The Amiad SIGMA is the first real innovation in Automatic Hydraulic Filter design in 25 years and showing performance well above existing filters for the irrigation market
Sigma includes five screens to create a large 6000 cm2 filtration area relative to its compact size. This enables the state-of-the-art filter to handle high flow rates while maintaining a small footprint and reducing startup costs
Unique mechanical components
Run by an advanced single hydraulic turbine and a smart gear, Sigma significantly reduces running costs. Requiring no power source and operating at a minimum pressure of 1.5 bar/22 psi during the flush cycle, the solution lowers energy consumption Based on Amiad’s suction-scanning screen technology, Sigma carries out automated focused flushing to reduce self-cleaning frequency. And by utilizing less flushing water while continuously filtering, Sigma further lowers overall water consumption.
