Our bag filter is a high-performance pressure filtration equipment designed for solid-liquid separation and fluid purification in various industrial fields. It is composed of a filter cylinder, filter bag, reinforced metal mesh basket, and quick-opening sealing mechanism, adopting a scientific structural design to ensure airtight operation and strong applicability. The working principle is simple and efficient: the fluid enters from the inlet, passes through the filter bag for precise filtration, impurities are intercepted in the filter bag, and the qualified filtrate flows out from the outlet. It can be used continuously by replacing or cleaning the filter bag, which is easy to operate and low in maintenance cost. Our bag filters are manufactured in strict accordance with international standards, with a filtration precision range of 0.5-100μm, which can meet the diverse filtration needs of different industries and comply with the stringent emission norms implemented in more than 30 countries worldwide.

FAQ (Frequently Asked Questions)
Q1: What is the filtration accuracy range of your bag filters, and can it be customized?A1: The standard filtration accuracy ranges from 0.5μm to 100μm, which can meet the needs of most industrial filtration scenarios. We also provide customized services according to your specific filtration requirements, such as ultra-high precision filtration (below 0.5μm) for electronic semiconductor and other fields.
Q2: How often should the filter bag be replaced, and is it easy to operate?A2: The replacement cycle depends on the impurity content of the filtered fluid and the filtration precision, usually 1-4 weeks. Our bag filters adopt a quick-opening or rocker arm design, which allows a single person to complete the bag replacement without tools, and the whole process only takes 3-5 minutes, greatly reducing downtime.
Q3: What materials are your bag filters made of, and are they suitable for corrosive fluids?A3: The filter body is available in 304 stainless steel, 316L stainless steel, carbon steel and PP plastic. Among them, 316L stainless steel has extremely strong corrosion resistance, which can be used to handle high-corrosion fluids such as acids and alkalis, and there is no risk of material dissolution, which is suitable for harsh working conditions in chemical and electroplating industries.
Q4: Do your bag filters comply with international industry standards, and can they pass relevant certifications?A4: Yes, our bag filters are designed and manufactured in strict accordance with GMP, HACCP, FDA and ASME standards, and can pass relevant certification tests. They are widely used in food, beverage, pharmaceutical and other industries that have high requirements for hygiene and compliance.
