1-3 System Capabilities
Sterling central vacuum systems are as varied as the
applications they service. The tubing and equipment
furnished in a Sterling system are designed to convey the
material(s) specified at the time of purchase at specific rates
and distances.
Sterling 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.
