Sand gravel filter with automatic washing FGA-80
The gravel horizontal filter is meant exclusively to pre-filtrate drip irrigation water of mechanical impurities and microweeds while withdrawing water from surface sources.
Since filter washing will be made automatically (unmanned) and with no dwell of irrigating. Using automatic machinery in the gravel filter allows avoiding operator errors fraught with blocking the filter and dwell of irrigating, and also reduces the common time of washing and filter service.
Advantages

1. Continuous irrigation without expenditure of time for filter washing.
2. Saving time and water on filter washing.
3. Maintenance low cost.
