Ventilek advises: The 4/90 model is a "little giant". With a displacement of 650 liters per minute, it can easily handle demanding pneumatic tools, but it won't take up half your workshop. The fact that they assemble it by hand in Chrást and give it a 5-year warranty is clear proof that this is not some "quick Chinese fix", but a proper Czech workhorse!

A domestic company of world quality
One of the leading companies operating in the field of compressed air not only in the Czech Republic, but also in the world, is the domestic manufacturer ATMOS Chrást s.r.o., which presents itself mainly by the production of screw and piston compressors, screw blocks and motor generators. The roots of the company go back to 1899, when foundries and machine shops were established in the West Bohemian village; during the communist regime, the machine shops belonged to the national company Škoda Plzeň. It was at the end of this era that the company began licensed production of screw blocks and screw compressors, which became very popular over the years due to their reliability. Since then, ATMOS has come up with more than 25 new compressor types - creating a range of mobile, locomotive or stationary compressors that are subject to the most stringent global standards, adding the hallmark of honest design that is so much a part of ATMOS even in today's consumer age.

A product offer for everyone
ATMOS is constantly working on new compressors and the characteristics are subject to regular technological research. As a result, the company has already come up with innovative ideas on several occasions, such as when it extremely reduced the noise level of stationary compressors without losing their top performance parameters, thanks to which they have been widely exported abroad. However, in addition to large companies, ATMOS also meets the needs of private customers with smaller workshop machines. Another breakthrough was the creation of the small and compact Albert compressors, whose product range is constantly expanding and are suitable for hobby use. More than 60 of these types are currently in production, with outputs ranging from 3 to 22 kW. The company is the youngest to launch motor generators, filling one of the gaps in the domestic market.
