Rotary Lobe Blowers
Positive displacement lobe blowers for aeration, pneumatic conveying, and steady low pressure air.
Industrial Blowers: Sales, Sizing, and Service
Rotary lobe, regenerative, and air knife systems, sized to your flow and pressure and serviced from 14 Midwest locations.
Which blower fits my flow and pressure?
Choose by flow and pressure rise. Regenerative blowers are compact and oil free for continuous low pressure and low vacuum at modest flow. Rotary lobe positive displacement blowers move high volumes for aeration and pneumatic conveying. Air knife systems use a blower to deliver a high velocity sheet of air for drying and blow off. Brabazon sizes all three to your duty and supports them from 14 Midwest locations.

Regenerative Blowers
Compact, oil free regenerative blowers for continuous low pressure and low vacuum duty.

Air Knife Systems
Blower powered air knives for drying, blow off, and cleaning on packaging and finishing lines.
Low pressure air, matched to the job
Blowers are the right tool whenever a process needs a large volume of air at low pressure or a modest vacuum rather than the high pressure a compressor makes. That covers a lot of plant work: aerating wastewater basins, conveying pellets and powders, drying product on a packaging line, and providing combustion or ventilation air. Because these are continuous, energy hungry duties, choosing the correct blower type and sizing it accurately has a direct and lasting effect on power cost and reliability.
The three families on this hub cover most industrial needs. Regenerative blowers are compact, oil free, and quiet, and they suit continuous low pressure or low vacuum service at moderate flow with almost no maintenance. Rotary lobe positive displacement blowers move far higher volumes at a steady pressure rise and are the workhorse for aeration and pneumatic conveying. Air knife systems pair a blower with a precision slotted nozzle to turn that airflow into a high velocity sheet used for drying, cleaning, and blow off. Selecting between them starts with the same two numbers every time: the flow you need and the pressure or vacuum you have to hold.
Sizing is where installations succeed or fail. A blower must deliver the required flow at the actual system pressure, which includes duct and diffuser losses, not just the free air rating. Altitude, inlet temperature, and filtration all shift the working point, and a blower pushed past its pressure limit runs hot and wears quickly. On the service side, positive displacement blowers depend on clean inlet air, correct belt tension, and timely bearing and gear oil changes, while regenerative units mainly need clean filters and a clear discharge. We plan sizing and maintenance together so the blower delivers its rated life rather than failing early.

Blower questions, answered first
What is the difference between a blower and a compressor?
A blower moves large volumes of air at relatively low pressure, while a compressor produces high pressure in a smaller volume. Blowers cover aeration, conveying, drying, and ventilation where you need a lot of air flow at a few pounds of pressure or a modest vacuum. When the job needs high pressure for tools or stored air, that is compressor territory. Tell us the flow and pressure and we will point you to the right machine.
How do I choose between a rotary lobe and a regenerative blower?
Match the blower to your flow and pressure rise. Regenerative blowers are compact and oil free and handle continuous low pressure and low vacuum duty at modest flow. Rotary lobe positive displacement blowers move much higher volumes and are the workhorse for aeration and pneumatic conveying. If your duty exceeds the pressure or flow a regenerative blower can hold, a lobe blower is the answer.
Do you repair blowers or only sell them?
Both. Our technicians rebuild and service blowers in the shop and in the field, so you can start with a sale, a rebuild, or ongoing maintenance. See our blower repair page to schedule work, and ask about rentals when a process cannot wait for a repair.
