The AirSpeed tubes are quick and easy to change, so that you can carry on with your camping holiday as soon as possible! Simply remove the old tube from the beam sleeve and replace with the new tube. Vango never comprise on quality, so you can feel confident that these products have been thoroughly tested and are built to Vango's exacting standards. It's always a good idea to keep a spare AirSpeed tube with you to ensure that your holiday doesn't come to an abrupt end. You will simply need to secure the valve in the correct location and fold back the excess before inflation, the housing sleeve will stop the tube from expanding any more than is required. Important:Replacement tubes will be supplied longer than the beam sleeve length, in some cases the replacement tube may be slightly longer and wider than your original (upto 80cm longer). I measured 11A current draw at 7PSI output pressure.This item is a genuine Vango product, manufactured from 100% TPU Tube with the AirSpeed Valve system. Since this unit is rated by their own admission at 13.5A, the 10A relay is likely to take a real beating over time. This also gives a hint to the actual manufacturer of the pump – with the model number HB-630A. Here’s an overall view of the power control board, with a better view of the pressure sensor & relay. Max packsize of: L82.0 x H54.0 x W60.0cm Pitching Time Have this pitched and ready to go in around: 20 mins Capacity This 6 Person Tent has lots of room to move around AirSpeed® Valve Inflate and deflate your tent effortlessly in minutes with the unique and conveniently positioned va. Power is handled by a small linear regulator at the bottom edge of the board, with a couple of large electrolytics for filtering. The pressure sensor is on the right, although I haven’t been able to decode the laser-etched number on the top. The microcontroller is an Atmel ATTINY24A with 2K of onboard flash. I’m not going to take this one off, as zebra strips don’t usually work properly once removed. Underneath hides the LCD controller itself. The display is a standard 7-segment LCD, with a zebra strip connection to the PCB.
The power control board has a 10A relay to switch power to the motor, along with a small microcontroller & pressure sensor, which is under the plastic adaptor on the PCB. The electronics are on a pair of PCBs tucked into the upper cover, one dealing with the pressure measurement, microcontroller & power control, and the other dealing with the display & buttons. The 20 minute limit on operating time most likely has a lot to do with the almost entirely plastic construction – the adiabatic heating of the air as it’s compressed will make short work of the relatively low melting point of the Nylon. Plenty of grease has been applied to the moving parts at least, to help keep the friction down. The working cylinder & piston are also made of plastic, so I don’t hold up much hope of this unit wearing well, even though the plastic feels like Nylon 66, glass fibre reinforced. Ball bearings are used on the crank gear, but it appears that the big end bearing is a simple bushing on the steel pin. The driven gear is made of plastic, most likely nylon. CrankshaftĪfter the cover has been removed from the pump unit, the main drive is visible. This motor does have some cooling from a fan on the armature. The drive motor has the same model number as the overall pump, likely made specifically for this unit. The outlet valve is hidden inside the tube. The valves are located on the end of the cylinder, the right hand on is the intake valve, the right is an pressure relief valve. The internal parts of this pump are almost entirely made of plastic – not what I’d expect for an air compressor. I expected this to be a centrifugal blower, but instead it’s a large reciprocating air compressor – even if the construction quality is a little dubious for a device that costs over £70. Here’s another piece of tech, the electric air pump that’s available as an optional extra with Airbeam tents.
