The simultaneous use of opening systems for ventilation and for natural smoke and heat exhaust is possible.


Type of Opening Drive

Manual Opening

The simplest and cheapest opening system. Independent use is suitable solely for ventilation needs. It is used where the height from the floor to the skylight does not exceed 5m. It consists of a telescopic spindle and handle. 

Electrical Opening

For ventilation needs, electric motors with 230V and 24V voltage are used, which standardly enable the lateral raising of the skylight to various heights (standardly from the height of 300mm to 1000mm). Opening with electric motor opening mechanisms is available in different versions. 

The selection of the type of electric motor depends on:

  • the purpose of the skylights – ventilation, natural smoke and heat exhaust,
  • the dimensions of the skylights – with regard to the weight of the skylights and their load-bearing capacity.

Pneumatic Opening

Pneumatic opening is especially suitable for rooms with high specific humidity and filth, because electrical opening is harder to perform under such conditions. It is mostly used in rooms that contain compressed air, because in order to perform pneumatic opening one needs the supply of compressed air from 4–8 bars (primary installation). 

Pneumatic cylinders are standardly used for pneumatic opening. If several skylights for ventilation are installed on the same building, each skylight can be opened separately or several skylights can be opened simultaneously.
Pneumatic opening is suitable for ventilation; it can also be combined with a mechanism for smoke and heat exhaust in case of fire.
