Primary filter cotton can be seen everywhere in our lives, with a wide range of applications and is safe and environmentally friendly. So, what is the scope and how to use primary filter cotton?

What is the scope and how to use primary filter cotton?

Primary filter cotton can be used in various industrial applications, such as spraying industry, electroplating industry, surface treatment, exhaust gas treatment, building ventilation, pollution prevention and control, public buildings, air conditioning industry, home appliance industry, automotive industry, motorcycle manufacturing, electronics industry, watch industry, pharmaceutical factory, food industry, packaging materials, furniture industry, decoration engineering and other ventilation and air conditioning system air purification fields.

How to use:

Primary filter cotton is actually a type of non-woven fabric made of 100% polyester fibers. After being heated at a certain temperature, it combines with the fibers to form irregular cross shapes, resulting in high dust capture efficiency, strong adhesion, and no breakage. This primary filter cotton is very economical, practical, safe, environmentally friendly, and easy to use. Used as a pre filter for purification systems, it can intercept particles and impurities larger than 5 millimeters in the air. It is widely used in the field of air purification and is also a very common filtering material.

The use of primary filter cotton is carried out in sequence. Firstly, cut the filter cotton according to the size of the air supply outlet, and install the cut filter cotton on the air supply outlet. It can be made into a panel or foldable design, and the outer frame can be a paper frame, aluminum frame, or galvanized frame. If washable filter materials are used, they can be cleaned and reused after a period of use, thereby reducing operating costs. Primary filter cotton can also be installed on automatic rolling screen filters, with the same filtering function. Nowadays, many manufacturers' equipment comes in different sizes, most of which are frame type and easy to install.

What is the difference between primary filter cotton and air filter?

1. Frame difference

The difference between primary filter cotton and air filter is that the air filter has an outer frame, which can be made of paper frame, aluminum alloy frame, galvanized frame, stainless steel frame, etc. The sturdy structure of the filter cotton combined with the outer frame can withstand greater air volume, and some special structures can also increase the filtering area and prolong the service life.

2. Material differences

The difference between air filter cotton and air filter lies in the filtering material, with air filter cotton being made of a larger material. Use polyester synthetic fiber or glass fiber, use ester synthetic fiber as air filtration material, glass fiber or ultrafine glass fiber filter paper, etc.

3. Filter level

The grades of primary filter cotton are divided into primary efficiency and medium efficiency, and the grades of air filters are divided into primary efficiency, medium efficiency, and high efficiency.

What is the service life of primary filter cotton?

If the service life of the primary filter cotton is used normally for 1 to 2 months under a certain rated air volume, the filter cotton needs to be replaced, or when the resistance of the filter cotton reaches 200 Pa or more, the filter cotton needs to be replaced; If the filter cotton can be washed with water, the replaced filter material can be washed with clean water or a solution containing neutral detergent, dried with compressed air or air dried before replacement; Allow cleaning twice.
