Nano DXR 0400 NA Refrigerated Air Dryer - 400 SCFM

Nano DXR 0400 NA Refrigerated Compressed Air Dryer

Moisture is one of the most common causes of corrosion, equipment wear, and product contamination in compressed air systems. The Nano DXR 0400 NA refrigerated compressed air dryer is designed to remove that moisture before it reaches your downstream equipment, helping maintain reliable operation while reducing maintenance costs and unplanned downtime.

Designed for compressed air systems up to 400 SCFM with 2" (F) NPT connections, the DXR 0400 NA combines dependable direct expansion refrigeration with a compact footprint, making it an excellent choice for small to medium industrial applications. Whether you're protecting air tools, CNC equipment, pneumatic controls, or production machinery, this dryer helps deliver the clean, dry air your operation depends on.

How It Works

The DXR 0400 NA uses a direct expansion refrigeration system to cool incoming compressed air below its saturation point. As the air temperature drops, water vapor condenses into liquid, is separated from the air stream by the integrated moisture separator, and is automatically discharged through the zero-air-loss electronic condensate drain. A combined air-to-air and air-to-refrigerant aluminium block heat exchanger pre-cools the incoming air while re-heating the outgoing air, improving efficiency and preventing pipe sweating downstream.

Common Applications

The Nano DXR 0400 NA is well suited for manufacturing facilities, automotive and maintenance shops, machine shops, packaging equipment, CNC machinery, paint systems, laboratories, and general industrial compressed air systems. It provides reliable moisture removal wherever clean, dry compressed air is required to protect equipment and maintain product quality.

Installation & Maintenance

For best performance, install the dryer downstream of an aftercooler and moisture separator, and upstream of your compressed air filtration system. Periodically inspect the condenser for dust buildup and verify the automatic condensate drain is operating properly to maintain peak efficiency and dependable pressure dew point performance.

Why Choose the Nano DXR 0400 NA?

A quality refrigerated air dryer is one of the best investments you can make in a compressed air system. By removing moisture before it reaches your equipment, the Nano DXR 0400 NA helps extend component life, reduce maintenance costs, improve product quality, and increase overall system reliability. Its compact design, energy-efficient operation, and proven performance make it an excellent choice for facilities that depend on clean, dry compressed air every day.

Recommended Filtration

Compressed-air filtration protects your Nano DXR 0400 dryer and improves downstream air quality. The DXR 0400 includes an integrated water separator, so it handles bulk water on its own — these filters address particulate, oil aerosols, and vapor. As a general guide, pair the dryer with Nano GFN 0450 filtration (rated 450 SCFM to match its flow):

• ■ Pre-filter (before the dryer) — Nano GFN 0450, Grade M1 (1 micron), to remove particulate and coarse liquid. Recommended as standard protection.
• ■ After-filter (after the dryer) — Nano GFN 0450, Grade M01 (0.01 micron), for high-efficiency coalescing of fine oil aerosols.
• ■ Optional carbon filter — Nano GFN 0450, Grade AC (activated carbon), where oil-free, odor-free air is required.

Filter sizes shown are a general guide based on airflow. For your exact operating pressure and temperature, contact us to confirm sizing. Nano offers a 2-year dryer warranty when pre-filtration and non-corrosive piping are installed.
