manualfor pressure and vacuum

Overview
The ADDITEL ADT 914 pneumatic pump is a manual pressure generator and controller covering -0.95 bar up to 25 bar (375 psi). The fine adjustment screw allows pressure tuning to 0.1 mbar. The pump features a shut-off valve for high stability and reduced maintenance interventions. Two manual-tightening connections enable connection and disconnection of gauges without PTFE tape or wrenches. It is suitable for calibration of transmitters and gauges, on-site or in the laboratory.
