Duplex filters offer 2 stage filtration within one filter unit. Each filtration packege provides an XA grade element in thme lower section for oil removal, while the AC grade element in the upper section is for odour removal.2
Direction of air flow is inside to out through XA grade and outside to in through AC grade filter element.3
ADV6000C drains are fitted to models D3028XAC to D3058, ADV6000 drains are fitted to models D3059XAC to D3109 4 Models D3059 XAC to D3109 XAC can be adapted to use ¼" drains with a reducer.4

Activated carbon filters must not operate in oil saturated condutions and will not remove certain types of gases including carbon monoxide (CO) and carbon dioxide (CO2).6
Duplex filters are manufactured from cast aluminium alloy and are PED 97/23/EC compliant for group 2 gases.7
Threaded connections are Rp (BSP parallel) to ISO 7/1 or NPT to ANSI B2.1 if supplied within North America.8
For NPT connections are Rp (BSP parallel) to ISO 7/1 or NPT to ANSI B2.1 if supplied within North America.9
Filter elements should be changed every 12 months / 8000 hours (whichever comes first). Activated carbon filter elements should be changed every 6 months / 1000 hours (whichever cones first)10
Filters are suitable for use with mineral and synthetic oils plus oil-free compressed air applications.11
Silicone free options are available, please contact Sales for details.
