Worth knowing before you order
This is the chemically resistant option in the range: PTFE-coated head and diaphragm with FFPM valves, two stages, 20 mbar absolute ultimate vacuum and 20 L/min at atmospheric pressure. Note that the ultimate vacuum is quoted in mbar absolute here and in MPa on the smaller oil-free pump, so the two cannot be compared as printed without converting one of them. Tubing connects at 10 mm and the standard accessories are the pump, the manual and the test certificate only - no tubing, trap, gauge or exhaust filter. Noise is quoted below 70 dB, which is audible on an open bench.Specification
