Smart Disk Skimmer
115V (US) units ship with a standard US plug.
Which reach do I order?
Pick the disk by tank size and oil load: 12 in for an ordinary sump, 18 in when the sump is large or the oil comes in fast, 24 in for the biggest tanks. Pick the high-temp black disk if the coolant runs hot or the fluid is agitated. The Speed picker is a motor choice, not a size choice. Not sure? Send two photos through the contact page and we tell you.
| Your situation | Pick | Price |
|---|---|---|
| Ordinary coolant sump, moderate oil load | GS4H300 (12 in high-impact disk, 7 rpm) | $378 |
| Bigger sump or heavier oil load: 18 in disk pulls about 3 quarts an hour | GS4H460 (18 in high-impact disk) | $510 |
| Largest tanks | GS4H610 (24 in disk, 2 rpm) | $585 |
| Coolant runs hot (over 90 F) or the sump is agitated | GS4W models: high-temp black disk, good to 212 F | from $486 |
| Oil film is thin or the fluid foams: slow disk sheets the oil off cleanly | Slow (2 rpm) in the Speed picker | from $378 |
| 220 V shop power | 220V (Europe) in the Voltage picker, 6 rpm at 50 Hz | from $378 |
Reach is measured from the mounting surface down to the coolant, not the tank depth. Not sure? Send us two photos and we will tell you.

Boost Efficiency and Savings with Smart Disk Skimmers
The Smart Disk Skimmers are an excellent solution for heavy loads of tramp oil floating on the coolant. Choose from our original disk skimmer or the more advanced smart disk oil skimmer with the integrated Diverter™. The Diverter helps separate tramp oil from your coolant and then returns clean coolant to your sump. The Smart Disk Skimmer is covered by our Lifetime warranty. Belt, tube or disk? Our guide to choosing an oil skimmer explains when a disk wins.
Your purchase includes:
- 1 Smart Disk Skimmer with a 2 or 7 rpm continuous duty 115v motor (based on order)
- 1 set of wipers
- 1 disk (either a 12" or 18") based on purchase
Key Features for Smart Disk Skimmers
- Cost-Effective: Save nearly $300 compared to other disk skimmers in the market. It’s the most economical disk skimmer designed specifically for coolant use. Run the payback on our coolant skimmer ROI calculator.
- Built-in Diverter™: Every disk lifts a little coolant along with the oil. The wipers scrape both into the Diverter, a small steel box under the wipers with two chambers and two brass outlets. The oil floats to the top and runs out one outlet to your waste container; the coolant settles underneath and drains out the other outlet back into your sump. What you throw away is oil, not coolant.
- Durability: Built with heavy-duty steel construction to ensure longevity and reliable service.
- Disk Options: High impact (White) and High Temp (Black). Picture with black disk shows a high temp disk installed. Custom disk sizes are available from Zebra engineering.

Product Videos
Smart Disk Skimmers helps mitigate coolant wasted during the skimming process and with the attached diverter which returns clean coolant to the sump. Zebra’s offers two disk skimmers, our original disk skimmer and the smart disk oil skimmer. Both are ideal for handling heavier oil loads. The Smart Disk Skimmer separates the tramp oil and returns clean coolant to the tank.

Questions shops ask before they order
Which disk do I order?
Pick the disk by tank size and oil load: 12 in for an ordinary sump, 18 in when the sump is large or the oil comes in fast, 24 in for the biggest tanks. Pick the high-temp black disk if the coolant runs hot or the fluid is agitated. The Speed picker is a motor choice, not a size choice. Not sure? Send two photos through the contact page and we tell you.
What does the diverter do?
Every disk lifts a little coolant along with the oil. On the Smart Disk the wipers scrape both into the Diverter, a small steel box under the wipers with two chambers and two brass outlets. The oil floats to the top and runs out one outlet to your waste container. The coolant settles underneath and drains out the other outlet back into the sump. So the waste container holds oil, not coolant, and the sump keeps its coolant. The LH Series disk skimmer has no diverter: what its wipers scrape off goes straight to the waste container.
Standard or slow motor?
Standard 7 rpm suits most sumps. The 2 rpm motor turns the disk slowly enough that a thin film of oil clings to it without stirring the coolant, which helps on foamy or lightly oiled sumps.
What wears out?
Wipers and the disk are wear parts and are stocked. The skimmer itself carries our lifetime warranty.
