In the process of filter replacement and purchase, many customers obtain the size information from the label on the filter itself, but different companies may represent different ways, resulting in the final written data and actual data products. A certain degree of difference! Below, we will give a brief introduction to the labeling method of the filter size, so that the buyer can more clearly express the product parameters that he wants to send:

Filter specification dimensioning method:

Labeling of seesaw filters and high efficiency filters

Width × height × thickness / efficiency

For example: 595 × 290 × 46 / G4

Width: the horizontal dimension mm when the filter is installed;

Height: the vertical dimension mm when the filter is installed;

Thickness: the dimension mm in the direction of the wind when the filter is installed;

Labeling of the bag filter

Width × height × bag length / bag number / efficiency / filter frame thickness

For example: 595 × 595 × 500 / 6 / F5 / 25 290 × 595 × 500 / 3 / F5 / 20

Width: the horizontal dimension mm when the filter is installed;

Height: the vertical dimension mm when the filter is installed;

Bag length: the dimension mm in the direction of the wind when the filter is installed;

Number of bags: the number of bags in the filter;

Frame thickness: the thickness dimension of the frame along the wind direction when the filter is installed;

For general ventilation filters, the nominal size 24" (610mm) has become the mainstream of domestic filtration products.

Inch, although there is no standard in the country to specify this size, Table 2 is the size of the bag filter.
