Tyre Inflators

There are also many other brands that do the same.

I agree, but the last one I bought was a total dud and it cost almost as much.

I have an AEG unit from Bunnings, it uses my drill batteries and as absolutely brilliant.

Thanks, I have the need to purchase another Milwaukee to ad to my collection

They are worth every cent. They are small, light and compact and really quick. Accurate too. Just set the required pressure, hit the button and away it goes until pressure is reached and then cuts off.

G'day BigD, long time no hear.

Any chance of a pic mate? I have Ryobi stuff and have been thinking of what I think is the same thing but Ryobi. They have 2 different types. I mainly want it for top ups. My Old TJM pump has been pretty useless and still is, so time for an upgrade me thinks. Pity I can't upgrade my body as easy smile

Keep Safe on the roads and out there, mate.

I purchased a Combo Kit a drill and impact wrench on a special deal.

It came with a free tyre inflator,it comes in quite handy for topping up tyres.

Maybe not so good for serious 4WDriving but very happy with it.

If I deflate my 4 tyres to 24 psi, would the battery have enough charge to inflate my 4 tyres back to 38 psi?

Thanks Alan, if that's the same as DMaxer's, it looks a similar contraption to the Ryobi one I'm thinking of.

That sounds like a tough ask for the typical 4WD wheels with large air volume and high pressures.

I have a twin cyclinder 12v 60 amp pump which connects to the car or van battery. At a guess it would take about 3-4 minutes actual pumping time for each wheel. Say maybe 15 minutes for the four. That means around 15 amp hrs from the battery (actually more because of the high discharge rate).

My recollection of 3-4 minutes may be off because I have never timed it, and it's been a while.

Maybe you would also be deflating van tyres for corrugated roads.

It sounds like a great solution for smaller wheels, just doing one wheel, or top up the pressures.

That one is pretty much similar in size and shape to the Milwaukee 12 Doug. If you go onto the net there is a video of a bloke giving the M12 a test run. Just type in Milwaukie 12 inflator test and you will see it. He pumps up 4WD tyres from partial to full inflation in minutes. I inflated the tyres on the van from 38 to 45 in about 20 secs each. You can only run it for 10 minutes then it needs to cool down. It sounds like a kitchen blender when it is doing the business.

Thanks Mate. I had a peak at that video and seems OK for what I want. A little noisier than I thought they would be though. I will track down a Ryobi video and see if any good.

If you intend getting a cordless air compressor the Milwaukee M18 is not only 3 times faster but will inflate more tyres, cost more but faster and longer lasting.

My 3 ARB compressors in parallel use up to 90 amps, but about 80 amps as per clamp meter on average inflating a tyre.

25 seconds to charge my system including 4 litre air tank & a lot of air line & aftercooler, to 135psi as per regulator/moisture trap shows.

From 20psi to 35psi 28 seconds per tyre, about 65 litres volume each tyre, while engine running. Voltage is 14.4 volts. So about 2.5 minutes to charge system & inflate 4 tyres.

80 amps x 14.4 volts = 1152 watts

1152 / 12 volts / 60 minutes x 2.5 minutes = 4AH

I have the Ryobi hand held type that uses the Ryobi plus one batteries. It is great for topping up your tyres and has a reasonably accurate digital pressure gauge on the back. It is not savage on batteries and would easily pump up your tyres from quite low on one 2 amp battery but is quite slow as it is not a high volume pump. If you are regularly dropping tyre pressures in your 4WD to go beach driving this is not for you. Buy a large Kings 300 litres per minute pump for that. The Ryobi works well for that top up or in an emergency but I wouldn't like to be pumping up 4 4WD tyres from 15psi on a regular basis with it. I bought it to pump up my wife's wheelchair tyres and the occasional top up of van and car and for that role it is brilliant.

I have been using one of these for 17 years and we air down a lot.

I also run it continuously sometimes to power the ARB diff lock.
100% duty cycle and fully rebuildable (but it has never needed attention).
Cheers,
Peter

Wife and I are regular scuba divers and we have bits of that type of kit left around. Years ago I added a tyre inflator end to a second stage (mouth piece regular end) with an older first stage regularator to fit to a tank.

Sometimes we take a scuba tank and the tyre inflation reg set with us in case we need a quick inflation. A full scuba tank typically is around 3,000psi. First stage regularator gives about 120-160psi in the hose. A used scuba tank typically has 750psi or more residual air pressure.

This week, I made use of the inflator reg to inflate a Suzuki Jimny tyre after repairing a puncture. The scuba was about 1400psi to start. The tank's internal volume is 12 Litres. A very quick inflation.

PS -- sorry about the photo orientation, it showed correctly as I attached the picture file.

Remember that if a compressor states, say 300 litres per minute it will be at 0psi, & states 150psi will be 0 litres per minute. Both useless numbers.

Compressor should state SCFM (Standard Cubic Feet Minutes), let's say 20°C at 90psi. In other words a useful pressure & volume for most air tool applications.

PSI vs Litres per minute:
