AMETEK Rotron - Inverted Blowers

		Rotron Inverted Blowers

Rotron Trimline inverted blowers are compact, sturdy, quiet and relatively light in weight. They are designed for a long, maintenance-free life. Free delivery airflows range from 22 to 41 CFM. These designs generate static pressure up to 2.4 IWG. Inverted blowers have their driving motor located inside the squirrel cage wheel. This results in unusual compactness and excellent motor cooling. Such an arrangement is only feasible whenever the wheel diameter is large in proportion to the volume of air moved. This situation may be obtained in slow running blowers as well as in tight scroll squirrel cage blowers that have a high pressure-to-volume ratio performance. Models are available in a variety of Brushless DC and AC (50/60 or 400Hz) voltages.
