Inlet/ outlet for air

1. Inlet for the damp air

Check that air entering the air drying unit does not exceed the maximum

temperature for the drying unit in question.

This is important since the performance of the air drying unit depends on the

temperature of the inlet air.
If necessary it is recommended that a cooling radiator is installed before the air

drying unit.

2. Outlet for the dry air

There are manifolds (

) at the inlet and outlet to allow the connection of several

users to the air drying unit.
