Pneumatic tank trailers and frac tanks for cement, sand, and dry bulk. Working Iron sells, finances, and ships them nationwide.
Pneumatic tank trailers haul dry bulk such as cement, sand, fly ash, and frac sand, unloading by air pressure through a blower. Frac tanks and liquid tanks store and move water, fuel, and other liquids on job sites.
Capacity, tank material, and the product you haul decide which trailer fits. Dry bulk trailers need the right hopper count and a blower, either on the truck or the trailer. Liquid tanks must be rated for the specific product, including whether it needs a DOT code rating.
