Product Overview

The Dry Unit Series is a precision air drying solution designed to deliver dry, filtered compressed air directly from the source. Integrated with an Air Filter, Mist Filter, or Micromist Filter, and a Regulator, this unit ensures consistent performance by removing moisture and particulates while maintaining stable pressure output. Its compact design enables direct connection to the air source, making it ideal for space-constrained industrial environments where efficiency and simplicity are critical.

Construction and Materials

The Dry Unit Series is constructed using durable materials suitable for continuous operation in demanding conditions. The unit features a robust housing that supports internal filtration stages including an Air Filter, Mist Filter, or Micromist Filter, along with a built-in pressure regulator. All components are designed to handle non-corrosive and non-flammable gases, ensuring compatibility across a wide range of industrial applications.

Configuration and Connections

The unit is configured for direct connection to the compressed air source via Rc1/4 or Rc3/8 port sizes, enabling seamless integration into existing systems without requiring additional piping or intermediate equipment. This direct linkage simplifies installation and reduces system footprint, making it particularly effective in environments where space efficiency and streamlined operation are essential.

Operating Characteristics

The Dry Unit Series operates within a pressure range of 0.05 to 0.85MPa for the internal hollow fiber membrane (with external pressure at 0 to 0.05MPa), and is rated for maximum operating pressure of 1.0MPa. The unit can function across an ambient temperature range of 0 to 50℃ during operation, with storage conditions extending from -10 to 60℃. Operating temperatures for the fluid medium are maintained between 0 and 55℃ (no freezing), and the pressure setting range is set from 0.05 to 0.85MPa.

Sizes and Options

Available in standard configurations with Rc1/4 or Rc3/8 port sizes, the Dry Unit Series offers flexibility in integration across different equipment types. While color options are not specified, the unit is available in standard industrial finishes suitable for both indoor and outdoor use. Variants are designed to accommodate different filtration stages—Air Filter, Mist Filter, or Micromist Filter—depending on application requirements.

Installation and Integration

The Dry Unit Series includes a switch output with NPN or PNP open collector configuration, capable of driving up to 125mA load current. This feature enables direct integration into control systems for pressure monitoring and automated shutdown functions. The unit also features a digital pressure display with an indication range from -0.100 to 1.000MPa (at 2Hz update frequency), providing real-time feedback on system status, and is rated for proof pressure up to 1.5MPa.
