In response to the requirements of some customers for the air volume and heat dissipation effect of DC micro blowers, our company has manufactured a higher flow 18 * 18 * 4mm blower by modifying the magnetic field strength based on BA1804L05. The detailed comparison parameters are as follows:
| Model | BA1804H05 (new） | BA1804L05 （old） |
| Voltage | 5V | 5V |
| Current | 0.08A | 0.04A |
| Air Flow | 0.4CFM | 0.2CFM |
| Air Pressure | 9mmH2O | 6mmH2O |
| Noise | 36.5 dB | 21 dB |
