Cooling Tower Automatic Backflush Shallow Sand Filter (YL-SF-2200) Product Overview The YL-SF-2200 is a by-pass filter designed for chilled water systems in closed industrial circulation setups. It is used to clean circulating chilled water, and it offers both manual and automatic backwash options. Typically, the system is cleaned once every 3 to 7 days, ensuring improved water quality and long-term stable performance. This filter has low water consumption and is widely applied in industrial and commercial chilled water systems, as well as refrigerant and heat medium water systems in central air conditioning units. Users can install multiple by-pass filters in the main return pipes based on the system's flow rate and pipe size, allowing for efficient filtration and maintenance. The waste water from backwashing is then directed into the sewage network. Key Features of the Filtration System: 1. Available with both manual and automatic control options 2. Simple, uniform, and reliable water distributor 3. High-strength 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 consumption due to the use of a homogeneous filter media, which extends the backwash cycle 6. High backwash efficiency using an advanced water collector design FAQs: 01. What size of solid particles need to be removed? 02. How dirty is the water? 03. How will the filtered water be used? 04. What is the source of backwash water needed for cleaning? Specifications:
