High efficiency, low resistance and large dust holding capacity: the knife frame high efficiency filter without partition can effectively filter particles above 0.3μm, with a high filtration efficiency of more than 99.99%, and at the same time, it has low resistance, which ensures good ventilation performance. In addition, it has a large dust capacity and can maintain a stable filtration effect for a long time.

Convenient installation and good sealing performance: the filter has a simple design, easy and quick installation, and the surrounding area is sealed with a special hermetic sealing agent, which ensures the sealing of the whole filter and avoids leakage problems.

Installation and Maintenance

When installing the knife frame type high efficiency filter without partition, first of all, you need to make sure that the direction of airflow is the same as the direction of the arrow mark on the outer frame. Before installation, the equipment should be inspected to confirm that there is no damage or leakage, and to ensure that the filter media, sealant and frame are intact. In addition, it is also necessary to ensure the cleanliness of the installation environment to avoid the introduction of pollutants during installation.

Precautions for use

In the process of use, the air inlet surface of the filter should be checked regularly to see if there is any clogging of debris and whether the surface of the filter media is damaged. Once it is found that the surface of the filter media is seriously damaged, the filter must be plugged or replaced with a new one. At the same time, make sure that the sealing at the pressure edge with the frame is good to prevent air leakage.

Replacement cycle

The replacement cycle of the high-efficiency filter is related to its operating environment and use conditions. In general, when the resistance of the equipment reaches 600Pa or more, or after one year to one and a half years of use, it is necessary to replace the filter with a new one. In addition, if a less efficient filter is used as a pre-filter, its service life cycle will be shortened.

Warranty and Maintenance

In order to ensure the long-term stable operation of high-efficiency filters, regular maintenance work is required in addition to regular replacement. This includes cleaning the filter media, checking the tightness of the frame and checking the integrity of the sealant. Especially when used in harsh environments, more attention should be paid to strengthening the frequency and methods of filter maintenance.

Design Characteristics

Knife frame high efficiency filter without separator is a kind of filtration device designed for filtering air suspended particles above 0.3μm, which is widely used in the end filtration link of various filtration systems. Its core lies in the use of ultra-fine glass fiber filter paper as the filter media and hot melt adhesive as the separator. This design not only reduces the running cost, but also ensures the consistent spacing of pleat layers inside the filter, optimizes the airflow path, and achieves a high dust holding capacity and high efficiency filtration performance. In addition, the filter is sealed around the perimeter with a special sealant to ensure overall tightness and prevent air leakage. Plastic spraying mesh is installed on the inlet and outlet surfaces to protect the filter paper from damage. Each filter has undergone rigorous testing and has a filtration efficiency of H13 and H14 levels, in accordance with the EN1822 standard.

Product Size and Specific Parameters

The knife frame high efficiency filter without partition has various sizes, including but not limited to 320320110mm, 484484110mm, 610610110mm and other different sizes, corresponding to the rated air volume of 400, 900, 1450 m³/h, etc., with a dust holding capacity of about 250g, and the initial and final resistances between 400-600 Pa. The specific values of these parameters may vary depending on the product specifications.
