Air Dryers

NW Series Heatless Air Dryers

Northwest Equipment Heatless Air Dryers provide clean, dry compressed air resulting in improved air system operation and unparalleled reliability.

The NW series is the result of our many years of experience providing quality compressed air to our oil and gas partners and is a product specifically designed for instrumentation and utility process requirements.

The rugged design provides standard features that are either not available on competitive units or require custom modification that prove unreliable and difficult to service as equipment ages.

Our robust, yet simple package will result in years of trouble-free service. Maintenance requirements and down time have been greatly reduced making the NW the most reliable dryer available today.
