Explosion-Proof Fans
Explosion-Proof Fans — selection guide
Explosion-Proof Fans: 31 models, maximum airflow 220–18,000 m³/h, AC motors, across 5 series.
Explosion-proof fans for hazardous areas: LWEX-AF axial fans, LWEX-WF and LWEX-WFS wall fans, LWWEX-OR external-rotor wall fans and the LWSFPEX portable safe-area axial unit, 220 to 18,000 m³/h with 70–1,100 W motors on 220 / 380 V. Motors and construction are matched to the zone and gas group of the installation and certified per configuration.
How to select from this range
- Define the hazardous-area zone and gas / dust group first; it fixes the motor protection concept and materials.
- Select the duty point as for any fan, then confirm the Ex rating with our engineers — certificates are issued per configuration.
- Specify spark-resistant construction (AMCA 99 type A / B / C) where the application requires it.
Where these fans are used
- Oil & gas facilities
- Chemical and pharmaceutical plants
- Paint booths and solvent stores
- Battery and hydrogen facilities
Every figure above is measured on our own test rigs per AMCA 210 / ISO 5801 methods — see the test labs and certificates. Final selection is confirmed at the duty point and by project validation.
