Page 4: 1-Principle Of Operation
1- PRINCIPLE OF OPERATION NOVATEC vacuum loaders utilize a powerful motor to create a vacuum, which draws material into a chamber. After the load time setting has expired, the vacuum motor is turned off and the negative pressure in the chamber is relieved. Material in the chamber then falls through the bottom, past the flapper while compressed air is pulsed through the filter to dislodge any contaminants or fines that may have accumulated. -

Machine Mount Models with a sight glass are available as standards for all VL and VLP models. -
