High efficiency and low resistance

The liquid tank type high efficiency filter without partition adopts ultra-fine glass fiber filter media, which has extremely high filtration efficiency. At the same time, its design optimizes the airflow path, significantly reduces the operating resistance, and ensures efficient and smooth air circulation.

Light weight and easy installation

Due to the partitionless design, the weight of the liquid tank type HEPA filter is greatly reduced, and the installation process is simple and does not require complicated tools and long waiting time, which greatly improves the construction efficiency.

Low operating costs

The panelless design not only reduces weight, but also lowers operating costs. Because of the low resistance, the energy consumption of fans and other driving equipment is reduced accordingly, thus realizing energy saving and emission reduction with significant economic benefits.

Long service life

The outer frame of liquid tank type high efficiency filter without partition usually adopts corrosion-resistant and high-strength aluminum alloy profile, and the filter media is also made of durable and high-performance materials, so the overall structure is solid and ensures a long service life.

Good sealing performance

The sealing performance of the filter is crucial, and the liquid tank type high efficiency filter without partition adopts special liquid tank sealing technology to ensure efficient sealing between the filter and the frame, avoiding air leakage and ensuring the filtration effect.

Applications

Liquid tank type high efficiency filter without partition is suitable for terminal filtration of various clean plants with vertical air supply. It is widely used in pharmaceuticals, hospitals, food hygiene, microbiology and other high-grade sealed air purification terminal.

Technical specifications and performance test

The technical specifications of liquid tank type high efficiency filter without partition include filtration efficiency, filter material, filter paper spacing, partition design and other parameters. For example, the filtration efficiency is usually required to reach 0.3μm, 99.99%. Filter media usually use glass fiber, manufacturers to provide valid data or third-party test certificate. Filter paper spacing should be less than or equal to 3mm, and aluminum film is used as the separating material for the design of partition.

Installation and Maintenance

The installation of liquid tank type non-spacer HEPA filters usually requires professional personnel to ensure the sealing performance and filtration effect. During installation, attention should be paid to the quality of the sealant and the depth of the liquid tank to ensure good sealing around the filter. For maintenance, the integrity and cleanliness of the filter should be checked regularly, and it should be replaced or cleaned in time if it is damaged or contaminated.

Precautions

The quality of sealant and the depth of liquid groove should be ensured during installation to ensure good sealing around the filter.

Regular maintenance and repair should be carried out to ensure the long-term use effect and safety of the filter.

During use, the integrity and cleanliness of the filter should be checked regularly, and it should be replaced or cleaned in time if damaged or contaminated.

Design Features

The liquid tank type high efficiency filter without septum is a kind of end filter of the filtration system designed for filtering air suspended particles above 0.3μm. It adopts ultra-fine glass fiber filter paper as the filter media and is separated by hot melt adhesive. This design not only reduces the running cost, but also ensures that the pleats inside the filter are spaced consistently so that the airflow can pass through smoothly to achieve a high dust holding capacity, and makes full use of the overall depth of the filter to improve the efficiency of the filter media. In addition, the filter is sealed with a special sealant all around to ensure the sealing of the whole filter and avoid the leakage of pollutants. The inlet and outlet surfaces of the filter are fitted with plastic spraying protective mesh, which effectively protects the filter paper from being damaged. The air outlet side of the filter is equipped with a flange, and the inside of the flange is filled with liquid tank sealant to further enhance the sealing performance. The sealant in the tank is a non-Newtonian liquid, which has the advantages of non-volatile, non-oil creeping, acid and alkali resistance, non-toxic and odorless, and at the same time, it has good flame retardancy and stable electrical insulation properties. Since the air outlet side of the filter has a flange, the size of the air inlet side and the air outlet side may not be the same, so customers need to provide the specific size of the air inlet and outlet sides when ordering. Each filter will undergo rigorous testing to ensure that its performance is up to standard. The filtration efficiency class is divided into two grades, H13 and H14 (EN1822), which correspond to different filtration effects.

Materials and Operating Conditions

The main materials of the liquid tank type high efficiency filter without separator include ultrafine glass fiber filter paper, PU two-component polyurethane AB adhesive as sealant, aluminum profile as frame material, and sprayed diamond mesh as protection net. EVA hot melt adhesive is used for the separator, while EVA or neoprene is used for the sealant strip. Together, these materials form the core of the filter, providing high filtration efficiency and long service life. The filter is able to operate normally in temperatures up to 70°C and humidity up to 80%, ensuring stability and reliability in different environments.

Specification parameters

The specification parameters of the liquid tank-type non-spacer HEPA filters include a wide range of sizes and airflow configurations to meet the needs of different application scenarios. For example, some models have an external dimension of 320×320×69mm, a rated airflow of 250m³/h, resistance control within the range of ≤200Pa, and filtration efficiencies up to levels such as H13. There are also models such as 484 × 484 × 93mm, rated air volume of 1000m³/h, resistance between 400-600Pa, also in line with the H13 level of filtration efficiency. The specific values of these parameters may vary according to different product models and application requirements, but overall they all ensure high filtration efficiency and low operating resistance.
