Compressed Air
Quality Monitoring &
Testing
Reliable measurement of particles, moisture and oil vapor for industrial compressed air systems.
Protect sensitive processes, check air treatment performance and plan monitoring from the compressor room to critical points of use.
Clean compressed air is critical to reliable production.
Compressed air can carry moisture, oil contamination and particles from air intake, compressors, treatment equipment and distribution networks.
Even a well-designed compressed air system requires periodic checks and appropriate monitoring. Different contaminants call for different instruments and sampling methods.
01 Solid Particles
02 Water / Dew Point
03 Oil Contamination
YUA provides instruments for these measurement areas, as well as flow and data logging equipment that complement air quality monitoring.
What can contaminate compressed air?
Four common contamination risks can harm machinery and finished products.
Moisture & Water Vapor
High pressure dew point can result in condensation, corrosion and problems in pneumatic equipment.
Oil Aerosols & Vapor
Oil contaminants can affect downstream equipment, manufacturing processes and product quality.
Dust & Solid Particles
Particles from intake air, rust and pipe scale may obstruct valves and contaminate processes.
Rust & Pipe Scale
Corroded lines and storage vessels may release debris into the compressed air distribution network.
