Kampa Pro 330 awning blows up

I have the 390 model and unless some are different there is an inlet valve on each leg

Ummmm!!! interesting, mine is perhaps 4 years old, there is an outlet on each leg, but only an inlet on 1 leg, 1 of the middle legs, unless you are saying the outlet can also be used as an inlet which i doubt very much ??? 

i should say that in the 4/5 years we have had the Kampa 390, i think i have now replaced all 4 legs, 3 were done under warranty and i sent the whole thing back to Kampa for them to fit, although it is a relatively easy operation. Mine stands for long periods in the hot sun, e.g. 6 weeks and i dont think this is ideal. The whole thing has faded very badly, i call it bleached, but would never go back to poles 

My 2017 390 only has one inlet. Three deflation points. Mine too, is very faded as it's up for six weeks in one go in the summer.

Seems to be a reoccurring issue with Kampa air awnings. 

Glad I opted for the Bradcot Air Aspire model...............

I have a picture on my phone taken a few days ago of a Bradcot Module air flapping in the wind, gone bang!

I bought a full awning a few months ago, went back to steel poles, no regrets.

Can you post the picture ?or it makes one wonder about numerous of your posts

Perhaps the difference is I inflate mine with an electric pump which cuts off at the pre set pressure, which is somewhat lower than the Kampa recommended pressure.

Couldn't be doing with all that scaffolding erecting with the old fashioned ones 

I like our steel poled awning, bought it to add more weight to the car. Michelle and myself work well together, I also use a 3 step ladder and awning tensioner for final fix, and it has no guy ropes!

When we looked at awnings we did examine the Modul Air and Kampa's 390.

Bradcot all the bladders are connected with no valves, so if it has a puncture it all goes down. Kampa you can isolate a bladder.

 The picture shows the main section all deflated, with the front add on still ok.

Adding this picture wasnt an easy task using a mobile phone!

Sorry to tell you but I know of 2 Bradcot aspire air awnings that have gone with a bang. 1 on  rally at Jervaulx Abbey and the other on a rally at Kirkby Stephen both were Aspire Air 390’s. I do believe that the Bradcots have a lifetime warranty for the bladder.
