How does Huafeng's pipeline-free gas storage cabinet work?

The top of the clean air storage cabinet comes with a fan and a filter. When the switch is turned on, the fan operates to create a negative pressure inside the cabinet to ensure that the chemical does not overflow. The wind direction of the main body is from bottom to top, so that the air in the cabinet is filtered through the filter, and the clean air is removed from the top exhaust vent. On the one hand, it purifies the chemicals volatilized in the cabinet, and on the other hand, the air in the laboratory enters the cabinet, and the air in the laboratory can also be purified.

Type of filter

The filter is divided into two categories: dust filter and gas filter. The gas filter can again be:

General purpose filter (TY) and organic filter (YJ). The universal filter has strong adsorption capacity for acid gases and can adsorb organic solvents. The organic filter is for organic gases, followed by acid gases.

The characteristics of the net gas storage cabinet

* fan
24 VDC, imported from the United States, stable performance, long-term lubrication, low energy consumption, ultra-quiet, brushless motor, no sparks.
* Molecular filter <br>The high absorption efficiency of coconut shell activated carbon is used as raw material, supplemented by independent research and development of high-capacity adsorption materials, which is superior to similar products on the market and meets domestic and international standards.
* Control panel <br>Oversized LCD screen, the panel has a strong sense of beauty, convenient man-machine dialogue and easy operation. The new invention design shows indoor environmental pollution, filter saturation, 365 days countdown, fan speed, and chemical storage temperature in the cabinet.
* door
New design, aluminum alloy mold opening, no screw sturdy, anti-corrosion coating, high-quality clear acrylic in the middle, full viewing angle of chemical storage location in the cabinet. Built-in hidden permanent magnets, natural door suction.
* Online monitoring concentration probe
The patented design, the concentration inside the liquid crystal display cabinet and the concentration after the filter, are corrected by PID. High sensitivity, high accuracy, on-line monitoring, manual detection, humanized design, alarm concentration according to national standards, manual modification of alarm points, improve safety factor.
* Laminated board <br>Equipped with anti-corrosion high-strength laminate, it is resistant to acid and alkali, and the load-bearing capacity of the laminate is up to 50KG.
* Liquid container <br>The bottom of the cabinet is equipped with anti-corrosion large-capacity liquid tank and liquid absorbent cotton, and the volume is up to 15L.
* Strong acid box <br>High-strength PP anti-calculation box can effectively suppress the emission of strong volatile organic acids and has strong corrosion resistance.

Technical parameters of the net gas storage cabinet

Probe + operation panel <br>The new design can detect the saturation of the filter and the pollution status of the laboratory online. The large LCD screen is displayed in PPM unit. It is corrected by American RAE company PID, with high accuracy, fast response and strong stability. .
Alarm point setting
Users can set appropriate alarm points to improve the safety level of the laboratory.

Huafeng Clean Air Type Pipeless Storage Cabinet:

** Online monitoring system can visually see the pollution of chemical gases in the experiment, and can know the use of the filter in time.

** No external piping is required, reducing the reliance on laboratory ventilation systems and the environment, saving time in retrofitting projects. Purification purposes are achieved in the short term. A storage cabinet consumes a small amount of electricity, consumes no air conditioning, and is quite energy efficient. It can be moved and added at any position and can be reused. Huafeng Jingqi type storage cabinet solves the environmental pollution caused by traditional ventilation methods and responds to the national low-carbon environmental protection policy concept.
