Product detailed description
ATMOS Perfect 5.5/270 industrial piston compressor (5.5 kW, 400 V)
Looking for maximum performance and stability for your production? The ATMOS Perfect 5.5/270 is a robust, slow-running workhorse designed for demanding industrial applications[cite: 4]. Thanks to the combination of a powerful three-cylinder LB 75 compressor unit and a voluminous 270l air receiver, this machine is an ideal choice for paint shops, tire services, and assembly workshops, where a high air reserve and reliability are required even in continuous operation[cite: 4, 6, 16].
What makes the ATMOS Perfect 5.5/270 stand out?
- ✅ Record-low speed: The unit operates at just 950 rpm. This design minimizes wear, reduces temperature, and ensures extreme bearing life.
- ✅ Manual assembly and supervision: Each compressor has its dedicated mechanic who personally assembled it and is responsible for its top quality and output tests[cite: 32, 33].
- ✅ Three-cylinder heart LB 75: The cast-iron unit with a 'W' arrangement offers perfect balance, smooth operation, and high energy conversion efficiency[cite: 16, 17, 20].
- ✅ Suitable for heavy-duty operation: The robust construction allows deployment in demanding installations, such as biogas plants[cite: 6].
- ✅ 60-month warranty: For the reliability of the Perfect series, the manufacturer ATMOS Chrást provides an unlimited five-year warranty[cite: 36, 37].
- Cast iron durability: Three-cylinder block made of high-quality cast iron designed for continuous operation[cite: 15, 16].
- Automatic regulation: Economical start-stop operation by a branded pressure switch[cite: 22].
- Protection and Safety: Motor overcurrent protection and a complete set of safety fittings[cite: 14].
- Aftercooler: Standard equipment for effective reduction of air temperature and humidity[cite: 13].
- Quiet operation: Massive cast-iron block combined with low speeds effectively absorbs noise.
- Optimal Cooling: Large fan and generously dimensioned cooling fins[cite: 13].
- Drive: V-belt designed for maximum lifespan of motor and unit bearings[cite: 12].
- 270 l air receiver: Large tank volume minimizes switching frequency and saves the motor[cite: 4, 41].
- Service comfort: Open design ensures quick access to all key parts[cite: 24, 25].
- Czech tradition: Quality proven by thousands of installations in the Czech Republic and abroad[cite: 36].

The valve recommends: The 5.5/270 model is an "immortal workhorse" for me. The three-cylinder LB 75 unit runs at only 950 rpm, and with the 270-liter air receiver, the engine has plenty of time to rest. The fact that these machines also run in biogas plants speaks for itself. With a five-year warranty and honest Czech cast iron, you simply have peace of mind for decades of work!

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.
