Questions are often asked about the difference of Grain Vac’s to Grain Augers, or Why would I purchase a Grain Vac?

So in this post we will cover some of the features of the Conveyair Grain Vacs, to make your decision easier & help you understand what’s great about the Conveyair Grain Vac.

Moving Grass Seed

The Conveyair grain vac has the ability to move all types of grain whether it be cereals or small seeds and high value crops due to its positive displacement blower and cleverly designed airlock system.

The smooth cone shape of the main receiver tank allows the grain to gently drop into the airlock and get discharged not allowing any of the lighter product (grass seed) to be lost through the exhaust or block up the vac. The airlock system pushes the material thru and into the discharge pipe without using augers.  This allows the Conveyair to move very small and friable material without damaging it.


Typically grain is required to be shifted out of silos a fair distance from where the vac can be located. No matter what the length of the vac hose, the drop in performance is very minimal on a Conveyair.  This is due to positive displacement blower which creates a greater suction force and lower air speed. Lower air speed protects grain quality and reduces machine wear.  With a Conveyair you get better grain quality, and great suction force moving more grain in less time.


Every Conveyair grain vac includes a dust collection system which is called the Blower Protection System (BPS).  The BPS collects the dust and allows the operator to dispose of it. The lower air speed allows the BPS to be very efficient in removing foreign materials and separating them from the grain and filtering them into the dust bin. This results in the grain being cleaned and light debris such as mold or bugs can be collected & removed efficiently.

Safety First.

Moving sweep augers can be a dangerous thing.  The Conveyair vac has no augers on it at all and the hosing system is very light and easy to handle.  The cleanup hose is only 5” and makes it very easy for only one person to be in the silo with the vacuum end on.
