Vacuum Pump Merchant Video Before installing the quick coupler and gauge, wrap 1-2 turns of packing tape around the threaded connections to prevent air leakage The advantage of Oiless diaphragm vacuum pump Oil-free vacuum pumps have the following advantages: Maintenance free: Oil free vacuum pumps do not require the use of lubricating oil or lubricants, so there is no need for regular oil replacement or lubrication maintenance. This reduces the complexity and cost of maintenance work, and saves time and human resources.No harm: The oil-free vacuum pumps do not produce odors or oil mist, making the working environment cleaner and more comfortable.High quality gas: Due to the absence of oil vapor pollution, oil-free vacuum pumps can provide high-quality gas, suitable for applications with high gas purity requirements, such as electronics, medical, food, etc.Reducing fire risk: Vacuum pumps that use oil may experience oil leakage or oil mist generation during operation, increasing the risk of fire. The oil-free vacuum pump eliminates this risk and improves the safety of the workplace.Wider application range: Oil free vacuum pumps are suitable for a wider range of applications due to their unique design and working principles. They can be used for gas sensitive applications such as analytical instruments, semiconductor manufacturing, biomedicine, etc. Before installing the quick coupler and gauge, wrap 1-2 turns of packing tape around the threaded connections to prevent air leakage Suitable for vacuum clamping for woodworking, provides plenty of vacuum suction to hold woodworking projects, great choice for buchner funnels and roto-evaporators, recommend for small CNC routers Before installing the quick coupler and gauge, wrap 1-2 turns of packing tape around the threaded connections to prevent air leakage Rated Input Power 180W Rated Voltage 110V/60Hz Rated Current 1.6A Recommended Fuse Current ≥5A Vacuum Degree -85Kpa Rated Volumetric Flow Rate ≥ 50L/min Noice ≤50dB Hose Length 1m/3.2ft Capacitance 15μF Thread Type G1/4 Why does the Vacuum pump not running? This oil-free vacuum pump has a mechanism in place to avoid overloads. A machine that works continuously for a long time could automatically switch off due to a high internal temperature. Before restarting the motor, allow it to cool for 15 minutes. Why does a vacuum pump vibrate so much while it's running? 1: the machine is not positioned correctly. Solution: Firmly cushion the machine's four legs; 2: The crank's fixing screw is unsecured. Solution: Tighten the crank's screw. Why is the vacuum pump's output pressure lower than usual? 1: There is an air leak at the machine's air circuit connection. Solution: Tighten the air circuit's connecting pipes. 2: Excessive wear on the piston ring or cylinder. Solution: Replacement of the ring or cylinder on the piston. Do the 50L/Min and 27L/Min vacuum pumps both include a vacuum meter? No! Only the 50L/Min one comes with a vacuum mete. Why is the vacuum pressure not strong enough for me to use it down to -85 kPa? When installing the vacuum gauge and quick-adaptor, the complimentary raw material tape should be wrapped around it before installing it in order to provide a complete sealing effect so that the pressure can reach -85kpa.

Oilless & Maintenance Free Upgraded version with on/off switch, other pumps frequently require an oil change after just 12 hours of use. While our oil-free vacuum pump can operate without any lubrication, reducing maintenance issues and significantly increasing production

Heat-dissipation Design The oilless vacuum pump can operate for more than 24 hours without overheating because to a significant heat-dissipation effect created by double fans and a cooling fin design. Before installing the quick coupler and gauge, wrap 1-2 turns of PTFE tape around the threaded connections to prevent air leakage

Compact & Silence Oil Free Vacuum Pump This vacuum pump is compact and exquisite, with sturdy materials. Its simple and clear industrial style makes it very convenient to use. Equipped with a silencer, it effectively lowers noise during use and improves your working environment

Multi-purpose Lab Vacuum Pump Suitable for aquariums, lab equipment, cosmetic equipment. Additionally, it may be utilized for vacuum pressure requirements in the aerator, nitrogen blower, thin layer color developing spray, solvent filter, air sampler, and other applications
