*2.5 HP 4 Gallon Oil-Lube Air* Compressor \| Porter-Cable CPLDC2540S**
	$580.00 by Porter-Cable Three year limited warranty Full roll cage with high flow regulator and dual quick-connects Patent pending oil-lube system with ball bearing design Direct drive, no belts or adjustments are necessary 2.5 HP, 4.3-gallon oil-lube compressor found in CPLDC2540S's description: From the Manufacturer Porter-Cable is proud to introduce our first oil-lube compressor. When we first put our engineers on the task of designing an oil-lube compressor we gave them one priority; it could not have the same imported pump as all the other major brands have. Just as in a car, the lubrication system in the pump is the most vital part in a compressor. The design features don't stop there; it boasts a cast-iron cylinder, stainless steel Swedish valves, and an automotive type paper filter to trap unwanted particles before they enter the system. Now, take this revolutionary pump engineered for maximum durability and life, and add in the "High Pressure Technology" and you have compressor that will run at 150 pounds per square inch (PSI).5 horsepower induction motor is safely shrouded and acts as a wind tunnel providing more than enough air to cool the unit down even under the most strenuous conditions. oil capacity to assure long life Patented oil lubrication system allows pump to be operated on an uneven surface Protected panel includes two universal High-FloSM push-to-connect couplers and larger, easy to read regulated air pressure gauge 150 PSI tank pressure, equivalent to a 7.3 gallon tank at 125 PSI, for 71% more stored work capacity 83 Dba Higher 120 PSI cut-in pressure assures nails will be completely driven in before pump cycles on Two pole, 3,450 RPM capacitor start induction motor for maximum air delivery High-FloSM air regulator for more work at higher pressure (125 PSI start and 150 PSI stop pressure switch) Specially designed protective transport handles Low 12 Amp motor draw prevents accidental tripping of circuit breakers 4 gallon storage capacity air tank supports heavy usage of stapler, brad, finish, roofing and framing nailer Standard Equipment: Compressor, ASME safety valve, air regulator and gauge, 1/4" quick coupler, oil, and operating manual SPECIFICATIONS Lubrication: Oil Lube Gauges: 2 Quick Couple: 1/4" NPT Weight (Lbs. PSI: 150 SCFM Air Delivery @40 PSI: 5.4 SCFM Air Delivery @90 PSI: 4. found in CPLDC2540S's reviews: *A- compressor* except for the regulator - I've been searching for a portable compressor for a couple of months now and near the end came up with three to chose from: the Emglo 55155, a Hitachi dual stack and this PC. Other compressors did meet these, but what draw me was the oil lube system that permits you to use it on uneven surfaces. This should be the norm! Other good things are excellent build (USA), non-ball type draincock (ice can ruin a brass ball), pressure release valve (to lower the pressure before you open draincock that can shoot projectiles), caged, not too bad noise level about 83 dbA (noisy street), lower running 1.5max) to not trip the circuit breakers, filtered intake (not output though) for longer motor life, shrouded motor for airflow from fan and good manual. Mine leaked just like the last reviewer had, so I opened it from the front and saw that the valves inside weren't centered to each other. The only thing I added at the universal coupler end is a water/air** filter.

Built-in Storage Compartment - Conveniently stores air fittings & accessories. Air Hose Wrap - Stores 50 of 3/8" Air Hose with handle folded or upright. Large automotive style industrial air filter for increased air intake and greater efficiency. found in MAC5200's reviews: Worried, distressed, & troubled - Not - turned out awesome!!! - Now to the unit - awesome!!! A container of compressor oil was included - filled the oil reserve and went to "initial startup procedure" on page 10 of owner's manual. Was somewhat confused by Step 1 - open the "air receiver's drain value". What the %^& is a air* receiver's drain value??? I know what the Drain Valve or Cock at the bottom of the tank is - but was I missing something? A fast call to Makita's service center confirmed to open drain valve on tank for the no-load break in. I think I'll be very pleased with this compressor if everything remains as positive as the initial impressions. Good specs for the price range - 8 amp draw, collapsible cart, oil lubed pump, good air filter and ball valve drain. Did not find many other compressors in this price range with those specs and did not want to pay $600+ for a monster. The manual says it has a 50% duty cycle so if you need a compressor that will run without stopping look elsewhere. On arrival the box had major rips and crushed areas fairly typical of my experiences of UPS shipment with heavy items.

This is what I was looking for in a compressor.and this is why I specifically went looking for Thomas Compressors.Since then I have been waiting for my Emglo to get retired so I too can be a proud owner of a Thomas T-635HD One thing that I did not like when my Thomas T-635HD arrived was a real lack of directions to assemble the few parts that did need to be put on before operation, but anyone with common knowlege of compressors will figure it out. REMEMBER!!! to get a pressure control valve, and all the connections you will need to mount a hose coupler; because these items do not come with the tool. This compressor is not intended for HIGH-PRODUCTION ie. if you are in the market for a compressor that is small,light;and dependabley quiet. Your search has ended here ! Don't get fooled by tool packs that come with nail gun, air-hose and compressor in one deal you will be looking for a new compressor soon.

