Enervex, Inc. Box Ventilator BESF 180

The BESF Box Ventilator is used for bathrooms, kitchens and specialty exhaust and supply applications. For exhaust applications it is installed inl line in the exhaust duct termination point where it ensures a negative pressure in the entire duct system. For optimal performance the fan speed can be controlled by a modulating pressure control (MEC 18). The BESF is also used for supply of combustion air, where it is controlled by an EBC 30 Modulating Pressure Control as part of an MCAS, Modulating Combustion Air Supply system. The exhaust fan is typically used in applications where there are multiple appliances on multiple floors, duct 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.
