"It seems the Expello valves are working well. I ran the engine while under the rear air tanks. The accessory tank spat simultaneously with the air dryer, and the brake tank spat approximately 20 seconds later. No moisture from either tank. So the air dryer is doing its job and so are the Expello valves!" ~ Mark Bragdon.
