Ring Heavy Duty Tyre Inflator - High Power Air Compressor as Used by Breakdown Professionals

....on a compressor, and this is the one you should spend it on!I bought this after reading reviews on a few sites,not just on here. Nearly all said that this is an excellent piece of kit, and they were right.I bought this compressor because, as a caravan owner, I regularly need to inflate my car tyres at home and on site. I was fed up with paying £20 or more for 'top of the range' foot pumps, and having all of them wear out in no more than 18 months. So, add that up and it probably comes to more than I paid for this one.The compressor comes in a very useful bag, and the kit is lighter, smaller and quieter than I imagined. It inflates my tyres from around 30psi to 47 psi in about 2 1/2 minutes. Very quick and easy compared to anything else I have used at home. The couplings are all good quality and everything seems geared to professional use. The valve attachment is a screw thread, so you don't have to wait at the tyre when inflating. It can also be used to deflate as well. Check that you can access your battery easily because the unit cannot be plugged in to a lighter plug.I am very pleased with this kit. Only time will tell though........I rated it as four stars because I have only owned it for a short while.16/09/2012 I have changed the rating to five stars now. I have been using this for six months, and it is a quality product. Light enough to take away on caravanning holidays and certainly up to the job I bought it for.

This pump is great, you can take it with you everywhere.It is perfect to pump up a soft wheel at anytime.It also has no problem going round the whole vehicle.

Having owned and used several consumer-level tyre inflators over many years of car and motorcycle use, i started looking around for a replacement when the last of cheap ones died.I wanted something that was durable, not encased in cheap plastic, with long cables and hoses and good durability. And a mechanical gauge. No batteries or electronics.The Ring RAC900 delivers all this and more.The unit itself is reassuringly solid yet compact. The cylinder has cooling fins to enable sustained operation. Hardware is all metal. Nothing plastic to break off with age or chemical / UV weakening. Even the power switch is protected from the elements by a transparent rubber cover.All air fittings have a reassuringly solid feel, from the heavy rubber outlet hose at the compressor end through the coiled extendable hose to the brass push-fit connections. There's even a proper analogue air pressure gauge encased in protective rubber.The power cord is long and the crocodile clips of a good size and solid construction.In use, the unit is noticeably quieter than all my previous inflators. It makes very short work of pumping up tyres. Better even than some garage forecourt ones. I added 20PSI to a space saver spare in probably 30 seconds.The supplied pressure gauge is not too accurate, however. I stopped the inflation dead on 60PSI, then measured the tyre using a calibrated gauge, which showed just over 55psi.Still, that's a little under a 10% discrepancy, which is very acceptable for a unit of this modest price.The whole thing is housed in a fitted durable looking bag, which is a far better option than the usual blow-moulded plastic case that you tend to find on consumer products.Even at the full price this is a bargain. At the £79.99 that I paid, it was a steal.Highly recommended.

Needed a new inflator for 7.5 m Motorhome inflating up to 80 PSI small enough to stow away and big enough to cope, and this seemed to fit the bill.It connect to the Vans (Fiat Ducato) jumpstart point under the bonnet. With the long flex tail it just reaches both rear wheels. (About 6 m)I had to deflate the tyre to about 70 PSI to test it and it inflated back to 75PSI in very short time. Didn’t time it, but less than a minute so a great study product.Now for the negative.Would be great if the el cable were a bit longer, 7.5 m Motorhome is about the limit.The gauge is very inaccurate. You will need an alternative gauge to check the pressure.It would be nice if the gauge came with switch off. On this version you have to connect the tube. Walk back to pump to switch on, then return to check the pressure, which seems about 5-7 PSI above what you want, then return to the pump and switch off. (Or be two of you)In conclusion. The pump is great, the attachment has room for improvement.
