Answers to common questions about air filters
Answers to common questions about air filtersI. What is the difference between a high-efficiency filter with and without a partition?A: The difference between high-efficiency air filters with and without spacers lies in the fact that the nominal dimensions include the outer frame and the filter media, while the actual dimensions will remove the outer frame and only calculate the width, height, and depth of the filter media as well as the area of the filter media. II. Is there any similarity between HEPA filters with and without partitions? A: Partitioned high-efficiency filters are made of ultra-fine glass fiber as filter media, with glue board paper and aluminum platinum as dividers, and then combined with wooden or aluminum alloy frames, which are characterized by high filtration efficiency, low resistance, and high air volume, and are used in various local purification equipment and clean plants. Compared with the partitioned high-efficiency filter, it is smaller in size, lighter in weight, and more compact in the structure under the same air volume. III. What is the standard number of folds, the height of folds, and the formula for conversion of filter media with and without partitions? A: The folding height of filter paper with a partition is usually shorter than the nominal height of about 30mm - 34mm, and the folding number is mainly determined by the partition paper and the tightness of the assembly of filter paper and partition paper. The relative number of filter paper folding without a partition is mainly determined by the filter paper folding height and the tightness of the filter paper. IV. What is the similarity between "PP HEPA" and glass fiber "HEPA" in junior high-efficiency air filters? A: 1. PP HEPA is not irritating to human skin, while HEPA is irritating to some extent. 2. PP HEPA does not shed fibers, while HEPA does. |
