HEPA Box is the terminal filtration device of Cleanroom air supply system. It's main function is to transport the purified air to the Clean Room with uniform speed and good airflow organisation, to effectively filter the dust particles in the air and to ensure that the air quality in the Clean Room meets the corresponding cleanliness level requirements. For example, in the pharmaceutical workshop, electronic chip manufacturing workshop and other places with very high requirements for environmental cleanliness, HEPA Box are able to provide clean air to meet the production process. For example, in pharmaceutical workshops, electronic chip manufacturing workshops and other places with extremely high demands on environmental cleanliness, HEPA Box can provide clean air to meet the production process.

HEPA filters are mainly used to capture particles below 0.5um and various suspended matters. It adopts ultrafine glass fiber paper as filter material, offset paper, aluminum film and other materials as dividing plate, and is glued with aluminum alloy of wooden frame. Each unit has been tested by Nano-flame method, featuring high filtration efficiency, low resistance and large dust capacity.

For the assembly of electronic products, static hazards seriously affect the quality of the product, yield and reliability, must be used for the assembly of electronic products in the purification room for systematic anti-static measures to minimise the degree of static hazards in the production process.

Static electricity in general is 'difficult to see, and not easy to touch', but it is almost everywhere, all the time, so the electrostatic protection is a comprehensive systematic project, in principle, electrostatic protection should be from the control of static electricity generation and control of static dissipation of two aspects, control of static electricity generation is mainly to control the process and the process of process.
