2-2 General Description
Our systems create vacuum for the automatic pneumatic conveying of most free-flowing, dry,
pelletized, or granular materials in a central material handling system. Material
characteristics determine the type of equipment needed to convey the material.
A typical use for our equipment is an in-plant distribution system for plastic processing
plants.
Our central vacuum systems are as varied as the applications they service. The tubing and
equipment furnished in our system is designed to convey the material(s) specified at the time
of purchase at specific rates and distances.
We can advise you on your system capabilities based on system makeup, distance, material,
and conveying rates you want.
System capacity is directly affected by the pressure drop in the overall system, such as
number of material line bends, pipe length, Y-tubes, T-tubes, etc.
Note: Vacuum leaks occuring anywhere in your system reduce capacity.
Use the minimum effective amount of vinyl flex hose to maximize material line efficiency.
Keep material lines as straight as possible. Refer to the Mechanical Components Product
manual (Part No. A0536580) for installation recommendations.
