Choosing the right filtration system plays a key role in maintaining machine performance and reducing production waste. This article outlines 3 practical steps to help factories select the ideal filter for coolant systems, improving product quality and minimising long-term costs.


■ Why Filtration Systems Matter in Factories
Metalworking factories—such as those involved in cutting, grinding, or CNC machining—often face problems like:

- Coolant contaminated with metal debris
- Frequent machine breakdowns
- High filter maintenance costs
- Inconsistent surface finish and increased NG (No Good) rate

These issues typically stem from using the wrong or inefficient filter. With proper selection, factories can significantly reduce downtime and extend machine service life.


■ 3 Steps to Choose the Right Filter

✅ Step 1: Identify the Type of Waste in Your Process
Grinding and turning processes generate fine metallic debris, requiring filters with precise capture capabilities. For coarse particles, a basic bag filter may be sufficient.

✅ Step 2: Match Filter Type to Your Factory Layout
- Limited space? Cyclone filters are compact and require no consumables.
- High steel debris? Magnetic filters are ideal for capturing ferrous particles without frequent replacement.
- Need high-flow filtration? Bag filters suit large coolant volumes.

✅ Step 3: Focus on Long-Term ROI
Don’t just choose the cheapest option. Filters that require less frequent maintenance save more in downtime, labour, and part damage over time.


■ Recommended Filter Types

🔹 Bag Filter (RBF Series)
- Simple structure, easy to clean
- High flow rate, reliable secondary filtration
- Ideal for: CNC and grinding lines requiring coolant clarity

🔹 Magnetic Filter (MF Series)
- Captures fine ferrous particles using powerful magnets
- Minimizes filter change frequency
- Ideal for: Lathing and drilling processes with heavy metal debris

🔹 Cyclone Filter (APS Series)
- Uses centrifugal force to separate solid particles
- > 90% efficiency for particles ≥10 microns
- Ideal for: Tight spaces with continuous filtration needs


Conclusion:
Choosing the right filter not only prevents machine failure but also improves product quality, reduces NG waste, and cuts operational costs. Start by assessing your process needs and matching them with the filter type that provides long-term benefits.
