PWM* / E* goes to high, the Drive goes after a short time into the quiescent current mode. When the enable pin PWM* / E* is driven low, the Drive goes to full speed after the initialization of the electronics. This mode can be used if the CCU which controls the Drive has limited capabilities or does not even exist.

“Using a puller fan is seen as a better practice,” says Brent Chuck, application engineer at SPAL USA. “Mounting the fan in front of the radiator adds a restriction to airflow through the system. So, it’s seen as a better practice to put the fan on the engine side and add the restriction after the radiator. When the fan is mounted as a pusher, it b...
Another thing to consider is blade design. SPAL has various blade designs to choose from (straight, curved, and paddle), and each has an operational parameter. “Usually, people have the best results from the thicker fans and the thicker fan blades,” says Brent. “I typically recommend fans like our part number 30102082 with a curved-paddle blade. Th...
Performance:
1. The curved-paddle blade is the best for performance but is a thicker fan requiring more room. 2. The straight blade is the next option in regard to performance. 3. The curved S-blade does not perform as well as the others.
Noise:
1. The straight-blade fan is the loudest. 2. The curved S-blade delivers improved noise reduction. 3. A paddle blade is the quietest. The blade design is more aggressive, so it makes more of a wind sound versus a whining sound like the others. “Basically, we always recommend paddle blades if you can fit them,” says Brent. “They offer the best noise/performance. The other two designs are simply made to be thin, so they make a less desirable noise.”
Finally, electric fans are rated according to the amount of air that can be pushed or pulled through the radiator. This is measured in cubic-feet-per-minute (cfm). In order to find the fan that will work best for your needs, you first need to determine the ideal amount of airflow required to meet your cooling capacity. As a guideline, a typical sma...
