Can a furnace blower be used as dust collector?
The average static pressure of most small dust collection systems is 8″ to 10″. In other words a furnace blower does not have enough strength to overcome the static pressure of a central dust collection system. Also, the blower is not designed to handle dust.
Is 650 cfm enough for dust collection?
A 3/4 -hp, 650 CFM collector, like the wall-mounted unit shown below might be the perfect solution for a small shop. It’s small enough to move around the shop as needed and conveniently hangs on the wall, out of the way of your tools.
What are squirrel fans used for?
A squirrel cage blower, also known as a centrifugal blower, is used to move air and gases in a variety of applications. This equipment is so named since its construction looks similar to that of a hamster wheel.
How does a squirrel cage fan work?
The fan wheel rotates clockwise or counter-clockwise, with the small forward-curved blades scooping the airflow and slinging it out as the wheel rotates. It is designed to move high-volume airflow with very little static pressure.
How do you calculate CFM for dust collection?
For a rectangular port, calculate the area (multiply length times width, in inches). Then, multiply that area times 28 to find the approximate flow in CFM @ 4,000 feet per minute (FPM).
How do I know if my blower is CW or CCW?
Wheel Diameter: Measure the diameter of the blower wheel – the longest distance from one side of the ring to the other side. From the appropriate perspective described above you will see the wheel is spinning clockwise (CW) or counter clockwise (CCW).
Which way should a squirrel cage fan turn?
Why is it called a squirrel cage fan?
A squirrel cage blower, also known as a centrifugal blower, is used to move air and gases in a variety of applications. This equipment is so named since its construction looks similar to that of a hamster wheel. Squirrel fans are known for their superior energy efficiency compared to other types of blowers.
