Short Description
High‑capacity commercial refrigerated air dryer designed for dependable moisture removal in very high‑flow compressed air systems up to 251 CFM.
Full Description
The SMC IDFB70‑23N Commercial Refrigerated Air Dryer is engineered for heavy‑duty industrial compressed air applications where large airflow capacity and consistent moisture control are essential. With an airflow capacity of 166–251 CFM, this model is ideally suited for 30–40 HP air compressors, making it a reliable solution for large production facilities, processing plants, and centralized compressed air systems.
Using advanced refrigerated air drying technology, the IDFB70‑23N cools incoming compressed air to condense water vapor, which is then efficiently separated and discharged through an integrated high‑capacity automatic condensate drain system. Under rated operating conditions, the dryer maintains a stable outlet pressure dew point of approximately 50°F (10°C), helping to prevent corrosion, water carryover, and moisture‑related damage to downstream piping, pneumatic tools, and automation equipment.
The unit features an air‑cooled condenser, robust industrial enclosure, and service‑friendly internal layout designed for ease of installation and maintenance. Built for continuous indoor operation, the IDFB70‑23N delivers dependable performance, energy‑efficient operation, and long service life in demanding industrial environments.
