Pneumatic Double Dumps

Pneumatic units are also available with air cylinders, solenoid valves, limit switches and cycle timers.  With these units, the air cylinders control the opening and closing of the flaps.  Cycle timers allow easy adjustment of the number of batches per minute.

Gravity flow units are also available with just counter weights.  These units do not open until enough material has accumulated on the flap to overpower the adjustable counterweight.  Sizes: 6, 8, 10 and 12 inch are the standard range.  Up to 24 inch units can be fabricated.
