Definitely oil filled compressor for my shop, thanks for the comparison. They are heavier and more expensive but the amount of noise already makes the choice for a couple hundred extra bucks
Thanks for the video. The noise level is a big difference. Also, I worked in a warehouse one time with a huge air that must have been 25 years old at the time compressor and it a a huge pump and tank. It only kicked on about once a day with very little use, I allays think about the sound it made. Just a soft deep thump a thumpa thumpa thumpa... they just do not make them like that any more.
Good choice, belt driven is the way to go. if any of the parts fail, they are easy enough to source and replace. If an oil less fails, you need to track down the stock parts. Smart move!
You are absolutely right about how noisy oil free compressors are! I have a small oil filled compressor powered by a 1.5 horse direct drive induction motor and it is also way quieter than a similar oil less compressor. Direct vs belt drive do not make it louder or quieter. It is the oil that makes the difference.
I'm a hardwood floor mechanic I go through tens of thousands of nails a and oil-filled or way better and last longer if you want something for the long term that won't break we've used regular oil-free and they only last a few months maybe a year if you're lucky so if you want something for around the house go for the cheap one if you need one for work go with the oil filled
We have always had a oil-less compressor and our last one died so we went with a 30 gallon Husky oil compressor and it is so much quieter and it fills up about 40 percent faster too. I will never go back to an oil-less compressor. We run 4 air guns at one time on it and it only kicks on a few times an hour which is phenomenal. I am sure if we were doing a roof it may run a bit more but for inside framing and blocking, it has done great. In fact, we used to put our old compressor outside and run the lines in a window to the work site. With our oil-less, we stashed it in the laundry room in the center of the house and we don't even notice it running throughout the day.
Oiless compressors are noisier and they dont last as long as oil filled compressors, but they are much lighter and this definitely a big plus when it comes to compressors that are on wheels and are meant to be moved around such as the ones in the video. Oiless compressors also do not require any maintenance and they arent so damn cumbersome. Plane and simple. Compressors are loud. I dont have any experience with the new quiet compressors they are making like the California brand compressors, but for the most part air compressors are loud and the tools that you hook up to them are loud. So to me it kind of defeats the purpose of opting for a compressor because its quieter when running when the tools you hook up to it are just as loud. I guess it really depends on the person buying the compressor. If you are like me and always forget to change the oil in the compressor then an oiless is the way to go. I had a oiled compressor for years and never thought about changing the oil in it untill it finally gave up on me one day lol. I dont know I guess once the compressor is up and running I dont think about it much other than hooking up a hose and tools. I do recommend if you do purchase and oiless compressor, to purchase an extended warranty with it that kicks in after the manufacturers warranty expires.
My oil filled 8 gal. is just as loud as the Husky you have there. The 8 that I have is also a harbor freight. size does make a difference with the sound thats for sure. Be sure to check that oil level every time... My wife froze the one she had at work up because she forgot to check the oil. Blew the cap on it. But... its working again :)
i have a oil filled direct drive (no belt and pulleys) hf compressor and its LOUD. even those hf belt drive ones are loud compared to slighly more expensive name brand belt drive compressors
+7808y You can get a 2.5 hp 21 gal oil Comp from H.F. for just under $160 with the coupon they send me almost every month. How much is the name brand belt drive compressor that u would suggest. Ive been thinking about buying one but I like to be informed and would appreciate any advise. I dont really care about noise but if u know a better compressor for a bit more I would love to consider it.
This is the 29 Gallon one right, I am looking into getting one, I am actually from Canada and am gonna buy it in the states because of the good price, is their anything I should be worried about with this one since warranty maybe an issue, how is it running for you and also has their been any problems
Why is there a choice between the two? Is there a risk of contaminating air with undesirable oil in the oiled filled type compressor opposed to the oiless type?
Maybe it is an artifact of the video but I didn't hear a significant difference between the two. Based upon the comments I thought my hearing was off and I set a sound meter on to measure decibels from the two air compressors. It read 60dB for oil-free and 59 dB for oil-filled. I am trying to determine if it makes sense to switch to an oil-filled compressor and based upon what I heard, there doesn't appear to be a significant decrease in sound.
Ditto on noise, but one use for mine is blowing out the fresh water system as part of winterizing my RV. I've heard the oil compressors put oil in the air stream and that would not be good!
I have had two oil free and both had problems that I had to repair and not long after I owned them, maybe a year . Just got the oil filled so will see how long it holds up however it definitely is quieter .
+chris10077 My old oil filed compressor ran and ran and never died.... had to leave it when I moved and looking at new compressors I appreciate it a lot more... paid 20 bucks for it after mice ate the wiring, easy fix. Best deal is a used ugly old one that didn't get much use.
Functionally operates just as it should ru-vid.comUgkxiiMg_x4gIWeXMWfBnDdRnME4qJUAva4w holds pressure perfectly when not in use. Glad one of the other reviews pointed out that the bottom pressure release valve was open; thought it was defective at first.
I think you find it is not the oil that causes the difference it is the belt driven Vs direct drive that is responsible. Belt drive compressors are much quieter simply because the motor can run slower and achieve the same outcome because of the multiplication of the motor's spin rate combined with the ratio increase of the large pulley on the compressor end.
