Low pressure automatic filter

Product catalog summary

Overview
The Hectron AS series automatic filters are designed for low-pressure applications and feature a self-cleaning system activated by pressure difference. They are suitable for various water networks, including those with minimal pressure.

Key Features

No minimum pressure requirement
Low water consumption during cleaning
Fully automatic operation
Delivered fully equipped
Available for high flow rates

Filtration Process
Filtration is achieved using a cylindrical screen. When the screen clogs, a pressure switch detects the pressure difference and initiates the cleaning cycle.

Cleaning Mechanism
Cleaning is performed by a water spraying arm using pressurized clean water from the filter outlet. The arm rotates to clean the entire surface in one cycle. A solenoid valve opens at the end of the cycle to drain suspended solids.

Technical Specifications

Cleaning with water spray at over 3 Bar
No external water supply needed
Built-in pump and control system
Filtration degree down to 60 microns
