Today's high-range pressure controllers demand precision, speed, and stability—yet available pneumatic sources have largely remained stuck in the past. Nitrogen cylinders are cumbersome, costly, and pose serious safety risks with high-pressure storage and handling. Manual pumps waste valuable technician time on constant charging, venting, and refilling, pulling focus away from the actual calibration work. Worse still, conventional air compressors introduce vibration, noise, and moisture that degrade controller accuracy and shorten equipment life.

The Additel 705 is purpose-built to close this gap. It delivers a wide pressure range from -0.95 to 85 bar (-13.8 to 1230 psi), integrating both positive-pressure and vacuum outputs in a compact, all-in-one pneumatic source designed to seamlessly complement high-range pressure controllers. Its parallel dual-pump-head design enables fast pressure generation with smooth start/stop and rapid response, keeping pace with the demanding duty cycles of modern controllers. Low-noise performance suits even the most sensitive laboratory environments, while modular construction allows quick on-site maintenance without specialized tools. Fully automatic intelligent liquid drainage protects internal components and downstream devices—no manual intervention required.

Finally—a pneumatic source engineered for the performance, safety, and efficiency that today's metrology demands. No more cylinders. No more hassle. Just reliable, quiet, and intelligent pressure generation.
