Designed for systems up to 10 CFM (3 HP), this wall-mounted dryer delivers dew points as low as –80°F and relative humidity down to 0.01% RH, protecting your tools, paint finishes, and pneumatic equipment from moisture and contaminants.

Each system includes two-stage pre-filtration, molecular sieve desiccant towers, automatic drains, purge exhaust mufflers, and a solenoid valve timer for reliable, low-maintenance operation. With average annual maintenance under $100, the Pure Series delivers unbeatable performance and value for shops and industrial environments alike.

Available Variants
