I've managed to inflate m/home tyres to 5 Bars plus, sometimes from flat with quite small 12v inflators by limiting The Ring RAC700 4×4 Air Compressor weighs a hefty 2.091kg and measures 175mm high, 200mm wide and 130mm deep. Downside is cost (though I think it's very reasonable for the quality on offer) and bulk - it comes in a bag the size of a rugby ball.

Below are the three Inflation Adapters included for inflating balls, airbeds, paddling pools, etc.: Inflation AdaptersUnfortunately, the Screwfix master plug is as stated a 10A rated item, whereas the Ring RAC 900 the OP has is rated at 30 Amps, massively higher. WARNING: Tampering with the safety valve or hose connection at the compressor is likely to invalidate any guarantee and may introduce safety issues so I will not recommend it. It measures psi (pounds per square inch), BARs and kg/cm 2 Carrying Bag For The Air Compressor RAC900 When I’ve finished inflating the tyre to a higher pressure than required I measure the pressure with a gauge I trust. One like a cylinder with a piston that is pushed out after the pressure has worked against a spring. Then I let the pressure down bit by bit until it is correct. Those gauges have a shaped knob on the end to press the tip of the valve in to let air out. These are called pencil gauges, e.g. pencil gauge

Sorry to hear your yellow hose is damaged and needs replacing. You could try binding the hole with several layers of good PVC electrical tape if the pipe is clean and the holes are somewhere away from the connectors on the ends. The robust metal body and anti-vibration feet make this a durable inflator, ideal for trade use. Has an analogue dial that shows pressure in PSI, kPA, bar and lb/cm2. Comes with valve adaptor set and storage case. But while the speed is great, niceties such as a digital gauge, an auto-stop function and lights, are conspicuous by their absence. On the plus side, you get a 7m-long coiled hose between the compressor and the screw-on tyre-valve coupling, and the compressor itself can be up to 2.4 metres from the battery, thanks to long power leads that clamp directly to the battery’s terminals. Likewise, the three minutes 20 seconds inflation time that the Ring RAC700 took to get our test tyre from flat to 30PSI is slower than a professional product. For our test we used a 205/55 x 16 tyre.I’m not 100% sure its a metric thread but it was made in recent years within the EU. My next best guess would be an NPT (National Pipe Thread), but I can’t see a taper on it. The auto stop feature ensures accurate inflation. It is easy to use: set the dial to the pressure you need. Then press start. The inflaton with automatically stop at the prescribed pressure. The inflation rate quoted is ‘under four minutes to get a tyre from flat to 35PSI’. By contrast, the Ring RAC900, for instance, takes just one minute and 40 seconds to inflate a tyre to 35PSI.

the process to short stages, letting the pump and power cable cool off. Admittedly you've got to have patience, but So my “slave battery “ option is not unreasonable, but has payload issues, if you have payload issues with your van. If you can’t find the help needed on our DIY blog then why not head over to our forum where you can can help from both tradesmen and other DIY experts. The average car battery may have a capacity, when new, of 50 Ampere Hours, i.e. if you connected a device that would draw 25 amps (and the RAC900 draws 23 amps) the battery would be drained in 2 hours.

Unfortunately that’s where the similarity ends, because with this Ring RAC700 the compressor-mounted gauge, standard-length air hose, and 12V plug on the power lead are all much more like the budget DIY models on our test bench. The Ring RAC900 is a heavy-duty, high-powered inflator. Used by leading UK breakdown professionals, this has all the power you need from a robust inflator. Save money and stay safe Tyres will gradually lose pressure and most people's requirement for a tyre pump will be to 'top up' that pressure occasionally. A 12V pump is ideal for that purpose, but, to handle the pressure and volume of air in a motorhome's tyres, the pump needs to be a good one. I wouldn't have thought that the 42 seconds the on-test RAC-900 took to inflate a motorhome tyre from 50psi to 60psi can be classed as "an eternity".
