FUME EXTRACTION PURIFICATION FILTER
Manufactured by Purex, Hi-tech UK, this is a professional industrial grade fume extraction and purification system.
The certificate supplied with it says that it filters to a purification level of 99.997%, with a flow rate of 130 cubic meters per hour and a velocity of 4585 meters per hour.
It has had little use and is sold in perfect working and good cosmetic condition. It has a clip on cover (not shown in the photos) that goes over the whole thing making it a very neat self contained system.
