Compressor

Overdrive!
Need an air compressor for tyre inflation. Have seen 2 so far, the Truckair 300 and the T-Max Compressor. Has anyone any info on either, any comments, which is the best one bearing in mind it will need to be able to inflate a 265/75 on to a rim.

Thanks in advance

To put a tyre onto a rim it's not about a compressor its about the amount of air and the pressure, it's takes a lot of pressure to put a tyre onto a rim. Where as using air tools such as impact wrench and such uses a large mass of air so you need a compressor with a large CFM (Cubic Foot per Min). But sorry don't know which one is best but for tyres you'll need quite a large tank!
 
Looks like it might be the Truckair, see spec below, like the idea of continuous use. Anyone have any preference.....

Motor Torque at Maximum Power
3.48 in. lbs.
​
Max. Air Flow
47 CFH
​
Max. Operating Temperature
165°
​
Diameter of Motor
2.04"
​
Air Displacement of Cylinder
.49 Cubic inches per stroke

That thing wouldn't blow up a frog with the airline up its ar$e never mind a tyre :D

47CFH thats .78CFM and that won't be Free Air Delivered rate either. Waste of time my friend

Wish you hadn't said that, I've just bought one from graemelliott :( .

Seriously though, the TruckAir is a hang of a lot quicker at re-inflating my 31" Grizzly Claw tyres from 20psi [off road] to 32psi [on road], than the poor old Halfords machine. Although to give the old machine credit, it has been reliable enough and is originally meant for "topping up" the odd Punto / Micra tyre.
 
How about buying an old diving tank and filling that with air. You can fill them from an ordinary compressor I think.

Cheers, Ben
 
I have sold loads of the T-Max compressors, great little units but no good for beading a tyre on the rim.

The diving bottle, fire extinguisher or gas bottle is an excellent idea but you obviously have a limited supply.
 
what you want is 1 or 2 air tanks off a hgv/psv.
I am going to get 1 or 2 off a coach company i work part time and being small in size they can be fitted anywhere.
I plan to inflate them using my compresser at home and holding 120 psi each i will have enough air on hold.

If in certificate then a 11ltr tank at 300bar would have a fair bit of air in it. However an 11 ltr tank with cert will set you back £125+
 
As others have said - you need reserve capacity and high volume feeding your reserve. Cheap electric compressors wont give you either.

For full onboard-air systems we supply 8cfm or 10cfm engine driven compressors to give the volume and certified air resevoirs to give the reserve... plus all the other ancillery bits obviously!
 
Never had a problem with my "TruckAir" it does the job i require it to (reinflate my 235/85/R16's and the occasional double airbed), hasn't let me down so far (unlike cheaper models which kept cutting out due to overheating), so i don't plan on trading it in any time soon.

Free air flow 70 LPM

Or 50 LPM @ 30Psi

:rolleyes:

A bit better than the other make but still only equal to

70LPM = 2.472027CFM

50LPM = 1.765733CFM

An average Hoby/Home Compressor at 8cfm would take a 2/3 minutes to fully inflate a large tyre as used on a Landie, and that would be based on a 30 to 50ltr tank
 
The choice I guess comes down to two things: Need for speed & reliability.

If you need speed or reliability then engine driven high cfm compressors are the way to go. If you only need to top up a tyre once every 6 months then a cheap electric one will probably do.
 
wondering if i can rig up my Tmax to a small diving cylinder i have for my air rifle , fit it in the car for occasional airing up and down .....shooting , and air tools ........would be a perfect all round set up if it could be plumbed in ?
 
pak... PM jkelly or wait till he replies, he has some really neat air compressors, HQ (rescue that is) are really tryin to fetch the funds to get a compressor off ventureoverland for BA set filling. (u wouldn't need such a pump as we're looking for breathable air and quickly filled but if they can offer such a compressor, they for sure have quality products!)
 
You would never get the perssure with one of these units to fill a BA Bottle. The Compressor needed to fill them are very expensive and top out at over 3000psi.

The cheapest way to do this would be to have a couple of BA Tanks and get them filled to their working pressure when needed. it only costs a few quid a tank. You would then have 11 liters @ 200bar + that would inflate a few tyres
 
I had to repost this as the admin wont let you edit after 5mins :shake:

Everyone is forgetting it is not the pressure supplied but the Free Air Delivered rate that counts, most compressors and supply 120psi, however the amount of Air they can supply at that rate is dependant on the size of the Compressor itself

Air tools consume a lot of air 4CFM+ @90psi your breathing tank would not last very long.
