GOYOJO Lab Vacuum Pump, 15L/min Oilless Diaphragm Vacuum Filtration Pump with Adjustable Flow & Dual Pressure, Portable Oil-Free Laboratory Pump with 2 Hoses for Filtration, Distillation & Extraction

Oil-free negative pressure vacuum pump is a fully oil-free lubricated air compressor with pure compressed air and large exhaust volume. This oil-free vacuum pump has a wide range of applications and can be used with a variety of equipment, such as nitrogen blowers, solid-phase extractors, thin-layer color development sprays, solvent filters, atmospheric samplers and so on, to meet a variety of vacuum or positive pressure requirements.

Product features

DC adjustable-speed motor: adopts DC adjustable-speed motor, diaphragm-sealed gas chamber to ensure unidirectional flow of gas, double gas chambers work in series, high vacuum degree.

Non-oil pump design: relative isolation of gas chamber circulation gas, no pollution.

Carrying bag design: the shape design is convenient to use, better heat dissipation.

Surface treatment: electrostatic spraying, uniform color, stronger adhesion.

Vacuum gauge monitoring: real-time monitoring of vacuum, can be positive and negative pressure dual-use (positive pressure can not display pressure, belong to the additional features).

Maintenance-free: free of routine maintenance, long service life.

Operation use:

1. Plug in the power cord and turn on the power switch at the back.

2. Adjust the knob until the pump starts. Adjust the knob to the maximum, the pump works at maximum efficiency.

3. There are two ports at the back, IN and OUT, IN means pumping, OUT means pumping. (Note that the pressure gauge only shows the negative pressure for pumping, not the positive pressure for pumping.)

4. After using the pump, adjust the knob to the left to the lowest, bottle off the back of the power switch. Place in a dry place.
