Having a water trap to stop moisture mixing with your paint will always be more beneficial over not having one, but if you only do a little casual airbrushing in an environment that’s not overly humid then you should be fine without one. Typically it water trap will be a small glass bottle situated between the compressor/tank and your airbrush, most often bolted directly to the tank or frame it’s held in. Personally I think they are a waste of money. When you consider how many vents are in the average modern van all you will be doing is removing moisture from the air for it be replaced by more coming into the van. The important thing (as mentioned above) is to correctly winterise the van if you aren't going to use it for sometime as most of the issues you can get won't be of concern during the spring & summer when the van is in use. They won't stop damp in a van as this (as mentioned above) is caused by water ingress, normally due to a leak on a seal somewhere.

For a trap to be of any benefit in removing moisture it would require that the air in the caravan be static, due to the natural ventilation from around the windows and the holes in the floor, the air in the caravan changes on a regular basis. You will typically need to spend more money to get an airbrushing compressor that has a water trap already installed on the tank, as these types of compressors generally come with many more features overall.Be mindful of this when you’re deciding on what compressor to buy and consider what the humidity is like in your own area – the higher the humidity, the greater the need for a water trap on your airbrush compressor. 👍 While this result occurred due to high ambient air humidity, you may find that you are much more susceptible to this with lower air humidity if you don’t use a water trap on your compressor.

It is by the nature of the crystals in the trap that they attract moisture, so you could place on in your kitchen and see it fill up. A suacer of salt will do the same. This can be a problem when the moisture trap is attached directly to the compressor (and is perhaps a little more prevalent on smaller compressors), and is a function of temperature and pressure. As discussed in the prior section, if you’re airbrushing in very high humidity air as you might find in tropical areas or on a very rainy day, the moisture in the air can affect the paintwork regardless of whether you’re using a water trap or not.
