Blower RPM Calculator

Formula

The formula to calculate the Blower RPM (BRPM) is:

\[ \text{BRPM} = \frac{\text{MRPM} \times \text{MPD}}{\text{BPD}} \]

Where:

\(\text{BRPM}\) is the Blower RPM
\(\text{MRPM}\) is the Motor RPM
\(\text{MPD}\) is the Motor Pulley Diameter (inches)
\(\text{BPD}\) is the Blower Pulley Diameter (inches)

What is Blower RPM?

Blower RPM (Revolutions Per Minute) is the rotational speed at which the blower operates. It is a critical parameter for ensuring the proper functioning of the blower, which is used in various applications such as HVAC systems, combustion air supply, and material handling. The RPM is influenced by the motor speed and the size of the pulleys used in the belt drive system.

Example Calculation

Let's assume the following values:

Motor RPM (MRPM) = 1800 RPM
Motor Pulley Diameter (MPD) = 4 inches
Blower Pulley Diameter (BPD) = 8 inches

Using the formula:

\[ \text{BRPM} = \frac{\text{MRPM} \times \text{MPD}}{\text{BPD}} = \frac{1800 \times 4}{8} = 900 \]

The Blower RPM (BRPM) is 900 RPM.
