22. Veldi Respiratory unit Respiratory Unit: Awareness Money Control on legislation Global ?! $ USA Europe Asia

23. Veldi Respiratory unit Global ?! $ America:  Companies responsible for workers safty  Over-exaggerating: very safe look Asia:  Companies choose equipment of the welder  Clean, with a high level of technology Europe:  Workers choose their own r.p.u  Appreciate innovative design and ergonomics

24. Veldi Respiratory unit Legislation ?! $ NEN & CE norms  Air flow >120 l /min.  pressure in helmet <7 mbar.  duration of batteries >4 h.  noise of the device <75 dB.  thread for apparatus M45x3.  Recommended voltage <60 V (D.C.) or <25 V (A.C.)  Hoses and couplings >(500  50)N applied axially for (10  1)s.  Total mass <5 kg  Weight on the head<1,5 kg

25. Veldi Respiratory unit Problem Definition Safety  Indication when the filters have to be replaced.  After welding it should be possible to remove the headpiece, but to keep the respiratory protection on.  No parts of the r.p.u. should stick out of the back of the welder. ? ! $

26. Veldi Respiratory unit Problem Definition Ergonomics  Easy replacement of the filters.  Indication of full filters  Low level of noise (< 75db).  Vibrations from the motor should not reach the welder.  The airflow should not cause discomforts while being used.  The r.p.u. should not limit the sight on the work piece. ? ! $

27. Veldi Respiratory unit Problem Definition Technique/adequate performance  The inside of the unit should be protected against dust and small particles, to increase lifetime of the motor  The weight of the battery should become less then 1/3 of the present battery  The welding sparks should not affect the r.p.u. ? ! $

28. Veldi Respiratory unit Problem Definition Global Design  The r.p.u. should have a uniform look, in stead of just a combination of different parts.  The r.p.u. should look conform the preference of American, Asian or European market. ? ! $

29. Veldi Respiratory unit Problem Definition Financial advantage  Where possible use of standard products  Avoid complex design of the non-standard parts  As few parts as possible, avoid screws  Finding a compromise between costs of dismantling and lowest possible costs of the R.P.U ? ! $

30. Veldi Respiratory unit Conceptualization use ? ! $ Easy replacement of batteries: like in a walkman Indication of full filter: Printplate measures the airflow: low airflow indicates full filter or empty battery Free body Movement: Integrated filter/motor in helmet: no hose Separate moving mask

31. Veldi Respiratory unit Weight & seize ? ! $ less parts: integration Motor & printplate cover Filter-topcover 1. Belt-battery 2. NiHydrid-battery Volume:

32. Veldi Respiratory unit Global ? ! $ Batteries: Sold in pack and also separate > obtainable everywhere Filter: Bigger diameter > One size filtercasing beholds all kinds of filters combinations longer lifetime of filter: Filters that dont fulfil the most severe regulations can be sold in other countries for less money Change of filter = change of casing Transparent

34. Veldi Respiratory unit Life cycle analysis of the models with Tornado ? ! $

35. Veldi Respiratory unit Conclusions LCA 1.The two models have similar financial lines, 2.The disassembly time of the two models is much shorter with respect to that of Tornado, 3.The total cost/profit cumulative of the two models is much lower with respect to that of Tornado. From the end-of-life comparison of the two models with Tornado, we can see that: These characteristics are very important since in the near future, producers will have more responsibilities about the treatment of their end-of-life products. ? ! $

36. Veldi Respiratory unit Conclusions LCA 1.The two models have similar environmental effects (MET points) lines, 2.The total environmental effects of the two models is worse with respect to that of Tornado, 3.The difference is more significant at the production stage, 4.There is a potential for improvement by focusing on types of materials (thermoplastics), weights of parts and manufacturing processes, 5.The end-of-life destinations associated to disassembled parts are compliant with legislation even if they have negative environmental effects. With respect to the priorities of the near future: globalisation, lower end-of-life costs and compliance with legislation on environment, we can consider that the developed models are quite satisfactory. From the life cycle comparison of the two models with Tornado, we can see that: ? ! $
