  • Oil-Free Compression:

    • Oil-free gas compression ensures that no oil is introduced into the compressed gas stream. This is essential for applications where contamination could be harmful, such as in toxic and corrosive applications. The compressor ensures clean gas compression, preventing any oil carryover or contamination.

  • Three Sets of V-Ring Packing:

    • The T-Style compressor features three sets of V-ring packing per piston rod. This configuration provides a high level of sealing performance, effectively controlling leakage and minimizing any risk of contamination in sensitive processes.

  • Two Distance Pieces:

    • Two distance pieces are included in the design to further enhance leakage control. These pieces help ensure that any gas leakage is effectively contained, which is critical when working with toxic or hazardous gases.

  • Purge Kits for Distance Pieces:

    • Purge kits, including all necessary accessories to purge or pad each distance piece, are available as an option. These kits help maintain maximum leakage control by allowing the user to purge the distance pieces, ensuring clean and efficient operation.

  • Adjustable Packing Screw:

    • The adjustable packing screw on the lower packing allows for fine-tuning the seal to maximize performance over the life of the packing. As the packing wears over time, users can adjust the screw to maintain effective sealing, extending the lifespan of the compressor and ensuring ongoing performance.

  • Maximum Leakage Control:

    • The combination of the three sets of V-ring packing and two distance pieces ensures that the T-Style compressor provides maximum leakage containment. This is critical when working with sensitive gases, ensuring that there is no escape or contamination in the environment.

  • Designed for Toxic and Corrosive Applications:

    • This compressor is typically used in toxic and corrosive applications, where the integrity of the compressed gas must be maintained. The oil-free design and advanced sealing mechanisms make it ideal for environments where oil-free gas and maximum leakage containment are critical.

 

Piston displacement: up to 117 cfm (198.8 m3/hr)
Working pressure: up to 1,200 psi (82.8 bar g)
Brake horsepowers: up to 45 hp (34 kW)
Maximum outlet temperature: 350°F (177°C)

 

  • Oil-Free Gas Compression:

    • The T-Style compressors are designed for oil-free gas compression, which ensures that no oil is introduced into the compressed gas stream. This is ideal for applications where maintaining gas purity is critical, such as in chemical, pharmaceutical, and food processing industries.

  • Three Sets of Packing per Piston Rod:

    • Each piston rod is equipped with three sets of packing, ensuring excellent sealing performance and minimizing the possibility of leakage. This multi-layer packing configuration enhances the longevity and reliability of the compressor.

  • V-Ring Packing Sets:

    • The V-ring packing sets consist of several V-rings, male and female packing rings, washers, and a spring, all working together to provide a strong seal. This packing system is designed for durability and maximum leakage control.
    • Exception: Models T791 and T891 utilize a combination of V-ring and segmented packing, which provides additional sealing capabilities for specific applications.

  • Cylinder Sizes:

    • The compressors are available in a wide range of cylinder sizes to accommodate different compression needs:
      • 1.25″, 1.75″, 2.5″, 2.75″, 3.0″, 3.25″, 4.0″, 4.5″, and 6.0″.
    • This variety allows for tailored solutions depending on the required flow rate and pressure conditions.

  • Single and Two-Stage Designs:

    • The compressors are available in both single-stage and two-stage designs, offering flexibility depending on the application. The two-stage design is ideal for achieving higher pressures and balancing load distribution across stages.

  • Distance Pieces:

    • Constructed with two distance pieces, the compressor design enhances leakage control and prevents contamination of the gas. These distance pieces can also be purged to maintain sealing performance over time.

  • Connection Options:

    • The compressors offer a variety of connection types to ensure compatibility with different systems:
      • NPT connections (National Pipe Thread),
      • Class 300 RF flanges,
      • DIN flanges (for European standards).
    • This flexibility allows the compressors to integrate seamlessly into different piping configurations.

  • Water Cooled Option:

    • Some models of the T-Style compressors offer a water-cooled option, which is ideal for applications where heat dissipation is critical. Water cooling helps maintain optimal operating temperatures and prevents overheating, especially in high-pressure operations.

  • Double-Acting Designs (T791 and T891 Models):

    • Models T791 and T891 are available in double-acting designs, where gas is compressed on both the forward and return strokes. This design provides higher efficiency, as both directions of piston movement contribute to the compression process, making it suitable for applications that demand higher output.
