Opening of Manufacturing Facility

Opening of Manufacturing Facility

To celebrate the opening of the new manufacturing facility of de Graaff Engineering, we had a “Tag der Offenen Tür” or open days on the 12th and 13th May 2017. The new facility enables us to build and test high speed machinery in clean-room conditions. Also the installation of a 1.5t crane later this year will allow us to build larger machines like the upcoming 150 kW 38,000 rpm, gas-bearing supported, Helium gas compressor at the end of this year. Besides a tour of the facility and demonstrations of our capabilities where lots of home baked cakes and refreshments. These together with good conversations and many new connections made the weekend a success for us.

Gas blower developments

Gas blower developments

We are pleased to announce a close cooperation with OFTTech Ltd. to develop oil free gas blowers. These blowers are perfectly suited to H2, He, N2 and a variety of other gasses. Such blowers are critical in applications where no oil vapour is allowed into the gas stream and a complete seal is required. Contact us to discuss your requirements.
