Free manual wash filter

The internal structure of SYL, STL and SZL is basically the same as ZZL (single cylinder) filter, but it is manually operated to clean the filter that is running, and it is very convenient to clean, without removing any part of the Y or T filter, as long as the drain valve is opened, and the handle on the filter is rotated 3-4 turns at the same time. After cleaning, immediately close the blowdown valve, then you can observe the difference in pressure of the two pressure gauges on the filter body before and after cleaning.
Only need
Filtration takes only a few minutes
Hold
Keep working continuously
The amount of water consumed
Only 1-2% of the average flow of the main pipeline
It can be seen that the filter can be manually cleaned and filtered in just a few minutes, and can maintain continuous work without stopping. The amount of water consumed by SYL and STL cleaning at one time only accounts for 1-2% of the average flow of the main pipe.
