Water/Oil Separator

Water/oil separators for separating condensate are typically recommended to comply with environmental requirements. Water/oil separators are a simple device that separate the water from the oil by allowing stratification to occur over time. Since the specific gravity of oil is lower than water, it coalesces at the top of the unit while the water settles in the bottom of the tank. A filter media is installed in the unit that prevents the oil from migrating to the lower level of the tank. The water portion of condensate is then drained off the unit into the storm or sanitary sewer. The oil eventually saturates the filter media and is disposed of as non-hazardous


Non-treatment of compressed air condensate leads to high legal and financial risks, and as off-site disposal cost continue to increase, your profits will continue to decrease. Furthermore, traditional, gravity type water/oil separators lack the ability to adapt both to new lubricants and new growth, while often times requiring time consuming adjustments from staff that is usually unavailable. 

How it Works

  1. The oil containing condensate first flows under pressure into the pressure relief chamber.

  2. In the pressure relief chamber, the pressure is reduced without causing turbulence in the downstream separation tank for the separation of free oils.

  3. Any entrained coarse dirt particles are retained in a removable receiver. 

  4. The condensate then flows through the oleophilic pre-filter which boasts a large active filtering surface. With a flow from the inside to the outside, it binds the remaining oil droplets and also absorbs any residual floating oil in the filter chamber.

  5. At the core is the OEKOSORB primary filter with cartridge technology. Here, residual oil fraction are reliably retained. What remains is water which may be directly introduced to the sewer system.
