In applications where three monthly tests are carried out, failed tests indicate that any compressed air produced since the last known good test is in question. This means that three months of the compressors output is of questionable quality.
The ACG+ can continuously monitor the output from your breathing air compressor for carbon dioxide, carbon monoxide, moisture, oxygen and volatile organic compound content. This information provides a good indicator of compressor health and an early warning of compressor serviceability issues -empowering you to plan preventative maintenance before the quality of the compressed air becomes a risk to users.
Analox's recommendation is that continual monitoring is preferable to taking a “snap shot” of the air quality.
