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

Oxygen	20.9 ± 1.0%
Nitrogen	78.0% by inference
Carbon dioxide content of medical air	< 500 ppm v/v
Carbon monoxide content	< 5 ppm v/v
Oil content	< 0.5 mg/m3
Water content	dew point of -20º C atmospheric pressure
Particulate content	Free from visible particles in a 75 litre sample
Sulphur dioxide	< 1 ppm v/v
Nitric oxide + nitrogen dioxide	< 2 ppm

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)

Product Overview - Piston Technology

The comprehensive range of oil free compressors which are extremely robust, efficient and are designed for demanding applications. All of our oil free piston compressors (plus dryer and bacteriological filter) conform to 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. The vast range incorporates:

All models utilise an innovative pump of very efficient construction, producing higher air output with a maximum air pressure of 10 bar. The pump design allows a lower running speed to be used, leading to reduced noise levels and longer life. Special anti-vibration mounting are also fitted as standard, reducing pump vibration and cabinet noise further.

The models in this range which use an integral membrane dryer offer a major operational advantage in that they are practically maintenance free. The receiver is also coated internally to avoid any contamination of the compressed air.
