Central Pneumatic 6 Gallon Professional Oilless Air Compressor Review

Oilless Air Compressor

This is the Harbor Freight central pneumatic brand six gallon professional

oilless air compressor like I said it’s six gallons it has 150 max working psi

and it’s 1.5 running horsepower and has a low maintenance oilless design and the

air delivery is 2.5 s CFM at 90 psi and 3.4 SCFM at 40 psi it includes a quarter

inch Quick Connect coupler here’s what the unit looks like right here you can

see the coupler right over here regulator two gauges for your tank

pressure outlet pressure Aasma safety valve on/off switch of course and that’s

pretty much it this is item number 62, 380 still has the oils pump which is low

maintenance with an exclamation mark particular one was received by Harbor

Freight January 20th of 2016 now before we go ahead and open the box up a few

things that we need to get out of the way first of all let’s talk about

oilless versus and oil lubricated compressor an oilless compressor has no

oil in it but inside of the compressor is a piston that moves back and forth or

up and down depending how it’s designed and just like your car it needs oil to

keep everything lubricated the way that’s done on an oil is air compressor

is through the use of a sintered sleeve so in other words the cylinder bore

where the actual piston goes up and down is lined with a sintered material what

that is is basically a whole bunch of little metal shavings that are

compressed together under very high pressure with oil basically impregnated

in that so it is lifetime lubricated but of course that lifetime is whatever the

lifetime of the actual compressor is certainly not your lifetime an oilless

compressor will not last as long as an oil lubricated compressor so before you

buy you may wish to consider that if you want to hold on to this for a very very long time

and not have to buy another one anytime soon and we’ll get into that in a moment

then you may wish to pick an oil lubricated compressor instead oil

lubricated compressors are going to be physically larger you won’t find them in

a small pancake design like that as you see they’re going to be larger typically

we’ll have wheels on them so you can wheel them around from place to place

they’ll also be heavier for regular viewers of my channel who are aware that

I have the 3 gallon version of this this is basically the Big Brother to it this

is actually not for me this is for somebody else but I’m just doing a

review of it before I pass it off to them so that’s why it’s here

now again before you buy if you think the diminutive size of the unit is going

to mean it’s quiet you’re sadly mistaken it is 90 decibels running that’s pretty

loud that’s over shouting level when you’re yelling at another person ok so

it’s going to be very loud small compressors and especially oilless

compressors are very loud by design what is this good for it says on the box it’s

perfect for inflating you can use a blow gun or air brushing although there are

separate compressors available for that that would probably do a better job and

it’s also good for light woodworking for Brad nailing and stapling it says for

intermittent use you can do heavy mailings such as a framing finish and

roofing nailer that’s a really big one instead of just your typical brad nailer

so that means that under intermittent use you can get away with that but

intermittent again means it’s going to use up a considerable amount of air and

you will have to wait for the tank to recharge how long that’s going to take

is something we’re going to find out a little bit later on in this explanation

it says not recommended as hobby paint spraying automotive repairing such as an

impact wrench or ratchet metalworking for a die grinder or hammer and heavy

auto restoring for Sanders spray gun sandblast or cut-off tools

can also be used to fill tires up on your car you will need a separate piece

for that that would fit your tire so all in all this is great for light duty use

and probably very infrequent use which would give you the best lifetime now

again I said I was going to get into how long this will last well that really is

going to depend on how much you use it and especially how much you abuse it how

long will this last well unfortunately I’m not a fortune-teller

I’m a youtuber what I can say from experience is the three gallon one that

I have lasted a year and I beat the ever-loving crap out of the thing so you

probably would get a lot more usage out of something like this especially if you

use it a lot less frequently for example if you’re going to use it for a weekend

maybe once a month I’d expect you to get a couple of years out of it again

an oil lubricated compressor is going to last considerably longer the oil

lubricated compressor that I have in my crotch which of course is much larger

and has a much bigger tank on it I’ve had four three maybe even four years now

and that’s used well rather infrequently there’s some months it’s not even used

at all especially during the winter mentioned earlier in the explanation that this

