Amiad Mini Sigma 80mm Fully Automatic Self-Cleaning Screen Filter with ADI-P Bluetooth DC Controller - 1600cm² (160-830LPM)
Amiad Mini Sigma 1600cm2 80mm (3") Automatic Filter C/W ADI-P Bluetooth DC Controller
The Amiad Mini Sigma 80mm Self-Cleaning Screen Filter is a compact and durable automatic filtration system designed for agricultural, landscape, and municipal irrigation. Built from reinforced polyamide for corrosion resistance, it provides long-term reliability in tough water conditions while remaining lightweight and easy to install.
Featuring Amiad’s suction-scanning cleaning technology, the Mini Sigma automatically cleans the entire screen area while using less than 1% of the process water — the lowest flush ratio in the industry. Cleaning is triggered by differential pressure, timer intervals, or manually via the controller or mobile app, ensuring uninterrupted filtration with minimal water and energy use.
This 80mm model is fitted with the ADI-P Bluetooth DC Controller, allowing remote monitoring and control via smartphone. The ADI-P app displays flush cycles, differential pressure, alerts, battery status, and performance history, making system management more efficient.

HOW IT WORKS
General
Amiad’s Mini Sigma filter is the newest addition to the Sigma family. It is a small and lightweight yet durable filter; quick and easy to install, simple to operate, and requires minimal maintenance. The Mini Sigma filter was developed to handle low pressure operation, with a capacity of up to 80 m3/h (352 gpm) and with filtration degrees from 80-500 micron. Inlet/outlet connections are available in 50 mm (2”), 80 mm (3”), and 100 mm (4”) diameter. Filters include a 40 mm (1.5”) flush valve.
Raw water enters through the filter inlet and passes through the screen. Clean water flows through the filter outlet. The gradual dirt buildup on the screen’s inner surface causes a filter cake to develop, creating an increase in the pressure differential across the filter system. A differential pressure (DP) switch senses the pressure differential and when it reaches a pre-set level, the self-cleaning process begins.
Amiad’s ADI-P controller offers a one-of-a-kind monitoring and control functionality. The controller interacts with Amiad’s advanced, user-friendly app that provides detailed filtration performance data on your mobile phone device. The self-cleaning mechanism is controlled and monitored by the ADI-P controller. The self-cleaning cycle is triggered by an integrated DP switch. The ADI-P controller and mobile app also provide:
- DP and flush cycle counters
- Alerts – low/high pressures, low battery
- Reports and performance history data
The self-cleaning cycle is initiated by any one of the following conditions:
1. Signal from the DP switch, pre-set at 7 psi (0.5 bar)
2. Time interval parameter set at the controller
3. Manual start, triggered by the ADI-P mobile app (within Bluetooth range) or via electronic controller keypad
The flush valve opens to atmosphere creating a strong suction force at the scanner nozzles, effectively removing dirt particles from the screen and discharging them from the filter.
