Cylindrical ventilation cowl without base serves for creation of additional draught in ventilation ducts and protects them from unfavourable weather conditions, strengthens natural draught in ventilation duct. Significantly increases the efficiency of the ventilation system. It is the most attractive from the aesthetic point of view. Works without a power source, using wind energy.
Ventilation cowl is installed on the pipe at the upper point of the exhaust duct.
Ventilation efficiency can be increased by up to 20%!

The cylindrical deflector has a smaller radius than the spherical deflector, which provides a more compact arrangement when installing several deflectors in a row.

The cylindrical ventilation cowl without base is made of stainless steel.
It is equipped with additional rotating elements - turbine head and blades. The blades are made of light metals.
The rotation mechanism uses a bearing that makes the blades rotate even in low wind flow.

Information:

• bearings running in oil in a stainless steel housing;

• without a base;

• bases, adapters and mounting pins must be ordered separately;

• very quiet and durable operation;

• maintains draught;

• protects against atmospheric precipitation;

• for ventilation channels;

• housing made of 0.6 mm thick acid-resistant sheet metal;

• turbine made of acid-resistant sheet metal 0,6 mm thick.
   

Due to our own manufacturing facilities, we manufacture mounting plates (bases) and adapters precisely to the customer's requirements - taking into account all technical features.