is going to another person and this particular compressor is going to be

used rather heavily for about two days out of the year I’m using this

compressor for a purpose that is something else that is actually rather

important that you should keep in mind an oilless compressor generally won’t

care about the the the weather and that means that if you’re in a colder climate

typically this will start up and run without any problem an oil lubricated

compressor just like your car gets sluggish to start in the winter that oil

becomes thick and it may have a hard time starting for the work that this is

going to be doing I had done once with an oil lubricated compressor and I

actually had to heat it for several minutes with a hairdryer to get it warm enough

that it would actually start once it started it was fine but like I said an

oil-less compressor as such probably won’t have that trouble this will be

stored in a colder climate and it’s going to be used basically in the fall

to blow out an in-ground sprinkler system I do not recommend this

particular compressor for that I would highly recommend you get at least a 10

gallon compressor to do that but of course that is going to depend on the

size of the sprinkler system my particular one I have in the garage is

22 gallons and that’s more than plenty for that this again will be used in a

much smaller sprinkler system to blow it out and that a little later on in the

year probably November or December it’s going to be used to blow out the

plumbing in a vacation house so there’s not really that much piping in that and

I expect that this will do a fine job of that so that’s why I chose this

particular one for the person that is going to be owning this anyways without

any further ado let’s take this out of the box and see what it can do here is

the unit in its flesh and we’re about ready to get started here however before

you do that you need to do a break-in procedure on it that is to simply run

the unit with no load on it and the drain valve on it open for 10 minutes

according to the instructions I’m going to be nice and give it 15 minutes so to

do that you want to first make sure the regulator is turned all the way up so

you turn it clockwise like that you can see on here if the Sun will cooperate a

plus and minus sign on there and it says in that direction for plus so we will

turn it all the way up like that here’s our quick disconnect fitting right here

and you two gauges for tank pressure and outlet pressure on the back here is the

drain valve it’s currently closed you can see the plastic piece here that you

turn is perpendicular to the direction of the outlet so turning it parallel to

that opens the valve so you want to open that up and now

we’re going to plug it in and turn it on and let it run we’re all set to go I did

test the power switch before plugging it in which also by the way has this little

vinyl covering over it to protect it and it feels like it’s a nice quality switch

I don’t know what that speaks about the rest of the unit but we’re going to find

out now here we go and now we’re going to let this run minutes or in this case I’m going

as a break-in period over here I do feel. OK we’ve successfully completed the

break-in and I close the drain valve like that the wad meter hooked up this

particular unit as per the Box States nine point seven amps at 120 160 four

watts we’ll see how close it is to that we’re also going to see how much time it

takes for the compressor to start up I will start out on the watt meter over here

and there we are it says it goes up to 150 it’s well just about 150 that’s

close enough right there and obviously we show no more wattage there it’s

reading zero it read just what it was supposed to so it looks like everything

worked next step is to test the ASME safety valve so just pull on the ring

here it’s going to pop blast air out and then it should eventually reseal itself and pump back up

okay you can see I have an air hose connected now along with just the

standard blowgun here the cut in pressure is approximately 120 psi I’m

just going to blast it and let it keep going you will see when it hits around

the 120 mark it will fire back up and try to refill but again I’m going to

keep on blasting just giving an idea how much air you can get out of this before

you get down to an area that is not producing enough airflow for you

so it seems that using a blowgun with it looks like it will produce an adequate

amount of airflow for quite some time so a six gallon air compressor will give

you a considerable amount of airflow before you really have to stop and wait

for the tank to recharge so my first impressions of this pretty good I can’t

really complain I could see how this could serve you for some time to come

provide it is treated in a respectable manner and not abused looks good all

around seems to work very well I think it’s thumbs up for me now before

you’re done with your compressor you want to shut it down and empty the tank

and to do that turn the switch off you can of course unplug it which I will do

a little bit later and you want to open the drain valve let all the pressure out and also chip

it backwards a bit don’t break off the plastic thing there when you do that

because you see it’s touching there and that will help the moisture come out you

can see there’s actually a little blob of ice that is formed there which is

completely normal always drain your air tank when you’re

done using it again this was the Harbor Freight central pneumatic brand six

gallon professional oilless air compressor item 62, 380 looks good

oftentimes Harbor Freight will have this on sale periodically throughout the year

it’s normally 1:29 and oftentimes they’ll have it on sale for $99.
