Air Dryer Wet Tank

It is usually.

Air dryer wet tank. Install a general purpose air filter between the wet tank and dryer and a coalescing filter after the dryer. Wet air storage before a dryer dry air storage after a dryer air compressors 10 horsepower and smaller are usually mounted directly to receiver tanks. If wet receiver capacity is installed then the flow of air in the dryer and filter is smoother. On compressors without integrated dryers or without a dryer in the system your air tank may end up with moisture in it untreated and wet compressed air can lead to damaged equipment and compromise the quality of your product and it can similarly affect the air receiver as well.

It will purge at maximum pressure and it is a filtration system that is filled with desiccant and as i said in the introduction these air dryers can be located in number of places on the vehicles. As mentioned above it is best to have wet and dry receiver tanks. View profile view forum posts diamond join date feb 2003 country united states state province illinois posts. This takes some of the moisture and contaminate load off the air dryer and its associated filters resulting in better compressed air quality.

Since the air going through the filter is cleaner and dryer than it would be directly out of the air compressor slugging of the filter with liquids is minimized along with resulting pressure drop on the air. Locating the storage tanks on the wet side of the air dryers and filters provides a location that allows the compressed air to cool and drop any free water and lubricant in the quiet zone inside the vessel. There should be less or no water dropping out in the dry tank so the air will be ready for large events. Deliquescent air compressor dryers have a single tank and also use a desiccant but they can only provide a pdp of 20 f to 25 f lower than the air temperature entering the dryer.

When the compressed air enters the tank it reacts with the desiccant material to produce a liquid effluent that needs to be drained out of the dryer and disposed of. A wet air storage tank prolongs the life of the pre filter element located in between the wet storage tank and the dryer by removing excess liquid and. Peak demand from events from overloading the dryer. When the compressor is unloaded there is some flow coming from the receiver which slows the step changes.

So older air brake systems are going to have a wet tank. The air dryer is going to be between the compressor and the wet tank. The compressor outlet feeds directly into the tank. The receiver tank sizing rule of thumb for small systems is one gallon per rated scfm 100 psig.

Stored air is pre dried and pre filtered so it will reduce peak loads from effecting the dryer. Without a wet tank the air dryer and filters see a step load changing from zero to 100 flow every time the compressor loads and unloads. Wet storage increases the efficiency of your air dryer by allowing excess water and lubricant to condense out of the air before it hits the dryer. A wet air storage tank also prolongs the life of the pre filter element which is located in between the wet storage tank and the dryer.
