Tom, I have to agree with you on the older I-R's. These were quite the machines in thier day. The new ones are not anything like the old ones and I-R is following the path of Cat. You buy our stuff, you pay our prices. Parts for many of the older machines are no longer available and if you are luck enough to get parts, they come at a very high price. I had a deal early last year where I tried to get valves for a 1972 model year. They did have them but the price for the 6 valves was around $1050.00 three times what the compressor was worth. Subsequently, this unit was replaced with a Champion of the same size purchased for $1400.00 The biggest thing that turned me off completely with I-R is there lack or factory quality control and failure to respond to problems with their equipment. Reports I have gotten back from other people who deal with compressors on a regular basis also verify that the newer I-R's are crap and should be avoided completely. I don't mind bragging on products that are good and worth the investmet and I also will not hold back on telling people about products and companies that are not worth squat. I-R falls into the "not worth squat" catagory in my book. Brands I will endorse: Light duty only - Campbell Hausfeld, Emglo, Black Max, Puma & Coleman Heavy Duty - Quincy, Champion, Saylor-Beal & SpeedAir. My suggestion for anyone looking to buy a new compressor (except for those only airing a tire 3 times a year) for running air tools and such but not on a heavy duty basis, look at the major heavy duty brands first. These companies build thier smaller machines to the same quality standards as their extreme duty machines. From what I have seen, most of the prices are very reasonable too. When you compare buying a machine that sells for $550 (average price for a decent sized light duty) and buying a high quality medium duty machine for $750 that extra $200 spent on the better machine will save you the $550 you wasted on a light duty one. Light duty is just that, light duty. Low use times, slow recovery, and a very limited life span. Generally a light duty being used part time and weekends could be expected to last around 1 to 5 years before starting it's fatal degredation phase of it's life. A medium duty machine built by a reputable company running in the same manner as the light duty will last around 10 to 20 years before starting to degrade. (assuming normal maintenance is done properly on all machines) The real benefit lies with performance. The medium duty machines will take a lot more abuse than will a light duty. Say you have a bigger job you take on like sanding a whole car. Air sanders eat up a lot of air and the compressor is going to run much harder than with things like and ratchets or impacts. These long running times create heat breakdown in the smaller light duty compressors. This is why a light duty built with an aluminum head and cast iron cylinder liners is much better than a full aluminum head or a full cast iron head. The AL allows the heat to disapate faster than a full iron head. The full AL heads die rather quickly and should be avoided for any uses. Depending on the design, meduim duty's will have either a full cast iron or a cast iron lined AL head. Either is fine and is dependent upon the ratings of the machine including as to if it is pressure lubed or spash lubed. Everything comes together in the design and rating phase to ensure the unit is constructed for the maximum use value. I have an engine drive Champion that is an iron lined AL head. This unit puts out 17 cfm @ 175 psi and sometimes runs for 12 to 15 hours at a time at 80% loading. 6 years since I purchased this unit and not hint of degredation however, it does get serviced at the recommended intervals. In my view, it is better to spend a little more at the start than to spend a lot later. In my experience, the main killers of air compressors of any kind is lack of proper service. You change the oil and filters in your car every 3000 miles so why should you not expect to change the oil and filters in your compressor every 75 hours? Blowing out the air filter elements is not good practice. REPLACE them. This is when you must ask yourself what is better, buying good oil for $3 per qt and a new air filter for $6 or throwing away a dead compressor for $600 or more?
