Frequently Asked Questions

Why Do I Need An Oil Free Compressor?

Best practice demands that air used in a dental surgery is free from contaminants, such as oil, water and particulate which may be harmful to the patient and can compromise clinical performance. Poor quality air is also very damaging to hand-pieces and ultrasonic equipment.

What Does The Dryer Do?

All compressors produce water as part of the mechanical process of drawing in atmospheric air and compressing it to high pressure. Moisture laden air enters the dryer passing into a bulk water pre-separation unit. Secondary drying occurs as the air passes through absorbent desiccant crystals. After each completed cycle the dryer purges and the crystals are regenerated. Clean, dry air is then stored in the receiver ready for use.

Do I Need Additional Filtration?

As all DenComp compressors already supply oil free, clean dry air the only additional filtration suggested is the installation of a Duplex Breathing Air Filter to comply with the requirements of European Air Quality Standard ISO 8573-1:2001 (E). The OF series may require supplementary filtration dependent on application. We can offer advice on this.

Do I Need To Comply With HTM2022?

HTM2022 is the Health Technical Memorandum that sets out standards for compressed air in Health Authority premises. HTM2022 Supplement 1 refers specifically to Dental Compressed Air. Private practices are not required to conform to this but very good guidance is given as to what quality of air should be delivered into the surgery. We would be very happy to discuss this with you further.

Do I Have To Do Any Of My Own Maintenance?

Dental practices have historically been reluctant to carry out day to day maintenance either because the location of the compressor might be awkward to get to or because it's dirty and unpleasant to work on. DenComp compressors only require that the practice switches the compressor on in the morning and off at night. Routinely the practice should not need to do anything further other than monitor the water level in the drain bottle and empty if required.

Do I Need To Have The Compressor Serviced?

Yes. A compressor is a mechanical device and should be serviced annually to ensure correct and efficient running. Additionally practices are regularly inspected and showing that you have the compressor maintained is normally a requirement. Breathing Air Filter elements should be replaced at least annually.

Does The Pressure Vessel Have To Be Inspected or Certificated?

Yes. A practice must have a Written Scheme Of Examination. This details the compressed air equipment on site with ancillary pipework, regulators and filters and sets a periodicity of examination. It is a legal obligation that the air receiver is tested in accordance with the scheme. This is the responsibility of the practice to ensure this is done.
