Bent Frame:

  Ventry Solutions’ positive pressure fan is by no means symmetrical.  If 

you position yourself behind the fan on its right side, the closest leg should be angled several 
degrees ahead of the left leg.  This same leg also leans out more than the left leg does.  These are 
design aspects engineered into the fan to increase the stability and to prevent walking.  Figure 1 
gives you an idea of how it should look.  If the legs do not resemble the picture, the frame or leg 
may be bent and will need to be straightened or replaced.  Contact the manufacturer.
 

Operating Surface:

  Some surfaces such as wooden decks or stairways vibrate causing 

the fan to walk.  Adjusting the throttle will sometimes eliminate this problem.  Some fans will 
move backwards if placed on extremely smooth surfaces.  Because the fan produces up to 17 
pounds of thrust, surface friction may not be great enough to keep the fan stationary.  In this 
case, reduce the throttle until the fan quits moving.   

Leg movement obstructed 

If a front or rear leg sticks, several things may be occurring.  First, check to see that the 

leg adjustment handles are completely loosened.  If this is not the problem, remove the crutch tip 
and roll pin, then remove the leg from the frame.  Then file the inside of the frame where the 
adjustment handles are inserted.  Also check around the top of the frame to see if obstructions are 
present.  Remove any dirt and grease that might be clogging the frame.  On rear legs, the top leg 
hole may require a light filing to remove any roughness.  If a leg is still not sliding freely, check 
the frame and leg for any abnormal bends.  Replacement may be necessary.  

Fan too large to fit compartment
