A vehicle blower and dryer should have sufficient power to effectively remove water and debris from the vehicle's surface without causing damage. The power of a blower is typically measured in terms of airspeed (miles per hour or kilometers per hour) and air volume (cubic feet per minute or CFM).
For a vehicle blower, an airspeed of at least 150 mph (240 km/h) is generally recommended to ensure efficient water removal. This speed is adequate to displace water from crevices, mirrors, and other hard-to-reach areas. Higher airspeeds, such as 200 mph (320 km/h) or more, can provide even better performance, especially for larger vehicles or those with intricate designs.
In terms of air volume, a CFM rating of 500 or more is advisable. A higher CFM allows the blower to cover a larger surface area quickly, reducing drying time. Some professional-grade blowers offer CFM ratings exceeding 1,000, which can be beneficial for commercial use or for those who frequently wash multiple vehicles.
The blower should also have a motor power of at least 1.5 to 2 horsepower (HP) to ensure consistent performance. More powerful motors, such as those with 3 HP or more, can enhance efficiency and durability, especially for frequent use.
Additionally, the blower should feature a temperature-controlled airflow to prevent damage to the vehicle's paint and surface. Some models offer heated air, which can accelerate the drying process and improve results.
Ultimately, the ideal power level depends on the specific needs, such as vehicle size, frequency of use, and personal preferences. Balancing airspeed, air volume, and motor power will ensure effective and safe drying of the vehicle.
