ATEX Explosion Proof Axial Duct Fan
ATEX Explosion Proof Axial Duct Fan
Blog Article
An ATEX-certified explosion-proof axial duct fan is designed for safe operation in hazardous environments where flammable gases, vapors, or dust may be present. These fans comply with ATEX Directive 2014/34/EU (EU) and IECEx standards (international) for explosive atmospheres.
???? Key Features of ATEX Axial Duct Fans
Explosion-Proof Construction
Housing & Motor: Made of non-sparking materials (e.g., aluminum, stainless steel).
IP Rating: Typically IP55 or higher (dust and water-resistant).
Temperature Class (T-rating): Ensures surface temps won’t ignite gases (e.g., T4 ≤ 135°C).
Certifications
ATEX Zones:
Zone 1 (gas) / Zone 21 (dust) – Explosive atmosphere likely.
Zone 2 (gas) / Zone 22 (dust) – Explosive atmosphere rarely occurs.
Gas Groups: IIA, IIB, or IIC (e.g., methane, ethylene, hydrogen).
Dust Groups: IIIA, IIIB, IIIC (combustible dusts).
Motor & Electrical Protection
Ex d (Flameproof): Contains explosions inside the motor.
Ex e (Increased Safety): Prevents sparks in normal operation.
Voltage: Common options: 230V AC, 400V AC, or 24V DC.
Airflow & Pressure
Flow Rate: Typically 100–10,000 m³/h (varies by size).
Static Pressure: Low to medium (axial fans are less pressurized than centrifugal).
Materials & Design
Blades: Non-sparking (aluminum, plastic, or coated steel).
Sealing: Gaskets prevent gas/dust ingress.
