SurgicaL 5000M3/H Ahu Indoor Units Clean Room Air Handling Units

According to the clean operating room design specifications, the clean air conditioning system must have core technical indicators such as constant temperature, constant humidity, fresh air treatment, air purification, and ensuring the positive and negative pressure difference in the controlled area to achieve the design requirements for controlling the concentration of bacteria and reducing the risk of infection. Clean air conditioners have multiple functions such as air purification, transportation, cooling, dehumidification, humidification, heating, heat recovery, and intelligent control, providing users with clean environment system solutions suitable for different purification levels and different working conditions.
