Power Blower Information
The Industrial Power Blower is a high powered, portable blower used for
Positive Pressure Ventilation (PPV), a ventilation technique that quickly and efficiently replaces hazardous
interior environments. PPV was pioneered in the fire fighting industry where fire fighters use the blowers to
ventilate smoke, heat and harmful gases from buildings. This creates a safer environment for them to
work in and makes it easier for them to find victims and extinguish the fire.
PPV relies on two principles, (1) a cone shaped air pattern, and (2) pressure. To accomplish Positive
Pressure Ventilation, the blower is placed on the outside of the structure. It is positioned so that the cone
shaped air pattern created by the blower completely seals the entrance opening (
Figure 1.3
). When this
seal is achieved, the air pressure is increased equally at all points inside the structure. When an exhaust
opening is created, all of the interior air moves in one mass towards it. The result is fast, efficient
ventilation of the entire structure.
For additional information on how to accomplish PPV, refer to “PPV Set-Up Procedures” in this Manual.
Note:
The Industrial Power Blower is the most efficient tool for PPV for two reasons. First, the exclusive
tapered shroud design creates a wide, stable, conical air pattern. Second, the seven blade air
movement impeller used on all of our Industrial Blowers is designed to create high pressure. These
two features make the Industrial Power Blower the powerful ventilation tool that it is.
Operating Procedures
The information and instructions in this section should be routinely
reviewed and followed before the actual operation of an Industrial Power Blower.
Pre-Operation
: VISUAL INSPECTION.
After receiving and unpacking your blower, be sure to
carefully inspect it for any damage that might have occurred during shipping. Should you find any
damage:
PLEASE NOTIFY ICS COMPANY IMMEDIATELY AT: 1-412-824-6933
CAUTION: NEVER MOVE THE BLOWER WHILE IT IS IN OPERATION. SEVERE PERSONAL INJURY IS POSSIBLE
AS WELL AS DAMAGE TO THE BLOWER. ALWAYS SHUT-DOWN THE BLOWER PRIOR TO MOVING!
SET-UP
Position the blower in the desired location, making sure it is placed on a flat, hard and debris
free surface.
