Applications
For classroom and small office unit ventilator retrofits requiring quiet, code-compliant ventilation, the CF146-650CFM-01 (EC, 110-254 VAC, 1100 m³/h, 180 W) delivers energy-efficient outdoor air supply with low sound levels and easy drop-in replacement of existing fan units. In larger lecture halls, cafeterias, and open-plan spaces where higher air exchange rates are needed, the CF160-2000CFM-01 (EC, 110-254 VAC, 3400 m³/h, 360W) provides the increased airflow capacity to meet ventilation demand while maintaining EC motor efficiency. Both models are suitable for unit ventilator applications in schools, universities, and commercial buildings, operating directly from 110-254 VAC single-phase power for simple integration with existing electrical services. Their EC fan technology supports variable-speed control for demand-based ventilation, reducing energy use during partial occupancy.
