The fan is typically installed hung from ceiling mounting brackets to support the weight. The stack connections are of the flanged connection type and fit most commercial pre-fabricated chimney systems. The motor and impeller is a complete assembly (drive unit) that can be removed from the fan housing without removing the fan from the stack system. The design is a Type B, Spark Resistant Construction. The ventilator housing is made of stainless steel and equipped with an energy-efficient, totally enclosed, variable speed motor, which is mounted outside the air stream. The IPVB Power Venter is an efficient, hightemperature ventilator with backward-inclined impeller. Commercial grade, totally enclosed (TEFC), variable speed, Class A insulated motor with sealed and permanently lubricated bearings.

Patent Pending Typical uses are: mechanical venting of gas-fired or oil-fired boilers and water heaters. The IPVB is for use with condensing and noncondensing appliances where flue gas temperatures do not exceed 650☏ (344☌) for intermittent operation and 575oF (302oC) for continuous operation. It is specifically designed for applications where reliable and efficient operation, low noise level, low energy consumption, variable speed and compact design are of utmost importance. It can be installed in-line in the vertical or horizontal section of a chimney or stack. Product Information Inline Power Venter IPVB Use The IPVB Power Venter is intended for use as a true in-line draft inducer.
