Key role of hospital compressed air system
hospital compressed air system is an indispensable infrastructure of modern medical institutions, providing clean, dry, oil-free and constant pressure Medical Air for operating rooms, ICU, respiratory therapy, anesthesia equipment and dental units. The system must conformGB 50751 -2012 technical specification for medical gas engineeringmandatory standards to ensure that the gas supply quality meets clinical safety requirements.
Differential application of medical air compressor and dental air compressor
- medical air compressor: dedicated to the central gas supply system, the output pressure is usually 0. 5–0.7 MPa, after multi-level filtration, drying and precision sterilization, it meets ISO 8573-1 Class 1: 2:1 (particle, water, oil) grade;
- dental air compressor: most of them are small oil-free silent models, which directly drive scaler, light curing lamps and pneumatic mobile phones. Refrigerated air dryer and adsorption oil remover must be configured independently to avoid the risk of oral cross infection.
Compliance and system design essentials
according to GB 50751, the hospital compressed air system must realize dual-circuit redundant gas supply, real-time pressure/dew point/oil mist online monitoring, and be equipped with standby units and emergency switching devices. All pipes shall be made of 316L stainless steel, and the welding process shall conform to ASME B31.9 standard to prevent the risk of microbial breeding and metal precipitation.
