Back-flush Controllers

Talgil — an autonomous solution for reliable and accurate filter back-flushing, up to 30 filters per unit.

Talgil back-flush controllers operate automatic filters and filter batteries by time, pressure differential (DP) or both, with automatic fall-back to time on a continuous-cycle fault. AC and DC models cover a single filter up to 30 outputs.
