High efficiency air filter device air handling unit
(HEPA filter device) is a ventilation filter device specially used in the field of biological safety. It is equipped with a high-efficiency air filter (hereinafter referred to as HEPA filter) and incorporates a design that conforms to the concept of biological safety. One of the important secondary protective barriers, which can effectively prevent the leakage of bioaerosol in the laboratory to the outdoor environment. The 2003 SARS epidemic and the laboratory-acquired SARS infection incident in 2004 exposed the shortcomings of the construction of biosafety laboratories in my country, and attracted great attention from the whole society and government departments. In 2004, GB 19489-2004 "General Requirements for Laboratory Biosafety" was officially released, marking that my country's biosafety laboratory construction, operation and management have entered a standardized and scientific development path. GB 19489-2008 "General Requirements for Laboratory Biosafety" focuses on revising the requirements for exhaust HEPA filters. At that time, my country had not realized the localization of related technologies and products. This content revision effectively promoted the research and development of HEPA filter devices and related technologies in my country.
The air-cooled/water-cooled direct expansion frequency conversion clean air conditioner produced by Guangdong Head-Power Air Conditioning Co., Ltd. is widely used in various levels of biological laboratories, isolation wards, ventilator production workshops, mask production clean workshops, and the unit can be adjusted with constant temperature and humidity, and temperature accuracy With high humidity accuracy, DC inverter compressor is selected, and the refrigeration capacity is variable-frequency stepless adjustment.
