Enervex RSHT 012, Chimney Fans, Horizontal Discharge

“I’ve been in the hearth industry a long time, so I know a lot about poorly-performing chimneys. An ENERVEX Chimney Fan is the best way I know to prevent soot and smoke from coming into a house. I tell my customers that if they want a maintenance-free, problem-free way to stop smoking fireplaces – and save on fuel costs – they need to install an ENERVEX Chimney Fan.” - Former chimney sweep

The Guaranteed Solution to Smoking Fireplaces. Optimize Your Fireplace and Create the Perfect Draft!

The perfect fireplace features a flame that’s just the right size – not too high or too low and that doesn’t allow smoke to escape from the firebox. Today’s energy-efficient homes are designed to keep airflow in the house to a minimum, which saves energy but makes it difficult to create a good draft. A fireplace that doesn’t get a good draft spills smoke, soot, and ash into the house, creating a mess and an unpleasant environment. Regardless of the airflow in your house, an ENERVEX Chimney Fan provides a reliable draft in your chimney – all the time. And you’ll never even notice that it’s there.

Tired of smoke getting into your eyes? The RSHT is the cure. It will literally suck the smoke out from the chimney flue  This high-temperature exhaust fan is typically used in venting solid-fuel fireplaces, BBQs, pizza ovens, and stoves. Installation is clean and easy - and the fan's compact design is barely visible from the ground level. The fan can be recessed or hidden behind the chimney top enclosure.

The RSHT Fan is specifically designed for applications where efficient operation, low noise level, low energy consumption, variable speed, and compact design are of utmost importance. It should be installed at the termination point of the chimney or stack section and can be mounted on masonry or metal chimneys. It is typically mounted in the vertical position but maybe sidewall vented as well. The fan assures a negative pressure is maintained in the entire chimney or stack system. The fan discharges horizontally (vertically, if side-wall vented) at a high velocity. The fan housing is hinged and the top can be opened for easy service and access to the stack. The RSHT is for use where flue gas temperatures do not exceed 1400°F (760°C) for intermittent operation and 1000°F (538°C) for continuous operation. 1x120VAC, 1.25A, 1600 RPM, Axial Vane
