Henan Shuangxin Fire Environmental Protection Equipment Manufacturing Co., Ltd is one of the top ten manufacturers and supplier of HVAC air filter in China. We have specializing in HVAC air filter line for many years. And we have exported to more than 15 countries in recent years. with strong technical support, good quality and excellent services.
HVAC air filter is a device that captures dust from a gas-solid two-phase flow through the action of a porous filter material and purifies the gas. It purifies the air with low dust content and sends it into the room to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room.  
The HVAC air filter contains 3 type like below:
(1) Primary filter. The filter material of the coarse filter is generally non-woven fabric, metal wire mesh, glass wire, nylon mesh, etc.
(2) Medium efficiency filter. Commonly used medium-efficiency filters are: M-I, Ⅱ, Ⅳ foam plastic filters, YB glass fiber filters, etc. The filter materials of the medium-efficiency filter are mainly glass fiber, medium-pore polyethylene foam and synthetic fiber felt made of polyester, polypropylene, acrylic, etc.
(3) High efficiency filter. Commonly used high efficiency filters are GB type and GWB type. The filter material is ultra-fine glass fiber filter paper with very small pores. The use of a very low filtration rate enhances the screening and diffusion of small dust particles, so it has a high filtration efficiency.
Reasonably select the appropriate air filter according to the specific situation. The selection principles are as follows: 1. According to the indoor cleanliness and purification standards, determine the efficiency of the last stage of the air filter, and reasonably select the combination stage and each air filter. level of efficiency. 2. Correctly measure the dust content and particle characteristics of the outdoor air. 3. Correctly determine the filter characteristics. 4. Analyze the properties of dusty gas. Choosing Henan Shuangxin will be the smart choice.
