Industrial Central
Vacuum Cleaning Systems

System Overview

Central vacuum cleaning systems that support more than one operator usually use a "dynamic" type of vacuum producer.

These machines maintain an equal vacuum while the air volume changes, with horsepower increasing with flow.  To the operator, this means performance doesn't change as the number of operators change.

Normally, the size of hose used is less than 2.5" ID and less than 50 feet long.

Central vacuum systems are made up of six major components: the vacuum producer or exhauster; the filtration system; the discharge device; the conveying or piping network; the hose and tools; and the control system.

All the above must be selected to work specifically for your application.

It's easy to design a vacuum system for the maximum number of operators using the system.  It's not nearly so easy to design a pipe system to accommodate a variable number of users, and ensure material conveys back to the separator without plugging. 

System Overview

Vacuum loading systems are designed to move huge volumes of material.  This type of central vacuum supports one operator and always uses a positive displacement (PD) type of vacuum producer.

Positive displacement machines maintain an equal volume of air while the level of vacuum changes, with horsepower increasing with vacuum.  To the operator, this means the system pulls harder as material flow in the system increases.

This characteristic is the reason PD type machines are used in pneumatic conveying systems.  In fact, given the same horsepower, PD powered vacuums will move three times more material per minute than  vacuum systems with dynamic type vacuum producers.
