Dust Extraction

The integrated Rheo Ventilation Sleeve captures any dust that may be generated by the transfer of dry powders. Additional dust extraction ports can be fitted to capture displaced air in the receiving container. Air flow rates are controlled by manual damper valves.

The Product Screener with pneumatic turbine vibrator allows for quick screening of product.

Vibratory Screener

Using a simple pneumatic turbine vibrator, the screener allows for quick screening of material during various product transfer processes. Several vibrator variations and speed settings allow the system to adapt to various applications, from V-Shell Blender discharge to Drum to Drum Weighing operations.


A variety of options are available for the Rheo Product Screener to ensure the final product meets the application needs.

The following are a selection of some of the options available:

• Bag Disposal Port
• Product Chute
• Bag Landing Table
• Backsplash
• Wall Mount Attachment
• Integrated Bin-Lid

Easy Screen Change-Out

Multiple screen mesh sizes are available and can easily be switched out. Should the screener not be needed for a particular operation, the screen can be removed and the device can be used as a simple dust containment control.


The Product Screener can be connected to any in-house dust extraction system or mobile dust collector/filter system. Utility requirements vary according to the diameter of the integrated Ventilation Sleeve (airflow recommendations shown below).

*For Elliptical Ventilation Sleeves, use equivalent circumference.

**Flow recommendations are calculated to provide:
• Capture Velocity [at center]: 150 ft/min (approximately)
• Duct Velocity: 3500+ ft/min
