Oil Free Compressors
Today, Ingersoll-Rand is the only manufacturer that can supply
you with oil-free compressed air on all three technologies: rotary
screw, reciprocating and centrifugal. And since each technology
has its benefits, Motherwell Bridge Air Systems can help you select
the one that works best for your application.
To fit the needs of your compressed air system, we offer you the
choice of a water-cooled or air-cooled SIERRA design.
Maximum Compressor Performance
With UltraCoat rotor protection and the extensive use of
corrosion-resistant materials, the two-stage airend gives you near-100%
capacity for its life. You also get ultimate energy efficiency that
will start saving you money on the first day.
Rotary Screw Airend
When you buy any SIERRA compressor, you get only superior, state-of-the-art
rotary screw technology. No substitutions.
Non-Corrosive Materials
Critical components are built from non-corrosive materials to
preserve the performance of the airend and protect the quality of
your compressed air.
46°C Ambient
SIERRA compressors are designed to operate in high-ambient conditions,
making them suitable for locations all over the world.
Easy Serviceability
The SIERRA package is remarkably uncluttered, making servicing
easy. All components requiring routine maintenance are readily accessible
behind easily removable panels.
Patented Moisture Separator Design
Designed to eliminate a problem before it starts, our patented
moisture separator, with its unique vortex design, removes condensate
before it enters the second stage of compression.
Rugged Motor Design
Every SIERRA compressor incorporates a durable high efficiency
motor – either an IEC motor for 50 Hz applications. All SIERRA compressors
operate well below the maximum service factor of our motors, ensuring
reliability.
Star-Delta Starter
This advanced starter gives the compressor a controlled, cushioned
start, eliminating current surges and extending component life for
increased system reliability
Quiet Operation
The combination of an inlet sound box and a low sound enclosure
design keeps sound levels at a minimum. What’s more, SIERRA compressors
have efficient pulsation dampeners on each stage of compression,
reducing noise even further while ensuring a pulsation-free discharge
for smooth air flow. Water-cooled: 76 dB(a) Max. Air-cooled: 79
dB(A) Max.
Factory Tested
Every SIERRA compressor undergoes state-of-the-art computerised
testing to ensure that you get the best possible performance under
varying conditions.
