Safety and Performance Combined: ATEX and CE Certified Explosion Proof Fan Filter Units

In industries where volatile substances, flammable gases, and dust particles are present, safety is not negotiable. Facilities in sectors such as pharmaceuticals, petrochemicals, and electronics must maintain ultra-clean environments while preventing the risk of explosions. This is where ATEX and CE certified explosion proof fan filter units (FFUs) come into play. Engineered to meet the most rigorous European and international standards, these units provide both contamination control and explosion safety, ensuring cleanroom operations remain reliable, compliant, and secure.

A fan filter unit is a self-contained filtration system designed to supply clean, particle-free air to controlled environments. It consists of a fan, a pre-filter, and a high-efficiency HEPA or ULPA filter. When adapted for hazardous areas, explosion proof FFUs are built with specialized enclosures, motors, and electrical components that eliminate ignition risks, even when exposed to flammable atmospheres.

The ATEX certification confirms that the unit complies with European standards for equipment used in explosive environments, while the CE marking ensures conformity with EU safety, health, and environmental protection directives. Together, these certifications guarantee that the FFU is safe, reliable, and globally recognized.

• Enclosed motors, sealed electrical wiring, and anti-static housings.
• Non-sparking fan blades and reinforced structures.
• Compliance with hazardous zone classifications (Zone 1, Zone 2, Zone 21, Zone 22).

• HEPA (H13/H14) or ULPA filters with efficiency up to 99.9995%.
• Pre-filters to extend service life of main filters.
• Uniform airflow distribution for particle-sensitive environments.

• ATEX certification for explosive atmospheres.
• CE certification for European market compliance.
• Designed to meet EN, ISO, and GMP cleanroom guidelines.

• Low-noise, variable-speed motors.
• Intelligent airflow management to optimize energy use.
• Reduced lifecycle costs through durable components.

• Compatible with modular cleanroom ceilings.
• Available in different sizes and airflow capacities.
• Can be configured for single-use or scalable multi-unit integration.

ATEX (ATmosphères EXplosibles) is a European directive ensuring equipment is safe to operate in explosive atmospheres. Certified explosion proof FFUs are tested against ignition risks, including sparks, hot surfaces, and static electricity.

The CE mark ensures the unit complies with health, safety, and environmental standards for the European market. A CE-certified FFU provides assurance of regulatory conformity across multiple sectors.

Together, these certifications give facilities peace of mind that the equipment not only performs effectively but also safeguards lives and property.

Explosion proof FFUs provide safe sterile air for cleanrooms handling volatile solvents and chemicals.

Protects sensitive operations in hazardous atmospheres while maintaining clean air standards.

Prevents static discharge and airborne contamination in sensitive production lines.

Ensures hygienic production environments when combustible dust particles are present.

Supports high-reliability environments where safety and precision are equally critical.

1. Air Intake – Ambient air is drawn into the unit through a pre-filter.
2. Primary Filtration – The fan forces air through HEPA or ULPA filters, removing particles.
3. Explosion-Proof Safeguards – Non-sparking motors and sealed enclosures ensure no ignition risks occur.
4. Clean Air Delivery – Filtered air is supplied uniformly into the cleanroom, creating a safe and contamination-free environment.

• Routine Inspections: Check for wear on fan blades, seals, and electrical connections.
• Filter Replacement: Replace HEPA/ULPA filters according to manufacturer’s service intervals.
• Compliance Testing: Regular airflow velocity and particle count tests to maintain certification standards.
• Operator Training: Ensure personnel are familiar with safety protocols and emergency procedures.

The ATEX and CE certified explosion proof fan filter unit represents a perfect balance of safety, performance, and regulatory compliance. Designed for industries where both clean air and explosion prevention are essential, these systems protect workers, processes, and facilities. By combining reliable filtration technology with rigorous international certification, they provide peace of mind and operational efficiency in the world’s most demanding environments.
