Important information you need to know when you purchase a gas storage cabinet

What is an important indicator! What is dangerous! What is a useless indicator!

What is an important indicator!
The net gas storage cabinet is an important safety protection product, which has two major functions:
* Harmful chemical gases volatilized during storage in the filter cabinet;
* 24 hours to purify indoor air;
Therefore, its function is to continuously remove harmful chemical gases, which will cause long-term harm to the human body. This is equivalent to placing a large purification device indoors to purify the air for 24 hours, thus preventing them from entering the human lungs and causing harm.

The function of filtration efficiency and filter adsorption determines that the filter used must be very efficient and can last for a considerable period of time, such as 1 year. Conversely, if the filter is inefficient, the clean air storage cabinet will circulate the polluted air indoors. As a result, its security features will no longer exist.

The most stringent standard in the world, the NFX 15-211 standard requires that the filtered air does not exceed 1% of the chemical's TWA* back into the room during normal use of the filter. According to the requirements of this standard, the net gas storage cabinet produced by the manufacturer shall be tested by an independent authoritative third-party testing agency and a relevant test report shall be issued.

TWA*: Occupational Hygiene Standard issued by the Ministry of Health of the People's Republic of China (GBZ 2.1-2007), that is, the chemical exposure concentration allowed in the workplace within 8 hours, in mg/m ³ as the unit of measurement.

Technical Support <br> Filtering a wide variety of chemical gas technologies is a very complex technology. For the manufacturer, it must be ensured that the volatilized gases of the stored chemicals can be filtered and the filter can last for a considerable period of time. For the supplier, before the sale of the net gas storage cabinet, a professional safety confirmation process is required. The user must fill in the name of the chemical to be stored, and the manufacturer will judge according to the list of completed chemicals: Whether the stored chemicals can be effectively filtered and the filter can last for a considerable period of time.

According to the questionnaire, at the same time, manufacturers must recommend the most suitable filter model and indicate non-compatible chemicals. Without this safety confirmation process, the purchased gas-storage storage cabinet cannot guarantee true safety.

What is dangerous?
Feel free to adjust the wind speed! ! !
The molecular filter's filtration efficiency for chemical gases is based on activated carbon, and activated carbon can produce effective filtration. A series of technical rules must be followed. One of them is to keep a constant wind flow through the filter, so the wind speed must be set by the manufacturer before the factory leaves the factory. Users should never make adjustments at will. Be wary of the manufacturer of clean air storage cabinets that provide fan regulators. This behavior will undoubtedly affect the filtration efficiency and adsorption capacity of the filter. At the same time, it also shows that the manufacturer is not an expert in the activated carbon filtration industry, and it is impossible to provide a safe air-type storage cabinet!

Automatic saturation alarm for saturation alarms for any chemical operation?
In fact, automatic alarms that detect filter saturation, whether organic or inorganic, simply don't exist! Be wary of the manufacturer that provides the device, strictly speaking, this device does not exist at all! You are going to rely on it to remind you to change the filter, but in fact it won't do anything at all!
Labo ^® by the company to provide trustworthy, reliable filter saturation detector, detecting whether the manual method (with a reactive color beam tube) saturated or automatic alarm (only for operation based organic gas). We will recommend the most appropriate filter saturation detection system based on the experiments to be performed on the user-supplied questionnaire!
What is useless?

Install a temperature and humidity controller in the clean air storage cabinet! ! !

In fact, the temperature and humidity in the clean gas storage cabinet are the same as the temperature and humidity in the laboratory at any time, because the indoor air is used for 24 hours and is recycled in the cabinet, so there is no need for such a clean air type. The temperature and humidity controller is installed in the medicine storage cabinet, and the equipment manufacturer provides such a temperature and humidity controller, which is not useful at all!

in conclusion! Be wary of manufacturers who want to do business at the expense of your health. The shape of the copied product is very simple! But if you want to copy a technology, it will take years of research and development and development!
