What is the difference between the plate type and the bag type in the primary efficiency filter?

The primary efficiency air filter is suitable for primary filtration of air conditioning systems, mainly used for filtration 5 μ Dust particles above m. There are four types of primary efficiency filters: plate type, folding type, bag type, and box type. The outer frame materials include paper frame, aluminum profile frame, and galvanized plate frame. The filter materials include non-woven fabric, nylon mesh, activated carbon filter material, metal mesh, and aluminum rolled mesh.

The advantages of initial efficiency filters are low cost, light weight, good versatility, and compact structure.

Primary efficiency plate filter:

It is a special filter equipment made of non-woven fabrics, glass fibers, etc. as filter materials, wedge-shaped folding molding to increase the filtering area, metal mesh clamping or built-in metal dragon skeleton support, coupled with a metal outer frame, and made into a plate structure. It is characterized by low resistance, long service life, washability, economy, and durability.

The primary filter structure is generally divided into a dragon skeleton and a frame skeleton. The keel frame is characterized by its strong structure and uniform distribution of filter materials, but its production takes time and labor. The frame skeleton is characterized by convenient replacement of filter materials, time-saving production, and slightly lower strength than the dragon skeleton.

Plate type primary efficiency filters are generally used for prefiltration in central air conditioning and centralized ventilation systems, large-scale air compressor prefiltration, clean return air systems, and local high-efficiency filtration devices.

Primary efficiency bag filter:

It is a multi-purpose filtering device with novel structure, small size, simple and flexible operation, energy saving, high efficiency, airtight operation, and strong applicability. Bag filter is a new type of filtration system. The inside of the bag filter is supported by a metal mesh basket. The liquid flows in from the inlet and flows out from the outlet after being filtered by the filter bag. Impurities are trapped in the filter bag, which can be reused after replacement.

The primary effect bag filter uses synthetic fibers with gradually increasing density and strong toughness, and adopts seamless fusion bonding technology, which has good air tightness and bonding strength, preventing air leakage or cracking when the wind pressure is high. The unique support design inside the bag ensures its stable and optimal filtering effect; The filter material itself does not contain organic silicon, which is particularly suitable for use in paint shops.

The bag type primary efficiency filter is applicable to the front filtration of automotive paint shops in the coating industry and air conditioning applications, such as air conditioning systems in commercial buildings, warehouses, schools, laboratories, and other places.

The primary filter should select products with a large effective filtration area, while also taking into account the structure of the filter screen and on-site usage conditions. For example, a bag filter can increase the filtering area by increasing the number of filter bags and the length of filter bags; For plate filter screens, the filtering area can be increased by increasing the thickness of the plate filter screen or the discounted number of filter elements. Of course, it is also necessary to consider whether on-site conditions allow, for example, whether the original length of the filter section of the air conditioning unit allows for an increase in the length of the bag, and whether the installation frame of the plate filter allows for an increase in the thickness of the plate filter! Of course, for users, it is still necessary to find more professional people to customize the design.
