AXIAL FANS, MIXED FLOW FANS AND CENTRIFUGAL BLOWERS

LMB is a leading supplier of high quality axial fans, centrifugal blowers and mixed flow fans. Our wide range of products includes small fans for electronic cooling, high performance fans for air conditioning and filtration systems.

All our products are designed and qualified in accordance with aerospace and / or military standards.

LMB fans are proposed for all types of power supplies: DC brushless (12AC induction and DC brush or brushless to 270V), AC 400Hz and variable frequency.

The fans have speed sensors, speed control, failure detection, thermal protection and current limitation.

Typical applications include:

• Airborne radar cooling
• Avionics cooling
• Electronics cooling
• Engine scavenge
• Cabin crew ventilation
• Evaporator and condenser fans
• NBC protection
• Smoke extraction
• FLIR
• Oil cooler
