  1. Pour coolant or cleaning solution into the Separating Tank before using Jet Skimmer.
  2. Oil and coolant collected by Jet Skimmer flows into No.1 tank after floating oil and sludge are removed through the Mesh Tray.
  3. Oil having lower specific gravity floats to the surface and goes out through the oil outlet.
  4. Other liquid flows beneath the partition plate, then moves to No.2 tank and flows through the pipe to be returned into the coolant tank from the water return inlet.
*Separation Tank and Gauge Tray are option. See “Option" .

Operation behavior (in basic operation)


Jet Skimmer behavior
Performs battery charging. Motor is not running.
Inside coolant tank
When machine is operating, power is supplied to JET SKIMMER and coolant in the tank is agitated. Oil is mixed in the coolant fluid.

Jet Skimmer behavior
Jet Skimmer switches to battery-driven operation. Motor starts to work either three minutes or thirty minutes (selectable) after machine stoppage.
Inside coolant tank
After machine stoppage (power disconnection), oil mixed in coolant floats to the surface.

Jet Skimmer behavior
When floating of oil finishes, the motor starts operation for one(1) hour powered by the battery. While the motor is rotating, the belt catches oil on the liquid surface and the scraper removes oil from the belt.
Inside coolant tank
Floating oil is collected by Jet Skimmer.

Collection capacity comparison

①When operated JET SKIMMER for one hour after agitating coolant in the tank (assuming machine is in operation)
②When operated JET SKIMMER for one hour without agitating coolant in the tank (assuming thirty minutes after machine stoppage)


Testing conditions
Size of coolant tank W800 × H500 × D800(mm) : 150L
Cutting water: 100L(coolant solution diluted 25 times, containing floating oil of 4L)
*Concentration test method is according to JIS evaporation residue test method.

Power consumption comparison

JET SKIMMER Conventional oil skimmer
Conditions for comparison 2 hours/day charging during machine operation and 1 hour operation after power disconnection to machine 8 hour operation per day
Power consumption 20W (Charging time) 15W
Power consumption per day 16.4Wh/day 120Wh/day
