Purification principle of clean room:

Air flow → initial effect air treatment → air conditioning → medium effect air treatment → fan pressurized air supply → purification air supply pipe → high efficiency air supply outlet → clean room → dust (bacteria) away → return air passage → fresh air, initial effect air treatment. Repeat the above process to achieve the purpose of purification.

Technical parameters:

Ventilation times: 100,000-class 10-15 times/hour;

10-thousand level 15-25 times/hour;

1000 class 50-52 times/hour;

The cross-section wind speed of the 100-class operation platform is 0.25-0.35m/s;

Pressure difference: the main workshop for adjacent clean rooms ≥5Pa; Clean room for non-clean area ≥10Pa; Temperature: > 16℃±2℃ in winter; < 26℃±2℃ in summer;

Relative humidity: 45-65% (RH);

Noise ≤65dB (A);

Fresh air compensate volume: 20%-30% of the total air supply volume;

Illuminance: ≥300Lux.

Structure of the data

1. The wall and roof of the clean room are generally made of 50mm thick sandwich color steel plate and special aluminum oxide profiles for purification. The door selects the purification sealed door, the window selects the aluminum alloy glass fixed window.

2. the ground selection of epoxy self-leveling or high-grade wear-resistant plastic clean floor.

3. The purification ventilation pipe is made of galvanized steel sheet, and the "PEF" flame retardant insulation board is used for insulation.
