Air Pumps

I think that some time ago there was one or two reports on here about on-board air pumps for quick inflating of tyres. I can't remember what was said or recomended but seem to remember that there were some high pressure pumps available and a web site mentioned.
Can anyone with a better memory than mine, or who has some info help out please.

  1. Hi there, You could use RangeRover P38 air suspension pump,or any air suspension pump old Renault Ambulance type, Sherpa Van.  Huge Amps demand! You will need some BIG cables. Cheers Steve

  2. I use one of these:   http://www.paddockspares.com/pp/NEW_PRODUCTS/T-Max_Compressor/T-Max_Portable_12v_Compressor_(SOLD_OUT).html   but it looks like the title gives it away - they might be getting some more I suppose.  Excellent item - works well, blowing a 175/80/14 tyre from 6psi to road pressure in 20 sec or so.  And tow car spare wheels (doesn't it John?) as well as trailer tyres . . .   Second hand air suspension pumps were going for rather more than double that when I was looking - seemed a good idea and so far, is.   Bri

  3. http://www.cbdevelopements.co.uk   Chris Sawyer is a trialler....his kit is top quality, but of a price......would cost more than my whole car.   The basic air pump setup is fine.

  4. These get you fit at the same time, don't draw any amps and are completely reliable.  You can choose between low pressure (up to 144 psi) and high pressure (200psi+) versions.  Less than 2kgs... http://www.chickencycles.co.uk/index.php?cat=30&sub=53&ord=2

  5. Don't dismiss Ian's posting as a joke - I've used a bicycle track pump, in preference to a car foot pump, for inflating car tyres for years. If you get a "mountain bike" one (designed to pump larger volumes to lower pressures) rather than a "road bike" one (designed to pump smaller volumes to higher pressures) it will be at least as quick as a twin-barrel foot pump and somewhat easier to use on rough ground. However ... the real answer to rapid post-section-ends tyre re-inflation is CO2 bottles, if you can find them, and a source to re-fill them.   Andrew

Cheers Steve     By a happy coincidence I found a Renault Ambulance in my local scrappie a couple of weeks back and removed a virtually new Dunlop branded air-pump from underneath. Steve, what sort of amperages are we talking about ?

  7. I bought a very good American branded air pump from Adrian Marfell. It is designed for blowing up Off Roaders tyres. It is very compact and I have mounted it on the back of my Troll. It draws a large current so good permanent connections are required. It blows up my 165 x 15 tyres from around 8 psi to 20 psi very quickly. I can reccomend one, contact Adrian. Stuart Harrold

  8. If for any reason I can't get the Dunlop one to achieve decent times then that could be a good contact. What sort of amps is your pump actually taking, Stuart ? Give my regards to Richard when you are next at a Club Night ( I have tried to persuade him and Celia to enter the modern age of computers and emails but to no avail !)

  9. I have a T Max pump from Paddock Land Rover. It is certainly one of the quickest electric pumps around. The instructions with it advise that you keep your engine running when you use it as it draws 30amps! Ed

  10. I use a Range Rover air suspension pump. They are expensive new but can
    sometimes be obtained pretty cheaply second hand.

  11. Got the on board compressor from a Land Rover bits supplier called Matt Savage. It was a few years ago when he had a small range. Just looked on his site http://www.mattsavage.com/acatalog/compressors.html and see he now offers a lot more models and installation kits. I just have the compressor, no tank or anything, so I have to be careful not to pump against a closed valve. I know some people avoid this by using a spare tyre as an air tank.

  12. Michael, do you have any idea why that post took about 3 days to appear?

  13. Les - No idea, its usually instant. If it happens again give me more info - Michael

  14. The information that came with mine says it can draw up to 30 amps. I have fitted a 30 amp fuse in line. I always start the pump then connect to the tyre so the pump starts against no load. I generally switch off my electric cooling fan when pumping up. At night I tend to turn off the headlights when I have the pump on. To date no problems as generally the pump is only on for a couple of minutes and the alternator quickly tops up the battery. Stuart Harrold

  15. Dual batteries?   Increased  output alternator?   convert to 24 volts?   donkey engine?   the possibilities are endless.
