The Constant Pressure Control can be used to monitor static pressure in a system, automatically adjusting the fan speed to maintain a desired static pressure. This control reduces energy consumption not only by reducing the speed and the energy used by the fan, but will also reduce the amount of conditioned air that is exhausted. Recommended for use in multi-family structures, hotels and schools where demand control ventilation applications exist.

• Dedicated airflow control mode
• NEMA-4 enclosure on all components
• Pressure range of +/- 1.0 inch wg
• Remote pressure transducer provides installation flexibility
• Intended for use with Greenheck's Vari-Green motor and Vari-Green Drive

Galvanized steel wall bracket allows Models CUE and CUBE to be wall mounted, fitting between the building wall and the fan. Bracket mounts directly to the exterior wall surface allowing for a flush mount installation.

Polypropylene trap designed to collect grease residue for sidewall mounted fans. Compatible with CUE/CUBE models, sizes 141-161.

Patented removable plug allows for easy spray or steam cleaning of wheel through the windband.

The two-speed control allows motor RPM (fan speed) to operate between two discreet speeds (A or B) through an SPDT switch or relay connected to the dry contact input or through wet voltage (115-230VAC) applied to the digital input terminal. This control accepts an input voltage of 115/208-240V and is intended for use with Greenheck's Vari-Green motor. Recommended for use in schools, restaurants, multi-family structures and condos where manual or demand controlled ventilation applications requiring high and low speed operation exist.

• Accepts input voltage of 85-277VAC
• Intended for use with Greenheck's Vari-Green motor and Vari-Green Drive

The Constant Airflow Control is used to monitor velocity pressure in a system, automatically adjusting the fan speed to maintain a desired velocity pressure (constant CFM). This control reduces energy consumption not only by reducing the speed and the energy used by the fan, but will also reduce the amount of conditioned air that is exhausted. Recommended for use in multi-family structures, hotels and schools where demand control ventilation applications exist.

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. Up to 10,000 unique VOCs exist and Greenheck's VOC sensor can detect all of them. Recommended for applications experiencing intermittent human traffic including bathrooms, classrooms, cafeterias, or other spaces where quality of air is a concern.

• Adjustments for air quality setpoint, minimum and maximum fan speed
• Fan speed and VOC level are available as analog outputs to be read by a building automation system or secondary device.
