FOUR E's Scientific Vacuum Pump 50L/Min with Switch, Oilless Lab Pump with Vacuum Meter, Aluminum Silencer and 4 Connectors, for Laboratory, Electronics, Industry

FOUR E's Scientific Oilless Vacuum Pump is a clean, low-maintenance essential for laboratory applications, designed to deliver reliable vacuum pressure without oil contamination risks. It adopts a diaphragm-based operating mechanism, eliminates oil spills, residue buildup, and frequent oil changes, ideal for sample filtration, degassing, vacuum drying, and rotary evaporator setups. Lab vacuum pump is compact and quiet, operates smoothly with minimal noise, fitting seamlessly into benchtop lab spaces. Equipped with overheat protection and a durable corrosion-resistant housing, it ensures stable performance for prolonged use.

• Package Included: You will receive 1 vacuum pump with 4 rubber feet, 1 vacuum pressure gauge, 4 quick connector (Inner diameter 6mm/8mm/10mm/12mm), 1 gauge connector, 1 silencer, 1 PTFE tape (wrapped around the connection to prevent air leakage), 1 plastic tube (39.37 in) and 1 instruction manual.
• Oil Free & Maintenance Free: Upgraded version with on/off switch, no need to unplug the power cord frequently. After connecting the power supply, turn on the switch on the power cord. Oil free vacuum pumps can operate without any lubrication, reducing maintenance issues and significantly increasing production.
• Silence Vacuum Pump: Aluminum alloy silencer not only reduces the noise generated during use to a greater extent, but also comes with a silencer to provide you with a quieter working environment ≤57dB. Electric vacuum pump is suitable for laboratory environments, enabling you to remain focused and meticulous during your work.
• Compact Oilless Pump: Laboratory vacuum pump is craft with sturdy material, compact and exquisite. Its simple and clear industrial style makes it very convenient to use. The installation can be completed quickly by following 3 steps. First, install the quick-connect fitting on the port labeled "INTAKE", then install the muffler on the port labeled "EXHAUST". Finally, there is an additional port on the side for installing a pressure gauge. Wrap the threads with 1-2 layers of raw tape before installing.
• Multi-purpose Vacuum Pump: Compared with traditional oil vacuum pumps, diaphragm vacuum pump offers a completely oil-free and clean vacuum environment, completely avoiding the contamination of oil vapor from oil pumps. Suitable for vacuum pressure requirements in the aerator, nitrogen blower, thin layer color developing spray, solvent filter, air sampler, lab equipment, cosmetic equipment, etc.
