Air Suspension Pressure?

[Christy]

Hi,

I have recently bought a motorhome with Dunlop Auxiliary Air Suspension. It is a 2012 Swift Sundance 3500kg

The pressure gauge for the suspension is currently reading 2 bars. Any recommendations on what it ought to be please?

Thanks

I’ve had my Easytops on exactly that and am v pleased.

We run between 2.5 and 3 bar. 2001 Hymer 3850kg
Best just try different pressures and see what suits you.

2 - 2.5 bar.

2.5 - 3bar Adria Matrix 3850kgs

It should be just enough to maintain your ride height so varies with load .

Around 2 bar is what we run our PVC motorhome.

Between 2.5 to 3 bar on ours and if it's blown a blowing a hooley, around the 3 bar mark.

Long way around to do it. Empty the van completely water, All loose goods bedding tv etc. Air bags at 1.5 bar. Measure height from rear jacking points to ground. Reload van with all you would normally carry, full gas bottle, water, fuel. Measure height again pump up air bags till same height as empty van, you will find that about right. At 3500 kg too high will not give you the best ride.

Mine has sat at 20psi, since purchase. (rear only) Just takes the "Hard" out of the ride.

Don't run at less than around 1.5bar (approx 22-23psi) or the air bags can be damaged.

Don't run at less than around 1.5bar (approx 22-23psi) or the air bags can be damaged.

This is what the installer of our last air system told us .
Running with low pressure can damage the bags

Hence the reason to start at 1.5 bar, when loaded if you are at the same height as empty at 1.5 you remove the risk of damage running the air bags at too low a pressure.
