Blower Speed Controller

Blower speed controller – precise control of airflow intensity

Passenger travel comfort and effective windscreen defrosting depend on the ability to adjust the airflow intensity precisely. In the blower speed controller category on the Peterbus.pl marketplace, you will find electronic and electrical components responsible for changing the rotational speed of fans in 24V systems. We offer both conventional wire-wound resistors and modern electronic control modules.

The Peterbus range includes:

• Electronic PWM controllers: Advanced modules enabling stepless, smooth speed control, used in modern coaches with automatic air conditioning.

• Stepped resistors: Traditional resistor units allowing stepped control of blower speeds (e.g. 1–4), featuring a simple design.

• Controllers for brushless motors: Specialist controllers dedicated to modern blowers from Spal, Aurora and EBM-Papst.

• Dedicated parts for specific brands: Controllers suitable for the systems of VDL Bova Futura, Mercedes-Benz Tourismo, Setra (400 and 500 series) and MAN Lion’s Coach.

Our blower controllers and resistors mainly come from the dismantling of original vehicles and are rigorously tested for stable operation under load. We check every electronic module to eliminate the risk of fluctuating speed or a complete lack of response to commands from the control panel. By choosing an original component from our range, you can be sure that the controller cooling system will fit the factory air duct perfectly.

The most common symptom of a faulty controller is that the blower operates only at the highest speed or becomes completely inoperative despite the fan motor working correctly. If you need help selecting the right resistor for your Bova or Mercedes, our specialists can assist you based on the OEM part number or a photo of your module. Choose proven airflow control from Peterbus and restore the full functionality of your bus’s air-conditioning system.
