The air shower fan is an essential piece of equipment in cleanrooms, designed to effectively remove dust and contaminants from personnel before entering controlled environments. This advanced system includes a voice guidance feature that helps users complete the entire cleaning process step by step. The humanized voice prompts create a more comfortable and intuitive experience, ensuring thorough purification. Clean air, filtered through high-efficiency filters, is distributed evenly across the body via rotating nozzles, providing fast and effective dust removal. The system also incorporates both pre-filters and high-efficiency filters for optimal performance.

Despite its importance, many people are still unfamiliar with how air shower fans operate. To meet specific needs, Shangyu Star Equipment Co., Ltd. has developed specialized air shower fans that offer compact design, high airflow, low noise, strong wind pressure, and easy installation. These features make them ideal for various cleanroom applications.

Key Features of the Air Shower Fan:

• Stepping motors used in air shower systems typically have a step angle accuracy of 3-5%, and this error does not accumulate over time.
• The maximum allowable temperature for the stepping motor depends on the demagnetization point of the magnetic material. Most materials can withstand temperatures above 130°C, with some even up to 200°C. Therefore, a surface temperature of 80-90°C is considered normal and safe.
• The torque of the stepping motor decreases as speed increases due to back EMF generated by the inductance of the motor windings. As frequency rises, so does the back EMF, which reduces the motor's torque at higher speeds.
• The air shower stepping motor operates smoothly at low speeds, but if the speed exceeds a certain threshold, it may fail to start and produce a humming sound.
