Atlas Copco's L-range of durable piston compressors,designed for reliable continuous duty and minimummaintenanceThe oil-free LF-Snow and oil lubricated LE-Snow piston compressors are based uponthe established Atlas Copco L piston range, designed for extended continuous dutyoperation.This is made possible by the use of high quality materials, an innovative design inadapting the units for operation in the extreme conditions encountered within themountain environment.L compressor blockUnique and simple to service, Atlas Copcopatented stainless steel flexible inlet/outlet disc valves.Rapid replacement, large surface airintake filter - reducing contaminants andprolonging compressor life.High capacity cooling fan containedin protective fan cowl, givingoptimal cooling and safe operation.Venturi silencing intake for low noiselevels.Finned die-cast aluminium outletcooler for single stage units orinter-cooler and after-cooler fortwo stage units.Die-cast aluminium crankcase andfinned cylinder heads give high coolingcharacteristics resulting in long lifetimeand efficient operation.Non return/unloading valve ensures unloadedstarts and longer motor life.(Only on versions with unloading valve).Sound muffler maintaining low noise levelsduring compressor unloading.

LE/LF-Snow rangeHigh quality oil-free piston compressorsFollowing features and benefits arebuilt into the L Snow range- Aluminium alloy construction of majorcomponents give low overall packageweight.- The unit can operate without interruptionat high angles of inclination, often experiencedin snow making applications.The oil carry over levels for the LE-Snow compressors arevery low (< 0.1 g/kW/h) making the units ideal for continuousduty, mainstream applications and in combinationwith Atlas Copco quality air products - DD/PD filters, FDrefrigerant and CD adsorption air dryers - give the possibilityof high quality air packages for more sensitiveapplications.The LF-Snow piston range from Atlas copco includesealed for life main bearings, nickel plated cylinders andteflon coated anodized aluminium pistons. This uniquecombination of materials applied to the proven AtlasCopco block design gives you:- guaranteed no oil in the system- an oil-free unit designed for continuous duty withlow maintenance- a perfect alternative to oil lubricated compressorsfor mainstream applications, or combined with AtlasCopco quality air products offers the best value,highest quality, small capacity compressed airpackage on the market today.- Specially designed air inlet and outletsystem allowing trouble-free operationwithout compressor freeze up in extremelow ambient temperatures. Thisalso avoids ingress of snow-moisture intothe compression system during periods ofheavy precipitation.- Direct driven operation by IP 55 electricmotor giving extended lifetime andcoupled with V-piston arrangement, lowvibration.- Durable internal components givingtrouble-free operation with minimummaintenance.- LF-Snow compressors have an 100 %oil-free operation giving an environmentallyfriendlier solution than oil-lubricatedalternatives and avoiding the need for oil'top-up' during operation in isolatedlocations.- Normal working ambient temperaturefrom -25° to + 5 ° C / -13° to 41° F.
