• Exteranal Carbon Filter is easily changed without entering unit
• Tough, impact-resistant, high density polypropylene construction
• Two coalescing packs for extra filtration and longer lasting carbon filter

Exceeds Most Environmental Standards

While some states push for even lower restrictions, for most states, 50 ppm is currently the standard concentration of oil allowed in water destined for sanitary sewers. Envirosep Plus oil water separator units, with their unique separation design and activated filter, have achieved water effluents containing less than 15 ppm of oil in most compressor oils and 50 ppm or less with polyglycols.

Three Phase Separation

Here's how the Envirosep Plus oil water separator combines three different separation methods for superior results:

• Oily condensate enters the unique Expansion Chamber which allows air from automatic drains and ball valves, in blasts of five (5) seconds or less, to exit safely and the condensate to gravity flow into the unit.

1. Two large, turbulence-free Separation Chambers provide sufficient residence time for gravity to effect the separation process. The condensate enters the first chamber, the effluent is forced to go through the coalescing filter pack where oil is coalesced and separated from the clean water. Clean water from the bottom chamber is gravity fed to the second chamber for duplication of the first chamber.
2. A second stage of gravity oil water separation, plus coalescing polypropylene barrels, provides greater turbulence-free residence time for further separation
3. A large volume, Exteranl Activated Carbon Filter polishing unit provides clean, sheen-free water

As indicated above, coalescing, gravity oil water separation and carbon absorption are the three separation methods used by the Envirosep Plus.

Some lubricants such as polyglycols and phosphate esters have specific gravity equal to or greater than water. Because of this higher specific gravity, special equipment is required to effect separation of these fluids from water. In addition, lubricants which are miscible with water, (polyglycols) or contain additives (ATFs), such as detergents, which cause the lubricant to form stable emulsions with water, cannot be separated using ordinary gravity separation devices. The Envirosep Plus oil water separator is not an ordinary device, and tests have shown the Envirosep Plus oil water separator to deliver 50 ppms or less with polyglycols.

Envirosep Plus oil water separator utilizes a patented External Activated Carbon Filter polishing unit to facilitate easy filter change without having to enter the unit and create internal turbulence. The external filter simplifies the problems associated with handling the spent carbon filter. Depending on a number of vairables (the most significant being the type of lubricant in use), a carbon filter will normally last from nine to twelve months, (six to nine months with polyglycols).

Choosing the correct size unit

Four key factors must be evaluated when selecting the size of the Oil Water Separator unit to best fit your needs:

1. Compressor capacity, SCFM
2. Base stock of oil
3. ISO grade of oil
4. Additives present in the oil

To properly size the Oil Water Separator unit for each application requires careful consideration of these variables. Use of the oil water separator sizing charts make this decision quick and easy.

Remember, oily condensate can originate from a number of locations in the air compressor system: compressor inter-cooler, after-cooler, separators, receivers, dryers and filters. For greater efficiency and additional savings, they can all be piped together before connecting the oil water separator plus unit.
