The DFA series cylinders (double-acting version) are of the integral type, i.e. with the fixings incorporated in the heads (front flange mounting). The DFA series is divided into 9 bores for each single and double acting version. This series is only available in a non-magnetic version. The cylinders can also be supplied in "through rod" type (except series DFP).
