AIR SYSTEMS INTERNATIONAL SVB-E8 Manuel D'utilisation page 2

This series of portable ventilation blowers has been designed for industrial heavy duty
applications in confined space ventilation. These blowers are the primary tool for providing
fresh clean ventilation air to remote work locations. Each work environment should be
thoroughly evaluated by a competent person before selecting the proper blower for a par-
ticular application.
READ AND FOLLOW ALL INSTRUCTIONS
All ventilation procedures should comply with federal, state, and local regulations. Air quality should be
tested prior to ventilating a confined space. A purge chart is provided on the ventilation equipment to help assist
in estimating the approximate time needed to ventilate confined spaces. Air quality should be tested continuously
during confined space occupancy to ensure a stable atmosphere and worker safety because atmospheric condi-
tions can change rapidly. Additional procedures and recommendations are available from federal, state, and local
agencies. DO NOT operate these blower units with the flange or grills removed. DO NOT USE STAN-
DARD ELECTRIC, GASOLINE, OR PROPANE BLOWERS IF VOLATILE OR EXPLOSIVE VA-
PORS ARE SUSPECTED!
