M315-355 Ingersoll Rand two-stage air compressor

Rotay screw Air compressors.… Reliability at your Fingertips
competing into day's business environment requires manufacturers to keep their operating systems up
and running. when systems go down, production
stops. Reliable, flexible and easy to use equipment is essential for efficient operation.

The Reliability Imperative
Focusing on reliability, Ingersoll Rand rotaryscrew air compressors are designed with aunique, maintenance-free drive system - asimple gear drives the airend. Since themotor and airend are permanently aligned,no adjustments are needed during the courseof normal operation. Additionally, since noinspection covers are required, the geardrive provides a user-safe means of turning the airend.
At the core of Ingersoll Rand rotary
compressors is a rugged airend that uses
duplex tapered roller bearings. These roller
bearings provide linear contact for thrust
loads, dramatically improving airend life.The compressors also incorporate an exclusivebearing coolant dam, assuring that coolant ispresent during the compressor's critical start-upphase, significantly extending the life of thebearings. Used in thousands of compressorsthroughout the world, Ingersoll Rand's airendhas earned a reputation for trouble-free
operation and minimal maintenance.


Superior Features That ReduceOperating Costs
Ingersoll Rand rotary screw compressors add unequalledreliability, efficiency and productivity to virtually anycompressed air system, and could save you 25-50% ofyour compressed air system operating costs.
Convenient Top Exhaust
The cooling air flow discharges from the top of thepackage facilitating easy ducting for removaland/or recovery of exhaust heat.
Air-cooled or Water-cooled PackagesTo fit the needs of the compressed air systemIngersoll Rand offers the choice of an air-cooled orwater-cooled design.
Easy Serviceability
Our total package is remarkably uncluttered,
making servicing easy. All components are readilyaccessible behind easily removable panels.
Star-delta Starter
This advanced starter gives the compressor a
controlled, cushioned start, eliminating current
surges and extending component life for increasedsystem reliability

Up to 46C (115F) Operating Ambient
Our rotary screw compressors operate in highambient conditions, making them suitable forlocations around the world. Even if the compressoris not operated in sweltering climates, the hightemperature rating ensures fewer nuisanceshutdowns caused by fouled coolers.
End-to-end CoolingThe aftercooler is located at the inlet end of thepackage.
This allows cool compressed air as low as8C(46F) above the ambient temperature to passdownstream to the air system.
Rugged Motor
The extra toughness built into our electric motormeans it will run when other motors do not.
Maintenance and repair of the motor are just like
any other electric motor.
Easy Connectivity
The compressor is fully piped and wired, resulting insimple external connection of all utilities.
Quiet Enclosure
A low sound enclosure is standard and keeps soundlevels to a minimum.
Factory Tested
Every rotary screw compressor undergoes state-of-
the-art testing to ensure that you get the best
possible performance under varying conditions.
