Medical and laboratory facilities use compressed air in instruments, ventilators, dental equipment and analytical devices, where purity and reliability are non-negotiable. Contaminated air can affect patient safety or invalidate test results.
Air quality standards
Medical air must meet pharmacopoeia or local health standards for oil, water and particles, and laboratory instrument air typically requires ISO 8573-1 Class 1:2:1 or better with Class 0 oil. The dew point must be low enough to prevent any condensation in instrument lines.
Key applications
- Ventilators and respiratory equipment
- Dental handpieces and surgical tools
- Laboratory analysers and chromatography
- Pneumatic tube and sample transport systems
System design
Use oil-free compression with adsorption drying and redundant filters, and install point-of-use filtration at critical devices. Monitoring of dew point and purity is often required, and the system must be validated and documented for regulatory compliance.
