Oil mist generated during CNC machining can seriously impact air quality, worker safety, and equipment performance.
At A-Mac Environmental, we design and install COSHH-compliant Local Exhaust Ventilation (LEV) systems that capture and remove oil mist at source—helping manufacturers maintain safe, efficient, and compliant workplaces.
What Is Oil Mist in CNC Machining?
Oil mist is composed of fine airborne droplets produced when cutting fluids or lubricants are atomised during machining processes.
These particles can quickly spread throughout a workshop if not properly controlled.
Why It Matters:
Respiratory irritation and skin exposure risks
Oil contamination on machinery and electrics
Increased fire risk in enclosed environments
Slippery floors and poor housekeeping
Under COSHH regulations and HSG258 guidance, oil mist must be effectively controlled.
Common Sources of Oil Mist
Understanding the source helps design the right extraction system.
High-speed CNC cutting operations
Mist lubrication systems
High-pressure coolant sprays
Machine wear, leaks, and poor maintenance
The Most Effective Oil Mist Control Solution
Local Exhaust Ventilation (LEV)
LEV is the primary and most effective control method for oil mist.
It captures contaminants at source before they enter the breathing zone.
Our LEV Systems Include:
Custom-designed hoods and enclosures
Correct capture velocities (0.5–1.0 m/s)
Efficient ductwork design (10–15 m/s transport velocity)
High-efficiency filtration systems
✔ Fully compliant with COSHH & HSG258
✔ Designed for your specific CNC processes
✔ Installed and tested by qualified engineers (P601)
Oil Mist Filtration Technologies
We integrate industry-leading extraction equipment, including:
Coalescing filters – remove and drain oil droplets
Electrostatic precipitators (ESP) – ideal for fine mist
Centrifugal separators – effective for heavier particles
We work with trusted manufacturers such as Plymovent, Lajac, and Euromate Products.
CNC Machine Enclosures
Enclosing CNC machines improves extraction efficiency and containment.
Prevents mist escape
Improves capture performance
Supports cleaner working environments
Workshop Air Cleaning Systems
For larger facilities, we also install ambient air filtration systems to support LEV.
Reduces background contamination
Improves overall air quality
Ideal for multi-machine environments
