![]() The cupped side of the blade pushes the air (at the outside edge of the wheel – see pic below), which creates low pressure inside the wheel, thereby drawing a continuous flow of air into the inner area of the wheel, then to the outer edge where it gets pushed against the inside wall of the housing till it exits the opening in the housing. Is of a squirrel cage that would spin clockwise. A reversed inclined would spin counter clockwise. What kind of Cage spins clockwise or counter clockwise? The intake of air is in the center of the wheel, and the discharge of the air flow is in the direction of the blue arrow. This is a squirrel cage type blower….as viewed in this photo, it rotates in a clockwise direction. For centrifugal fans, discharge is the direction the fan outlet points. For DWDI or Arrangement 3 SWSI fans, it is the side of the fan housing at which the belt drive sheave is mounted. The drive end is is the side of the fan housing through which the fan or motor shaft protrudes. How is the rotation of a fan determined?įan rotation is determined by looking at the fan from the drive end. a motor with a rotational speed of less than 1300 rpm. These fans are frequently used on a “slow” speed motor, i.e. Fan Direction in the Winter To help move warm air thats trapped near the ceiling, blades should turn forward, in a clockwise motion. This type of fan can rotate in both directions, without any change in fan power consumption and air volume. The intake of air is in the center of the wheel, and the discharge of the air flow is in the direction of the blue arrow.Ĭan a centrifugal fan rotate in both directions? Consequently, how do you determine the rotation of a blower motor? How does a squirrel cage air blower rotate? This is a squirrel cage type blower.as viewed in this photo, it rotates in a clockwise direction. If you see a ceiling fan, the inner part is made static by holding it with a hook or so and outer part is allowed to rotate and hence it goes in counterclockwise direction. How do you determine the direction of a squirrel cage fan turn? This usually calculates out to about a 1/4 to 1/3 HP blower motor. On a two-ton system that is 880 cfm (cubic feet per minute). The rule of thumb is the blower should produce 440 CFM (cubic feet per minute) of air per ton. Reversing your fan, to a clockwise direction, creates a gentle updraft, recirculating heat down. The airflow directly underneath the ceiling fan should push down, creating a wind-chill effect, which is going to make you feel cool. This equipment is so named since its construction looks similar to that of a hamster wheel. During the summer, use your ceiling fan in the counterclockwise direction. A squirrel cage blower, also known as a centrifugal blower, is used to move air and gases in a variety of applications. ![]()
