This ensures:- that the maximum number of start-ups per hour programmed is not exceeded;- immediate re-starting in order to satisfy a subsequent air requirement.

CSA 20 ENG VOLTA2-03-200511:09Pagina 4Handling Silent RunningHandlingThis series of machines was also designedwith the problem of transport and/or handlingin mind. Accessibility for lifting is allowed onthree of the four sides and easy movementis guaranteed by a careful selection of liftingpoints, positioned so as to obtain a balancedload.Silent runningYears of experience have been applied to the issue of noiselevels with particular care taken in analysing the air flow insidethe machine and the use of suitable panels with anti-noisedevices. The care in assembly of the various components, andthe absence of transmitted vibrations. All have enabled us toachieve results, which put even the standard version of ourmachine at the top of the market.The low noise levels reached allow installation even in workingenvironments or in the immediate vicinity of offices.130110100857560/652040dB (A)
