Product Usage Instructions

First use: Before using the equipment, you need to disconnect the purge air source pipe at the front of the equipment and perform air blowing operation. 

This is to clean the water vapor, iron filings, oil stains, raw material tape and other possible impurities in the air pipe. These impurities will cause damage 

to the equipment. equipment has a serious impact. The ideal purge time is 10 seconds per meter.


Purge time: The ventilation replacement amount specified in explosion-proof zone 2 is 5 times the motor volume, and the ventilation replacement amount

 specified in explosion-proof zone 1 is 10 times the motor volume.


The calculation method is: motor length (decimeter) * width (decimeter) * height (decimeter) * coefficient (the second zone is 5, the first zone is 10) - 

rotor volume (cubic decimeter) = purge volume (liter)


Purge volume (L)/flow orifice plate (NL/min) = time (min)
