile and can be used to monitor either the static pressure or velocity pressure in a system. The control will automatically adjust the fan speed to maintain a desired static pressure or velocity pressure (used for constant CFM) in the system. This control
