Troubleshooting

VentBoss Series 100 Portable is making excessive noise. Check the following:

1.  Make sure the blower wheel is not hitting the venturi.
2.  Check that all motor bolts are securely tightened.
3.  Make sure motor bearings are good. (Amperage rating will be higher than normal.)
4.  Blower wheel could be out of balance.  If the blower wheel has gone out of balance, 

there will be excessive vibration. In this case, please contact the VentBoss Technical 
Department at  1-855-558-VENT.

Little or no suction across intake. Check the following: 

1.  Cartridge filter is loaded.  Review “Pulsing the Series 100 Portable” in Section 600 under 

OPERATION. With the air hooked up press the Solenoid Plunger 25-30 times with a 3-5 
second spacing between each pulse. Make sure the unit is turned off for this process.

2.  If using a fume arm make sure the butterfly valve behind the intake hood is not closed. 

Sometimes this valve will close on it’s own, cutting off  most of the air supply. 

Cartridge filter loads up but no dust in the dust tray. Check the following:

1.  Check that the Manual Pulsing System  is working properly.
2.  Check for oil or moisture on the filter media.  If oil or moisture exists in the air supply it 

will transfer to the cartridge.

In some cases high oil content is introduced in the welding process causing the oil to 
vaporize.  This will cause the cartridge filters to load up prematurely.   Call the VentBoss 
Service Department at 1-855-558-VENT for more information.

Fume Arm falls when extended:

1.  Tighten the friction disk located near the swivel base of the arm. Be sure not to over 

tighten.  (See Fume Arm Adjustment in Section 600).

2.  Fume Arm may be overextended beyond it’s weight limit. Place the arm closer to the 

portable.
