- ATEX Certified Explosion-Proof Design – Manufactured to comply with ATEX and European safety standards including EN 50014, EN 50019, EN 1127-1, and EN 13463-1, making it suitable for hazardous environments with explosive atmospheres.
- High Airflow Performance – Equipped with a forward-curved impeller and external rotor motor that delivers airflow up to approximately 3175 m³/h (0.778 m³/s), ensuring effective ventilation and air extraction in industrial spaces.
- Durable Industrial Construction – Built with a galvanised sheet steel casing and copper inlet cone, providing excellent durability, corrosion resistance, and long service life in demanding environments.
- Motor Protection & Speed Control – Features integral thermistors (PTC) to protect the motor from overheating and supports speed control functionality, allowing adjustable airflow depending on ventilation requirements.
- Flexible Installation – Compact rectangular duct design allows the fan to be installed in multiple positions, making it suitable for duct systems in battery rooms, fume cupboards, workshops, and industrial ventilation systems.
The Systemair DKEX 280-4 ATEX Rectangular Duct Fan is a high-performance industrial ventilation solution designed for hazardous environments where explosive gases or vapors may be present. Built with a durable galvanized steel casing and a copper inlet cone, this explosion-proof fan ensures reliable airflow while maintaining strict ATEX safety compliance. The fan features a forward-curved impeller and an efficient external rotor motor, delivering powerful airflow up to approximately 3175 m³/h while maintaining stable and quiet operation. Integrated thermistors (PTC) protect the motor from overheating and must be connected to a compatible motor protection relay for safe operation. Suitable for installation in various positions due to its compact rectangular design, the DKEX 280-4 is ideal for battery charging rooms, fume cupboards, and other industrial environments requiring safe and efficient air extraction.
