Financial Benefits of Low-Pressure Air Blowers Rotron regenerative blowers result in a cost savings in a number of ways: you’ll experience lower capital expense, a six-month payback on electrical use, enhanced plating quality through aeration, increased production utilizing a consistent continuous plating process, oil-free regeneratives not needing oil filters, and a more reliable, no/low maintenance design. Lower Capital Expense. When you compare the cost of a compressor in a small plating shop against a 5-hp regenerative blower, a compressor can initially cost 4 to 6 times more than the Rotron...

Guidelines for Maximum Agitation Efficiency Once you select the proper regenerative blower, a system design should be planned in order to achieve the most efficient and cost-effective use of the blower. Single Vs. Multiple Blowers. In multiple-tank plating systems, you must determine whether to use one blower per tank, one blower for the entire system, or various blowers on groups of tanks. In-tank air distribution and plating quality is equal in either option, as long as the system layout is correct. Use of multiple blowers will help to control the plating process and the blower efficiency....

Preventing Water Backrush Alternative Sparger System SPARGER MANIFOLD Avoid Excess Air. Never throttle unwanted blower air. Dumping and bleeding air are recommended so that the blower air is not overpressured and does not over- heat. Overheating can drastically cut the normally long life of the blower. A pres- sure gauge should be installed at the blower outlet to monitor pressure. A relief valve is an excellent safety device to prevent overpressure. Preventing Water Backrush. A low-pressure (0-5 IWG) actuated check valve will prevent water from filling the air path or getting into the regenerative...

Rotron Capabilities Technical superiority. Innovative thinking. A proven commitment to quality. Since it’s inception, in 1949, the name Rotron has been synonymous with reliability, quality, innovation and technical leadership in the field of electromechanical devices designed for the specialized movement of air and gas media. Over the years, Rotron products have become significant contributors within the industrial manufacturing, instrumentation, environmental, processing, air and water pollution control, material handling and medical markets. Rotron’s commitment to supply customized and standard...

Sizing Tools Tool 2. Blower Sizing for Tank Aeration. Tool 3. Blower Selection for Push Air Ventilation. Design Criteria. Chemical baths in process contribute fumes to the air which need to be collected and disposed of. A side collection system is typically added. Since the low-vacuum, high-volume blowers collecting the fumes cannot pull across the entire bath, a Rotron regenerative blower is normally added to push and direct the fumes toward the hood.
