Aircel VF Series Non-Cycling
Refrigerated Air Dryer

10 – 2,000 scfm
The Aircel VF Series (10 - 2,000 scfm) offers the highest efficiencies at varying flow conditions in a lightweight, compact design. No other dryer in the industry can offer the efficiency ratings achieved by the VF Series dryers in variable flow operation. VF Series dryers are built with the Variable Flow heat exchanger, which allows for desired dew point performance regardless of flow variations. Typically, other dryers with mechanical moisture separators lose performance as compressed airflow velocity increases or decreases substantially around the nominal design point.

• ISO 8573.1 Class 4 (38°F/3°C) dew point performance.
• Single point air in/out and electrical connections.
• Three step process thoroughly removes condensed moisture from the chilled, compressed air. This process provides separation efficiency in excess of 98% throughout the entire range.
• Ambient Air Temperature: 35°F – 120°F
• Maximum Inlet Air Temperature: 140°F
• Maximum Operating Pressure: 200 psig


The VF Series high efficiency heat exchanger utilizes a three-step process to thoroughly remove condensed moisture from the chilled, compressed air. This process provides separation efficiency in excess of 99% throughout the entire flow range. Our VF non-cycling range is focused on reliable, constant dew point performance in all flow conditions.

With its excellent heat transfer coefficients and low-pressure drop, these dryers will outperform the competition in protecting your compressed air system, machinery, and tools; and will improve your manufacturing processes.

How It Works

• Saturated, compressed air enters the system and moves into the pre-cooler/re-heater (A), where it is pre-cooled by the cold outgoing air.
• The air is then directed through the air-to-refrigerant heat exchanger (B), where it is cooled to 38°F by the refrigeration system.
• The cold, saturated air flows into the three-stage separator (C), where liquids are removed from the air. This separated condensate is then ejected from the system via the Aircel condensate drain (D).
• The cold, dry air is then reheated by the incoming warm air (E) before leaving the dryer.
