Rotary Unions for Air

Deublin's unique tandem rotary union is a combination of two unions to prevent cross-contamination with independent sealing in each. This rotating union is suitable for several different media combinations that include air.

The Deu-plex air rotary union is designed with two 1/4" channels for low-speed applications.

Deublin's 3/8" rotary union is ideal for small air applications. The compact design features seal material to enhance the union's service life and an oiler for relubrication.

Designed with four independent passages, Deublin's 1379 rotary union operates with various types of media such as air. A vent in between passages eliminates cross-contamination of two types of media. The four passage rotary union is best for applications like clamping and unclamping.

Deublin's 1479 rotary union operates at a higher flow rate with various types of media such as air. The design features widely spaced ball bearings to absorb the large side loads and reduce wear. Some applications requiring four passages are work piece or spindle cooling.

Deublin 1/2" two-channel unions for pneumatic applications allow for alternating pressure.

The best solution for low speed, air rotary union is Deublin's 17 series. The 17 series offers specially designed seals and compounded O-rings to ensure a longer life. An economical solution ensuring the rotating union's durability and efficiency.

Low-speed rotary unions require special sealing with compounded O-Rings for longer seal life in pneumatic applications.

Deublin's high pressure and high-speed AP rotary union features balanced mechanical seals made with tungsten carbide for smooth rotation and seal wear resistance.

The D series is a high-pressure swivel with the ability to handle angular movement. Power-steering systems often use Deublin's D series in Earthmoving equipment.

Deublin's self-supported rotary union can be utilized for a variety of air-hydraulic applications and designed with balanced mechanical seals reducing seal wear.

The Deublin 1102 air rotating union for air is compact but built for durability in applications like small air clutches. Seals are carbon graphite to tool steel and have an oil port for re-lubrication for pneumatic applications.

Deublin's 3/8" rotary union is ideal for small air applications. The compact design features seal material to enhance the union's service life and an oiler for relubrication.

The 1/2" Deublin rotary union is a self-supported, monoflow design. The 1205 features lubricated for life bearings for longer life, reducing downtime and maintenance for rotary union air applications.

Deublin designs unions to handle any pneumatic applications that require continuous high speeds or high pressure.

Deublin's single passage rotary union is designed to transfer large volumes of air. The 3/4" design features balanced mechanical seals to extend the life of the union and reduce unwanted maintenance.

Large volumes of media, such as air, are transferred to a stationary source through Deublin Rotary Unions.

Deublin's compact pneumatic design can configured to fit your custom application.

Monoflow Rotary Unions with more than twice the flow capacity of 1/4" pneumatic and hydraulic unions.

Deublin's Deu-plex rotating union is a precision solution ideal for pneumatic clutch and brake applications. The two-passage design should only be used with the same media as this will extend the seal life.

Best suited for air clutches, the Deublin Deu-plex air rotary union was designed for continuous operation. Seals are carbon graphite to ceramic to ensure long service life.

To prevent contamination amongst media, like air, Deublin's two-channel union features independent passages with balanced mechanical seals. The seals allow for maximum operation and an increase in life span.

Deublin's Dual-passage rotary union is custom for pneumatic, around-the-shaft applications.
