Regenerative Blowers

Two new ROTRON brand regenerative blowers have been introduced by Ametek to satisfy a wide range of industrial applications. They can agitate solutions, convey parts and products, perform vacuum hold-down and pick-up operations, dry and clean parts, or sample process and off gases, among many other capabilities. Models DR333 and DR433 clean, oil-free, and quiet blowers incorporate compact, rugged construction engineered for reliable and long service life at point-of-operation. Regenerative air technology develops proper air pressures and vacuums without the higher energy and maintenance costs associated with larger multi-stage or positive air-displacement blowers and compressors. The DR333 achieves 98.6 normal m³/h maximum flows, pressures up to 74.5kPa and vacuums up to 444.5mmHg. The DR433 can develop up to 187 normal m³/h flows, pressures up to 89.6kPa and vacuums up to 447 mmHg. Both models feature rugged cast aluminum housing, impeller, and cover; threaded cast iron flanges; and UL approved 3-phase TEFC motors with permanently sealed ball bearings contributing up to 25,000 hours of service life. The motors can be specified to handle a broad range of international voltage and frequency options. The blowers can be customized with options and accessories to satisfy particular application requirements. Available accessories include flow meters reading in SCFM, filters and moisture separators, pressure and vacuum gages, relief valves, and variable frequency drive package, among others.
