Hard-wearing explosion-proof fans for critical applications
Combine maximum safety with maximum flexibility
Certified according to ATEX directive 2014/34/EU
Discharge direction adjustable on site
Low sound level
Safety first
MUB EX fans are designed for challenging environments where explosive atmospheres can occur. Which is why they are tested according to ATEX directive 2014/34/EU – to ensure they’ll perform as intended after installation.
Sturdy and strong
MUB EX fans come with an aluminium frame and impellers, double skin panels manufactured from galvanised steel, shock-resistant corners, and panel rivets. Making them highly resistant to environmental stressors in their specialised applications.
Flexibility
Like all MUB fans, MUB EX fans come with removable panels so the outlet side can be chosen on-site prior to installation. Giving you further flexibility if your plans or requirements change in between ordering and final installation.
Performance
MUB-EX can be used for temperature classes T1, T2 and T3. Exhaust of explosive gases in Zone 1 and Zone 2, and groups IIA and IIB plus hydrogen H² is possible.
