1. Vibrating Bin Aerator types VB (VBE, VBI, VBM) combine
product aeration under operating pressure reaching 6 bar
(87 PSI) with an additional slight vibration on the silo wall
(see rear for sizing, positioning and number of aerators).
Due to its design, damage of the silo is impossible even
with abrasive materials. An additional backstop valve is not
required as, due to the work pressure ranging from 2 to 6
bar (29-87 PSI), no material can enter the zone beneath
the elastic FDA-approved silicon lip. VB-type Vibrating Bin
Aerators are used for the improvement of mass flow with
powders and granular materials. A stainless steel shaft ver-
sion (VBI) is available on request.
Compressed air is introduced into the stored material through the silicon lip which adheres to the inside silo wall. By varying the operating
pressure within a range between 2 and 6 bar (29 to 87 PSI) the intensity of vibration of the elastic silicon lip can be changed. Due to
interval operation and a maximum operation time of 5 seconds air consumption is very low.
