2 Preliminary machine information
2.1 General description
The rotary screw compressor has been specifically designed aiming at minimising maintenance and labour costs.
The outside cabinet is completely covered in sound-proof and oil-proof panelling thus ensuring its extended and lasting wear.
The components have been arranged so that all vital parts can be easily reached for maintenance purposes
simply by opening dedicated panels with quick-release locking devices.
The filters and adjustment and safety devices (oil filter, air filter, oil separator filter, regulator valve, minimum
pressure valve, max. pressure safety valve, thermostat, belt tightener, screw compression unit, pressure
switch and oil separator tank emptying and filling taps) are all fitted on the same side.
Note! The tanks of the compressors have been manufactured in compliance with the EEC/
404/87 Directive for the European market. The compressors have been manufactured
in compliance with the EC/37/98 Directive for the European market.
Note! Check your model on the identification nameplate fitted on the compressor. It is also
indicated in this manual.
ADVISED LUBRICANTS
Always use oil for turbines with approximately 46 cSt at 40°C and a pour point of at least -8 +10°C. The
flash point must be greater than +200°C.
The oil in rotary screw compressors has the function of lubricating and cooling the screw unit. The oil also
has a sealing function to ensure a perfect compression seal within the block.
Therefore it is extremely important to choose the correct type of oil for this type of compressor.
NEVER MIX DIFFERENT OIL QUALITIES.
SCREW OIL FOR DR/SD VERSIONS
FIAC SYNT/RS D 46
OR IN ALTERNATIVE
SHELL CORENA AS46
MOBIL RARUS SHC 1025
OR 100% SYNTHETIC OIL WITH THE SAME TECHNICAL CHARACTERISTICS AS THOSE LISTED
ABOVE
Use oil with VG32 rating for cold climates and VG68 for tropical climates.
It is advisable to use synthetic oils for very hot and humid climates.
2.2 Intended use
The silent rotary screw compressors have been designed and manufactured exclusively to produce compressed air.
EVERY OTHER USE, DIFFERENT AND NOT FORESEEN BY ALL INDICATED, RELIEVES THE
MANUFACTURER OF POSSIBLE CONSEQUENT RISKS.
In any event the use of the compressor different to that agreed in the purchase order RELIEVES THE
MANUFACTURER FROM ALL LIABILITIES WITH REGARD TO POSSIBLE MATERIAL DAMAGE AND
PERSONAL INJURY.
The electrical system is not designed for the use in environments subject to explosion or for flammable products.
NEVER DIRECT THE JET OF AIR TOWARDS PEOPLE OR ANIMALS. NEVER USE
THE COMPRESSED AIR PRODUCED BY LUBRICATED COMPRESSORS FOR
RESPIRATORY PURPOSES OR IN PRODUCTION PROCESSES WHERE THE AIR IS
IN DIRECT CONTACT WITH FOODSTUFFS UNLESS IT HAS BEEN FIRST FILTERED
AND CONDITIONED FOR SUCH PURPOSE.
