Helios Fans AMD 355÷2÷2

The Helios AMD 355÷2÷2 is a powerful and versatile axial fan engineered for high-performance ventilation in industrial and commercial environments. With a 355mm diameter galvanized steel cylindrical casing and standard DIN 24155 Part 3 flanges, it ensures secure and seamless installation into ducted systems.

This model features a 2‑pole, dual-speed, direct-drive 3‑phase motor, allowing operators to switch between two airflow levels depending on system demands — ideal for applications requiring adjustable ventilation intensity. The motor is maintenance-free, equipped with sealed-for-life ball bearings, integrated thermal protection, and IP54 ingress protection for long-term reliability.

The fan includes a 14-blade polymer impeller, precision-balanced to DIN ISO 1940 – 1 (class 6.3), ensuring quiet, low-vibration operation even at high speeds. It also supports voltage-reduction speed control, offering enhanced adaptability in airflow regulation.

Designed to handle air temperatures up to 40°C (controlled) or 60°C (uncontrolled), the AMD 355÷2÷2 is suitable for HVAC systems, manufacturing facilities, equipment cooling, and other industrial settings where flexible, efficient airflow is essential.

The Helios AMD 355÷2÷2 combines robust construction, dual-speed performance, and quiet operation, making it a smart choice for demanding ventilation scenarios.
