Projects are revised
Changed process requirements, layouts and equipment specifications can leave purchased blowers outside the final installation scope.

How surplus develops
The flow requirement changes.
The equipment often stays behind.
Rotary lobe blowers are positive displacement machines used to move air or gas in industrial processes. Equipment can become surplus when a plant changes its capacity, replaces a package or closes a production line. A clear asset review helps distinguish required backup units from equipment available for sale.
Systems are upgraded
Revised aeration systems, conveying equipment and process utilities can release previous blower units and spare assemblies.
Sites consolidate
Plant closures, duplicate purchasing and shared maintenance programs can reveal more blower inventory than operations require.
Check with maintenance and process engineering which units remain needed for active service, backup capacity or planned projects before declaring equipment surplus.
Define what is available
Bare blowers, spare stages and packaged systems.
We welcome inquiries about identifiable rotary lobe equipment in a range of configurations. Describe the actual machine and included components rather than assuming every blower package has the same scope.
Bare blower stages
Standalone units without a complete motor-driven package. Include model, serial number, shaft arrangement, port configuration and available specifications.
Motor-driven packages
Skid-mounted assemblies with motors, drives and accessories. Identify the blower and motor separately and list all supplied components.
Two- & three-lobe designs
Units identified by documented rotor design. Preserve exact model codes rather than inferring the internal configuration from external appearance.
Pressure-service equipment
Blowers held for applications such as aeration and pneumatic conveying. Include the documented operating point and known original service.
Vacuum-service configurations
Units documented for suction or vacuum duty. Identify the specific design and allowable conditions; do not assume every pressure blower is suitable for vacuum service.
Enclosed & accessory assemblies
Acoustic enclosures, silencers, inlet filters, controls and related stock. Identify these separately and state which items form part of the offered package.
Recognizable names. Exact configurations.
Start with the manufacturer.
Keep the full equipment identity.
Common names on industrial rotary lobe blower inventory include the manufacturers and product families below. Other brands and legacy units are welcome in an inquiry.
AERZEN · ROOTS · Sutorbilt · Dresser · Tuthill · Robuschi · KAESER
Brand names identify equipment only. Rotary Lobe Blowers does not claim manufacturer authorization, endorsement or affiliation.
A motor nameplate does not identify the blower.
Capture labels on the blower, drive motor, gearbox where present and package controls. Model options can distinguish orientation, seals, materials and operating limits.
- Manufacturer, full model and serial number
- Motor power, speed and electrical supply
- Inlet and discharge size and arrangement
- Drive type and documented speed ratio
- Package identifier and accessory model codes
Condition and service history matter
Separate unused spares from removed equipment.
New units, stored unused stock, used equipment and rebuilt blowers should be described separately. Share original service, last known operation, storage history and available maintenance records.
Disclose abnormal noise, vibration, leaks, corrosion, seizure, known rotor damage and missing parts. A shaft that turns freely does not establish clearances, internal condition or operating performance.
For rebuilt units, include the documented scope of work. Identify known gas exposure, process residue and cleaning requirements before discussing handling or shipment.
Keep performance data in context
Flow and pressure need a stated operating point.
Performance information should include speed, inlet conditions and pressure differential where available. Distinguish actual inlet flow from standardized flow values and keep their units clear.
Motor horsepower alone does not establish blower capacity. Share original curves or datasheets rather than estimating output or suitability for a different gas.
Define the package scope clearly.
List baseplates, guards, couplings or belts, silencers, filters, valves, enclosures and controls. State whether the package is complete and identify removed components.
Application suitability and any testing, isolation or removal should be evaluated by qualified personnel using the specific equipment documentation and process requirements.
From idle assets to a clear inquiry
Start with the equipment information you have.
An asset list, partial stock export or readable photos can establish the starting point. Be clear about what has been identified, inspected or tested.
Confirm genuine surplus
Check active systems and backup requirements. Select blowers no longer needed for current operations or planned internal use.
Define the lot
Collect labels, photos and available records. Identify complete packages, separate stages, included accessories and known condition.
Discuss selling the equipment
Share the details, location and timing. Inventory fit, commercial terms, inspection needs and removal or transport responsibilities are confirmed for the specific assets.
Value and logistics belong together
Look beyond the original purchase price.
Potential resale value depends on identification, configuration, condition, completeness, documentation and demand. A familiar brand or high original investment does not guarantee an offer.
Explain removal requirements early.
Share dimensions, known weights, access constraints and whether equipment remains connected. Identify any process residue or special handling concerns.
Agree on disconnection, cleaning, loading and transport responsibilities before work begins. Retain manuals and keep accessories linked to the correct unit.
Common questions
Selling surplus industrial rotary lobe blowers
Can I inquire about used blowers?
Yes. Describe prior service, known faults and last operation. Include photos and available records. Used or untested condition needs to be considered during review.
Can I include bare units without motors?
Yes. Identify them as bare blower stages and list any supplied baseplates, couplings or other parts. Disclose missing components.
Should I include motor and control information?
Yes. Record the motor and blower labels separately and describe included drives, control panels and accessories. Do not infer blower capacity from motor power alone.
What if the blower was rebuilt or has been stored for a long time?
Share rebuild records, storage conditions and any preservation information. State when operating status is unknown rather than describing the unit as verified operational equipment.
Can I submit installed packages or a mixed lot?
Yes. Define each unit and its scope, location and connection status. Include an asset list or overview photos and explain any removal deadline.
Is there a minimum quantity or guaranteed purchase?
Share the equipment you have. Whether a transaction makes sense depends on the units, condition, quantities and logistics. Any offer or commercial arrangement is confirmed after review.
Put idle blower equipment on the agenda
Have rotary lobe blowers your company no longer needs?
A spare stage, unused project unit or complete industrial package — start with the details you have.
