When the young engineer Ernst Thielenhaus constructed a new, particularly compact diaphragm compressor in 1948 and named it HANDY, he anticipated what would happen decades later in mobile telephony: He reduced technology - in this case the production of compressed air dimensions and weight so much that it was easy to transport and use anywhere. More than 40 years later, the marketing strategists of the mobile phone manufacturers adapted the catchy name.

With the HANDY K1, Koellmann Airtec offers a lightweight diaphragm compressor with a piston, which is particularly suitable for mobile applications.

The two-headed membrane compressor HANDY K2 by Koellmann Airtec is characterized by its robustness and a large output range.

With the HANDY V1, Koellmann Airtec offers a lightweight vacuum pump with a piston, which proves its worth especially in mobile applications.
