FEATURES U025 and U060 Aeration Nozzles can be easily fitted on bins or silos from
• Suitable for cement, lime and similar powders outside which makes them particularly suitable for retrofitting or in cases
where the inside of a bin or silo cannot be accessed.
OL-U025 0.2 bar The plastic insert with the sintered metal nozzle is screwed into the steel
OL-U060 1.0 bar Price nipple which has been previously welded on the outside of the bin or silo.
£27.83 Then the connection with the compressed air line has to be carried out.
£30.61 That’s all.
U025 and U060 Aeration Nozzles are used with fine powdery materials at
a working pressure of 0.2 bar (3 PSI). Decades of experience have shown
that virtually all materials can be successfully fluidised at intermittent
operation according to Pulse-Jet or Felder System.


FEATURES Vibrating Bin Aerator types VB, VBE, VBI and VBM combine product
• Sturdy design aeration under operating pressure reaching 6 bar (87 PSI) with an
• Self-cleaning additional slight vibration on the silo wall (see data sheet for sizing,
• Abrasion-resistant positioning and number of aerators). Due to its design, damage of the silo
• Easy to install is impossible even with abrasive materials. An additional backstop valve
• For powders and granular products is not required as, due to the work pressure of 2 to 6 bar (29 to 87 PSI),
no material can enter the zone beneath the elastic FDA-approved silicon
VIBRATING BIN AERATORS lip. OLI® Vibrating Bin Aerators are used for the improvement of mass
flow with powders and granular materials. Thanks to FDA-approval the
Part Number DESCRIPTION CFM @ 6 bar 6200 Vibrating Bin Aerators are suitable for food-grade applications. To meet the
OL-VBM MINIATURE 4.23 most demanding user requirements a stainless steel shaft version (VBI)
OL-VB 8.82 Price is available.
OL-VBI 8.82 £41.11 FUNCTION
OL-VBE FDA APPROVED 8.82 Compressed air is introduced into the stored material through the silicon
£65.66 lip which adheres to the inside silo wall. By varying the work pressure
EXTERNAL within a range between 2 and 6 bar (29 to 87 PSI) the intensity of vibration
MOUNT TYPE of the elastic silicon lip can be changed. Due to interval operation and a
maximum operation time of five seconds air consumption is very low.



• Suitable for cement, lime and similar powdery materials Due to the semi-convex shape of the durable polymer I100 Aeration Pads,
air is given off at a wide emission angle across the entire white surface.
Working temperature: -20 to 80° C (-4 to 180° F)
Fluidisation equipment is used as a preventive measure. A variety of
AERATION PAD materials will show perfect mass flow as soon as a certain amount of air is
added at regular intervals during discharging of the bin or silo. With I100
Part Number OPERATING PRESSURE 6200 Aeration Pads the action is gentle at an operating pressure of the pad of
OL-I100 0.2 bar 0.2 bar (2.9 PSI). The air-enriched material gains the desired flowability. At
Price the same time, possible tendencies of the product to bridge, rat-hole, go
£25.30 lumpy or deposit are prevented.
In a single row installation, I100 Aeration Pads are widely used for
materials like cement. More sophisticated applications with alternately fed
multiple rows are for example designed for hydrated lime in storage and
dosing plants where fluidisation is used not only during discharging of the
silo but also to keep the material in motion during longer storage periods.
