Contaminants frequently present in compressed air often threaten the well being of breathing air. These can include;
- Fumes
- Oil
- Vapours
- Gases
- Solid Particles
- Micro-organisms
It is a legal requirement and an employer’s clear responsibility under the requirements of the HSE to ensure that the quality of air supplied to Respiratory Protective Equipment (RPE) is at a suitable standard. In accordance with COSHH Regulations compressed air supplied to breathing apparatus “should be tested at least once every 3 months and more frequently when the quality of the air cannot be assured”. Testing must not only be completed but must also be documented with records being maintained for minimum period of 5 years.
Air Dryer Technology Limited has the equipment and expertise to provide an accurate on-site air quality testing service. The service provides regular inspection and maintenance of compressed air breathing air purification equipment and air analysis of the basic COSHH contaminants. Calibrated portable equipment utilising chemical reagent colour change tubes is used to determine satisfactory saturation levels of Oxygen, Carbon Monoxide, Carbon Dioxide and Oil. Water vapour is measured by using a portable dewpoint meter.
Air quality and dewpoint measurement on compressed air and instrument air systems can also be provided to determine the condition of currently installed compressed air treatment equipment. Single daily checks or a longer data logging service are available.
Air Dryer Technology Limited can supply a complete range of breathing air purifiers designed to match the specific needs inherent when breathing from a compressed air supply. Many applications exist, from the life threatening environments of fire fighting, hazardous shot blasting and paint spraying operations, to critical medical and hospital air requirements. Typical applications are;
- Shot Blasting
- Tank Cleaning
- Tunnelling
- Pharmaceutical Manufacturing
- Spray Painting
- Medical and Hospital Air
- Offshore/Marine
- Asbestos Removal
