Cast-iron LB 55-3 pump unit
The LB 55-3 pump unit has 3 cylinders and compresses the air in two stages: first in the large cylinders, then the air is cooled in the intercooler and compressed further in a smaller cylinder. That is why it reaches 12.5 bar and heats up less. It runs at only 1,100 revolutions per minute.
Equipment
- pressure switch with motor overload protection — automatic start–stop operation
- air receiver pressure gauge and safety valve
- air filter on the pump unit intake
- condensate drain cock on the air receiver and ball valve at the outlet
- cooling fins on the cylinders and a large fan on the pulley
- cable with a plug for a 400 V socket
You can add a pressure regulator, compressed air filters and a refrigeration dryer for dry air.
Five-year unlimited warranty
ATMOS gives this compressor a five-year warranty on the whole machine, with no limit on running hours and no service contract. Register the machine within 90 days of purchase and carry out maintenance once a year with an original ATMOS service kit. You record the maintenance in the manufacturer’s app via the QR code from the kit — each record extends the warranty by another year.
Service kits for this compressor
Kits for the LB 55-3 pump unit by service year. The kits for year 1 and year 3 contain oil with an extractor, air filter cartridges and check valve parts; the kits for year 2 and year 4 also contain valve plates, gaskets and a belt.

| Perfect 4T PFT | no air receiver (unit on a base frame) | 4 kW, 400 V / 50 Hz, three-phase | 700 × 430 × 530 mm | 115 kg |
Ventilek says
A horizontal air receiver is stable, and on its wheels the compressor can be moved. Place it so that it has at least half a metre of free space around it — the fan needs to draw in cool air.
You will find all machines of the range in the category ATMOS Perfect piston compressors.

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.
