How do we choose the right Air-Conditioning Filter Element?

With the fall of autumn and winter temperatures, haze weather has begun to appear in various places, and air pollution has brought great hidden dangers to people's health. Therefore, effective protective measures are quite necessary. For cars, air conditioning filters are like masks, blocking pollutants in the air from entering the car from the source. So how do you choose an air conditioning filter? Let's take a look at the High Flow Rate Filter Factory.

1. Ordinary filter paper type: ordinary filter paper type air-conditioning the filter element is made by folding the white filament nonwoven fabric to form a certain thickness of folds, so as to realize air filtration. Because its filter layer is mainly made of ordinary filter paper or non-woven fabric, it can only perform simple filtering on air, and it has a poor filtering effect on formaldehyde or PM2.5 particles. Most of the models are equipped with original air-conditioning filters when they leave the factory.

2. Activated carbon filter element: The activated carbon filter element is based on the fiber filter layer, and the activated carbon layer is added to upgrade the single-effect filter to double-effect filter. Youxin used car tips because activated carbon has the characteristics of adsorption, in addition to adsorbing harmful gases such as formaldehyde, it also has the effect of removing odors. Youxin used car tips, an activated carbon filter is better than the ordinary filter paper type.

HEPA Filter with Partition

3. HEPA Filter with Partition: The standard of HEPA is that the filtration efficiency for particles with a diameter of 0.3 microns (PM0.3) is 99.97%. Youxin used car tips: HEPA's filtering ability is very strong, and it is the best of all filter materials in filtering PM2.5. HEPA filters are also often used in air purifiers. A single HEPA filter can only play a single-effect filtering role, the filter effect on harmful gases such as formaldehyde is poor.

4. HEPA filter paper + activated carbon layer filter element: This is a composite air conditioning filter element, which uses two types of filter layers, HEPA filter paper and activated carbon, to play a dual-effect filtering role. Youxin used car tips: air enters HEPA filter paper to filter particulate matter, remove PM2.5, and then adsorb harmful gases through the adsorption of the activated carbon layer, and finally send clean air into the air conditioning system.

The filter cartridge is a cylindrical element used for filtering and is generally divided into a gas medium and a liquid medium. The filter cartridge is a surface filter element. It uses tiny breathable tissue formed on the surface of the filter material to block out particulate matter in the gas.

The filter materials of common filter cartridges are wood pulp fiber filter paper and spunbonded polyester fiber non-woven fabric, of which polyester non-woven fabric can be coated, oil-proof, water-proof, and anti-static treatment.

The installation method of the filter cartridge is divided into vertical hoisting, oblique mounting according to a specific angle, and flange mounting.

The commonly used automatic cleaning methods for filter cartridges are high-pressure gas pulse backflush and mechanical vibration. Pulse backflushing uses a preset parameter of the controller to give a signal to the solenoid valve, instantly opens and closes the solenoid valve diaphragm, so that the high-pressure gas enters the blowing pipe, and uses the rapid expansion of the gas to shake off the dust on the surface of the filter cylinder. We set it to about 6 kg. Mechanical vibration dust cleaning is commonly used in Dust Removal Filter Cartridge. It uses the vibration force generated by the eccentric device on the dust collector plate to remove dust. This action needs to be operated after stopping.
