DELIVERING WORLD CLASS Compressed Air Solutions SCREW SET ENTIRELY DESIGNED AND MANUFACTURED BY ROTAIR WITH GROUND PROFILE OF ROTAIR EXCLUSIVE PATENTED MANUFACTURE AND DESIGN FOR OWN USE AND B2B APPLICATIONS. The asymmetric profile with oil injection is created by means of high pressure grinding that ensures excellent performance of the set in the compression stage, reducing the required energy dispersion to a minimum. The installed screw sets are of direct transmission type without geared rev multiplier. This solution reduces wear of the screw set and overheating, ensures reduced noise...

BLASTING MODE AFTER COOLED SANDBLASTING All models of ROTAIR compressors have specific aftercooled versions. They feature an additional cooler to cool down compressed air and a specific condensate separator, that drains the water produced by the thermic exchange of the cooler. This gives a cooler output of compressed air (ambient +12 ± 2°C) and significantly lowers the humidity of the air, although not removing completely the moisture from air, as this depends mainly on the environmental conditions.

INBUILT ADDITIONAL COOLER AND SPECIFIC CONDENSATE SEPARATOR for cool and dry air The aftercooled versions are called “SANDBLASTING” because the main use of these machines finds its operation in the sandblasting sector. These machines are indicated for all operations that are sensitive to humidity of the air output: optic fibre laying, use of pneumatic tools that are sensitive to humidity. ROTAIR also offers an EXTERNAL “BS” AFTER-COOLER SYSTEM, easy to connect through an air pipe kit and is electrically powered by the compressor. It enables standard compressors, from 2000 to 8500 lt/min (71...

ROTAIR OFFERS A BROAD PANEL OF TRAILERS, TO MAKE COMPRESSORS EFFECTIVELY PORTABLE. The undercarriage of a portable compressor is composed of: The part connecting compressor to the ground, includes suspension system, wheels and all related parts. Suspensions can be assured with springs (sprung axle) or leaf springs (leaf spring axle). Wheels are of different size, to match the weight of the machine and according to the type of towing. The drawbar is the rigid connection between compressor and towing vehicle. It can be at fixed height (gooseneck bend or straight angles) or adjustable through...

FEATURED HIGHLIGHTS EXCLUSIVE ROTAIR INTELLIGENT SYSTEM THE “INTELLIGENT SYSTEM” ENABLES A PREHEATING OF THE ENGINE WITHOUT OVERLOADING IT, THE AIREND WILL START WORKING ONLY WHEN THE PERFECT CONDITIONS ARE REACHED. THE SAME IN TURNING OFF THE MACHINE AFTER A DEPRESSURISATION PHASE OF THE HYDRAULIC CIRCUIT, NO HAMMERING OF THE AIREND DUE TO ITS INERTIAL MOVEMENT, BUT A GRADUAL TURN-OFF. No more need to start the machine with the air exit open (and risks of forgetting it) All this brings: › A correct lubrication to the screw set and the engine, even in extremely cold temperature conditions....
