The primary filter in air filter products is also called rough filter. The primary filter is used as the front end filter in air filtration, which effectively protects the filter efficiency and service life of the lower filter. The primary filter is common sense and thick. What are the main contents of the instructions for use of the effective filter? The following high-efficiency air filters give you an explanation.

Introduction to Common Sense of Primer Filters

The use of metal materials such as aluminum, galvanized sheets, or cardboard as a framework for primary air filters feels somewhat Chinese and Chinese-made. The selection of air filter media is basically the same as that of a disposable paper frame primary filter. The main reason for the filter product to be made of a metal frame is strong and durable, saving maintenance and replacement costs of air filter production. Thanks to the use of a metal frame, it is only necessary to replace the filter element of the primary filter when it reaches the filter life, thus saving costs.

Due to the limitations of the initial effect filter and the use of the coarse filter, the use of non-woven fabric as the filter material is generally used for the metal frame rough air filter. However, it should be noted that some users always require filter manufacturers to use washable filter materials. In principle, as long as any filter material is rinsed with water (including rinsing), the filtration performance of its products will be greatly reduced, all parameters will be deteriorated, and severely, it will directly lead to filter scrap. Even if some air filter media can be used for flushing, it is at the cost of severely reducing filtration efficiency. Therefore, it is not recommended to sacrifice the filter performance in exchange for the longevity of this method of killing chickens and eggs. The correct method of use is to replace the filter element and replace the primary effect filter.

Rough filter instructions

The main raw material of rough air filter is non-woven fabric, glass fiber, etc. as filter material, wedge-shaped folding shape to increase the filter area, metal mesh clamp or built-in metal dragon skeleton support, together with metal frame, made of Plate structure. With a small resistance, long life, flushable, economical and durable.

Rough filter application

Rough air filters are generally used for pre-filtering of central air conditioning and centralized ventilation systems, and pre-filtering of gas turbines and air compressors.

Rough filter structure

The coarse filter structure is generally divided into a dragon skeleton and a frame skeleton. The dragon skeleton is characterized by strong and evenly distributed filter media, but it takes time and labor to produce. The frame skeleton is characterized by the convenience of changing the filter material, making the production time-saving, and the strength is slightly worse than the dragon skeleton.

Rough filter media

Rough air filter can be washed non-woven, activated carbon, synthetic fiber, chemical fiber (import), glass fiber (import), Jin convex mesh (nylon mesh). The most commonly used are non-woven fabrics and glass fibers. The efficiency can reach rough or medium efficiency.
