Hangyang labyrinth compressors
Non-contact compression for high-purity gas service
Standard- and high-pressure labyrinth compressor packages for oxygen, carbon dioxide, nitrogen, argon and natural gas applications, with capacities up to 40,000 Nm³/h.
Labyrinth compressor range
Two configurations, one proven non-contact platform.
Hangyang labyrinth compressors are available in standard-pressure external-compression and high-pressure internal-compression configurations. The platform is designed for gases where purity, seal reliability and low-maintenance operation matter.
Industrial gas production, CO2 compression, oxygen and nitrogen service, argon duty, natural gas and applications with dry, wet, dirty, reactive, corrosive or toxic gases.
External-compression model
Standard pressure
- Capacity
- 1,000-8,000 Nm³/h
- Inlet pressure
- 10-15 kPa
- Discharge pressure
- 2-3 MPa
Optimized for low-pressure inlet conditions.
Internal-compression model
High pressure
- Capacity
- Up to 40,000 Nm³/h
- Inlet pressure
- 0.8-1.0 MPa
- Discharge pressure
- ≤7.0 MPa
Higher throughput for pressurized inlet conditions.
Project references
Workshop and skid-mounted configurations.
Packages can be engineered around the compressor body, process piping, separators, instruments, controls and skid structure needed for the duty. Export contracts have been signed for Southeast Asia and Europe, with a China reference in continuous operation for six years.

How the labyrinth seal works
Pressure control without sliding contact.
Labyrinth clearances control pressure by repeated throttling and expansion cavities between the cylinder wall and the piston skirt. Gas accelerates through each narrow clearance, velocity dissipates in each cavity, and pressure falls progressively along the seal.
Throttle
Gas accelerates through each narrow clearance.
Expand
Velocity is dissipated inside each cavity.
Repeat
Pressure falls progressively along the seal.
Result: controlled leakage with zero sliding contact.
Labyrinth vs contact-seal technology
Contactless labyrinth sealing removes the wear mechanism.
Compared with piston rings and packing, labyrinth clearances control pressure without rubbing contact. This is the core difference behind the maintenance, purity and reliability advantages.
Key advantages
Higher reliability, lower maintenance and lower energy cost.
For suitable duties, the non-contact sealing arrangement supports higher reliability, lower maintenance costs with an MTBM of 2 years, and 3-5% less energy cost than similar compressors.
Higher reliability
Non-contact labyrinth sealing removes the sliding wear mechanism found in rings and packing.
Lower maintenance costs
Designed around an MTBM of 2 years, with no piston-ring replacement cycle for the labyrinth sealing element.
3-5% less energy cost
Supports 3-5% less energy cost than similar compressor designs on suitable duties.
Gas media
Configured for the gas and the compression duty.
Final compressor selection depends on gas composition, inlet condition, required discharge pressure, capacity, materials, sealing philosophy, utilities and control requirements.
