Whether or not the air is clean or laden with dust, all air has mass. This means that as it moves, frictional forces slow it down. Making matters worse, friction increases as the air’s mass and speed increase. 

Friction is created by the air interacting with other materials, including the dust within it, the components it moves through (for example the hose, ductwork, along with other items), and the air itself.
 

The total degree of resistance within this airstream is referred to as static pressure (SP) and it is often measured in inches of water column pressure (WC).

Traditional collectors
Traditional dust collectors are designed to move high volumes of air at low pressure. A well-thought-out and implemented ductwork design is critical to the optimal performance of traditional dust collectors.

High-pressure collectors
In contrast, with high-pressure collectors (97.8” WC) any pressure loss from ductwork will have a negligible impact on the overall performance of the system. In other words, the high-pressure collectors simplify ducting considerations because the ductwork guidelines for traditional dust collectors no longer apply.
