WZD

centrifugal, hybrid fan
WZD is a special design of a roof fan integrated with a gravitational ventilator. WZD fans replace two separate structures requiring two roof openings.

Integrated fan - how does it work?

Integrated fans are used for ventilation of industrial buildings with variable demand for air exchange. This is the so-called two-channel ventilation. The air extraction takes place as follows:
  • internal duct – mechanically by means of a fan
  • external channel – by gravity

Such a ventilation system allows you to ventilate two different rooms with one fan, e.g. connecting a roof fan to the toilet room and a gravitational duct to ventilate the hall. Integrated ventilators can also be used for hybrid ventilation – natural ventilation as basic ventilation and mechanical ventilation as emergency.

Installation directly on the plinth.

As a standard, WZD ventilators are equipped with a B/II type roof base, thanks to which they can be mounted directly on a chimney or plinth. At the customer’s special request, it is possible to make a plinth for a given ventilator, as well as other accessories, i.e. noise silencers, non-return flaps, dampers, etc.
