Enervex, Inc. Inline Boiler Exhaust Fan IPVB 500

The IPVB inline boiler exhaust fan is a mechanical draft fan that is used in conjunction with condensing and non-condensing gas-fired boilers and water heaters. It is installed in the chimney flue system where it ensures a mechanical draft (negative pressure) in the entire chimney or stack system. For optimal performance the fan speed can be controlled by a modulating pressure control (EBC 12 or EBC 30/35). The IPVB is typically used in applications where there are multiple heating appliances, chimney design issues (elbows, long runs etc.), code violations or where additional safety is required. This model can also be used for other exhaust applications with high-temperature exhaust air.
