Prices & Options
The Helios Fans RRK 250 is a high-performance centrifugal fan engineered for direct in-line installation within circular duct systems. Its casing is constructed from impact-resistant polymer, designed with standard-sized spigots for easy and secure duct connections.
Equipped with a backward-curved centrifugal impeller made from durable polymer, the fan ensures high efficiency and quiet operation. The impeller is dynamically balanced to class G 6.3 as per DIN and ISO 1940 standards, minimizing vibration and ensuring smooth airflow.
Driven by a single-phase external rotor motor, the RRK 250 features integrated thermal contacts wired in series with the windings for overload protection. The motor is maintenance-free, enclosed for protection, and fitted with low-noise, sealed-for-life ball bearings — ideal for long-lasting, reliable operation in ventilation systems.
