The first product to introduce positive pressure respirator technology into medical protection, providing medical personnel with a higher level of protection, especially during the epidemic, the hood is made of medical protective clothing material to control the microbial limit and avoid pollution of the medical environment. Suitable for medical staff to wear for a long time. The disposable hood design reduces cross infection of skin diseases caused by long-term wear by medical staff. The imported brushless motor has strong air volume, low power consumption, long service life and long-term operation. The fan uses a streamlined vortex air duct, high static pressure and low noise, which reduces the exhaust noise and does not lose suction. Intelligent control, stable airflow, can automatically adjust the power according to the degree of blockage of the passage, provide a stable and clean air supply, let users enjoy healthy breathing freely. Real-time monitoring and display of battery power, when the blockage is serious or the power is too low, dual alarms of sound and vibration are provided. Multi-layer filtration setting, particle filtration efficiency up to 99.995%. The basic form of the appearance comes from the hexagons in the chemical structure diagram of the polymer compound. A combination of multiple hexagons constitutes a mysterious biological science with strong industry attributes. This product can provide a protection factor (APF) from 25 to 1,000. The APF of N95 is 10, which provides a higher level of protection compared to N95. The positive pressure in this hood can provide splash protection and a certain degree of eye protection, which largely guarantees a high level of protection, does not require suitability testing, and does not need to consider facial hair or other factors to affect the sealing effect. The air flow protects the shield from fogging and reduces heat accumulation. Lightweight and portable, the battery can be used for more than 6 hours.
