KNF N810.3 FT.18 Diaphragm Vacuum Pump for Laboratory and Industrial Applications

The KNF N810.3 FT.18 is a reliable diaphragm vacuum pump engineered for precise gas and vapor handling in laboratory and industrial settings. This oil-free membrane vacuum pump achieves a pulsation-free vacuum down to approximately 18 mbar absolute pressure, with a volumetric flow rate of 3.5–4.0 liters per minute, making it suitable for applications such as filtration, vacuum drying, distillation, and sample preparation.

Key specifications include:

• Membrane material: PTFE (Polytetrafluoroethylene) ensuring exceptional chemical resistance essential for hazardous or aggressive media commonly encountered in biotechnology workflows and molecular diagnostics.
• Motor power: 18 W with a standard supply voltage of 230 V, 50 Hz, adaptable per configuration.
• Compact design (170 × 150 × 90 mm) and low noise emission support clean laboratory environments and sensitive analytical setups.
• Lightweight construction at roughly 2.5 kg facilitates portability and easy integration into benchtop systems.
• Maintenance-free and oil-free operation eliminates contamination risks, critical for bioprocessing and synthetic biology research where sample integrity is paramount.

This pump’s design prioritizes clean, contamination-free vacuum generation — a critical requirement across biopharmaceutical production pipelines, gene editing workflows, and various cell imaging or fluorescence analysis applications. The KNF N810.3 FT.18 is widely adopted by researchers and professionals requiring precise vacuum control aligned with biotechnological and clinical diagnostic needs.
