Pros: High Tank Pressure, Portable, Initial Purchase Price
Cons: Marginal Pressure Switch, Universal Brush Motor, Loud, Light Duty Piston, Drawn Cylinder
Best Uses: Home Use, Limited Lightweight Use
Describe Yourself: Professional
Bottom Line: Recommended with restrictions called out below
I borrowed a C2002 unit a few years ago when installing rosewood flooring and needed to run my nailer at ~120PSI. Recently I found a C2002 at a local HD during a compelling seasonal sale. I did a quick tear-down and found the following.
The tank pressure limit switch is an extremely inexpensive, nonadjustable unit supposedly rated for 15A switching. While the motor load is called out at 10A, in service the pressure switch contacts appear to weld shut and prematurely fail to open at 150PSI, causing the pressure relief valve vent avoiding disaster. You can find many end user documented cases of this problem. This may however be remedied by addition of a 20A 120VAC relay to switch the motor load and will eliminate premature failure of the pressure switch (part cost of the pressure switch is $25 ±, where the proactive relay modification will set you back about $5).
The compressor piston appears to be some sort of sintered lubrication impregnated alloy running in a drawn stainless steel cylinder. No idea what the expected life on this engineering feat may be but I'm not very optimistic. I'd pick up a replacement sintered piston ring and cylinder sleeve if PC would offer these at a reasonable price. Otherwise after the pressure switch modification above, these appear next in line to wear in service such that the pressure achieved (one of the few market differentials for this unit) and effective air volume displacement of the compressor will gradually decrease (repair part cost $25 ±).
The motor is an inexpensive universal, brushed type which contributes to the runtime racket. The brushes while reasonably substantial, are a presumed wear out component with a replacement pair setting you back a whopping $20 ± per set. Other expected wear items such as the compressor reed valve plate seems to be a reasonable design and is inexpensive to replace. Ball bearings and even the timing belt are available elsewhere as generic parts.
If PC could redesign this addressing the above caveats ideally as a oil-lubricated unit (may be tough to maintain the under 30LB weight) and at the $99 price point, they would have an uncontested winner for the portable-duty compressor market. However as-is I'd recommend this for light duty as a disposable unit or for modest use for the mechanically inclined comfortable with the above modifications and prospective repairs.
