High performance for large air volumes and applications requiring efficiency, reliability, and power.
The SFPF EC line of Plenum Fan centrifugal fans features impellers ranging from 355 to 500 mm in diameter and uses an Air Foil-type impeller made of high-strength aluminum. The units feature an ultra-compact housing, direct drive powered by a high-efficiency EC motor, and ball bearings, providing reliable performance and durability.
The line includes models with airflow rates of up to 18,221 m³/h and maximum pressures of up to 246.84 mmWC, depending on the selected model. The fans feature a carbon steel support and inlet nozzle, IP54 protection rating, Class F insulation, and a 400 V three-phase power supply, with an operating frequency of 50–60 Hz.
The Plenum Fan configuration is suitable for HVAC systems, air handling units (AHUs), air conditioning systems, building ventilation, commercial and industrial refrigeration, ventilation in sustainable buildings, decentralized and modular Fan Wall ventilation units, stairwell pressurization, and other applications.
The SFPF EC line models are suitable for applications requiring large air volumes and can be integrated into different ventilation and air treatment solutions according to each project’s requirements.
The units feature a high-efficiency EC motor, ball bearings, IP54 protection, and Class F insulation. Model selection should take into account the rated data and technical parameters specified in each unit’s tables.
