In brief: Workshops and garages produce exhaust fumes, dust, solvent vapours or moisture. Electrically opened fanlights and continuous rooflights ventilate by switch or time programme, without a ladder, and close automatically when it rains.
Typical uses
- Car workshop: fanlights above the workstations via group switch.
- Joinery and paint area: ventilate regularly; extraction and fire protection are planned separately by the specialist planner.
- Underground and multi-storey car parks: ventilation there is usually regulated by building law – actuators only as specified by the planner.
- Private or commercial garage: bottom-hung windows against damp and odours.
Which actuators are suitable?
For bottom-hung and fanlight windows a Chain actuator again VS-KAis usually enough. For continuous rooflights and heavy flaps there are Rack and pinion actuators such as the VS-ZA 800 with protection class IP65 – useful where dust or moisture occur.
steering
- VS-C24-7A ventilation control unit for up to 7 actuators, with switch and Rain sensor.
- For hall doors and windows within reach: observe closing edges, see crushing point.
Similar solution for larger buildings: Ventilating hall façades. For a quote, send photos and dimensions via the Project enquiry.
Frequently asked questions
Which protection class do I need in a workshop?
Where dust or moisture occur, a higher protection class such as IP65 makes sense. In dry rooms IP32 is usually sufficient. More under protection class IP.
Can I retrofit existing garage windows?
Usually yes, if there is space on the frame for actuator and bracket. Photos and dimensions are enough for an initial assessment.
