Characteristics of commercial range hood products:

1. The oil fume removal efficiency is 98%, which meets the standard of high efficiency. The intelligent digital display screen reflects the real-time operation status of the equipment.

2. The all stainless steel electric field ensures that cleaning does not reduce the purification rate and has a long service life. The serrated design of 304 stainless steel provides strong ionization effect.

3. Full core manufacturing improves the stability, reliability, dust and water resistance of the electronic control system, and the adsorption capacity does not deteriorate.

4. The shell is made of 201 stainless steel, which has a long service life under harsh outdoor conditions.

5. Cost saving, versatile, easy to install for low altitude emissions, and space saving.

Product advantages:

1. Complete certificates; 2. Intelligent constant voltage power supply; 3. Stainless steel electric field; 4. High purification effect; 5. Full stainless steel shell; 6. Photocatalytic efficient deodorization;

Working Principle:

The working principle of commercial range hoods is generally that the gas containing oil fume particles passes through the internal electric field under the action of external electrostatic high voltage. Due to the discharge of the electric field, the oil fume particles are ionized. At this time, under the action of the cathode and anode plates of the electric field, negative ions and cations move and adsorb towards the plates respectively, thus achieving the separation and purification effect. It is not difficult to see that electric fields and power sources that can generate high voltage are very important for the purification effect of equipment, and can be said to directly affect the purification effect of equipment.

Materials for electric field and power supply:

Let's first take a look at the electric field. In the commercial range hood industry, three materials are often used in the production of electric fields: stainless steel, aluminum alloy, and galvanized sheet. From the perspective of purification effect, these three materials are stainless steel>aluminum alloy>galvanized sheet, and their costs are consistent with the above ranking. Although stainless steel has the best effect, aluminum alloy, which is not much different from it, is mostly used in the industry. After all, the price of a good smoke hood integrated machine should also be "good", while galvanized sheet, which has the worst effect, is not so "good".

The power supply plays a role like the "heart" in commercial range hoods. If the power supply loses its function, even if the electric field is made of excellent materials, it will lose its function. Commercial range hoods inevitably encounter various problems during use, but the most important thing is that high-quality power supplies will maintain constant voltage and current to ensure that the purification efficiency always meets the standard!

Purification standard:

The catering industry has a clear national standard for the purification of cooking fumes: the "Emission Standard for Cooking Fumes GB18483-2001". All sales of such products must obtain the National Environmental Product Certification (CCEP certification) to demonstrate compliance with the national standards before they can be sold.

In the "Emission Standards for Cooking Fumes in the Catering Industry" issued by China in 2001, the threshold for oil fume emissions was set at 2.0mg/m3. However, due to the booming development of the catering industry, the previous standards are not very applicable now. Therefore, starting this year, most regions have implemented a new and stricter oil fume emission threshold of 1.0mg/m3. When installing and using a hood integrated machine, the content of oil fume in the purified exhaust gas must be less than 1.0mg/m3 to meet the standard, which is considered a "good" commercial range hood. In addition, commercial range hoods must also comply with a series of other standards, such as "Technical Requirements and Testing Technical Specifications", "Air Pollutant Emission Standards", etc.
