Darco - chimney caps - cylindrical roof ventilator with base

The cylindrical ventilator is a classic and effective permanent base for ventilation or exhaust fumes.

The cylindrical ventilator is a device that uses the kinetic energy of the wind to support the chimney draft. Produces a favorable pressure system conducive to the movement of air in the chimney flue.

Opening canopy up to 100-200 mm in diameter.

Application

• to support gravitational exhaust ventilation and flue gas evacuation (gas)
• when there are air swirls at the chimney outlet caused by its unfavorable location
• with unfavorable terrain configuration, strong and frequent winds (wind zone II and III)
• when there is no stabilized chimney draft or it is too small
