ProBoost Diffusion Pump

• Deeper Vacuum for Final Drying on a Schlenk Line
• Increases the flow and decreases the vacuum pressure of a vacuum pump
• Reach 2x10⁻⁵ torr ultimate vacuum
• Easily attaches to a Rotary Vane Pump

Welch’s ProBoost is an air cooled gas jet pump (commonly called a diffusion pump). The gas jet is formed by directing boiling silicone vapors thru a hollow cone. Since there are no internal moving parts, the pump is very simple. The pumping action commences when the vacuum pressure goes below 0.2 Torr (200 millitorr). On an empty, leak free system, ProBoost backed by a rotary vane pump lowers the vacuum pressure to 0.00002 Torr (20x lower in pressure than a 2‐stage rotary vane pump can do alone).

Automated shutdown process works through an embedded control board that disables heater and enables fan during shutdown.

*ProBoost comes with NW50 clamp, NW50 centering ring, NW25 clamp, NW25 centering ring, line cord, cooling fan, switch, and 100 ml of Welch ProBoost Silicone Oil, Cat. No. 1391K. Pump connection kit is required to connect a ProBooster to a rotary vane pump.
