The DA series modular desiccant dryer of the SR brand is a domestic modular pressure swing adsorption dryer launched by SR Filtration. Installed in the air compressor system, it is used to dry compressed air. It can reduce the pressure dew point to -70°C, with standard dew points at -40°C and -20°C, and -70°C as an optional dew point.

The DA series modular desiccant dryer utilizes the principle of pressure swing adsorption. It always keeps one chamber filled with adsorbent online for drying and another chamber filled with adsorbent for regeneration. When the switching criteria are met, it automatically switches the working states of the chambers. During this period, the chambers change the internal pressure through the opening and closing of valves to achieve the optimal water removal capacity.

The DA series modular desiccant dryer has undergone 100% leak testing, 100% function testing and 100% performance testing before leaving the factory. It operates reliably in accordance with ISO8573:1-2010 standard and provides users with high-quality compressed air. The DA series modular desiccant dryer is designed specifically for air compressor rooms, on-site application points, or integration into original equipment. It is the most reliable among similar products and provides an effective solution for compressed air drying.
