The inlets with the greatest range!

Big Dutchman’s wall inlets are made of a shock-proof, recyclable, non- deformable and UV-stabilised plastic material. The insulated inlet flap is kept in a closed position by rust-proof steel springs (not applicable for inlets type B/F), thus sealing the building airtight. The inlet flap opens through downward pull. This allows very precise regulation of the inlet opening in each season.

The corresponding control set opens the fresh air inlets either all at once or individually. With the patented advanced inlet control (not applicable for inlets type B/F), a single action at each inlet pre-defines which inlets open first and which open later.

Technical

  • Advanced inlet control creates stable air jets, especially with minimum ventilation
  • Strong tension springs close the insulated and non-deformable inlet flap (integrated profile made of aluminium), so the barn is absolutely airtight
  • Made of a shock-proof, recyclable, non-deformable and UV-stabilised plastic material
  • Patented advanced inlet control
