LW Series Oil-Water Separator and Coolant Purification System
LW Series Oil-Water Separator｜Coolant Floating Oil Separation and CNC Tank Maintenance Solution
The Bautai LW Series oil-water separator is designed for CNC coolant tanks, coolant circulation systems, and metalworking environments. It helps separate floating oil, tramp oil, and oil contamination from the coolant surface, allowing oil contamination to be collected and discharged more efficiently.
Through pneumatic drive and physical separation structure, the LW Series helps reduce floating oil accumulation, coolant odor, coolant deterioration, bacterial growth, and manual skimming workload. It supports longer coolant service life and reduces the pressure of coolant replacement and waste liquid treatment.
Improving Floating Oil and Coolant Contamination Problems
In CNC machining environments, slideway oil, hydraulic oil, and machining oil contamination may mix into the coolant tank and form floating oil on the surface. Over time, this can cause odor, bacterial growth, coolant deterioration, and increased tank cleaning workload. The LW Series continuously draws surface contamination and separates oil from coolant to help maintain coolant cleanliness.
Pneumatic Drive, Stable Operation, and Lower Maintenance Cost
The LW Series adopts a pneumatic drive design, reducing electrical spark risk and making it suitable for long-hour operation in machining environments. With physical separation and low-consumable design, it helps reduce filter replacement needs, maintenance cost, and downtime for tank cleaning.
Product Advantages
Energy-Saving and Safe Operation
Pneumatic drive reduces electrical spark risk and supports safe operation in machining environments.
Physical Separation Design
Helps separate floating oil, tramp oil, and oil contamination from coolant through physical separation principles.
Strong Suction Performance
Quickly draws floating oil and surface contamination to improve coolant tank circulation cleanliness.
Low-Consumable Design
Reduces frequent filter replacement needs and helps lower long-term consumable and maintenance costs.
Extended Coolant Service Life
Helps reduce contamination recirculation and supports longer coolant and processing fluid service life.
Application Scenarios
Single-Machine and System Applications
LW-M15 is suitable for one-to-one operation with a single machine, while LW-S20 adopts a mobile design for different coolant tanks or multiple machines. The LW Series can also be integrated into factory fluid management systems, circulation tanks, and downstream water treatment processes to improve overall fluid cleanliness.
LW Series Specifications
Select the suitable LW Series oil-water separator according to coolant tank capacity, floating oil volume, operation method, and on-site installation requirements.
Mobile High-Capacity Model
Suitable for larger coolant tanks, higher floating oil volume, or applications requiring flexible movement between multiple machines. Equipped with wheels and a handle for easier relocation without repeated leveling.
Single-Machine Fixed Model
Designed for one-to-one use with a single coolant tank. The compact body and reserved mounting holes make it suitable for fixed installation on individual machining equipment.
Model Selection Guide
Both LW-S20 and LW-M15 are pneumatic oil-water separation systems. The main differences are coolant tank capacity, structure design, and installation method. LW-S20 is recommended for mobile use, larger coolant tanks, or multiple machines, while LW-M15 is suitable for fixed one-to-one single-machine applications.
