Product detailed description
Industrial piston compressor ATMOS Perfect 4/PFT (4 kW, 400 V)
Are you looking for maximum performance from a piston unit for integration into your technology or connection to an existing central air receiver? The ATMOS Perfect 4/PFT is a professional, slow-running cast iron compressor supplied on a base frame without a pressure vessel[cite: 40]. This machine is equipped with a high-performance two-cylinder LB 50-2 unit and is designed for demanding daily operation in industrial workshops and assembly lines[cite: 4, 16].
Why choose the Czech quality of the Perfect 4/PFT series?
- ✅ Manual Assembly and Supervision: Each individual unit has its dedicated mechanic who personally assembled it and bears direct responsibility for its quality[cite: 32].
- ✅ Top-tier LB 50-2 Unit: Two-cylinder cast iron V-design with high energy conversion efficiency[cite: 16, 17, 45].
- ✅ Extreme Reliability: Slow-running concept (only 1100 rpm) ensures minimal wear and long bearing life[cite: 12, 19, 45].
- ✅ Proven in Practice: These machines reliably operate even in continuous processes, for example, in biogas plants[cite: 6].
- Professional Workhorse: A high-quality cast iron unit designed for continuous deployment[cite: 4, 15].
- Economical Regulation: Automatic start-stop operation by a branded pressure switch[cite: 22].
- Safety and Protection: Motor overload protection and high IP54 rating[cite: 14, 45].
- Optimal Cooling: A large fan circulates air through generously dimensioned cooling fins[cite: 13].
- Low Noise Level: The massive cast iron block combined with low speeds effectively dampens noise[cite: 19, 30].
- Integrated Aftercooler: Standard equipment for reducing air temperature and humidity[cite: 13].
- Belt drive: Design engineered for maximum stability[cite: 12].
- Space saving: The PFT frame version is ideal for installations in confined spaces[cite: 4, 40].
- Five-year warranty: ATMOS Chrást provides an unlimited 60-month warranty on this machine[cite: 37, 55].
- Serviceability: Open design allows for quick access to all parts[cite: 24].

Valve recommends: The 4 kW PFT version is for me a 'pro hidden in a frame'. It is the ideal choice if you already have a large air receiver in your workshop or are building your own air distribution system. You get an honest Czech cast-iron heart with a five-year warranty, which, thanks to its low speed, will not get tired easily!

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.
