The construction industry uses ready mixed mortar and plaster for „cladding“ walls. Hereby the dry mortar is mixed with water in a special machine and sprayed onto the wall by compressed air.
There will hardly be any manufacturer of plastering machines in the world who does not know of the diaphragm compressor Handy K2 from Koellmann-Airtec.
After its development in 1948 the compressor was relegated to a niche existence, but with the breakthrough of the construction industry at the beginning of the 60ies the „wallflower“ became an absolute match winner. In the mean time tens of thousands of compressors have been installed into plastering machines for generating oil-free compressed air and are considered to be the most reliable appliance in this sector.
The compressor, of course, can also be used for a multitude of other tasks within industry, handcraft, workshops, and labs as well as construction sites. Its extremely rigid design allows the Handy to be installed in a machine or to be used as a stand-alone unit, which will work reliably under ever changing conditions.
