SECTION 4 
OPERATION 

 

Future operating problems can be avoided if proper precautions are observed when the equipment is first put into 
service. 

 

Before starting under power, the blower should be turned over by hand to make certain there is not binding or 
internal contact. 

 

Each size blower has limits on pressure differential, running speed and discharge temperature which must not be 
exceeded.  These limits are shown in 

“Maximum Operating Limitations”, FIGURE 4-

 1

, below. 

 

 

Operating beyond the specified operating limitations will result in damage to the unit. 

 

It is important that the pressures and temperatures are measured directly at the ports of the blower to avoid error 
that may be caused by intervening pipe runs, fittings, etc. 

 

Relief valves must be used to protect against excessive pressure or vacuum conditions.  These valves should be 
tested at initial startup to be sure they are adjusted to relieve at or below the maximum pressure differential rating 
of the blower. 

 

NOTICE 

Relief valves should be placed as close as possible to the blower inlet or discharge. 

 

In some instances, pressure may be relieved at a lower point than the blower maximum in order to protect the 
motor or the equipment served by the blower. 

 

Discharge temperature switches are recommended to protect against excessive inlet restriction or inlet 
temperatures.  Check valves in the discharge line on pressure blowers and in the inlet line on vacuum blowers are 
recommended to protect the blower from motoring backwards when shut down under load.
