Installation of Filtermist S800 Oil Mist Extraction on XYZ RMX2 CNC Machine

AES engineers installed a Filtermist S800 unit mounted on a top half wall bracket, incorporating:

• Machine Stand & Oil Return Hose
• High‑efficiency AfterFilter
• Flexible hose connection
• Filtermist F-Monitor 2 for real-time airflow/service alerts

Following installation, AES carried out full LEV commissioning performed by a BOHS P601-qualified engineer. A comprehensive LEV report, logbook, and digital/physical documentation were supplied to ensure full compliance and easy ongoing maintenance.

The Filtermist S800 installation delivered:

• Efficient removal of oil mist and coolant aerosol directly at source
• Compliance with COSHH and HSG258 LEV regulatory requirements
• Improved workshop air quality
• Cleaner machine interiors and reduced contamination of components and electronics
• Safe return of clean air to the factory environment
• Reduced slip hazards and safer operator working conditions
• Visibility improvements inside the machine enclosure, supporting quality control
• Real-time condition monitoring via the F‑Monitor, ensuring optimal performance and simplified servicing

APH Hydraulic Engineering can now operate the XYZ RMX2‑OP with confidence, knowing that airborne contaminants are effectively captured and controlled, protecting their workforce and extending machine life.

Installing a Filtermist extraction system—particularly the S800, recommended for CNC machines up to ~2.0 m³ internal volume—delivers multiple operational, safety, and financial benefits.

1. Improved Air Quality & Operator Health

Oil mist is hazardous when inhaled and can lead to respiratory conditions. Filtermist units remove mist and fume at source, ensuring a cleaner and safer workshop environment.

2. Compliance With COSHH & HSG258

Filtermist systems are fully compatible with UK LEV requirements, helping machine shops meet their legal obligation to control airborne contaminants. AES provides full LEV commissioning, reports, and logbooks to maintain compliance.

3. Cleaner Machines & Reduced Maintenance

Oil mist can cause buildup on:

• Machine components
• Electrical circuitry
• Ventilation ducts
• Fluid management systems

The Filtermist design removes mist before it escapes the enclosure, reducing cleaning frequency and improving machine uptime.

4. Enhanced Visibility and Part Quality

Mist‑filled machine enclosures reduce visibility during machining. By extracting airborne coolant aerosols, operators can better monitor toolpaths and surface finish, supporting more consistent quality.

5. Prevention of Slips and Workplace Accidents

Oil mist settles on floors and surfaces, creating slip hazards. Filtermist units significantly reduce accumulation, resulting in a safer workshop environment.

6. High Efficiency Filtration With Afterfilters

The High‑Efficiency AFB afterfilter provides 99.95% filtration at 1 μm, ensuring the final discharge air is clean and can be safely returned to the workshop.

7. Smart Monitoring for Predictive Maintenance

The F-Monitor 2 offers:

• Traffic‑light status indication
• Airflow and time monitoring
• Optional vibration/temperature sensor
• Bluetooth connectivity and mobile app access

This helps operators detect drops in performance, blocked filters, or servicing needs before they affect production.

8. Low Noise & Energy Efficiency

The S800 runs at only 67 dB(A) and recycles clean, warm air back into the workshop—reducing the need for costly extraction-to-atmosphere systems.
