Where cylinders are supplied directly from a compressor, not only will product quality be optimised by controlling the inlet pressure for the application with a general-purpose pressure regulator, but energy costs can be reduced by up to 30 per cent by using double-acting cylinders where a reduced pressure can be achieved on the non-working return stroke.
