Find Your New Pneumatic Truck Blower at Blocker & Wallace

We offer an extensive range of dry bulk pneumatic blowers and pneumatic trailer parts designed to safely discharge your unique materials at optimal rates. Using air from a truck blower to discharge dry particles is the most efficient and economical way to transport various materials. Pneumatic trailer blowers use a combination of air and pressure to move dry bulk materials through a pipe or line from one area to another. By controlling the vacuum or blowing pressure inside the lines, truck blower systems from Block & Wallace can successfully and reliably transport materials to a collection receptacle.

The Gardner Denver truck blowers for sale at Blocker & Wallace are designed to offer maximum flexibility for your entire fleet. Whether you'd like a smaller carbon footprint, higher airflow or lower maintenance costs, we have a pneumatic blower to meet your needs.

Frequently Asked Questions: Pneumatic Blower for Semi-Trucks

At Blocker & Wallace, we're proud to carry a vast selection of top-rated pneumatic blowers for semi-trucks and trailers. If you need more information about our products before buying, check out the answers to our most frequently asked questions below.


What Is a Blower on a Semi-Truck?

A pneumatic blower for semi-trucks provides a high and wide range of flows for loading and discharging dry bulk products. Dry bulk goods are shipped in large amounts and not packaged or transported the same way as container transport.


How Do You Unload a Dry Bulk Tanker?

You can unload a dry bulk tanker with a pneumatic trailer blower in five steps:

  1. Park the tank truck at the corresponding position of the collection receptacle and position the discharge hose level, then connect the quick connector of the discharge hose to the transport pipeline joint and tighten it firmly.
  2. Close the top pressure relief valve, secondary blow valve and discharge valve, then check whether the front and rear intake valves are open.
  3. Start your diesel engine or power take-off to drive the air compressor to inflate the tank.
  4. When the pressure gauge reaches the correct level, open the secondary blow valve, unblock the pipeline and open the discharge valve.
  5. Once the pressure drops, cut the power, stop the air compressor, close the secondary blow valve and open the tank top pressure relief valve to complete the unload.

How Much Weight Can a Bulk Truck Carry?

Most bulk pneumatic trailers and truck blowers transporting dry bulk goods limit the maximum laden weight to 80,000 lbs. Tandem axle trailers limit each axle to 34,000 lbs.
