Wall ring and guard grille axial flow fans
Accessory range
Our fully independent R&D and in-house mass production cover safety guard grilles, round air-guiding nozzles, and square flanged nozzles for flexible installation in any direction and under various environmental conditions.
Airflow performance
Innovative aerodynamic impeller design, energy-efficient EC motors, and maintenance-free ball bearings ensure exceptional airflow with low noise. IP44/IP55 protection and -25°C to +60°C operation support demanding ventilation duties.
Engineering quality
Rely on Blauberg Motoren’s engineering excellence – backed by advanced R&D facilities, precision manufacturing, and rigorous testing from aerodynamic simulation to dynamic balancing.
Deliver high-quality axial ventilation solutions with optimized accessory options, reliable EC/DC platforms, and project-based engineering support.
Direct airflow, efficient motor technology
and rugged product options
Axial fans generate airflow parallel to the motor shaft. Compared with centrifugal fans, they are optimized for high volume flow where static pressure is moderate, making them well suited to heat exchangers, condensers, air-cooled equipment, cabinets, charging infrastructure and general machinery ventilation.
The Blauberg Motoren axial range can be configured around EC, AC or DC motors, with metal or composite blades, guard grilles, wall rings, short nozzles and compact square frames. EC models are recommended where efficiency, acoustic behavior and speed control matter most.
Best-fit applications
- Heat rejection:
- Condensers, dry coolers, chillers and refrigeration packs.
- Equipment cooling:
- Power cabinets, charging piles, automation enclosures and server-room auxiliaries.
- Ventilation:
- Air handling units, roof units, wall-mounted ventilation and industrial exhaust.

Axial fan installation
configurations
Axial fans shall be installed according to the airflow direction and equipment safety requirements. The standard Blauberg axial fan configuration draws air from the front side and discharges air through the rear side.
Keep adequate inlet clearance and avoid obstacles close to the outlet so that the impeller can develop stable airflow with lower noise.

Axial fans:
strengths, limitations and selection guide
High airflow in compact space
Large air volume through a short flow path for condensers, cooling towers, cabinets and wall-mounted equipment.
Flexible installation package
Blauberg axial fans can use wall rings, guard grilles, square flanges or metal casing for OEM layouts.
Efficient EC speed control
Blauberg Motoren EC versions support demand-based control to reduce energy consumption and acoustic load.
Limited static pressure
Best for low to medium resistance systems; long ducts or dense filters may require centrifugal fans.
Installation-sensitive performance
Blocked inlets, tight guards or poor outlet clearance can reduce airflow and increase noise.
Noise rises near maximum speed
A larger fan at lower speed is often better than forcing a smaller fan to maximum output.
| Item | Axial fan | Centrifugal fan | Typical decision |
|---|---|---|---|
| Airflow volume | High airflow | Medium to high airflow | Choose axial for large open-area heat exchange |
| Static pressure | Low to medium pressure | Medium to high pressure | Choose centrifugal for ducts, filters and higher system resistance |
| Installation depth | Compact axial depth | Usually deeper housing | Choose axial where equipment depth is limited |
| Typical applications | Cooling towers, condensers, cabinets, cold rooms | AHU, CRAC, duct systems, high-pressure ventilation | Match fan type to resistance and airflow path |
| Noise control | Good when oversized and speed-controlled | Good when pressure demand is high | Use EC control and validate in the final equipment |
Blauberg Motoren China can help balance airflow, noise, voltage, control signal, protection class and installation accessories so the axial fan works correctly in the final customer equipment.
Designed for stable airflow and
simple system integration
Aerodynamic blade geometry
Swept blade profiles and optimized hub ratios reduce turbulence, improve pressure build-up and support lower sound levels in real installations.

How to specify the right axial fan?
-
Define the operating point
Start with required airflow, available static pressure, inlet temperature, altitude and allowable sound level.
-
Choose motor technology
Use EC where energy saving, low noise, speed control or communication is needed. Use AC for simple mains operation, and DC for low-voltage equipment.
-
Match the installation
Confirm frame size, airflow direction, guard grille, cable exit, mounting orientation, ingress protection and corrosion requirements.
-
Validate in the equipment
Measure airflow, current, sound and thermal margin in the final system because grille, coil and enclosure losses change the fan operating point.
Engineering note
- For heat exchangers, reserve margin for coil fouling and seasonal high ambient conditions.
- For cabinet cooling, verify both total airflow and local hot-spot temperature around power components.
- For low-noise systems, select a larger fan at lower speed instead of pushing a smaller fan near maximum speed.
