Harbor Freight Tank Air Compressor Regulator and Tool Oil Fogger

Air Compressor Regulator

Hey there YouTube Matt back with more Harbor Freight goodness and this time

it’s Harbor Freight Rube Goldberg special if you were following my shed

build you may have figured out that the shed is pretty far away from the house

it’s so far in fact that running extension cords out there for something

heavy-duty like an air compressor it’s just not going to happen I would need at

least ten maybe eight gauge wire and 500 feet of it which is going to cost almost

as much as the shed so instead what I’m gonna do is I’m gonna leave the

compressor nice and happy here in the garage and I’m gonna run air hose all

the way out there five hundred feet of air hose is a tiny fraction of the cost

of the extension cords I would need and there’s really no there’s no harm in

running air hose that far for low volume tools if you were trying to run a sander

or something else that consumed a lot of air even painting would probably not


work unless you had some really really big around hose but in my case all I’m

running is pneumatic nailers and maybe a stapler so they require pressure but not

so much airflow so my 500 feet of hose is gonna be just fine but you know me I

can’t leave well enough alone with anything

I had this yellow tank sitting around it of course is a Harbor Freight special

central pneumatic it’s just a little five gallon compressed air tank I got

this and I used it to inflate tires when I wasn’t near the compressor and but

it’s been sitting around for a long time and I figured more tank is probably

always better when it comes to an air compressor Plus this is portable I could

put this at the project end of my 500 feet of hose rather than back here at

the compressor end so I would have a volume of air pressurized you know that

didn’t have to travel through 500 feet of hose to get to the tool I’m operating

so what I have cobbled together here is a pressure regulator

and a tool oiler and what this lets me do is charge the tank all the way up to

120 125 psi whatever whatever the compressor can muster basically it kicks

off at 125 it kicks back on at about 110 psi so the pressure in this tank will

vary between those numbers but I don’t really care how long it takes to push

the air through all the hose and into this tank because once it’s in the tank

it’s where I need to be this regulator then lets me set the pressure that I

actually want to deliver to the tool and it varies pretty wildly for for nailers

when I’ve got the stapler or this little brad nailer I only need 60 maybe psi to

drive those things in you know depending on the material of course but 60 70 psi

no problem the framing nailer into the pressure treated four by fours that form

the skids of the shed requires every bit of 90 95 psi so it’s gonna be real real

handy to have the regulator local right where I am rather than having to walk

all the way back to the compressor to make a pressure change and then walk all

the way back out to the project likewise the tool oiler is something that you

absolutely positively need if you expect any kind of longevity out of impact type

tools nailers anything like that it has a piston in it most air tools in fact

unless they are delivering air to the work surface require oil in the in the

air line however there are some that don’t for instance when you’re running just

the blower you don’t usually want to blow oil all over stuff air feed to a

plasma cutter doesn’t doesn’t want any oil in it and there are you know there

are some other things that that don’t really require oil so this arrangement

is gonna give me a quick and easy way to use the oiler when I need it and then

when I don’t I just disconnect the hose from my compressor I’m using the handle

for strain relief here I guess maybe I should have a 90-degree elbow or something there but

anyway point being I can have loyal when I need it if I don’t want to oil I just

don’t use this entire thing no big deal let me grab the camera I’ll give you a

close-up tour of how this whole thing is put together then we’ll drive a couple

of fasteners just because we can starting up here on the tank itself see

that we’ve got I don’t know if you can read this or not but there’s an on/off

valve on the tank that is handy because when you go to disconnect this whole

thing you’re going to end up with an open port where the main supply line

comes in and this valve lets you shut the tank off so that you don’t lose all

the pressure that’s in here just because you disconnected the supply line the

flexible hose coming out of here is labeled half inch diameter outside

quarter inch diameter inside don’t you believe it you tube it is more evidence

that the Chinese have not mastered the imperial units system who could blame

them imperial units make absolutely no sense I got out the calipers and

measured it and it comes out at about 310 foul which means if you buy a

quarter inch fitting for the end of this hose it’s gonna just fall right out no

matter how much you try to tighten down the hose clamp fortunately the Harbor Freight 3/8 inch

fittings are in fact under sized they should be 375 foul and they’re not

they’re more like 330 so a 3/8 fitting goes right in the end of here no problem

and I’ll show you that down on the other end you can see that the tanks got 110

105 I don’t know something like that psi in it I may not have the regulator on

the actual compressor cranked up all the way but if you if you give it everything

