Field Filtration/Sampling Dry Vacuum Pumps

• Powerful, Portable, & Economical
• Lab or Field Usage
• Advanced Chemical Resistance

Quiet GEMINI pumps use DC motors powered by an AC adapter unit in the lab or a 12 VDC adapter for your vehicle. Pump fumes up to 13L/min and can achieve vacuum to 190 Torr. GEMINI gives you enhanced chemical resistance - tolerant beyond aqueous fumes for use with solvents and weak acids/bases.

GEMINI’s high performance components will not corrode. Chemical resistance is built in with polyarylamide heads and Viton diaphragms, tubing, and valves. The oil-free dry pump design provides top performance in a portable durable package.

For convenient vacuum readout and regulation, order Model 2060.
