Automatic Exhaust Fan Control is an intelligent system that assesses the varied energy requirements throughout the work period, adjusting fan speeds automatically for optimal energy usage on the basis of continuous sensor assessment of actual cooking activity. The system includes:

• Microprocessor controls with sensors fitted into the hood and exhaust system
• Variable-frequency drives that regulate fan speed based on the basis of continuous assessment of cooking activity (steam, smoke, and exhaust air temperature)
• A single processor and one keypad to control up to four hood stations - making operation descisions concerning the precise levels of energy required for comfortable, efficient, and safe operation
• Significant savings on fan energy usage, maintenance, and fan life – as well as conditioned supply air during idle or low- or non-cooking periods
• Low installation cost per hood
