What Is an ATEX FDS_EX Rectangular Fire Damper?

An ATEX fire damper is a passive fire-protection component installed within ventilation ductwork where the duct passes through fire-rated walls, floors, partitions, or compartment boundaries.

During normal ventilation operation, the damper blade remains open and allows air to pass through the duct. When a fire condition activates the damper, the blade closes and helps maintain the integrity of the fire compartment by restricting the movement of fire, hot gases, and smoke through the HVAC duct.

The FDS_EX version adds construction features suitable for potentially explosive atmospheres. The product is designed for gas and dust explosive environments, while its manual mechanism uses conductive plastic to reduce the possibility of mechanically generated sparking.

Key Features of the Explosion Proof Fire Damper

The Explosion Proof Fire Damper combines certified fire resistance, low leakage, hazardous-area suitability, inspection access, and manual or actuator-based closing arrangements.

• Fire resistance up to EI120S: Approved installation arrangements can provide fire resistance for up to 120 minutes, including integrity, insulation, and smoke-leakage performance.
• Gas and dust hazardous-area suitability: The FDS_EX configuration is designed for potentially explosive environments containing both gas and combustible dust.
• ATEX Group II Category 2G and 2D: The damper is classified for demanding industrial gas and dust applications under the ATEX equipment categorisation.
• IIB gas-group protection: The hazardous-area design addresses ignition risks associated with explosion group IIB gases.
• IIIB dust-group protection: The damper is also designed against ignition hazards involving IIIB combustible-dust atmospheres.
• Spark-resistant manual mechanism: Conductive plastic is used in the manually operated mechanism to help minimise the possibility of mechanically generated sparks.
• Tightness class 3C: The damper provides 3C casing/blade leakage performance as standard, exceeding the basic tightness requirement of the harmonised fire-damper standard.
• Integrated inspection openings: Rectangular units larger than 200 × 200 mm are supplied with two inspection openings for servicing and internal examination.

How Does the Ex Proof Fire Damper Work?

The Ex Proof Fire Damper in Dubai forms part of a building’s passive fire-compartmentation strategy.

Its operating sequence is straightforward:

1. During normal HVAC operation, the fire damper remains open.
2. Supply or extract air passes normally through the rectangular duct.
3. A fire or high-temperature condition activates the damper mechanism.
4. The spring or actuator mechanism drives the fire-resistant blade toward the closed position.
5. The blade closes across the duct opening.
6. Fire, hot gases, and smoke are restricted from passing into the neighbouring fire compartment.
7. The surrounding wall or floor construction and the damper installation work together to maintain the required EI or EIS fire-resistance rating.
8. After an incident or test, authorised personnel inspect and reset or service the mechanism according to the installation requirements.

The damper itself is therefore only one part of the complete fire-resistant penetration. The tested wall, floor, fixing method, sealing system, damper orientation, and installation arrangement all contribute to the declared fire classification.

Fire Resistance – EI90S and EI120S

The FDS family has assessed performance configurations including:

• EI90S
• EI120S

The fire classification letters describe several important performance characteristics:

• E – Integrity: The damper prevents flames and hot gases from passing through the fire compartment for the declared period.
• I – Insulation: The assembly limits heat transfer through the fire-separating construction.
• S – Smoke leakage: The damper controls smoke leakage through the closed duct penetration.
• 90 / 120: The number identifies the declared fire-resistance duration in minutes for the applicable tested installation.

The FDS handbook lists EI90(ve ho i↔o)S and EI120(ve ho i↔o)S classifications for relevant configurations, including EX subgroups.

ATEX Gas and Dust Protection

The FDS_EX is not simply a standard fire damper with a different label. Its hazardous-area configuration is developed for locations where the ventilation system may operate in a potentially explosive atmosphere.

The product page identifies:

• Equipment Group: II
• Gas Category: 2G
• Dust Category: 2D
• Gas explosion group: IIB
• Dust explosion group: IIIB
• Gas EPL: Gb
• Dust EPL: Db
• Gas temperature class: T6 to T5
• Dust surface-temperature range: approximately T85°C to T100°C, depending on configuration.

This makes the damper suitable for hazardous ventilation projects where both fire compartmentation and control of potential ignition sources form part of the design.

Manual and Actuator Mechanisms

The FDS_EX can use either a manual closing mechanism or actuator-based mechanism, depending on project requirements.

• Manual mechanism: The manually operated version uses specially selected conductive plastic components and is designed to minimise spark generation.
• Actuator mechanism: Motorised configurations can integrate the damper into the building fire-alarm or ventilation-control system.
• Remote activation: Actuated fire dampers can support automatic closure when the fire-safety system sends the appropriate command.
• Position monitoring: Depending on the actuator and system configuration, open/closed status can be monitored by the building management or fire-control system.
• Maintenance testing: Actuated systems allow functional testing as part of scheduled fire-damper inspection programmes.

Tightness Class 3C

The FDS_EX provides tightness class 3C as standard.

Good leakage performance is important because a closed fire damper must not only block direct flame spread; it should also help limit the movement of smoke and hot gases through the duct.

The 3C construction contributes to:

• Improved smoke control.
• Lower leakage through the damper casing.
• Better containment between fire compartments.
• Improved HVAC system tightness during normal operation.
• More consistent performance in fire-rated ventilation installations.

Inspection Openings and Maintenance Access

Inspection access is particularly important because fire dampers remain open for most of their service life and may not operate until a test or genuine emergency occurs.

FDS_EX rectangular dampers with dimensions greater than 200 × 200 mm include two inspection openings.

