Single flap Venturi Smoke VS1

Ventilation and SHEV in the flat roof area

The single flap VENTURISMOKE VS1 qualifies as a natural smoke and heat exhaust ventilation unit in the flat roof area. The roda single flap ventilator has a hood that opens to an opening angle of 165° in case of fire. A pneumatic cylinder or a 48V linear drive is used to drive the VENTURISMOKE VS1. In addition to use as a SHEV system, the unit can also be optionally prepared for daily ventilation.
The VENTURISMOKE V1 light, ventilation and fire ventilation system is used in industrial, commercial and municipal buildings. There, the VENTURISMOKE VS1 single flap as a natural smoke and heat exhaust ventilation unit with ventilation function and PC flap infill provides:

Natural daylight
Natural ventilation
Automatic fire ventilation with smoke and heat exhaust ventilation
Energy savings (thermal insulation)

The ventilation and fire ventilation system uses the thermal load within a building depending on the pressure or temperature difference for natural ventilation or fire ventilation and thus to relieve heat and smoke. With weather-dependent daily ventilation, the unit can be closed automatically in the event of rain by means of rain sensor control, thus preventing the ingress of moisture. In case of fire, the hoods are opened after the fire detection element has been triggered.

The single flap VENTURISMOKE VS1 is an EN approved natural smoke and heat exhaust ventilation unit and complies with the requirements of DIN EN 12101-2.

Technical details of the product

Single flap Venturi Smoke VS1

Designs

In the pneumatic design, the ventilation function is achieved by lifting the hoods with a 230V electric motor opener and a stroke of 300 mm. The electric design with 48V drive headbar offers the possibility to individually adjust the opening position for the ventilation. For the fire ventilation of the pneumatic and electric 48V design, the overlap in the end position of the hood is necessary.

Fall-through protection grating

Falls through an opening in the hall roof are not uncommon and often end fatally. According to the BG BAU, around half of all fatal accidents at work are fall-related. The fall-through protection of NSHEVs and skylights must be guaranteed not only during installation but also afterwards if maintenance work is to be carried out on open devices.

Ensuring the required fall-through safety
Maximum size: 1300 x 2500 mm
Mesh width: 100 x 100 mm
