Dry Bulk Blower Sales & Repair in Iowa — Ames Hydraulics

A dry bulk blower is what moves powder from a truck or trailer into a silo — and when it’s not working, the load doesn’t unload. Ames Hydraulics sells new pneumatic blowers and repairs blowers of every make in central Iowa. Cement, fly ash, lime, plastic pellets, food powders, and feed — if it’s a powder, granule, or pellet that gets moved by air, we work on the equipment that moves it.

What a Dry Bulk Blower Does

A dry bulk blower pressurizes a dry-bulk tank or truck so the product can be blown into a silo or receiving bin. It’s not a fan — it’s a positive-displacement or rotary blower that generates real pressure. Different products need different blower sizes and different pressures, which is why sizing the right blower for a given haul is a lot of what we help customers with before they buy. Get it wrong and the load takes twice as long to offload, or worse, damages the product.

What We Sell

• Positive-displacement blowers — the standard for cement, fly ash, and heavier powders. Higher pressure, lower flow.
• Rotary blowers — often the right choice for lighter products (plastic pellets, feed, food powders) that need higher flow at lower pressure
• Truck-mount and trailer-mount blower units for dry-bulk hauling
• Skid-mounted blower packages for stationary plant use
• PTO drives, hydraulic drives, and diesel drives — sized to the truck or the plant

What We Repair

The bulk of our dry bulk blower work is repair — because these units get hard use and eventually every rotor, bearing, and seal wears out. Repairs we do routinely:

• Rotor and bearing rebuilds on all major blower makes
• Seal replacement and case gasket work
• Drive-side repair — PTO shafts, hydraulic motors, and gearboxes
• Pressure and flow testing before the blower goes back to the customer
• Welded mount repair where the blower attaches to the truck or the skid
• Plumbing repair — air lines, tank valves, and product lines

Cement, Fly Ash, Plastics, and Feed

Dry bulk blower service isn’t one thing — the product being moved matters. Cement and fly ash are abrasive and eat rotors on cheap blowers. Plastic pellets need clean, oil-free air so contamination doesn’t ruin the load. Feed handling has USDA cleanliness rules. Food-grade powder blowing is regulated. We size and spec the blower to the product, not just the truck. If you’re not sure what you have, bring us the tag and we’ll tell you.

New Blower Sales — Sizing and Delivery

When you buy a new dry bulk blower through us, the sizing conversation happens first. We ask what product you’re moving, how far the run is from truck to silo, what silo backpressure you’re fighting, and what horsepower you have available on the truck or plant. Then we spec a blower that matches. New units ship from the manufacturer with typical lead times of 2 weeks to a month. Install is done locally.

Blower Repair Turn Time

Most dry bulk blower repairs turn in a week or less. Rotor and bearing rebuilds depend on parts availability — usually 3 to 5 days. Complete unit rebuilds are longer. If you have a load stuck and can’t unload, tell us that when you call and we’ll prioritize the visit. Free pickup within 60 miles of Ames.
