Water separator with drain (WSD) (1)
WSD's are general-purpose water separators for free water removal from compressed air.
Centrifugal force created in the cyclone throws free water (droplets) to the wall, from where it flows down to
the bottom of the bowl. The water is automatically discharged when a given level is reached. A drain valve
is provided for manual draining of the bowl.
DD filter (2)
The DD filter is a coalescing filter for general-purpose filtering, removing oil aerosols to 0.1 mg/m
and particles down to 1 micron. The filter is equipped with a drain. Typical pressure drop over filter is 0.05
bar (0.73 psi) when dry and 0.12 bar (1.74 psi) when saturated.
The air flow is from inside to outside the filter element.
PD filter (3)
The PD filter is a high efficiency coalescing filter, removing oil aerosols to 0.01 mg/m
particles down to 0.01 micron. The filter is equipped with a drain. Typical pressure drop over filter is 0.08
bar (1.16 psi) when dry and 0.2 bar (2.9 psi) when saturated.
The air flow is from inside to outside the filter element.
PDp filter (4)
The PDp is a high efficiency particle filter for dust protection, removing particles down to 0.01 micron.
Pressure drop over filter is 0.08 bar (1.16 psi) when dry.
The air flow is from outside to inside the filter element.

CD dryer

Description
The construction of the air dryer is simple, reliable and easy to service. A dryer basically consists of two
towers, containing the adsorption material (desiccant). This desiccant is a very porous grain material, able to
adsorb large amounts of water vapour.
14
The DD, PD and PDp filters are equipped with a differential pressure gauge, indicating the
pressure drop over the filter.
An electronic water drain (EWD) on WSD, DD filter and PD filter can be provided as option
(see section Optional equipment).
