Altec AIR HR3 Heatless Desiccant Air Dryer – 9 SCFM

Product Description

The Altec AIR HR3 Heatless Desiccant Air Dryer provides dependable ultra-dry compressed air for systems up to 9 SCFM, making it an excellent solution for small compressed air systems and point-of-use drying applications where moisture control is essential. Built with a twin-tower heatless regenerative desiccant design, the HR3 continuously removes moisture from compressed air while regenerating the desiccant in the alternate tower, ensuring a steady supply of clean, dry compressed air.

With a standard -40°F pressure dew point, the HR3 protects pneumatic tools, instrumentation, spray equipment, and sensitive processes from moisture contamination that can lead to corrosion, freezing, and costly equipment damage. Its compact footprint makes it ideal for installation in small compressor packages, mechanical rooms, or directly at the point of use where dry air is critical.

Engineered for reliability, the HR3 features spring-loaded desiccant beds that help extend desiccant life, while the fully re-pressurizing tower design maintains stable outlet pressure and airflow during switching cycles. The unit also includes a NEMA 4X electrical rating, allowing it to perform reliably in demanding industrial environments.

The HR3 is available in 115 Volt / 1 Phase or 230 Volt / 1 Phase configurations and can be equipped with optional moisture indicator and tower pressure gauges, giving operators clear visibility into dryer performance and system operation.
