With the continuous improvement of product requirements, clean room is awareness and understanding by people. Cost of clean lean room is higher than the normal factory workshop, clean room is also more complex. Therefore, it is very important to maintain the cleanliness of clean room. For now we listed several point for reference:

1, depending on the level of purification differentiate clean area, clean area with cleaner in the boundary area should maintain a high exhaust velocity.

2, the air supply system using multi-stage filtration, the early effect filters used in air conditioning and ventilation systems pre-filter, mainly used for filtering and above 5um particle size of dust particles. Efficiency air filter is in the early effect under a filtration system filters, domestic non-woven bag is generally used air filters, are not commonly used grade HEPA and ULPA filtration efficiency air filters to ensure cleanliness. The air filter is formed on the airflow resistance, the resistance when the resistance exceeded the design, the filter must be discarded and replaced.

3, there is also must say cleanroom airflow, is to determine the correct airflow cleanroom efficiency is the key factor, there are two different flow, one-way flow, also known as laminar flow, and the other non- unidirectional flow, also known as turbulence. Is widely used is unidirectional vertical airflow, HEPA and ULPA air from the ceiling into the air filter, and then from the floor and walls of the exhaust discharge port.

4, clean room staff training, proper use of clean rooms. Entering the clean room clean room needs to be replaced special clothing (clean clothes), but also the air blowing leaching of the air shower room, shower room in the wind put sticky mat also ensures the foot of dirt sticking out. Goods entering the clean room air shower to go through the transfer window will be attached cargo shower of dust particles blowing leaching clean. Do staff members in the personal hygiene and proper manners to regulate.

5, to ensure the necessary pressure, normal pressure in the clean room of the room to be higher than normal pressure, so that it is not contaminated outside intrusion, guaranteed 10-15PA the pressure is reasonable. Pressure is less than 5PA meaningless, because it is difficult to prevent air reflow, high pressure over the General Assembly in the gas stream through different gaps or other leaks will produce noise.

6, regular maintenance and testing of cleanroom.
