Pneumatic Conveying Systems

PTO Grain Vacs The only system you’ll ever need. Gives one-person total grain-handling capability! Do it all with the Walinga Agri-Vac. Fill or empty any storage facility being used. The Walinga Agri-Vac puts an end to legs, augers, sweeps and shovels. Grain handling has never been simpler, safer or healthier.


3510 Agri-vac

Responding to the agri-business demand for something monumentally tough in a compact package Walinga introduces the 3510 AGRI-VAC. There is nothing small about this machine except its size. It’s intentionally narrow 29 inch wide frame fits thru doorways. Transferring bulk at 900 bu/hr or 23 tons/hr, the 3510 is big on performance.

A wee brute of an addition to Walinga’s portable power crew. Processing facilities, feedmills and producers required something small and powerful. The 3510 is a transfer unit moving bulk spills or clean-up from point A to point B. This is not a traditional commercial vacuum collecting spilled material into a self contained bin. It’s much more. PTO, Gas or Electric powered, the nimble 3510 Agri-Vac transfers spills, production waste or bulk quickly and efficiently in spaces less suitable for the larger industrial machines Walinga is known for. Used indoors or out this unit is built to last! Includes the Walinga two year warranty.
