Ultra-fine glass fiber sub-high efficiency filter

Ultra-fine glass fiber sub-high efficiency filter It uses ultra-fine glass fiber filter paper or polypropylene filter paper as the filter material and is densely folded.
The densely folded filter paper of the sub-high-efficiency filter is separated by small inserts made of paper partitions or aluminum foil partitions to maintain a smooth channel. The outer frame is made of galvanized plate, stainless steel plate or aluminum alloy profile, and is sealed with a new type of polyurethane sealant.

Sub-high-efficiency filters can be widely used for general filtration in electronics, pharmaceuticals, hospitals, food and other industries, and can also be used in high-temperature resistant places.
The partition-less sub-high-efficiency filter uses ultra-fine glass fiber filter paper or polypropylene filter paper as the filter material, separated by hot melt glue. The outer frame is made of cardboard, aluminum alloy profiles or galvanized sheets, and is sealed with environmentally friendly polyurethane sealant.

Sub-high-efficiency filters are generally used in semiconductor manufacturing plants, atomic force research centers, clean rooms, laminar flow equipment, workbenches and other places that require ultra-high cleanliness.

1. The sub-high-efficiency filter has unique seamless sealing technology, which has better sealing effect, is more durable, and is less likely to leak;

2. The filter material of the sub-high-efficiency filter has a metal guard net on both sides;

3. Sub-high efficiency filters are available in 50mm, 69mm, 90mm and other thicknesses;

4. Laser scanning and counting MPPS efficiency one by one: 95%-99.95% (EN1882);

5. Filtration level: H10-H12 (EN1882).

Sub-high efficiency filter classification:
Sub-high-efficiency filters with partitions include GK (sub-high-efficiency filters with partitions), GKW (sub-high-efficiency filters with high temperature resistance), GKA (sub-high-efficiency filters with high humidity resistance); sub-high-efficiency filters without partitions include GKYW ( Combined combined sub-high efficiency filter), GKYS (sub-high efficiency filter without partitions), GKYC (liquid tank type sub-high efficiency filter), GKYL (ultra-low resistance sub-high efficiency filter without partitions), GKYD (knife holder Type no partition sub-high efficiency filter).

The appearance of sub-high-efficiency filters is the same as that of ordinary HEPA high-efficiency filters. According to their structures, they are divided into partitioned, non-partitioned, and combined sub-high-efficiency filters: 1) Traditional high-efficiency filters with partitions have been used for half a century. Filter products commonly used in clean engineering. Due to many advantages such as simple manufacturing, low price, temperature resistance, and impact resistance, partitioned filters still occupy an irreplaceable position in many occasions as filter types are constantly updated.

Sub-high efficiency filter with partition
1. The basic size is 610mm (24''), an international standard;
2. Classic specification with basic size of 484mm;
3. The basic size is 630mm.

Main performance of sub-high-efficiency filter with partition Filtration efficiency (sodium flame method): 90%-99.9% Filter material: fiberglass filter paper Frame: galvanized steel plate, multi-layer plywood Partition: aluminum foil, cardboard Sealant: polyurethane work Temperature: -20~90 degrees Celsius Humidity: aluminum partition, <=99% paper partition, <=85%

2) The partition-less design of the Ultra-fine glass fiber sub-high efficiency filter can achieve maximum efficiency with minimum resistance, thereby reducing operating costs. The specially designed hot-melt insulation glue can ensure the same pleat spacing to ensure optimal airflow while achieving High dust holding capacity, making full use of the filter media throughout the depth of the filter. The partition-less sub-high-efficiency filter is composed of waterproof and flame-retardant glass fiber filter paper or PP high-efficiency filter material. An aminoacetic glue is used to fix the filter material on a lightweight acid sand aluminum extruded profile frame. The surface can be equipped with a spray-coated protective net to protect the filter paper from damage. The light weight, small and compact design makes it easy to install in open cabinets, fan distributor units and clean benches. The combined sub-high-efficiency filter is also a type of sub-high-efficiency filter without partitions. All HEPA high-efficiency filters and sub-high-efficiency filters produced by our company have been tested for performance one by one before leaving the factory.
