The Portable 12V High-Capacity Aftercooler with Water Trap for 250–450 CFM compressors is a heavy-duty, mobile air cooling and moisture management solution developed for high-output compressed air systems operating in demanding field conditions. Built on the same proven design principles as smaller portable aftercoolers, this unit is scaled to support significantly higher airflow while retaining portability, durability, and ease of integration with mobile compressor setups.
Designed to operate on a 12-volt DC power supply, this aftercooler is ideally suited to large trailer-mounted and vehicle-mounted compressors commonly used in abrasive blasting, aquablasting support, industrial surface preparation, and high-demand pneumatic applications. With the ability to manage airflow between 250 CFM and 450 CFM, the unit rapidly reduces compressed air discharge temperatures, encouraging effective moisture condensation before air enters downstream hoses, blasting equipment, or control systems.
Effective moisture removal is critical at higher air volumes, where elevated temperatures and airflow can quickly overwhelm standard filtration. This aftercooler incorporates a high-efficiency cooling core designed for continuous-duty operation, paired with an integrated water trap that captures and separates condensed moisture from the air stream. By delivering cooler, drier air, the system helps protect downstream equipment from corrosion, prevents media blockages, and improves consistency in blasting and tooling performance.
Despite its higher capacity, portability remains a core feature of the design. The aftercooler is mounted on a reinforced steel frame engineered to withstand harsh site conditions and frequent relocation. Heavy-duty rubber feet isolate vibration, reduce noise transfer, and improve stability during operation. An integrated carry handle allows the unit to be repositioned easily on site, while the compact footprint ensures it can be accommodated alongside compressors, air dryers, or blasting systems without excessive space requirements.
To support a wide range of compressor configurations, the unit is supplied with a comprehensive connection kit that includes hoses, fittings, cables, and adaptors. Power connection options include heavy-duty alligator clips for direct battery connection, as well as an Anderson-style plug option for compressors equipped with compatible auxiliary outputs. This flexibility allows rapid setup without permanent modifications, making the aftercooler well suited to hire fleets, contractors, and multi-machine operations.
The water trap is designed for easy access and routine draining, allowing operators to manage condensate efficiently during long run times. This helps maintain consistent air quality throughout the workday, even in high-humidity environments or extended blasting operations.
Typical applications include large-scale abrasive blasting, infrastructure maintenance, marine and offshore works, pipeline preparation, and high-volume pneumatic tooling. When integrated into systems aligned with Brüder’s POWER FULL AIR approach, this high-capacity portable aftercooler supports efficient air management by reducing thermal load, controlling moisture, and maximising usable airflow from high-output compressors.
Key features include suitability for 250–450 CFM compressors, 12V DC operation, reinforced portable steel frame with vibration-isolating feet, integrated high-capacity water trap, and a complete power and hose connection kit. The Portable 12V High-Capacity Aftercooler with Water Trap provides a robust, scalable solution for operators who require dependable air quality control at higher air volumes without sacrificing mobility or operational flexibility.
