OLI VBS and VBSI bin aerators

The OLI range of bin aerators has been developed to assist in the eradication of problems associated with product flow from bulk storage of dry, fine and granular powders, such as ratholing and bridging. The VBS Aerator is used extensively throughout the food, chemical and grain processing industries worldwide.

Using an FDA-approved food grade silicone membrane with aluminium or food and pharmaceutical grade stainless steel stems, they are suited to a wide range of applications where fluidisation is paramount to encourage product flow.

The VBS and VBSI aerator ranges offer low air consumption, require no maintenance and are compact in design. The advanced one-way directional air flow boosts powder discharge from silos, hoppers or bins. The Tramontana design maximises unloading efficiency due to its unique shape.

With an operating pressure of 0.8–4 bar and a continuous and discontinuous duty cycle, they come in two sizes — the VBS Standard (104 mm) and the VBSM Micro (60 mm) — and are available in high temperature (170°C), food grade metal detectable and the standard food grade model with aluminium or stainless steel stem.

Using the VBS RP Kit the aerator range can also be retrofitted to silos, bins or hoppers while full or where internal silo access is difficult or impossible. Constructed from stainless steel and supplied with internal seals and fittings, they are easily installed.
