1. Despite the fact that many in industry use the terms interchangeably, technically there’s a difference between compressors and fans and blowers. In short, compressors pressurized gases within controlled volumes to ultimately facilitate some type of work. Fans move large gas volumes with slight pressure increase. Blowers move large gas volumes with moderate pressure increase. Further differentiation is made between blower subtypes, as regenerative blowers are generally applied in designs needing high-pressure movement of low airflow, and centrifugal blowers are generally for low-pressure movement of large airflow. 2. Most blowers use one of four motor types — and that largely...

1. Bolt It Down - Any blower must be secured against movement prior to starting or testing to prevent injury or damage. The blower does not vibrate much more than a standard electric motor. 2. Filtration - All blowers should be filtered prior to starting. Care must be taken so that no foreign material enters the blower. If foreign material does enter the blower, it could cause internal damage or may exit at extremely high velocity. Should excessive amounts of material pass through the blower, it is suggested that the cover(s) and impeller(s) be removed periodically and cleaned to avoid...

When you are searching for a solution, you've already got a few parameters in place to help you make your decision. But do you know everything about the product you need? Let's take a look at a few parameters that may be helpful when you're considering a brushed or brushless motor. Motor Performance For each type of motor, there are different performance Levels that depend on size, voltage, flow and impedance. Brushed motors typically have higher air performance than brushless motors due to their simple design. They also only work as an open Loop system, while brushless motors can be...

Troubleshooting Blower Disassembly WARNING: Attemping to repair or diagnose a blower may void Rotron's warranty. It may also be difficult to successfully disassemble and reassemble the unit. 1. Disconnect the power leads. CAUTION: Be sure the power is disconnected before doing any work whatsoever on the unit. 2. Remove or seperate piping and/or mufflers and filters from the unit 3.Remove the cover bolts and then the cover. NOTE: Some units are equipped with seals. It is mandatory that these seals be replaced once the unit has been opened.  4. Remove the impeller bolt and washers and then remove the impeller. NOTE: Never...

In bypass motors the work is independent from the cooling air. A separate fan directly cools the motor armature and field. Usually the cooling air enters and exists through slots in the equipment housing.  Bypass blowers are electric-motor-driven blowers that segregate two paths of air: • Working Air: the path of air for performing the application’s blowing or vacuum function • Cooling Air: the path of air to cool the blower’s motor during operation. In contrast, through-flow blowers make double use of a single stream of blower airflow by channeling that flow over the motor and electronics for cooling.   ...
