Range of Adjustment

Diagram showing the flow pattern of a Becker PVC conveying eductor.

Eductor adjustments give a 50-70 SCFM maximum increase in outlet (B) flow with a 60-80% maximum decrease in inlet (A) vacuum level. Performance may vary somewhat, due to motive pressure level and eductor settings. These figures should be used as a guideline only. Contact your mdi sales representative for application assistance. Other eductor/blower combinations are possible.

  Features

Overview

The Becker ED100-300 series eductors are designed for use with Becker high flow, low pressure, regenerative blowers to provide a convenient means of conveying lightweight scrap materials, such as plastic, textiles, or paper.

The ED series eductors use the blower discharge air to generate high airflow through a venturi, which in turn, generates a vacuum flow that provides the suction necessary to pick the product up. The high discharge air flow then carries the product to a remote location for disposal or packaging.

These Eductors are an inexpensive alternative to operating venturis that require high pressure compressed air from a plant air compressor. Cost of the eductor and blower can often be justified on the savings in energy consumption alone.

With Becker ED Eductors, there is never a risk of product being carried over into the blower. A smooth, wide open bore minimizes places where product can be caught, causing blockage to the line.

Five ED Eductor models are available, which, when used with various Becker blowers, provide a wide range of suction pressures and discharge flows. Suction pressures of between 6 and 35 inches of water, and flows between 100 and 730 SCFM are available. Custom sizes and blower arrangements are available; contact your mdi sales representative.
