Fans that are used to evacuate a space or create negative air pressure in a system are referred to as induced draft fans. Occasionally, manufacturing spaces are required by specifications to be maintained at a specific negative pressure. An induced draft is also used to identify the combustion process used in large boilers. When mechanical ventilation is supplied to these boilers, the heat transfer rate increases; the boiler can be reduced in size to produce the same amount of energy as a natural draft. The induced draft fans used in combustion systems are normally high temperature and extra heavy-duty construction.
The New York Blower Company offers literally thousands of different types, models and sizes of air-movement equipment that can be customized and tailored to your specific application. See the chart below for a list of recommended designs, materials and features for induced draft fans & blowers, or contact us to request a quote.
