Amiad Mini Sigma 50mm Fully Automatic Self-Cleaning Screen Filter with ADI-P Bluetooth DC Controller - 1200cm² (145-500LPM)
Amiad Mini Sigma 1200cm2 50mm (2") Automatic Filter C/W ADI-P Bluetooth DC Controller
The Amiad Mini Sigma 50mm Self-Cleaning Screen Filter is a compact, durable, and fully automatic filtration system designed for agricultural and landscape irrigation. Engineered from corrosion-free polymeric materials, the Mini Sigma is lightweight yet robust, offering reliable protection for irrigation systems while minimising water and energy consumption.
Using Amiad’s patented suction-scanning cleaning technology, the Mini Sigma consumes less than 1% of the process water while achieving 100% cleaning of the screen area — the lowest flush ratio in the industry. The filter’s modular design allows for flexible installation, whether on-line, angle, horizontal, or vertical, making it suitable for diverse field conditions.
Equipped with the innovative ADI-P Bluetooth DC Controller, the Mini Sigma provides advanced monitoring and control through a mobile app. The controller logs flush cycles, monitors differential pressure (DP), issues alerts, and provides detailed performance data, all accessible via smartphone within Bluetooth range.

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.
