Multifan Galvanized Cone Fan Poultry R

Improve performance by around 10% thanks to the cone

Galvanized Box Fans can optionally be equipped with a cone. This cone reduces air resistance, enabling Galvanized Cone Fans to move up to 10% more air. This enables you to get the most out of your fan.

  • Improved performance
  • Easy mounting
  • Optional butterfly shutter
Light trap

Control daylight hours with light traps

In order to obtain optimal breeding performance both light intensity and the daily amount of light hours must be precisely controlled. That’s why Light Traps are often used in Poultry Houses. The vertical vanes in a Light Trap reduce the daylight ingress and assure an ultimate balance between airflow efficiency and light lux



Multifan Rat Deflector

Optionally available: Set of Rat Deflectors

In some regions, animals such as rats and snakes may enter the livestock house through the Galvanized Box Fan. When these come into contact with rotating parts, there is a high risk of damage to the fan. In order to prevent this, we offer a set of 4 Rat Deflectors. These can be easily attached to the corners of a Multifan Galvanized Box Fan. A small investment to prevent future failures. Please contact our customer support for more information.
