Application Information Nautilair variable speed brushless DC blowers have been engineered to deliver a measured air/fuel mixture in gas-fired burner systems for optimized combustion and reduced nitrous oxide and carbon monoxide emissions. Mechanical Characteristics Nautilair blowers are designed for combustion applications and are typically mounted directly to the inlet of the burner. The fan housings are sealed to allow for the combustion gas and air to mix inside the blower. Fans have been designed to optimize air/gas mixtures and provide high efficiency combustion. Their design uses an offset motor that allows for higher temperatures and condensation in the fan housing...

What is a Regenerative Blower? A regenerative blower has impeller blades passing the inlet port to draw air or other gases into the blower. The impeller blades then, by centrifugal action, accelerates the air outward and forward. Here the regenerative principle takes effect as the air is turned back by the annular shaped  housing to the base of the following blades where  it is again hurled outward. Each regeneration  imparts more pressure to the air. When the air reaches the stripper section at the outlet (the stripper is the part of the blower Located between the inlet and the outlet...

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...
