The dual bag filter is an efficient filtration device composed of two bag filter units connected in parallel. The main body is made of stainless steel 304/316 or carbon steel (surface anti-corrosion treatment) material. When the equipment is running, the two filtering units can work alternately. When one of the filter bags intercepts impurities and saturates and needs to be replaced, it can quickly switch to the other unit to ensure uninterrupted fluid filtration. It achieves impurity interception through high-precision filter bags, with a filtration accuracy of up to 1-200 microns, suitable for various fluids such as water, oil, coatings, etc. It is widely used in industries such as chemical, food, and environmental protection, effectively improving production continuity and filtration efficiency.
