SUPPLY INLETS General

It can sometimes be easier, inside a specific volume, to use supply than to use ex­haust air to control contaminants because of the much longer range of influence air from a supply opening has when the openings have the same size and the same airflow rate. For some contaminants and in some processes it may also be neces­sary to supply additional breathing air to the workers and this air could then also be used to control and transport contaminants. For spot cooling of workers or work pieces it is possible to use point jets originating from specific supply inlets.
