Product Features

• Main applications:

  ● Vacuum filtration ● Solvent purification ● Vacuum distillation
  ● Vacuum drying ● Air sampling ● Cell culture
  ● Compression and gas exchange ● Colloidal drying ● Solid phase extraction

  characteristic:
  This product does not require any working medium (oil-free) to generate a clean vacuum, does not produce pollution, and uses new technologies and materials in the production process.
  ▲ Low noise design, good environmental performance, quiet, micro vibration.
  ▲ Easy to carry, convenient to move, and smooth to work. Adopting oil-free lubrication and piston structure, it has a longer service life than ordinary diaphragm pumps.
  The pump body motor adopts a copper motor with better tolerance performance, which can ensure long-term continuous operation and running.
  Unique pressure adjustable design that can meet a certain range of vacuum degree and gas flow rate.
  ▲ Adopting imported bearings, smooth operation, no noise, long service life, and high work efficiency.
  The body shell is made of alloy material through integrated die-casting, ensuring a clean appearance and heat dissipation performance.
  ▲ All models come standard with anti-corrosion air filters to prevent damage to pump body components from corrosive gases, effectively preventing corrosion.

  usage method:
  1. Connect the power supply. Connect the vacuum tube at one end of the anti-corrosion air filter to the suction nozzle of this vacuum pump, and start the power switch of this machine. When the pump body is running smoothly, connect the vacuum tube at the other end of the anti-corrosion air filter to the pressure reducer, and then start working.
  When stopping work, first turn off the power switch of the vacuum pump, loosen the pressure regulating knob, and wait for the pressure reducer to return to normal pressure before separating the connecting pipe between the pump and the pressure reducer.

  
  Exception handling:
  ● Disconnect the power supply.
  Please do not attempt to disassemble any part of the pump without disconnecting the power supply to avoid danger.
  Wait for the pump to cool down.
  Please contact the manufacturer or distributor for further assistance.
  The motor of this product is equipped with an overheat protector, ensuring that the product will not be damaged due to overheating or overload. After cooling, the automatic starting device will restart the pump, so there is no need to worry.

  Product installation:
  Please refer to the technical parameter table for detailed parameters.
  Please disconnect the power supply before installation or maintenance to avoid danger.
  Do not allow the machine to come into contact with water or other organic solvents, and be sure to protect the machine.
  Ensure ventilation and smoothness of the product.
  Do not put any items into the ventilation opening to avoid danger or damage to the instrument.
  After prolonged machine operation, do not touch the machine casing to avoid burning your hands.
  This product does not require any lubricating oil, and the sealed bearings are permanently lubricated.
  Install pipes that match the pump inlet.

  Product placement:
  To reduce noise and vibration, the product can be placed on a shock-absorbing device, which can reduce resonance.
  Do not obstruct the circulation of air and affect the normal use of the pump.
  Connect the power supply correctly and turn on the power switch.

  Product usage:
  This product can only be used for air filtration.
  Corrosive liquids or particulate materials are prohibited from entering the pump body, and oil pollutants or other liquids must be pre filtered.
  The working environment temperature should not exceed 55 ℃
  This product cannot be used at high altitudes, as low air pressure at high altitudes can affect the product.
  The product belongs to precision instruments and is prohibited from strong vibration, dirt and moisture.
