Helios RDD 200/4 EX

The Helios RDD 200/4 EX is a powerful radial roof fan specifically designed for use in explosive environments. With a rated voltage of 400 V and a power consumption of only 0.08 kW, this fan offers an efficient solution for ventilation. The seawater-resistant aluminum housing ensures durability and resilience, while the newly developed high-performance radial impeller with backward-curved blades allows for a high air delivery rate of up to 610 m³/h. The fan is suitable for operation in a temperature range of -20 to 40 °C and meets the requirements of protection class IP44. With a nominal duct diameter of 200 mm, it is versatile and can be easily integrated into existing systems. The explosion-proof design according to ATEX ensures additional safety in sensitive environments.
