Dental/Medical Air

The need for a high class of air is paramount for both applications and they are only set apart with regards to their dew point value. Piston, scroll and rotary screw compressors are all utilised in this applications where CLASS 0 is the requirement option.

The Health Technical Memorandum 2022 (HTM 2022) Supplement 1

This memorandum addresses the specific requirements of systems for use in dental surgeries, clinics and hospitals. It sets out the responsibilities of managers of healthcare premises and dental surgeries needed to comply with statutory requirements and to ensure patient safety. It covers the design, installation, validation, verification, operational management and maintenance of compressed air and vacuum systems for use in dental hospitals (including university dental schools), surgeries and clinics.

Compressed Air Content

Air Compressors

Wet and lubricated air will eventually lead to damage and corrosion of instruments. Oil-free compressors offer a simple, cost effective solution to the problem of oil contamination. However, for larger installations, there are implications of higher capital costs and noise levels. Whatever compressor system is used, the importance of properly conducted regular maintenance cannot be overstressed. Filters should be changed at least annually and more frequently if recommended by the manufacturer.

Air Quality

Dental air is usually supplied via a compressor, which should be fitted with an in-take filter and a post-compression filtration and dryer system in accordance to HTM 2022. This ensures that the air is clean and dry, minimising the risk of contamination of the system by micro-organisms and improving the efficiency of dental equipment.

Dental Air - The dryer system should be capable of producing air with an atmospheric dew-point not less than -20º C (DIN ISO 8573-1 Class 3)

Medical Air - The dryer system should be capable of producing air with an atmospheric dew-point not less than -40º C (DIN ISO 8573-1 Class 2)
