As technical devices become increasingly miniaturized, the demand is growing for efficient, high-quality fans with high static pressure and compact, ultra-quiet multi-blade blowers.
The new D1225R series of cost-effective, ball-bearing-mounted axial fans is available in versions for 12 or 24 V DC. They feature a unique design with optimized impeller shapes and a 3-phase BLDC motor with integrated rubber damping and a new driver IC. The D1225R series therefore offers outstanding features, including a noise level reduced by 5 dB and, with an installation depth of just 25 mm, an airflow performance currently found only in fans with a 32 mm installation depth. The 7 mm saved allows designers to reduce the air resistance of the entire unit, thereby increasing the airflow rate and improving cooling efficiency. This newly developed high-efficiency motor, combined with a new, custom driver IC, has resulted in energy savings of approximately 30 percent.

Comprehensive optimizations

The low-noise operating range has been expanded by 50 percent, while vibrations have been significantly reduced. Thanks to improved energy efficiency, energy savings of up to 30 percent can be achieved. The new design also ensures optimized noise reduction.
For additional functionality, the fans are available with an integrated speed sensor or stall sensor. Furthermore, dust- and water-tight versions are available up to protection class IP68.

Compact 25-mm axial fans

Other new axial fans offer powerful and compact solutions for a variety of applications.
Examples of compact 25 mm axial fans include the D1225R24BBAZ-00, the DS09225024M0001S, and the DS0923224H0011A. The D1225R24BBAZ-00 is a 24V DC axial fan measuring 120 x 25 mm, with a current draw of 0.58 A, an airflow of 150 CFM, and a maximum noise level of 50 dB. Thanks to its IP68 protection rating, it is dustproof and waterproof. The DS09225024M0001S features a compact design measuring 92 x 25 mm, a current draw of 0.22 A, and an airflow of 75.6 CFM at a noise level of 48 dB. For applications with higher requirements for moisture resistance, the DS0923224H0011A is suitable thanks to its IP67 protection rating. It measures 92 x 32 mm, has a current consumption of 0.6 A, and delivers an airflow of 106.37 CFM (0.71-inch H₂O) at a sound level of 51.9 dB.
