Roof centrifugal fan ERF 280

Efficient air extraction with reliable roof-mounted design

The roof centrifugal fan ERF 280 is designed for air extraction in the ventilation of residential and commercial buildings. It is suitable for removing polluted air and other non-flammable air mixtures where reliable airflow, stable pressure, and robust construction are important.

Main advantages

• High airflow
  With a capacity of 1550 m3/h, it effectively helps extract air from the room or ventilation system.
• Reliable operation under load
  A pressure of 780 Pa allows use where stronger discharge through the ventilation system is required.
• Protection for more demanding conditions
  The metal with IP 54 protection offers resistance to dust and water splashing, which increases safe use.
• Robust construction
  The galvanized steel housing ensures a solid and durable design.
• Safer operation
  Automatic restart after overheating helps protect the motor and continue operation after a temporary interruption.

Installation and operation

The fan is intended for roof mounting in a horizontal position, with the motor shaft installed vertically. Installation is carried out on a mounting base or on the roof outlet of the ventilation shaft. This design allows for a clear and functional integration into the roof ventilation system.
