This Tjernlund 75 CFM Universal Fireplace Blower is a professional grade tangential blower and is commonly used to help distribute heat from fireplaces and stoves. These are extremely quiet (1.4 Sones) and won't be heard over a crackling fire. It is small enough to fit where the fan would go on most fireplace units. Simply wire in or add a power cord and you are all set. Use it to push heat away from your fireplace or stove and to where it can be enjoyed!
Why should I get a Tangential Blower?
Tangential blowers are used in applications where low noise is critical and best filled by a uniform airflow over a wide path or air curtain. The wide, narrow band of air is most efficiently used to spread heated air throughout an area.
Tangential wheels are usually more efficient when a focused flow of air is required to heat an immediate space. When used in this manner, the air does not have to travel long distances, but instead is used in the immediate surroundings such as in wood stoves and gas fireplaces.
One of the reasons that tangential wheels are quieter in comparison to a centrifugal-style blower is that for products with the same CFM rating, the air speed of the tangential wheel is much slower since the outlet area is much larger than that of a centrifugal blower. This can be seen as an advantage because the large area of discharge of the tangential blower does not require additional diffusion, which would create losses and, thus, decrease efficiency.
