The primary filter structure of the paper frame adopts disposable cardboard frame filter. The outer frame is generally divided into ordinary cardboard frame and high-strength touch-cut cardboard. The filter element is a pleated fiber filter material lined with single-sided metal wire mesh. Beautiful appearance. The structure is strong and durable.
Generally, cardboard frames are used to make non-standard filters, which can be used for the production of filters of any specification. They are high-strength and should not be deformed. High-strength touching and cardboard are used to manufacture filters of standard specifications, which are characterized by high specification accuracy, beauty and low cost. If imported surface fibers or synthetic fibers are used to filter materials, their performance indicators can reach or exceed similar products of imported filters.
Primary filter material of paper frame: It is folded into high-strength touch and cardboard in the form of folding, increasing the windward area. Dust particles in the air flowing are effectively blocked between the folds and the folds by the filter material. Clean air flows evenly from the other side, so the air circulation filter is gentle and uniform. Depending on the filtration material, the particle size it blocks varies from 0.5μm to 5μm, and the filtration efficiency is also different.
The frame of the primary filter is generally made of four materials: paper frame, aluminum alloy frame, galvanized frame and stainless steel frame. The cost and cost of the paper frame are relatively cheap and widely used. It is mainly used in purifying air conditioning units, central air conditioning units, fresh air inlets, dust-free room dust removal equipment entrances, etc.
Initial filter efficiency of paper frame:
It is mainly divided into four types of efficiency: G1, G2, G3 and G4.
G1 filter efficiency of 40% for 5um (micron)
G2 level is 65% efficient for 5um (micron) filters
G3 filter efficiency 85% for 5um (micron) filter
G4 level 90% efficiency for 5um (micron) filter
The paper frame primary filter is combined with the high-efficiency filter to prevent the high-efficiency filter from being replaced prematurely due to dust accumulation, thus prolonging the service life of the high-efficiency filter.
Excellent performance and strong structure
High-quality fluffy filter paper increases the dust capacity.
Iso-height pleat design
Filter paper containing antibacterial agents can be provided.
Primary filter structure of paper frame:
1. Large ventilation, low resistance and low operating energy consumption.
2. The dense non-woven filter cotton filter material effectively removes atmospheric dust particles, and the filtration efficiency of 5μm dust particles is more than 90%.
3. Frame: paper frame (if the quantity is small, it is generally handmade and mold stamped in large quantities). In addition, you can choose galvanized frames, aluminum alloy and stainless steel.
4. Large dust capacity and long service life.
The structure has been greatly changed. The original iron skeleton support is removed from the primary filter of the paper frame and the filter with supporting iron mesh is used for weighting. This design not only simplifies the manufacturing process of the primary filter, but also reduces the cost to a certain extent, and ensures the same performance advantage.
Note: The size of the primary filter of the paper frame can be selected for regular thickness: 15mm, 21mm, 25mm, 46mm, 50mm, 80mm, 96mm, etc.
