Cooling Tower Automatic Backflush Shallow Sand Filter (YL-SF-2200)
Cooling Tower Automatic Backflush Shallow Sand Filter (YL-SF-2200)
Product Overview
The YL-SF-2200 is a bypass filter designed for chilled water systems in closed industrial circulation setups. It efficiently filters circulating chilled water and supports both manual and automatic backwashing. Typically, the system undergoes backwashing every 3 to 7 days, ensuring consistent and high-quality water after long-term operation. This filter helps maintain stable performance and reduces maintenance efforts. Its low water consumption makes it ideal for use in industrial and commercial chilled water systems, as well as in central air conditioning units. Users can connect multiple bypass filters in parallel based on the system’s flow requirements and pipe size, with wastewater discharged into the sewerage network.
Key Features
1. Flexible control options: Manual or automatic backwash.
2. Simple and reliable water distributor.
3. Durable finished water collector with a long service life.
4. Easy installation—just connect the inlet and outlet to the waste pipe.
5. Low backwash water usage due to a uniform filter design, extending the backwash cycle.
6. High-efficiency backwash with an advanced water collector for optimal cleaning.
