Oil-free diaphragm vacuum pump for laboratory vacuum filtration, degassing, drying, extraction support, and small instrument vacuum/pressure supply. This variant is configured as positive/vacuum operation with adjustable vacuum and flow.

The oil-free diaphragm design avoids oil mist contamination and reduces routine maintenance compared with oil-sealed pumps. Use a trap or buffer bottle when handling moisture, solvent vapor, particles, or corrosive samples.

Technical specifications:

Use: Suitable for Buchner filtration, vacuum desiccators, solid-phase extraction manifolds, rotary evaporator support where the pressure requirement is compatible, degassing, and general laboratory vacuum/pressure tasks.

Operation notes:

- Use on 220V/50Hz power. Check tubing, fittings, and receiving vessels before starting.

- Do not block the inlet/outlet. Do not use positive pressure and vacuum ports against each other at the same time.

- For wet or solvent-heavy work, protect the pump with a suitable trap and keep liquid out of the pump head.

Storage: Keep dry and clean after use. Store at room temperature away from corrosive vapors and direct splash.
