Description
KSI KONTREC KON-S450 450 CFM Oil-Water Separator
Reliable compressed-air condensate treatment without activated carbon. The KSI Technologies KONTREC S450 helps separate compressor lubricant from water generated by compressed-air systems, using polypropylene filtration and coalescing media. Rated for up to 450 CFM compressor capacity, this compact oil-water separator offers serviceable media and a choice of standard and K-type treatment.
Choose the correct version: Standard KON-S450 is for mineral-oil-based compressor lubricants. K-type KON-S450-K is designed for synthetic lubricants and stable emulsions. Both options are available on this product page.
Features and Benefits
- Two-stage oil separation: Polypropylene coalescing and adsorption media help capture both free and emulsified oil contaminants.
- Activated-carbon-free filtration: Simplifies replacement media handling and lowers filter-kit weight.
- Compact, serviceable design: Helps conserve space while providing access for scheduled maintenance.
- Drain flexibility: Compatible with float-type, timer-operated and zero-loss condensate drains when installed correctly.
- Verified separation performance: KSI reports third-party testing and residual oil content below 10 ppm in its specifications.
- Application-specific media: Dedicated versions for mineral-oil condensate and synthetic lubricants / stable emulsions.

CFM ratings are manufacturer-listed compressor capacities. Separator selection may require adjustment for condensate volume, oil type and site conditions. Below-10-ppm separation performance does not guarantee local wastewater discharge permission.
Where to Use the KONTREC S450
For condensate management at machine shops, automotive service facilities, fabrication plants and industrial compressor installations where oil-lubricated compressed air equipment produces condensate. Match separator capacity and lubricant compatibility to the actual compressor system.
How the Separation System Works
Condensate enters the separator, allowing entrained compressed air to depressurize and escape through vent openings. Polypropylene media helps coalesce and adsorb oil; the first stage also retains solids that could load later media. A second stage removes residual oil components from the wastewater.
On the S150 and larger models, a primary filter section provides initial condensate separation and pressure relief. Felt material captures solids before the liquid reaches subsequent filtering stages.
Installation and Maintenance
Route compatible condensate drain lines to the designated inlet connections. Follow KSI instructions for location, venting, outlet routing and filter service. Monitor treated condensate as required by your local wastewater authority and change the specified filter kit according to operating conditions and maintenance guidance.
Recommended Accessories
Pair the separator with a properly specified condensate drain and keep replacement media available to minimize maintenance delays. Select KON-Kit450 for the mineral-oil version or KON-Kit450-K for the synthetic/emulsion K-type. Contact Compressed Air Advisors for help identifying the correct drain, fittings and media.

Frequently Asked Questions
Which KONTREC S450 version should I order?
Select KON-S450 for mineral-oil-based compressor lubricants. Select KON-S450-K for synthetic lubricants or stable emulsions. If lubricant type is uncertain, confirm the condensate characteristics before choosing a version.
What compressor capacity is the KONTREC S450 rated for?
KSI lists the S450 at up to 450 CFM compressor capacity. Actual separator sizing depends on operating conditions and condensate loading; verify the application and the manufacturer's sizing guidance.
Can treated water be discharged into a sewer?
KSI lists residual oil content below 10 ppm under its published specifications. Local wastewater limits, test requirements and facility permits still govern discharge. Verify compliance before releasing treated condensate.
Does the separator use activated carbon?
No. KSI specifies polypropylene coalescing and adsorption media rather than activated carbon. Its filter stages are designed to remove free and emulsified oil components from compressor condensate.
What condensate drain types can feed the unit?
KSI identifies compatibility with float-type, timer-controlled and zero-loss condensate drains. Install the separator as directed so any entrained compressed air can vent safely.
What replacement filter kit is needed?
The standard S450 uses KON-Kit450, while the K-type version uses KON-Kit450-K. Match the maintenance kit to the separator variant and follow the manufacturer’s replacement recommendations.
What connections are required?
This model uses 4 × 1/2 in. inlet connection(s) and a 3/4 in. clean-water outlet. It also provides a 1/4 in. test drain. Check hose and fitting compatibility during installation.
How frequently should the media be replaced?
Replace the filter kit based on the manufacturer's maintenance guidance, observed condensate loading and outlet-water monitoring. The specified maximum oil absorption capacity is not a fixed service interval.
Where should the separator be installed?
Locate it where condensate from the compressed-air system can enter the designated inlet and treated water can be sampled or discharged in compliance with local regulations. Keep vent openings clear and allow sufficient maintenance access.
Does Compressed Air Advisors offer compatible condensate drains?
Yes. Compressed Air Advisors can help identify suitable zero-loss and other condensate drain options, plus the correct maintenance filter kit for your separator.
