Why Backflush Controllers

Modular controller is expandable from 1 to 10 outputs. Adding more outputs is quick and easy – no tools required.
Can be used with automatic disc filters, automatic sand media filters and automatic screen filters.
Flush cycle is triggered by time or pressure differential and each type of flush cycle is logged by the controller.
Design flexibility with an embedded pressure differential (PD) gauge or an external PD gauge.
Detection of continuous backflush cycles causes an alarm to sound.
User-friendly LCD display and keyboard.
Ability to manage a downstream pressure sustaining valve.
Flexible settings for pre-dwell, dwell and flush times allows programming to meet system requirements.
