There are some common faults in the air shower room, such as the power indicator is not connected. If the power supply is cut off on both sides of the cabinet, the power supply can be cut off at several places outside the cabinet, including the power switch on both sides of the cabinet. Single air shower to solve the problem of air shower
The air shower room is composed of large box (fan and filter are installed in the box), small box (the number of nozzles installed on this side of double air shower chamber is the same as that of large box), top plate (installation of embedded lighting), inner bottom plate (stainless steel sand plate), double door of air shower room and other accessories: filter, fan, intelligent circuit board, nozzle, lighting lamp, etc.
According to the introduction of relevant experts, the air shower mainly adopts the air flow form of jet flow. The variable speed centrifugal fan presses the air filtered by the pre filter in the negative pressure box into the static pressure box, and then the clean air flow is blown out through the air outlet surface. When passing through the working area with a certain wind speed, the dust particles and biological particles of people and objects will be taken away, so as to achieve the purpose of cleaning.

If the air shower can not automatically sense the shower, please check the light sensing system at the lower right corner of the box in the air shower room to see if the light sensing device is correctly installed. If the light sensing two sides are opposite and the light sense is normal, the air shower room can automatically sense the shower.
The high-efficiency filter with clapboard is matched with the earlier air shower. Therefore, the manufacturers of air shower will choose the high-efficiency filter without partition board, which has higher technical content and better filtering effect than the high-efficiency filter with partition board.
If the fan in the air shower does not work, the user needs to check whether the emergency switch of the outdoor box of the air shower is cut off. If it is cut off, press it gently with your hand and rotate it to the right to release it.

If the air shower room is used for a period of time when the wind speed is very low, please check whether the primary and high efficiency filters of the air shower room have accumulated too much dust. If so, please replace the filter. "The primary filter in the air shower is generally replaced once in 1-6 months, and the high-efficiency filter in the air shower is generally replaced once in 6-12 months." The manufacturer said. (source: China Pharmaceutical network).
New year's new weather, leaving the heavy burden of moving forward in 2018, a new year of 2019 has been re opened [detailed]!
For pharmaceutical enterprises, the material of air shower room is generally made of stainless steel or color steel plate. The stainless steel material is elegant and beautiful in appearance. It has the characteristics of anti-corrosion, anti-oxidation and no rust, and it is very strong. It is suitable for humid environment or occasions with corrosive gas or liquid, and has a long service life.
In addition, there are many considerations in the selection of air shower room for clean production in pharmaceutical industry, such as whether there is a high-quality high-efficiency filter. Nowadays, we usually choose non clapboard high-efficiency filter, and of course, we can choose high-efficiency filter with clapboard.
Experts suggest that when users choose the air shower room, they usually take 25 people as the basic unit, single person air shower room for less than 25 people, double-edged wind shower room for more than 25 people and less than 50 people, and so on.
If the fan in the air shower room reverses or the wind speed in the air shower room is very small, please make sure to check whether the 380V three-phase four wire circuit is connected reversely. Generally, the manufacturer of the air shower room will have a specially assigned electrician to connect the line when the factory is installed. If the line source of the air shower room is reversed, the light one will cause the fan of the air shower room not to work or the wind speed of the reverse air shower room will decrease, and in the heavy case, the circuit board of the whole air shower room will be burned. It is suggested that the enterprise using the air shower room should not replace the wiring lightly. Single air shower?
The author understands that the air shower room is the channel for the products to enter and exit the clean room, and at the same time plays the role of airlock to seal the clean room, which can prevent the invasion of unclean air and ensure the cleanliness of the clean room.
In 2019, the pharmaceutical industry will also produce a lot of new achievements, and for the development in 2019 [detailed]?
