Machining coolant picks up floating oil, while chip bins hold coolant-soaked metal. One filtration separation product takes oil off the surface of cutting fluid; the other spins solid loads to separate liquid from solids. The right choice depends on where your mess is: in the sump or in the chip container.
Quick verdict
If your pain point is a layer of floating oil on top of machining coolant, the Maisutseb® 208-240V 3-Phase Industrial Oil-Water Separator Oil Skimmer for Cutting Fluid is the direct response, and at $1,886 it is the lower listed price in this pairing. If your pain point is wet chips, small parts, filings, or a need to separate liquids from solid loads, the TECHTONGDA Industrial Centrifuge Dehydrator Biomass Oil Extraction Solid-Liquid Separator at $4,646 is the stronger match for bulk dewatering.

Where each product wins
- Fluid life extension: The Maisutseb® separator is built to pull floating oil out of cutting fluid before it degrades coolant, which makes it a natural fit around machine tool sumps.
- Bulk solids handling: The TECHTONGDA centrifuge accepts metal chips, filings, and small hardware and spins them at 660 r/min to strip coolant and oil from the load.
- Repeated batch work: TECHTONGDA offers a stainless steel barrel and semi-automatic control, while the Maisutseb product focuses on removing oil from a sump.
Product notes
Maisutseb® 208-240V 3-Phase Industrial Oil-Water Separator Oil Skimmer for Cutting Fluid
The Maisutseb oil-water separator is purpose-built for a very specific problem: floating oil in machine tool coolant. By recovering that oil, it can extend the life of cutting fluid and keep the work environment cleaner. It is a New product priced at USD 1,886.00, and the product name makes its intended use clear: 208-240V 3-phase shops working with cutting fluid. The separator is the lower-priced option in this head-to-head, which matters when your only filtration separation bottleneck is sump oil. However, it is not a centrifuge: it won't take a batch of chips or small parts and spin them dry. If you need dehydration of solid loads, this skimmer is the wrong tool for that job.
TECHTONGDA Industrial Centrifuge Dehydrator Biomass Oil Extraction Solid-Liquid Separator
The TECHTONGDA centrifuge dehydrator takes the opposite approach: it loads metal chips, iron filings, aluminum filings, copper filings, and small hardware into a stainless-steel rotating hub to separate coolant and oil from solids. At 660 r/min, with a semi-automatic foot-switch unload design, it is built for repeated batch dewatering. The price is USD 4,646.00, the higher figure in this head-to-head, and the stainless steel barrel supports routine shop use. TECHTONGDA does not position this as a sump skimmer, so if you only need to pull floating oil off cutting fluid, this centrifuge won't replace the Maisutseb separator. Choose it instead when your work is chip dewatering, oil extraction from solid material, or degreasing small parts in batches.
Final choice by use case
- For machining coolant maintenance: Choose the Maisutseb® oil-water separator at $1,886 when your goal is to keep cutting fluid usable by removing floating oil.
- For solid load dewatering: Choose the TECHTONGDA centrifuge dehydrator at $4,646 when your goal is to dry chips, recover oil from solid material, or degrease small parts in batch.
Match the $1,886 tool to the sump, and the $4,646 tool to the chip bin.
