To enter the dust-free workshop, we must go through the necessary sterilization channel, this channel is the air shower room that we are going to talk about today. It can be seen that the air shower is an indispensable purification equipment in the dust-free workshop, and it can also be said that it is an essential channel. It has strong versatility and can be used with all clean rooms and clean plants. When staff enter the workshop, they must pass through this equipment. Into the air shower, you will feel the strong clean air, from the rotating nozzle from all directions to the human body, can quickly and effectively, clear the dust and bacteria on the clothes. Because of its indispensable and indispensable role, the air shower can be used in many industries, then the importance of stainless steel air shower and technical indicators, to introduce.

First, stainless steel air shower box and material requirements

1. high-end stainless steel air shower box, inside and outside the wall is generally made of high quality SUS304 stainless steel, thickness ≥ 1.2mm, air shower chassis and floor made of SUS304 stainless steel, the bottom side of the box is made of stainless steel around the edge, the air shower time 0~99s adjustable; Flat head spherical nozzle, the direction of 360° adjustable; Double door and door frame made of 304 stainless steel, embedded laminated glass window, glass is 5MM toughened glass, electronic interlock;

2. The panel splicing of the unit shall be in the direction of airflow; Unit section assembly and connection are tight; No cracks around the wall structure;

3. the air filter installation is smooth and firm, there is no obvious gap between the filter and the frame and the frame and the wall structure, the filter efficiency of the air filter is 0.3 micron particle size up to 99.99%, the position is placed after the fan;

4. door and door frame smooth, firm, no gap, open flexible;

5. When installing the equipment, the bidder shall take measures according to the actual conditions of the construction site, and the possibility of on-site restructuring shall not be excluded. Before the implementation of the site installation, the bidder shall investigate the conformity of the site construction.

Two, stainless steel air shower fan technical requirements

Stepper motor accuracy is 3-5% of the stepping Angle, and does not accumulate. Air Shower Stepper Motor Appearance allowable temperature. The high temperature of the stepper motor in the air shower chamber will first make the magnetic material of the motor demagnetization, which will lead to a decrease in torque and even a loss of step, so the allowable temperature of the motor appearance should depend on the demagnetization point of different magnetic materials of the motor. In general, magnetic material demagnetization points are above 130 degrees Celsius, and some even as high as 200 degrees Celsius, so the stepper motor surface temperature in 80-90 degrees Celsius is completely normal. The torque of the stepper motor of the stainless steel air shower chamber will decrease with the increase of the speed. Stepper motor of air shower room can operate normally at low speed, but if it is higher than a certain speed, it can not be started, and accompanied by howling.
