Compressed air: A 6 bar g compressed air supply is required; where this is unavailable an optional compressor can be supplied with the unit (at extra cost). Electrical requirements: 400 V 3-phase 50 Hz. A fused isolator of the correct rating must be incorporated in the supply line as near as possible to the unit. Information on the installed load for each individual unit will be supplied by Spirax Sarco.
