Very Fast Rates – Easy Operation – Convey Anywhere

Avoid moving railcars with our portable conveying solution. 

Pneumatic conveying is an elegant, efficient solution that allows us to engineer systems without excessive use of horsepower. We’ve taken that simplicity and elegance to a whole other level with our portable pneumatic conveying systems.

Our portable solutions allow for material transfer without moving railcars, which can be dangerous and time-consuming.

Instead of moving the railcar (or multiple railcars), an operator can unlock the industrial castors on our pneumatic conveying pot and move it to the next gate or car.

You can also transport the pot via forklift or truck to another location in the same plant or to another site altogether!

Being portable, they can be taken to any site where material needs to be conveyed, such as transloading between railcars and trucks.

Our unique design concept provides for limited maintenance and prevents premature wear on components. Savings in the use of horsepower translates into less system heat and product degradation.

There are many advantages to pneumatic railcar unloading compared to mechanical conveying. Less moving parts means less breakdowns, and an enclosed system means easy dust control. Another important advantage is flexibility in routing – we can convey material to places others can’t, and with our portable solutions, we can convey literally anywhere!

At it’s most basic, a pneumatic conveying system sucks dry bulk material through a tube from one location (railcar, truck trailer, silo, etc.) into a temporary ‘pot’, and then blows the material in a pipe towards it destination, usually another railcar, trailer, or vessel.
