1. General data
1.1. The present manual is a document, containing the specification of the compressors
(hereinafter referred to as compressor) SB4/C-100.LB75, SB4/F-270.LB75, SB4/F-
500.LB75, SB4/F-270.LB75V (air compressors, piston-type compressors), as well as the
maintenance guidelines and technical characteristics, the adequacy of which is ensured by
the manufacturer.
1.2. The manufacturer has the right to make some minor constructive changes, which
may be not stated in this document.
2. Purpose
2.1. The compressor is a complex electromechanical production, which serves the pur-
pose of compressed air supply to the pneumatic systems, devices and instruments, used in
industry, automobile service centers and for other consumers’ purposes, after its rectification
with the auxiliary air treatment system, and adjustment to the standards, peculiar to each
branch. The compressor helps to save electric energy, to mechanize labor and to improve the
quality of production.
It is not allowed to use the compressor in the areas of high risk of explosion or fire ac-
cording, in the places, exposed to rain, and for household purposes.
2.2. The power supply of the compressor is provided by means of an alternate current
power supply source with the voltage 400 V and the frequency (50 ± 1.25) Hz.
2.3. The climatic construction – NF 3.1, by the ambient temperature 274 – 313 K (from
+1 up to +40 ºC).
2.4. The compressor’s operating mode – intermittent.
2.5. Pressure regulation in the receiver – automatic.
2.6. The compressor has a thermal protection against the equipment overload (thermal
relay), short circuit or fault of one of the phases of the electricity supply network (automatic
cutout).
2.7. The compressor can be additionally equipped with a water and oil segregator.
2.8. The general view of the compressor is presented on pictures 1, 2, 3, 4, and the prin-
cipal electric scheme – on picture 5.
3. Performance specifications
3.1. The general safety requirements, concerning the compressor’s design and electric
equipment comply with EN 1012-1; EN 60204-1.
3.2. The compressor’s receiver is designed and manufactured in compliance with the
Directive of EEU Council "Certification of vessels under pressure 87/404/ЕEU".
3.3. The main technical characteristics of the compressor are listed in table 1.
3.4. The compressor’s electrical equipment is made with protection level not less than
IP41.
