Edwards E2M18 Two-Stage Rotary Vane Vacuum Pump, 21.6 m³/h Capacity

The Edwards E2M18 is a professionally reconditioned two-stage rotary vane vacuum pump designed for reliable, low-noise operation in scientific, industrial, and laboratory vacuum applications. Featuring a nominal pumping speed of 17.7 m³/h at 50 Hz and 21.6 m³/h at 60 Hz, it achieves a final pressure of 1.5 × 10⁻³ mbar without gas ballast and 1.2 × 10⁻¹ mbar with gas ballast. This pump supports continuous operation with a compact, robust design weighing approximately 39 kg.

Key technical specifications include:

• Positive displacement two-stage mechanism for high vacuum efficiency
• Oil capacity between 1.0 and 1.25 liters ensuring optimized lubrication and cooling
• Inlet and outlet connections compliant with ISO KF25 standards
• Operating voltage range: 100-120 V / 200-240 V and frequency 50/60 Hz
• Noise level: 57 dB(A), suitable for laboratory environments requiring reduced acoustic disturbance

The E2M18 pump is widely adopted in biotechnology, molecular diagnostics, and bioprocessing workflows, essential for vacuum-dependent techniques such as mass spectrometry, vacuum drying, synthetic biology sample preparation, and semiconductor manufacturing. Its ability to handle vapor loads with gas ballast functionality increases operational versatility. This reconditioned unit offers an excellent quality-to-price ratio for research labs, biomanufacturing facilities, and clinical diagnostics requiring a reliable vacuum source.

By integrating this pump into vacuum systems, researchers benefit from enhanced vacuum performance critical in live-cell imaging, fluorescence analysis, and gene editing applications where controlled low-pressure environments are mandatory. The Edwards E2M18 is an indispensable component in advanced biotechnology setups and industrial vacuum infrastructure.
