Helm Roof Louvred Ventilator (H-RLV)
- The Helm H-RLV is designed to automatically provide its maximum exhaust area under fire conditions, whilst providing a fully weathered unit in its normally closed position.
- Regular maintenance testing of all automatic smoke & fire release ventilators are required by Municipal Health & Safety regulations.
- These units can be used as natural ventilators but must then incorporate automatic closing devices, i.e. rain detectors.
- Ventilators can be manufactured from Galvanised, Zincalume, Zincal, Aluminium, Stainless steel or Pre-painted material. An embossed finish is also available on request.
