Vemo V30-03-1785 Interior Blower

Vemo V30-03-1785 Interior Blower

The Vemo V30-03-1785 Interior Blower is a high‑performance, compact air circulation unit designed specifically for automotive interior applications. Engineered by the renowned German manufacturer VEMO, this blower delivers reliable airflow in a variety of vehicle models, including vans, trucks, and passenger cars that lack integrated climate control systems.

Key Design Features

Compact Footprint: The unit measures only 140 mm × 80 mm × 70 mm, making it ideal for tight engine bays and limited interior spaces. Its lightweight construction—just under 1.2 kg—reduces overall vehicle weight, contributing to better fuel efficiency.

Durable Construction: The housing is fabricated from high‑strength aluminum alloy with a corrosion‑resistant anodized finish. This ensures long service life even in harsh operating environments such as dusty or humid conditions.

High Airflow Capacity: Equipped with a 12 mm diameter impeller, the blower can deliver up to 250 CFM (cubic feet per minute) of airflow at maximum speed. This level of performance is sufficient for maintaining cabin comfort in vehicles without built‑in HVAC systems.

Low Noise Operation: The motor incorporates a precision‑balanced rotor and an integrated acoustic damping system, keeping operating noise below 60 dB(A). This quiet operation enhances the overall driving experience.

Electrical Specifications

• Voltage: 12 V DC (standard automotive supply)
• Current Draw: 1.8 A at full speed
• Power Consumption: 21.6 W maximum
• Motor Type: Brushless DC motor with integrated electronic speed controller (ESC)
• Operating Temperature Range: –40 °C to +85 °C

Installation and Compatibility

The Vemo V30-03-1785 is designed for straightforward installation. It features a standard ISO 9001‑compliant mounting bracket that fits most vehicle chassis designs. The unit’s single connector plug aligns with the typical automotive power distribution harness, eliminating the need for additional adapters.

Vehicle Compatibility:

• MERCEDES‑BENZ Sprinter and other VAG platforms
• Chrysler commercial vans
• Various light trucks and SUVs lacking integrated HVAC
• Custom aftermarket installations in classic cars and specialty vehicles

Operational Modes

The blower offers three selectable speed settings—low, medium, and high—controlled via the vehicle’s existing fan switch or a dedicated remote module. The ESC automatically adjusts motor torque to maintain consistent airflow across all speeds.

Reliability and Maintenance

VEMO’s engineering team has incorporated several design elements that reduce maintenance requirements:

• Sealed Bearings: Prevents dust ingress, extending bearing life beyond 10,000 hours.
• Self‑Cleaning Impeller: The impeller geometry minimizes particle accumulation, maintaining airflow efficiency over time.
• Thermal Protection: An internal temperature sensor triggers a shutdown if the motor exceeds safe operating temperatures, protecting both the unit and vehicle electronics.

Applications Beyond Standard Vehicles

The Vemo V30-03-1785’s robust design makes it suitable for non‑automotive uses as well:

• Commercial refrigerated trailers requiring supplemental airflow
• Industrial mobile workstations where space is at a premium
• Custom electric vehicle prototypes that need efficient cabin ventilation without full HVAC systems
