Material
1. Shell and rotor blades: High-temperature resistant modified PP engineering plastic, anti-aging, resistant to cold and hot cycles, and not prone to deformation or cracking.
2. Motor core: Metal DC motor, pure copper winding, carbon brush structure; metal bearings.
3. Base support: Reinforced PP plastic, equipped with original factory positioning snap-in and installation holes.
The entire set is a double rotor integrated assembly, with the motor in the center, two centrifugal rotor blades on the left and right, not a single-rotor small blower.
Functions
1. Provide air power for the cab air conditioning and heating system, driving the air circulation inside the vehicle.
2. Cold air mode: Inhaled air passes through the evaporator box for cooling and is then sent to the cab to provide cold air.
3. Heating mode: Air passes through the heating small water tank (H4811010006A0) for heating and outputs warm air.
4. Windshield defrosting and dehumidifying: Provides air flow to blow on the front windshield to remove fog.
5. Internal and external air circulation: Cooperates with the air conditioning damper to achieve new air intake or internal circulation inside the vehicle.
Features
1. Integrated double centrifugal impeller assembly, with sufficient air volume, suitable for heavy truck large cabs; 24V DC motor.
2. Pure copper motor windings, wear-resistant carbon brushes, low operating noise, resistant to bumps and vibrations, suitable for harsh working conditions of heavy-duty trucks.
3. High-temperature resistant plastic housing, does not deform in the cab under high-temperature conditions.
4. OE replica at 1:1 scale, installation holes and plug interfaces fully match the original vehicle, direct replacement, no need for modification or cutting.
5. Complete assembly for shipment: motor + left and right wind wheels + outer housing base set.
6. Can be combined with speed control resistors to achieve multi-speed air volume adjustment.
