Is a Water Trap Needed for Air Bag System

Question:

Should I install a 1/4” water trap inline with this system to reduce the likelihood of moisture getting into my air bags?

Usually a water trap is not needed for an air bag system. In fact, my Firestone contact told me they never recommend them!

One exception might be heavy continuous use in a humid climate, such as a work truck used daily in Florida or Louisiana with pressure changes being made all day long every day. In that case a water trap might be a good idea.

But for a vehicle occasionally towing the same RV on a recreational basis the air bags will not be likely to accumulate enough water to worry about.
