What can I do to prevent the blower from exceeding its design capacity? :
Each of our blowers carries a badge showing it’s Model and weight as well as it’s maximum speed and pressure rise.Packaged units will have been sized for a specific duty to match your system requirements and will carry a badge to indicate the pressure, speed, absorbed power and weight of the package as appropriate to this particular application. Exceeding the application pressure may not be detrimental to the blower (as long as it does not exceed the blower capability as shown on the blower badge) but may overload the electric motor or cause the drive belts to slip and could also damage other parts of your system. All packaged sets are supplied incorporating a pressure relief valve which will be set to 10% over the duty pressure but we strongly advise the use of an over pressure switch (to stop the unit if the condition persists) or an unloading valve. This will protect the motor, drive and all parts of the down stream system.
