- Heating Coverage: Intended for areas around 215–269 ft² depending on insulation and ambient temperature.
- Controls: Bluetooth app control for remote start and temperature adjustment plus a physical remote and LCD.
- Altitude Compensation: Automatic adjustment up to 18,045 ft to maintain combustion stability.
- Construction: Sandblasted aluminum heat exchanger for improved heat transfer and durability.
High-power units like this require careful installation planning: fuel supply, exhaust routing, and electrical wiring must meet ventilation and safety guidelines. Consider noise and mounting location to reduce vibration transfer into the vehicle cabin.
12V 2KW Blower Motor Assembly For Airtronic D2
This 12V blower assembly is tailored for 2KW Webasto/Eberspächer Airtronic D2 parking heaters. It emphasizes low noise, low power consumption, and durable PVC/iron materials that resist wear and elevated temperatures.
- Application: Replacement blower assembly for 2KW parking heaters.
- Voltage: 12V DC operation aligned with common vehicle electrical systems.
- Build: Wear-resistant components intended for extended heater cycles and repeated starts.
When replacing blower assemblies in Airtronic or Webasto systems, check part numbers against OEM references. Proper match avoids airflow mismatch that could affect combustion or interior heating distribution.
Buying Guide: Choosing The Right Diesel Blower Heater
This buying guide highlights the factors to weigh when selecting a diesel blower heater or blower motor replacement. Consider environment, compatibility, installation, and safety to match product capabilities to your needs.
Heat Output And Coverage
BTU or kW Rating: Match heater output to the space volume and insulation. Small cabins or seats may be satisfied by 2KW units, while larger vans, garages, or workshops typically require 5–8KW systems.
Practical Coverage: Manufacturer coverage estimates assume specific insulation. For uninsulated garages, choose higher capacity or supplemental heating.
Blower Motor Compatibility
Model Fit: Replacement blower motors must match mounting pattern, shaft size, connector type, and airflow direction. Confirm OEM part numbers or compare physical dimensions before buying.
Voltage: Ensure the blower matches system voltage — most automotive parking heaters use 12V, some commercial setups use 24V.
Power Source And Controls
Electrical Options: All-in-one heaters with 110V transformers allow plug-in operation without vehicle battery reliance. For mobile use, verify DC draw and fuse protection.
Control Interface: Consider units with app control, remote, or LCD interfaces for preheating and temperature management. Simpler toggle switches may suffice for basic needs.
Altitude And Cold-Start Performance
If you operate at high elevations or extreme cold, choose heaters with altitude compensation and low-temperature start ratings. Altitude sensors or automatic compensation prevents combustion instability and reduces stall risk.
Materials, Durability, And Noise
Construction: Aluminum heat exchangers and metal combustion chambers offer improved durability and heat transfer. Plastic housings can reduce cost but verify temperature tolerance.
Noise: Blower and pump noise varies by design. Check product notes on low-noise operation if cabin quietness matters.
Safety And Emissions
Exhaust Routing: Proper exhaust and fresh-air intake routing is mandatory to prevent CO buildup. Some modern units include CO detection or shutoff systems—consider these when safety is a priority.
Fuel Handling: Verify leak-proof fuel caps, quality fuel lines, and secure mounts. Improper fuel handling creates fire and vapor risk.
Installation Considerations
Mounting Space: Measure available mounting locations for heater body and ducting. Compact units fit under seats; larger units may need floor or engine compartment mounting.
Venting And Ducting: Plan exhaust and fresh-air piping with appropriate clearances and heat shielding. Also plan interior ducting so heated air distributes efficiently.
Maintenance And Serviceability
Spare Parts Availability: Choose brands or designs with accessible replacement blower motors, fuel pumps, and control modules. Regular service items include glow plugs, filters, and blower fans.
Ease Of Service: Modular designs and documented service manuals simplify repairs and reduce downtime.
Control And Automation Options
Select additional control features based on usage patterns: timers for scheduled preheating, thermostats for automatic temperature hold, and app-based control for remote starts. Balance convenience with installation complexity.
Comparison Perspectives
- Replacement Motor vs. Complete Heater: Replacement blower motors are cost-effective when the combustion system remains sound. Complete heaters provide integrated systems when you need both combustion and airflow replaced.
- Low-Power vs. High-Power Units: Low-power heaters reduce fuel use and can be quieter, but may struggle in poorly insulated areas. High-power units deliver faster warm-up and broader coverage but need more careful installation and fuel management.
- OEM vs. Aftermarket: OEM brands (Eberspächer, Webasto) emphasize certified performance and service networks. Aftermarket units may offer features like Bluetooth or CO alarms at lower cost; verify build quality and warranty terms.
Use the compatibility checklist—voltage, physical mounting, connector type, exhaust routing, and control interface—to narrow choices before purchase. For vehicle installations, follow local regulations and manufacturer installation best practices to ensure safety and reliable operation.
