PRINCIPLES OF OPERATION
Oil-lubricated compressors create lubricant aerosols that combine with the water vapor that is present in the
compressed air. Regulations require that the condensate be separated for safe discharge into surface water,
sanitary sewers and wastewater treatment plants.
ZEKS OS Series Oil/Water Separators collect discharged condensate from the compressed air system.
Condensate enters the unit through the inlet ports and flows through the depressurization chamber where any
air that accompanied the condensate is separated and released to atmosphere. Condensate enters the
Absorption Tower (Tower #1) where the oil is absorbed by the element. The remaining condensate enters the
Carbon Finishing Tower (Tower #2) where any remaining oil residue. Condensate is then released to the
drainage system.

INSTALLATION AND INITIAL START UP
7.1 UNPACKAGING AND LOCATION SELECTION
Open the packaging for the OS Series Oil/Water Separator and remove the lids from Tower #1 and Tower #2.
Using normal lifting precautions, remove the Absorption Element (large white element) from Tower #1 and the
Carbon Finishing Element from Tower #2. Place lids and elements aside. The OS Series Oil/Water Separators
are designed to easily fit against a wall or in a corner. Select a location where both the condensate drain lines
from the compressed air system and the OS Oil/Water Separator Drain outlet can be conveniently installed
without the possibility of becoming damaged or kinked. Position the unit with the TEST port to the front.
Connect the provided TEST Valve and outlet nipple to the appropriate ports as indicated on the OS
Series unit. Do not over-tighten connections.
7.2 CONNECTION AND ASSEMBLY
Connect the condensate lines to the 1/2” inlet(s) located on top of the unit. Screw plugs (not provided) should
be used to seal the inlet ports that are not going to be utilized.
Connect the 1/2” drain outlet connection to a suitable drain. The drain line needs to be installed without obstruc-
tion and in a manner that will allow for unpressurized condensate flow. Testing shows that lubricant carryover in
the separated drain water is less than 10ppm or lower. Check local codes for applicable drainage requirements.
Install the Carbon Finishing Element in to Tower #2. Push the element to the bottom of the vessel and confirm
that the outlet drain port is not obstructed.
Confirm that there is no harmful pressure in the condensate lines from the compressed air system.
WARNING

If time permits, the Carbon Finishing Element should be allowed to soak in water for a period of 24
hours prior to installation. Though not necessary, soaking of the Carbon Finishing Element will pre-
vent carbon dusting from occurring within Tower #2 of the unit. Carbon dusting is completely harm-
less to the OS Series Oil/Water Separator and drainage systems.
N O T I C E
Normal lifting precautions need to be observed when servicing the ZEKS OS Series Oil/Water
Separators. Failure to observe lifting precautions may result in personal injury. Elements will be sat-
urated with oil and condensate and therefore will be heavy. Protective clothing and gloves should
always be worn when servicing the units.
