The MACH

The "MACH" bar screen is a package of mechanical chain operated bar screen previously which is known as CHFF, CHFB & CHFFM. For over last two decades, The "MACH" which is front raked, front/back return bar screen, is the standard for the industry with proven reliability. The "MACH" provides protection for the processing equipments by removing oversize debris from the sewage.

Chain operated cleaning rakes intermesh with the bar rack, and elevate collected debris to a discharge point where each rake is wiped off before descending on the return side of the unit.

Fairfield provides mainly three models under The MACH:


MACH-01 CHFF - Chain Operated Front clean Front return

»  MACH-01 is mainly applicable where front cleaning system is required and inclination angle with respect to vertical is 6° to 15° .


MACH-02 CHFB - Chain Operated Front clean Back return

»   MACH-02 is mainly applicable where back cleaning system is required and inclination angle with respect to vertical is 6° to 30°.


MACH-03 CHFFM

»  MACH-03 is mainly applicable where we want to go for the fine screening, gap between bars up to 4 mm, with less capital cost.


MACH-04 CHBB

»  MACH-04 Bar Screen can be inclined from 15° to 30° from the vertical. It has chain operated cleaning rakes which descend on the downstream side of the bar screen, turn around the foot sprockets, engage the bar screen at channel floor level, and ascend on the downstream side of the bar screen.

Involuntary Squeeze Protection

»  The main eye-catching feature of Fairfield MACH-03 bar screen is involuntary squeeze protection. This feature enables automatically clear obstruction. Sensor provided in equipments senses the obstruction and change the rake direction. This direction changes either successfully dislodged the obstruction or repeat the process in forward direction. Cycle will repeat for a fix number of time and afterward machine will automatically shut off.