These openings allow technicians to:

• Inspect the damper blade.
• Check seals.
• Verify the closing mechanism.
• Remove dust and contamination.
• Inspect the internal casing.
• Confirm freedom of blade movement.
• Check fire-resistant components.
• Complete scheduled operational tests.

Fire Damper Construction

The FDS family is designed as a rectangular duct-mounted fire damper for integration into fire-rated ventilation penetrations.

The standard FDS construction uses:

• Galvanised sheet-metal casing
• Fire-resistant damper blade
• Heat-responsive closing mechanism
• Smoke-sealing components
• Fire-resistant / intumescent sealing components
• Manual or actuator operating mechanism
• Duct connection flanges
• Inspection-access points

The handbook confirms that the FDS family is CE-assessed according to EN 15650:2010, with performance evaluated against the applicable fire-resistance requirements.

Applications of the Hazardous Area Fire Damper

The Hazardous Area Fire Damper is suitable for ventilation systems passing through fire compartments in industrial locations where explosive gas or dust atmospheres can occur.

• Oil and gas facilities: ATEX fire dampers support HVAC and ventilation compartmentation in process buildings, utilities, control rooms, compressor areas, and supporting facilities.
• Petrochemical plants: Rectangular dampers help maintain fire compartment boundaries between process, technical, electrical, and occupied spaces.
• Refineries: Fire-rated ventilation penetrations can use ATEX dampers where hydrocarbon vapours may create explosive atmospheres.
• Chemical industries: FDS_EX dampers support process areas handling flammable liquids, gases, solvents, or combustible powders.
• Battery and energy facilities: Hazardous ventilation areas may require both fire compartmentation and ATEX-rated mechanical equipment.
• Paint and coating facilities: Spray, solvent, and mixing areas can require explosion-protected ventilation components.
• Powder-processing industries: The 2D / IIIB dust configuration supports ventilation projects where combustible dust may occur.
• Industrial warehouses: Hazardous material storage buildings may require fire-rated and explosion-protected duct penetrations.

ATEX Fire Damper vs Standard Fire Damper

Although both products provide fire compartmentation, the ATEX version addresses an additional hazard: potential ignition of an explosive atmosphere.

Choose the ATEX FDS_EX where the ventilation system passes through a hazardous area containing flammable gas, vapour, or combustible dust.

Fire Damper vs Smoke Control Damper

Fire dampers and smoke-control dampers perform related but different functions.

• Fire damper: Closes a ventilation duct penetration to preserve the fire resistance of a wall or floor.
• Smoke-control damper: Forms part of an engineered smoke-extraction or smoke-management system and may open or close depending on the fire strategy.
• FDS_EX function: Primarily provides passive fire and smoke compartmentation in hazardous-area ventilation systems.
• System design: The appropriate damper type must match the building’s fire strategy, HVAC arrangement, and smoke-control design.

Selection of Explosion Proof Fire Dampers

Correct selection is essential because the fire classification depends on both the damper and its installation arrangement.

• Determine the required fire rating: Select EI90S, EI120S, or the required classification according to the building’s compartmentation design.
• Confirm wall or floor construction: The selected damper installation must match the tested supporting construction.
• Check hazardous-area classification: Confirm whether the project requires 2G, 2D, or both gas and dust protection.
• Review gas group: Verify that the project’s hazardous gas classification is compatible with IIB.
• Review dust group: Confirm that the combustible-dust classification is compatible with IIIB.
• Choose the mechanism: Select manual or actuator operation according to fire-alarm integration and maintenance requirements.
• Confirm damper dimensions: Match the rectangular duct size and ensure inspection access remains available.
• Review access requirements: Allow sufficient clearance for inspection, testing, reset, actuator service, and blade maintenance.

Installation of the Ex Proof Fire Damper

Fire-damper installation must follow the tested system configuration because the declared EI rating applies to the complete damper and surrounding fire-resistant installation, not the damper alone.

Important installation points include:

• Install at the fire-compartment boundary: Position the damper according to the tested wall, floor, or duct penetration arrangement.
• Use approved installation materials: Fire-resistant sealing and support systems must match the relevant tested configuration.
• Maintain correct orientation: Follow the permitted horizontal or vertical installation arrangement for the selected classification.
• Keep the mechanism accessible: Technicians must be able to reach the actuator or manual closing mechanism.
• Keep inspection openings accessible: Do not hide access covers behind permanent services or building finishes.
• Maintain duct alignment: Avoid mechanical stress or distortion that could prevent free blade movement.
• Connect actuator wiring correctly: Motorised versions must follow both fire-control and hazardous-area electrical requirements.
• Commission the damper: Verify complete opening, automatic closing, blade locking, position indication, and system control before handover.

Inspection and Maintenance

Fire dampers need scheduled testing because they may remain open for long periods before being required to close.

• Inspect the blade: Confirm that the fire-resistant blade is undamaged and free to move.
• Check seals: Inspect smoke and fire-resistant sealing components for damage or deterioration.
• Test the closing mechanism: Verify that the manual or actuator mechanism closes the damper completely.
• Inspect conductive components: Check spark-resistant mechanism components for damage or contamination.
• Check inspection covers: Make sure covers remain correctly fitted after maintenance.
• Remove obstruction: Clean accumulated dust, debris, or foreign material from the damper.
• Check actuator function: Motorised versions should be tested from the fire-control or BMS interface where applicable.
• Document testing: Maintain inspection and functional-test records as part of the building fire-safety programme.
