Anping County Boli Hardware Wiremesh Products Factory, established in 1998 with an annual export value of US$5–10 million, introduces our Automatic Self-Cleaning Filter for Air, Steam, and Nitrogen – a robust solution for continuous filtration in demanding industrial processes. Engineered with 316L stainless steel and a 220V/50Hz electrical system, this filter eliminates the need for manual cleaning, reducing downtime and maintenance costs. Experience reliable, efficient filtration that adapts to your gas or steam applications, backed by over two decades of manufacturing expertise.
Our automatic self-cleaning filter operates on a differential pressure control principle. When the filter element accumulates debris, the pressure drop triggers an automatic backwash cycle. The cleaning process uses a small portion of the filtered fluid or an external source to flush contaminants out through a drain valve, all while the main flow continues uninterrupted. This design ensures continuous operation, consistent filtration quality, and minimal pressure loss across the system.

Frequently Asked Questions
1. How often does the filter need to clean itself?
The cleaning cycle is triggered automatically by the differential pressure across the filter element. Typically, when the pressure drop reaches a preset value (e.g., 0.5 bar), the backwash starts. The frequency depends on the contaminant load – in clean gas systems, it may be once every few hours; in heavy dust conditions, it could be more frequent. The cycle duration is adjustable via the controller.
2. Can this filter be used for high-temperature steam?
Yes, the 316L stainless steel construction and high-temperature seals allow operation up to 250°C. For steam above 200°C, we recommend confirming the specific gasket material (e.g., graphite) to ensure long-term reliability. Our standard configuration is suitable for saturated steam up to 180°C; higher temperature options are available upon request.
3. What is the pressure drop during normal operation?
The initial pressure drop across a clean element is typically 0.1–0.3 bar, depending on the flow rate and filtration precision. The filter is designed to operate with a maximum allowable pressure drop of 0.5 bar before cleaning. After backwash, the pressure drop returns to near the initial value.
4. What media can be filtered besides air, steam, and nitrogen?
This filter is suitable for non-aggressive gases and vapors. For corrosive or toxic media, we recommend discussing material compatibility. It can also be used for light liquid filtration (e.g., water, oils) with adaptation, but the primary design is for gas/steam applications.
5. How is the backwash performed – does it interrupt the main flow?
No, the backwash process is conducted while the filter remains online. A small portion of the filtered fluid is used to reverse flow through the element, flushing debris out through the drain. The main flow is only minimally affected during the brief cleaning cycle (typically 10–30 seconds).
6. What is the lifespan of the filter element?
The 316L stainless steel woven wire mesh element is durable and can last for years under normal operating conditions. The self-cleaning mechanism prevents clogging and extends element life. Periodic inspection (e.g., every 6–12 months) is recommended; replacement is only needed if the element is damaged mechanically or chemically.
7. Can the filter be customized for different connection sizes or pressure ratings?
Yes, we offer customization options including flanged connections from DN50 to DN300, higher pressure ratings (e.g., 2.5 MPa), and alternative materials (e.g., 304L, duplex). Please provide your specific requirements, and our engineering team will design accordingly.
8. What is the power consumption during backwash?
The power consumption is low: the 220V/50Hz controller and electric drain valve draw only about 50–100W during operation. The backwash itself uses a small amount of fluid (typically 1–3% of the main flow) for flushing, depending on the filter size.
