Fans for Transportation: Vehicles, Rail, Car Parks and Tunnels
Transport equipment uses fans in two ways. On board, fans cool engines, batteries, power electronics and passengers: condenser fans and blowers in bus air conditioners, cooling fans in rail traction converters. In infrastructure, large fans ventilate car parks and road tunnels and control smoke in an emergency.
This section brings together LONGWELL’s guides for vehicles, rail and transport infrastructure.

What matters for mobile equipment
- Supply voltage: vehicles use 12 V or 24 V DC; rail and some special vehicles use other DC or AC supplies.
- Environment: water spray, road dust, vibration and wide temperature ranges. Check the protection rating and operating temperature range of the fan.
- Space and weight: fans must fit compact units and add as little weight as possible.
- Control: brushless DC fans with speed control can match cooling to the load and reduce noise and power draw.

FAQ
What fans are used in bus air conditioning?
Axial condenser fans cool the condenser coil on the roof unit, and centrifugal blowers push air through the evaporator into the passenger area. Many new systems use brushless DC fans.
Can LONGWELL replace an existing vehicle fan?
Yes. LONGWELL can provide replacement candidates for many vehicle condenser fans and blowers. Send the part number, dimensions, voltage and connector; the final model is confirmed by fit and test.
Do you supply fans for rail vehicles?
See the rail technology section for rail applications, and send the requirements for a selection.
