A blower motor is a critical component of a vehicle or machine’s HVAC system. It powers the fan that pushes air through the evaporator or heater core and into the cabin, providing heating, cooling, and ventilation.
Blower motors are used in:
-
Cars and commercial trucks
-
Construction equipment (e.g., excavators, loaders)
-
Agricultural vehicles (tractors, harvesters)
-
Buses, RVs, and industrial machinery
Depending on the system, blower motors can be single-speed, multi-speed, or variable-speed, and may come with or without a fan cage (also called a squirrel cage or blower wheel).
✅ Key Features:
-
⚡ Voltage Options: Available in 12V and 24V
-
🌬️ Airflow: High-efficiency fan for optimal air circulation
-
🔧 Mounting Styles: Flange mount, bracket mount, or stud mount
-
🔁 Rotation Direction: CW or CCW (as per system design)
-
🌐 Durability: Designed for heat, vibration, and dust resistance
-
📦 Fan Included: Available with or without blower wheel (centrifugal type)
-
🎛️ Speed Control: 1, 2, or 3-speed (via switch or resistor)
