The automatic change-over unit enables an uninterrupted gas supply from 2 groups of cylinders or bundles to a pipeline system.

The changing-over to the secondary supply side is automatic when the primary supply side is depleted.

The only manual operation is to reset the unit by moving the lever when the empty cylinders or bundles are replaced.

Specially designed for acetylen, from 2x1 to 2xn cylinders or bundles, this changeover unit is suitable for industrial applications needing a high volume of acetylen (welding, cutting...).
