Smoke damper S-RA1

Overview
The S-RA1 series circular smoke control dampers are designed for single-compartment smoke control and smoke & heat extraction systems. Actuator-operated (actuator without spring), they enable defined open and closed safety positions and can also supply clean air to fire compartments.

Key features

• Easy installation
• Actuator-operated (no spring return)
• Fire-resistant construction
• Inspection opening included
• Available in multiple sizes

Benefits

• Simplified integration in mechanical or natural smoke and heat extraction systems
• Controlled removal of smoke and toxic gases
• Capability to supply clean air to fire compartments when required
• Multiple actuator and size options to fit system requirements

Standards & Certification
CE conformity in accordance with the EU Construction Products Regulation (CPR). Reference standards and tests: EN 12101-8:2011, EN 1366-10:2011 + A1:2017 and EN 1366-2:2015. Classification reference: EN 13501-4:2016.

Applications

• Single-compartment smoke control dampers for smoke and heat extraction systems
• Situations requiring removal of smoke and toxic gases and/or supply of clean air to fire compartments

Notes
Actuator type: actuator without spring (provides defined open and closed safety positions). The S-RA1 requires an external power supply. Units are offered in multiple sizes to suit installation and system requirements.
