2.0 Description
2.1 Operating Elements and Construction
2.2 Theory of Operation
The efficient removal of hazardous fumes at your workplace is a two-step
process: fume capture and filtration. The filter unit is supplied with a set of
filters already installed.
To capture the fumes, OK International recommends use of optional exhaust
arms and accessories (purchased separately). The exhaust arms need to be
set up properly (instructions supplied with exhaust arms) and the nozzle
positioned in a way to optimize fume capture.
Air extracted from your work area will be purified when passing through the
filters inside the unit and is then returned into your work area.
Should the filters become blocked an alarm will start to sound. See section 5.4
for filter replacement procedures.
Contact your local OK International representative if there are any questions
regarding the proper selection of filters for your application.