Which brings me to my first complaint: during that job, a couple of the fittings under the protective plastic shield vibrated loose and leaked enough air that the compressor couldn't reach shut-off pressure. Using the nailer at 100psi, the compressor cycled fairly regularly, but could keep up with the nailer without any trouble. Noisy? Yes, but so is every other air compressor I've ever heard, and it cycles fast enough that for occasional use it's tolerable. My only real problem with the HL5501, other than fittings that come loose, is that the air outlet comes off the side of the manifold in such a way that by the time you've attached a water filter and a female quick-disconnect fitting, there's quite a bit of potential leverage hanging out there unprotected. I'm always worried about hitting it, or pulling the air hose too hard, or doing some such thing that bends the manifold, or tweaks the regulator, or busts the water filter. Oh, and in freezing temperatures, the pressure release valve tends to stick open. Make sure to site it so that that air outlet is protected.

More delivered air (CFM) gives you the power to do the job right and in less time. found in SS3L3's reviews: Perfect - I have owned this air compressor for about two years now and it was worth every penny. The compressor is excellent, So far I have run my compressor about 100 hours thus far. It has always supplied my with an ample amount of air when using air tools except if I run my impact for 10 minuets continuously then it drops to 70 psi. I would recommend this compressor to any one with out hesitation. I turned it on two years ago and it has been on ever sense it kicks on about every hour because there is a leak I have not fixed in my air system. Yes it puts of a lot of heat but if you do the math PV=nRt you will see that a lot of heat is given off compressing that much air. Finally the issue with the valves being cheap. Why do you need to make it more complicated if it works reliably with such a simple valve. Also in response to the allegations that the tank was going to over pressurize If the switch failed and it continued to run there is a spring loaded safety valve on the power switch on the compressor so it is not possible to over pressurize it, mine hits about 133 before it kicks off. A cheap way to get more CFM... but its still cheap. - This air compressor is identical to my Ingersoll Rand SS3L3 compressor that I purchased through Northern Tool in the early summer of 2005. This is the first air compressor that I have ever owned, so it was a learning experience from the start. It is recommended that you purchase the IR SS3L3 startup kit as the compressor is delivered to you without any oil in it. When I plugged in the compressor to test it out, I found that the motor continued to run even as the gauge on the tank passed 130 psi. I ran the compressor off and on for several months without any major issues. a little bit of die grinding, I rotated the tires on my car using the impact wrench and air ratchet, I used it to blow dust off my work bench and check the air in my tires on a routine basis. I bought the compressor because I have several project cars, and I would like to begin the serious work of restoring them. Recently, I have been looking at plans for a sandblasting cabinet, and I am starting to doubt that this compressor will stand up to the task of sand blasting for extended periods. Things I have learned about the compressor since its purchase that have led me to this conclusion: 1. (I swap between my compressor and my dryer on the only 230V outlet in my house). This borderline false advertising is similar to peak and RMS power ratings in audio amplifiers, though it is fairly standard operating procedure to rate motors in this fashion. Though it is quieter than a direct drive unit like the 30 gallon compressors sold at most hardware stores, 3450 RPM is still quite fast. With the pulley ratios, the compressor crank spins at 1200 RPM. Heavier duty systems might have the AC motor running at 1200-1750 RPM with the compressor running at ~700 RPM or less, resulting in a much quieter setup. There is apparently no available rebuild kit for the compressor itself, according to the local IR dealer, though they do sell gaskets and the oiling kit. It is a two cylinder, single stage compressor. The "valves" in the head are what I believe are called "reed valves", which are simply spring loaded "fingers" that cover holes in the cylinder head, and they move with the blowing/sucking of air as the pistons move in the cylinders (no mechanical actuation of the valves). The compressor can run fairly hot, especially when pressurizing the tank from zero pressure. I would like to add an intercooler in line to the tank as the compressed air is quite hot, and I think the compressor itself could use some more cooling. I bought some copper to fab up a larger heat sink for the compressor housing, though I haven't made it yet. The flywheel on the compressor is designed to move air over the unit, but I still think the design needs improvement. There is a flimsy petcock drain valve in the bottom of the tank that is difficult to access. I would like to replace this drain valve, if possible, though I have been putting this off simply because I don't want to lay down on the floor and fiddle with it. (Note: Added 10/10/06 - I added a Swagelok right angle 1/4" male NPT to 1/4" tube adaptor to this drain orifice, then plumbed 1/4" tubing out from under the tank and connected this to a ball valve. This makes me want to install a condensor between the compressor and tank). Copper tubing is used to route compressed air from the compressor to the tank, and I think some improvements could be made there, as well. One could remove the compressor to change the oil, but a better soultion would be to insert a ball valve in the oil drain plug for easy draining. IR sells the SS5L5, which uses the same 60 gallon tank, but a 5 HP split phase 3450 RPM motor running a different two piston single stage compressor. My biggest complaints are the use of the split phase motor, the relatively cheap design of the compressor (aluminum rods and lack of rod bearings), the flimsy pressure switch, and the cheap fittings used all over the machine. I will continue to use this unit for some time, but I am already considering either building my own low RPM, true 4-5 HP air compressor from various parts suppliers, or just purchasing a new one from a company like Eaton Compressor. Like houses, I think good advice for someone looking to buy an air compressor is "buy the most you can afford". I for one like the idea of a compressor running at a quiet 750 RPM at a mere 73 dBa, as opposed to my high revving 1200 RPM SS3L3. (Note: Added 10/10/06 -- As far as safety is concerned, this item will never blow up and injure anyone - IR has installed safety valves all over this tank as the other reviewer mentioned. Meanwhile, my criticisms of this unit are based on what I'd like to see in a compressor, that is all.
