High-Powered Motor: Engineered with a single-phase, high-powered external rotor motor. The VKM configuration provides significantly higher airflow rates and pressure handling capabilities compared to standard 315mm inline models.
Industrial-Grade Construction: The fan casing is fabricated from durable steel and protected against corrosion with a premium polymeric coating. This heavy-duty design provides excellent mechanical strength and weather protection, making it fully reliable for both indoor environments and outdoor installations.
Long Service Life: The premium motor features dynamically balanced turbines coupled with backward-curved centrifugal blades and heavy-duty ball bearings. It is rated for a continuous operational life of at least 40,000 hours.
Integrated Safety Measures: Overall housing protection rating of IPX4. The motor includes built-in overheating protection with an automatic restart mechanism to prevent thermal strain during demanding cycles.
Versatile Multi-Angle Installation: The fan can be seamlessly integrated into circular air ducts at any angle. Each unit comes complete with standard outer fastening brackets that allow secure mounting to walls or ceilings.
