1. Philosophy Offer unique technology Separate majority of fluid without filters Quickly drain fluid to reduce evaporation Clean air must approach zero emissions Low maintenance Low life cycle costs Customer must always be 100% satisfied

2. Clean Air will Approach Zero Mist

3. Oil Mist Limits OSHA < 5.0 mg/m³ Recommended < 0.5 mg/m³ NIOSH < 0.4 mg/m³ (time weighted average over 8 hrs) Most companies with H&S and unions are using limit < 0.5 mg/m³

4. HEPA Filters for Clean Air With HEPA clean air can be <0.020 mg/m³ Without HEPA most eliminators are above 0.5 mg/m³ and don’t remove smoke, steam or bacteria Fine mist & bacteria is the major cause of health problems

5. Health Issues Headaches Nose Bleeds Sionasal Cancer Sore Throat Lung, Skin, & Stomach Cancer Asthma Respiratory Damage Hypersensitivity Pneumonitis Eye Irritation Acne Eczema Dermatitis Allergic Reactions Body Odor

6. Steam vs Smoke Steam – Cutting tool temp > 212ºF Smoke – Cutting tool temp > 300ºF Look at chips - Blue chips – steam - Brown chips – smoke High tramp oils in coolant increases smoke

7. Mist Distribution Curve Particle Count Oil smoke Oil-mist 0.1 0.3 1 10 100 microns

8. Sizing Guidelines Machines with low mist generation, infrequent door opening:- Enclosure volume (ft³) x 2 to 3 = cfm Machines with medium mist generation, average door opening:- Enclosure volume (ft³) x 4 to 5 = cfm Machines with high mist/smoke generation & frequent door opening Enclosure volume (ft³) x 6 to 10 = cfm For enclosures with open areas add :- 75 – 200 cfm per ft². Hoods :- 75 – 200 cfm/ft² Note: the factor number used is the number of air exchanges per minute. Example 4 :- 4 per minute or every 15 seconds.

11. 1 st stage Mechanical Separation Elements 2 nd stage Aggomerator Depth Filter

12. 2 nd Stage Filter Options 1- Permanent media filter 10 – 15 years Excellent on coolant Can add wrap for fine mist applications. Optional On-Line-Cleaning system No competitor comes close to the life service of this filter.

13. Permanent 2 nd Stage Filter Air Flow Drainage Made in Layers (8) SS wire mesh weaved with fibers Excellent drainage. Difficult to blind. Durable/long life, 10 - 15 years Can be cleaned. Fine fiber layer. Larger fibers provides channel for drainage.

14. 2 nd Stage Filter Wrap For oil and fine mist applications Single wrap – fine coolant or cast iron Double wrap - oil Will reduce air flow 100 – 200 cfm

15. On-Line Cleaning System Optional: Flushes out congealed concentrates and solids from 2 nd stage filter. Flush every 1-4 months with coolant or water. Shut-off fan motor, open manual flush valve for 5-15 minutes. Coolant or water flows back to sump. Note: on 98% of applications, filter stays clean w/o cleaning for 4 yrs or more.

16. 3 rd Stage Filter Options, ROX-400/600 One 4” filter makes compact dimensions for mounting on small machines. Two 4” filters will provide close to HEPA quality air. 12” HEPA 95% @ 0.3 microns for the best air quality

17. ROX-400/600, one 4” filter One cabinet size. Two air flows Compact dimensions for small machines 26” x 21” (1 x 4” filter)

18. ROX-400 / 600 one cabinet size, two air flows

19. ROX-800 / 1100 One cabinet size, two air flows

20. ROX-2000 Can be ganged together to make 4000, 6000, 8000 cfm etc central systems.
