A technical post! Now we will provide some technical content to the blog. A brief overview of how positive displacement blowers operate follows.
Positive displacement blowers do not generate pressure internally. Instead, PD blowers overcome line pressure when they are in operation. Air enters the inlet port of the blower and is trapped as the impeller rotates beyond the limits of the port opening. There is no contact between the moving parts inside of the machine. The air is trapped by the tight tolerances between the impeller and blower casing. The air is moved around the impeller and blower casing to the opposite side of the blower towards the discharge port. Once the impeller chamber opens into the discharge port there is an equalization of pressure between the impeller chamber and the discharge line. As the rotation continues, the air is forced out the blower and the process repeats. The following illustration should help explain the process of how a PD blower overcomes line pressure.
Different applications require different blowers. There are various types of blowers available and Universal Blower Pac selects the appropriate blower based on the needs of the facility. We analyze the needs of the process or facility and package the right blower to maximize efficiency, lower noise, or reduce costs, whatever your prerogative may be!
