Filter Cartridge Description
General purpose applications such as plant compressed air:
Single stage filtration. Use a Grade DX filter cartridge
Instrument air and other critical air requirements
Two stage filtration is necessary. Use a Grade DX followed by a Grade BX filter cartridge.
As a general rule, a Grade BX filter cartridge should not be used alone.
For rare instances where even a trace amount of oil vapor can cause a problem, three stage filtration is necessary. Use a Grade DX followed by a Grade BX, and a type CI cartridge.
