The BOFA AD PVC iQ is designed to extract the harmful fumes, vapours and solid particulates generated when laser cutting or engraving PVC. One of the harmful vapours produced in this process is Hydrogen Chloride.
Hydrogen Chloride is very corrosive and highly toxic. For this reason the BOFA AD PVC iQ includes an on-board HCL Monitor – as standard. This is a vital component in ensuring that the carbon filter in the AD PVC iQ is still effective.
If this sensor fails (how ever unlikely) it will need to be replaced immediately.
