When you buy MMD Equipment, you get much more.The cornerstone of a great buying experience is a high-quality product. But to maximize your productiv-
ity and income, you need more than just a machine. That’s why MMD Equipment is committed to adding
value in every aspect of our business relationship. With every MMD Equipment product you purchase we
stand behind our PROVEN PERFORMANCE, SERVICE and EXPERIENCE.
Super-quiet. Super-efficient. And super-profitable.When it comes to efficiency and dependability, MMD Equipment’s ultra-quiet air
compressors are designed for today’s demands. They’re extremely
reliable — which helps reduce downtime and maintenance as well as increasing
your profitability. Just as important, our superior designs meet environmental con-
cerns and are fuel-efficient, light and well-balanced.
AIR COMPRESSORS
Easier, Faster Service and Maintenance• Engine oil and water drain to the outside
of the machine.
• Hand-operated compressor oil and fuel
drains (no tools required).
• New external oil/air separator filter and
cartridge-type fuel filter reduce service
time and cost.
• All service areas are located on one side
for easy maintenance.

Interim Tier 4 and CARBCompliant• The AIRMAN PDS185S uses an engine that
achieves emission reduction targets that
comply with the EPA’s rules governing the
Federal Clean Air Act and CARB’s regulations.
The PDS185S Delivers Maximum Air Pressure & Fuel Efficiency.
Quiet, High-Efficiency Design• Engine idles as low as 1,300 RPM — with an auto
idle feature — to provide the best fuel economy
and reduce component wear.
• Noise level is as low as 62 dBA at 23 feet when
idling. This is substantially less noise than
competitors’ machines.
• Direct-injection engine meets strict new EPA
Interim Tier 4 emission standards on the
PDS185S.
Convenient Access and Storage• Gull-wing style doors allow easy one-hand operation!
Large, lockable doors with gas struts virtually lift
themselves for easy access to tool storage and service
components.
• Larger tool compartments hold 90-lb. breakers, various
tools and hoses.
Best Fuel Economy• The PDS185S offers the best fuel economy for any air
compressor in its class.
• An auto-idle feature saves fuel by reducing the engine
speed to 1,300 RPM when there isn’t a load on the
engine.
• Fuel economy is maximized by reducing resistance dur-
ing air intake and discharge.
• An auto-sensing ECO-MODE decreases receiver tank
pressure during unloading.
Durable, Reliable Construction• Powder-coated finish and stainless steel hardware
maintain their attractive appearance.
• Engine is directly coupled to the air end by a fiber gear
coupler for improved power transmission.
• Improved unloader valve and air pressure regulator
feature O-rings instead of diaphragms.

One-way valve automatically controlsair entry into the compressor based ondemand sensed by the pressure regulator.
Fiber gear coupler delivers quietoperation, is maintenance free, andallows easy removal of either theengine or air end. The coupling willnot deteriorate due to vibration,heat or length of service.
Oversized bearingscombine to give solidsupport during transferof power from the geartrain to the rotors.This ensures excellentreliability and extendedservice life.
Large-diameter air screws producemore air at lower RPMs, reducing wearand increasing fuel efficiency. Also,slower-turning screws mean less noiseand quieter operation. AIRMAN screwsfeature a patented SmoothSealTM rotoredge profile to eliminate blow-by andreduce internal friction.
The pressurized oiling systemcontinuously lubricates and coolsthe mechanical componentsincluding rotors, gears andbearings. AIRMAN’s All-seasonsTM
oil is specially formulated toprovide unmatched compressorreliability and service life.
Check valve eliminates back-flow and allows multiplecompressors to safely feed acommon pressure tank inhigh-volume installations.
Double oversizedbearings hold thepositions of thetwo rotors in aprecise relationship.Bearings arepressure lubricatedfor both cooling andlong service life.
Thick, reinforced castings deliverincreased strength, increaseddimensional stability in sealingareas, and better support to thebearings and rotors. AIRMAN’sheavier castings evenly transferheat away from the bearingsand rotors to reduce internalthermal stresses.
AIRMAN Screw Air Compressors —The Ultimate in Reliability.
Day-in / Day-out power train dependability.The reliability of the AIRMAN air compressors are proven in thousands of applications worldwide and
backed by a standard 5 year or 5,000 hour engine warranty on the PDS185S and a 2 year or 2,000
hour warranty on other models. A standard 2 year air-end and coupler warranty is extendable to 5
years with the use of AIRMAN oil and filters. In addition, you’ll be supported by MMD Equipment - your
partner in success. (see complete warranty for details)

• 5 year, 5,000 hour standard Nissan warranty.
• EPA Interim Tier 4 + CARB compliance.
• Advanced design virtually eliminates diesel chatter.
• An enlarged fuel filter enhances diesel fuel cleaning
and performance.
• Side-by-side radiator and oil cooler provide reliable
performance and easy cleaning.
• Improved output engine on the PDS185S provides
185cfm @ 100psi with a 13% reduction of crank shaft
speed.
• Quiet direct-injected engine reduces noise by 20%.
• Compare our fuel economy vs. other models and you will
buy an AIRMAN.
