THE AIR TRAILER AIR DRYER IS A MECHANICAL AIR DRYER THAT INTEGRATES AIR TREATMENT, DISTRIBUTION, AND INTELLIGENT CONTROL INTO A SINGLE UNIT.

This design eliminates multiple components, reduces weight, and minimizes failure points. It also features an intelligent drying cycle system and an electronic control unit that offers flexibility and ease of use.

 

The  trailer air dryer has a patented multi-treatment cartridge that eliminates oil and maintains a dry air brake system. Other key features include an integrated air governor and system check valves. It also eliminates a separate purge tank, which reduces maintenance costs. In addition, the modular design makes it easy to service and replace parts.

 

 

The air dryer control module restores the air brake dryer to like-new performance. The module features stringent quality standards, which ensure durability, reliability, and efficiency. It is compatible with the  AD9 air dryer system and has a retrofit kit included.

 

 modules are designed to work in tandem with other air dryers. This ensures that the system has maximum capacity. The air tanks on trailers with air accessories are designed to handle the added capacity. For best performance, the module should be used with trailers that have air accessories. Using the  module will ensure that the air tank capacity is not compromised. The module also reduces the risk of air line breaks.

Donaldson coalescing cartridges

 

Donaldson air dryers are designed to provide the highest levels of protection against damage. They work by removing water, oil vapor, and other contaminants. This prevents equipment corrosion and freezing, and helps to extend the life of air valves and other components. The air dryer must be properly maintained and serviced to ensure its longevity.

Service reservoirs

 

Trailer air dryers utilize service reservoirs to provide compressed air to the trailer's air system. These reservoirs are typically connected to the towing vehicle, which is usually a truck tractor. In combination vehicles, one truck supplies air to several trailers. The service reservoirs and the air dryer are connected via a hose.

 

The service reservoirs are monitored by the governor control 30. When the reservoirs fill to the desired level (e.g., 840 kPa), the compressor switches from the pump-off process to the service reservoirs. This cycle repeats until the driver terminates the pump-off operation. While the reservoirs are being filled, the compressor runs in the 100-200 kPa range and runs at lower pressure when the reservoirs are empty.