If you take a closer look at the HF belt drive compressor you will notice that the pulley on the motor is much smaller than the pulley on the pump. So the motor is actually turning much faster with the belt drive compressor. In any event, try running an engine with no oil and another engine with oil, you will notice the one with oil runs much quieter and smoother. It is for this reason all professional 100% duty cycle compressors use oil filled pumps. Oil free compressors are for the weekend mechanics and light duty use only. Oil free compressors are super loud and they do not last long. It is not the belt but the oil that makes the difference.
Sharpeyed Watcher The oil makes absolutely no difference to noise levels at all. It's the motor which makes the difference. Oil free compressors almost all use a universal brushed motor, as you probably know from running circular saws, planers, routers and so on are quite noisy. These motors run at much higher rpm than the induction motors used on all oil lubricated compressors, direct and belt driven. In universal motors you get noise from the friction of the brushes and the commutator along with other electronic noise, you also have the noise of the pump spinning at the high speeds on the oil free compressor. In an AC induction motor there are no brushes, nothing rubs agains the rotor, it just is supported by bearings. However a belt drive induction motor compressor is quieter than a direct driven induction compressor because the pump is running at a lower rpm to to the motor due to the belt and pulley's, belt drive compressors tend to last a lot longer than the cheap direct drive compressors too.
Are you stupidm the motor turns thee same speed it's actually geared down to make more torque to spin thee compressor. An electric motor is very quiet has nothing to do with how loud the compressor is.
wes spinner wes spinner Clearly not stupid like you buddy, universal electric motors are noisy full stop due to the brushes rubbing on the armature which I have already stated, so your wrong about all electric motors being quiet. Direct drive compressors driven by quiet induction motors are noisy due to the pump spinning the same speed as the motor, belt drive compressors are quieter due to the pump running at a much slower speed than the motor. Think about it a direct drive compressor which has say a motor running at 1750rpm has the pump running also at 1750rpm so of course it's going to be loud with the piston and connecting rod going that fast, is a mower engine running at that speed quiet, no. By the way I think I know what I'm talking about too, being a carpenter and owning a big slow revving belt drive compressor and also using cheap direct drive (oil and oil free) compressors all the time. I've also taken apart the cheap oil less compressors you get at the hardware store like this one in the video and let me tell you there are no gears in those cheap and nasty things, rotary screw compressors have gears but not generally the cheap reciprocating ones from what I've seen. I believe you've mistakes rotary screw compressors for reciprocating compressors. So instead of thinking how smart you are I suggest you learn how they all work and the when you know maybe you can start big noting yourself and correcting people.
Even quieter is a lower RPM piston compressor. I replaced a cambell hausfeld two hp single stage compressor with a vintage Atlas Copco saved from the scrap yard and it runs at 1/2 the RPM and gives a lower puffing sound. I moved the compressor out of the garage to a ventilated and insulated compressor shack outside and the garage and shops are totally quiet now.
Some compressors are direct driven that are oil filled but turns fast to make cfm... I find the low rpm, belt driven compressors more pleasant to the ear I had one that was given to me as a kid that I belive is from the 50's a little one lung, and I just put non detergent oil and new belt and she keeps huffing along I would like to know who made it since it has no markings. But very good compressor
I got that same red husky 20 gallon ... YES it is FREAKIN LOUD ... And that new one is almost half as loud ... And technically is not "filled" with oil ... its not like they made an oil free engine then filled it with oil, its a normal oil lubricated engine vs the other designed to work without oil. Its like an air cooled engine vs water cooled engine ...
There are no engines on an air compressor. There is an electric motor, and there is an air pump which either has an oil filled crankcase or a direct drive connection to the motor, eliminating the need for oil lubrication.
...and I quote: " its not like they made an oil free engine then filled it with oil, its a normal oil lubricated engine vs the other designed to work without oil. " (Similar to using ITS when you really meant IT'S.)
@@gregs.7963 you can quote what i wrote ALL DAY LONG ... the fact is i never said there was an engine in there. Maybe go back to class and ask the teacher ?? Maybe he/she can translate it for you ??!!??
Thanks for the video I had a oil filled and then got a oil less. and it drives me nuts. it seems to run forever and loud as heck.Do you notice if it fills faster too with the oil filled?
It's a lot more to do with the reduction in NVH due to the oil and the fact the piston is fully enclosed. It's also something to do with having an induction motor instead of a universal motor.
Quietness of the oil-filled compressor in this video is caused by another design -- belted vs. direct drive. Belted compressors are more quiet than ones with direct drive, as my experience shown.
YOU GUYS! PAY ATTENTION! He said the red Husky was OIL-FILLED. He made the correction AFTER the pump stopped. The Central Pneumatic is the oil-LESS comp.
You're comparing 2 completely different styles of compressors, which is more than your claim one is oiled & the other one isn't. The fact one is belt driven adds to the equation.
Exactly. The same type of compressor that uses oil is very nearly as loud as the oil-free one. Belt-driven compressors are much quieter. But you also get oil-free models that are very quiet these days.
Unfair comparison.The oil free runs at a higher RPM and has smaller piston. Check out California air tools. Oil free compressors RPM 1680 WITH BIGGER PISTON AND QUIET.
