Q: What are the materials of this automatic self-cleaning scraper filter?
A: The main body is made of corrosion-resistant stainless steel, such as 304 or 316L. The filter elements and scrapers will be made of wear-resistant polymer materials or special alloys according to different application scenarios to ensure durability and filtering effect.
Q: What is the filtering accuracy range of the equipment?
A: We provide a variety of specifications, with filtering accuracy ranging from 1 micron to 500 microns. According to your actual needs, including the type of filtered fluid, the size of impurities, etc., we can accurately match the appropriate accuracy for you, and also support customization.
Q: How long is the service life of the scraper?
A: The scraper material we choose is highly wear-resistant, and under normal working conditions, the service life can reach 3-5 years. Of course, the specific service life will also be affected by factors such as fluid properties and impurity content. We also provide scraper replacement services to ensure long-term and stable operation of the equipment.
Q: How does the equipment perform in the filtration of fluids with high impurity content?
A: Even in the face of fluids with high impurity content, the equipment can effectively cope with it. The automatic cleaning function can remove a large amount of impurities in time, keep the filter element transparent, and continue to filter stably. However, for situations with particularly high impurity content, we can also provide pre-treatment solutions and equipment selection suggestions to achieve better filtering effects.
