Why Use an Inline Water Trap?

Even when your compressor is fitted with a tank drain or main filter regulator, moisture can still form inside the airline as compressed air cools. An inline water trap fitted directly before the spray gun provides a final stage of protection, helping to prevent water reaching the paint surface and ensuring a cleaner, more professional finish.
