FAQ

Choose a category

Is the Aerodynamic Free Area available for the SLD?

The aerodynamic area does not apply to dampers or EN12101-8; it is specific to natural smoke vents under EN12101-2.

Do you offer a 1.5m² free area natural vent?

Yes, we can provide our 120.170 SLD, which consists of two 60.170 SLD units.

Where can the actuator be located?

The actuator can be positioned either at the top or the bottom of the SLD.

What is the electrical rating for the SLD?

The standard electrical rating is 24V/0.3A DC, but it can be configured for 230V AC if needed.

Can the SLD be installed in any orientation?

The SLD is certified for vertical installation only and is not approved for horizontal installation.

What is the minimum wall thickness for installation?

The minimum wall thickness required is 125mm for flexible walls.

Can the SLD recess inside the shaft?

Dampers may protrude slightly into the shaft in most cases, but this typically does not pose an issue.
