Vac-U-Max bills its Tube Hopper as a nonmechanical way to reload refill hoppers on gravimetric and volumetric feeders running additive flake or powdered polymer.
Tube Hopper is a straight-walled vacuum receiver, with a full opening discharge valve that prevents the material from bridging and rat holing in the hopper, ensuring quick refilling of the hopper below.
The vacuum conveying system uses almost no floor space and is simple to install and maintain because it has few moving parts.
Vac-U-Max is in Belleville, N.J.
