    Now there are many laboratories are using the air purification program, that is, we often say sterile laboratory, this laboratory generally needs to use the air shower room.

 Must the sterile laboratory have an air shower? 

    Entering the sterile laboratory must be strictly through the air shower flushing channel. Because the human is a huge biological material, therefore, sterile laboratory to implement strict personnel and physical evidence separation." For this reason, in order to prevent contamination from irrelevant personnel entering the laboratory, a set of fingerprint access control system is set at the door of the sterile laboratory. In addition, the floor of the laboratory door is also laid with sticky mat, before entering the laboratory, feet step on the sticky mat can stick to the dust on the shoes and then enter the air shower buffer channel.

 Sterile laboratory requirements: 

1. The velocity at the air supply outlet in the dressing room and operation room of the purification room is ≥ 0.3m/s, the air speed in the air shower room is ≥ 15m/s, the static pressure difference between the operation room and the environment of the purification room is ≥5Pa, and the system noise is ≤60dB.

2. The second-level (P2) aseptic room is 10,000 grade and local 100 grade, which conforms to the current universal American federal 209E standard.

3. The secondary asepsis room includes high, medium and primary effect filter system, small central air conditioning system, laminar air supply and well return air. The body automatic induction system is adopted in the dressing room and air shower room.

4. In addition to the characteristics of the secondary aseptic room, the third-level (P3) aseptic laboratory also specially sets up electronic interlocking doors, interlocking of transfer Windows and doors, epoxy resin self-leveling ground and water disinfection facilities.

5. The secondary biosafety cabinet is configured. The laboratory and buffer room are both negative pressure Spaces. The relative pressure of the experiment room is -30Pa to -40Pa, and the relative pressure of the buffer room of the purification room is -15Pa to -20Pa.

 The role of the air shower in the laboratory: 

    The main purpose of using the air shower is to ensure the isolation of the laboratory and the outside world. Air shower room can effectively solve the laboratory buffer scheme: air shower room is one of the best purification equipment into the laboratory buffer. It uses high-speed air to blow off and remove particles attached to the surface of clothing or materials. Prevent the staff to bring hair, dust, bacteria into the laboratory, to meet the strict dust-free purification standards of the work site.