it’s got you can get this tank right up to the redline nice and full of air

coming down to the business end of this thing you can see how I’ve cobbled it

together this black hose coming in from the bottom is the original hose off of

the tank it was designed to inflate tires it had this on the end of it but a pair of

snips took care of that no problem this is where that 3/8 inch hose barbed

fitting is installed and the hose clamp that comes with it goes into a quarter

inch NPT tee fitting the top of the tee fitting is where I have the Quick

Connect for the air line coming from the compressor now again I don’t know if I

like this coming in the top the handle of the tank does work reasonably well

for strain relief but I don’t know something about this just makes me think

I should have a 90 here and have that hose come in from the side maybe someday

the regulator is simple enough you have to pull up on the knob to be able to

twist it right to increase the pressure or left to decrease the pressure

and there’s a second gauge here on the front that shows you what pressure will

be delivered to the tool in between the regulator and the tool oiler where

there’s no chance of you seeing it is a bracket and when I originally conceived

of this I had a quarter inch male to male adapter that I was going to put in

here with teflon tape between these two things and what I quickly realized is

that that was going to be a nightmare there was no way that these two things

were gonna end up flat and even and square to one another so that they would

mount nicely if I was trying to thread them both onto just an adapter so I was

all set to make a little piece of hose and mount these two things to the tank

separately when I discovered that Harbor Freight actually sells a bracket which

is specifically designed to attach these two things together and then give you a

sturdy bracket to mount them to to whatever you’re going to mount them to

so I dispensed immediately with my male to male adapter theory and bought the

bracket it’s only three or four bucks or something like that comes with a rings

that seat between these two things and when you tighten down the screw these


clamps are beveled so it actually pushes the two items together no magic to the

tool oiler either it’s got a reservoir in the bottom where you can put your

tool oil you probably can’t see it but there’s a hose that runs up here

connects through this valve on the back of it which by the way the instructions

say that you have to just the oil supply valve but they don’t

tell you whether this steel screw in the back or this plastic screw in the front

is the adjustment valve so you have two options you can either just turn a thing

upside down and look at where the hose goes in and it’s pretty obvious that

it’s this thing in the back or you can guess try to turn the plastic thing find

out that it snaps off as soon as you try to twist it and then have to go buy another oil fogger

don’t ask me how I know that anyway depending on where you have the valve as

air passes through here the venturi effect occurs down inside the body of

this thing and it draws oil up the tube and eventually you’ll see droplets form

on the end of the copper and then when the drop gets big enough it falls off

and lands on a vaporizer pad that’s inside of there how much oil is the

right amount of oil I have the foggiest idea some if you read the directions for

the tools they’ll tell you to put a couple of drops of oil in the thing

every hour of operation which of course makes no sense because there’s no way to

know whether you fired one or a thousand nails in that hour but I opened it up

until the oil drops down there you know one drop every hundred shots or

something like that anybody knows that that ought to be different post a

comment let me know because I’m just guessing here folks finally I installed a quick release

fitting on the output here this allows me to plug in right now I have this got

off of plastic coiled hose just for demo purposes but when I get out to the shed

I’ll be able to switch back and forth between a twenty five fifty hundred foot

hoses just so that I don’t have to have any more hose than I have to have to

drag around add weight kink up whatever and restrict airflow to the tool that’s

it the whole thing is easy it’s pretty cheap the only thing you actually have

to make is whatever kind of a bracket you’re going to use to attach it to the tank itself

unfortunately the legs that are welded onto the bottom of

this thing don’t come tangent to the sides of the of the barrel so you have

to have a spacer and then the piece that comes up to come out your stuff on I

made mine out of scrap plywood metal plastic probably play-doh would work

it’s not a not a big deal speaking of work it works I haven’t put

it into service obviously out on the the big project yet because I’m not to that

point in the project so I may post a follow-up or comment or something after

I put a couple of hours on this but I think it’s going to work out pretty well

I definitely am gonna like having local adjustment of the pressure the oiler is

necessary and I’m glad I have a way to put it in and out of my circuits easily

and the tank I’m not gonna miss it yeah I still have a tire truck that I could

actually put on the end of this hose so all else being equal you know worst case

scenario is I would put a little oil in my tire if I had to so that’s it.
