VV – Turbine Ventilators

E-mail Print PDF
The trade name of the turbine ventilators manufactured by H-tech group is VENTILATOR FANS (VĚTRACÍ VENTILÁTORY - VV).

The operation of the ventilator fan is based on the use of wind power. It consists of a base and a head. The base is adjustable and facilitates simple installation on 0-45° pitched roofs. The diameter of the suction branch is 200, 260, 355 or 400 mm. The head is made up of segments whose specific shape secures maximum efficiency and prevents water from running inside when it rains. The head revolves noiselessly on antifriction bearings. Individual parts are made of stainless steel, aluminium or copper. In some cases, galvanized (zinc-coated) steel is used.
The fan is most effective when installed as high up as possible on the roof and continually exposed to the wind.

The ventilator fan provides aeration of:

  • production shops and warehouses
  • sports halls
  • roof coverings
  • farm buildings
  • bathrooms, kitchens, lavatories
  • housing premises
  • attic premises
The performance parameters were measured according to the Czech standards. Parameters measured in other countries using different methods may vary considerably.

The performance parameters indicated below were measured according to the Czech standards by VVUU Ostrava - Radvanice, and they closely resemble the actual condition.

Turbine ventilators
A unique ventilation system whose operation does not require electricity. It uses an environmentally friendly source of energy – wind – which is completely free of charge and inexhaustible.
Hybrid ventilators
It rotates constantly, providing the minimum exhaustion rate, which makes it dramatically different from conventional turbine ventilators.
Chimney heads
A unique system designed to enhance the chimney effect. It uses an environmentally friendly, natural source of energy – wind – which is completely free of charge and inexhaustible.
