What Is a Pneumatic Trailer?
A pneumatic trailer, also called a dry bulk tanker, uses air pressure to unload fine, powdery dry bulk through hoses into silos and storage tanks. A blower pressurizes the sealed tank and pushes product through the lines, so there is no spillage and the commodity stays clean and contained. Pneumatics are specialized equipment that pay well for carriers who run them.
What Pneumatic Trailers Haul
- Cement, lime, and fly ash
- Frac sand and industrial sand
- Flour, sugar, and starch
- Plastic pellets and resin
- Dry chemicals and minerals
- Other fine, powdery dry bulk
Sealed, Pressurized Unloading
Instead of dumping or gravity-unloading, a pneumatic trailer blows product through hoses into elevated silos using air pressure. The sealed system keeps fine powders clean and contained, and lets carriers deliver into storage that other trailers cannot reach. Running pneumatics requires a blower, hoses, and product-specific handling, which is why these loads typically pay a premium.

Pneumatic Trailer FAQ
What is a pneumatic trailer used for?
A pneumatic trailer hauls fine, powdery dry bulk such as cement, lime, fly ash, frac sand, flour, and plastic pellets, and unloads by blowing the product through hoses into silos using air pressure.
Is there such a thing as a liquid pneumatic tanker?
Not exactly. Pneumatic trailers move dry bulk using air pressure, while liquids ride in tanker trailers. People sometimes say "liquid pneumatic" loosely, but the two are different trailer types: pneumatics for dry powders, tankers for liquids.
What do pneumatic trailers haul?
Common loads include cement, lime, fly ash, frac and industrial sand, flour, sugar, starch, plastic pellets and resin, and dry chemicals. Any fine, free-flowing powder that can be pressure-unloaded is a fit.
