The attached ROI Analysis Spreadsheet will assist you in calculating savings in using our RESPA CF / CFX PFP Systems over that of other conventional PFP's.

Simply add your own data to the "yellow" highlighted fields and the rest is calculated for you- the results are quite significant!

The ROI Analysis Spreadsheet:

Only Considers:

  • Costs of Filter Element Replacement + Labour +Replacement of Capital Equipment
  • Use of both External Air PFP and Recirculation Air PFP with HEPA Grade Filters so as to meet NOHSC / Worksafe OEL compliance.

Does not Consider:

  • Maintenance costs with current PFP- Tubing, Bracketing, etc  
    Productivity loss due to In- Pit service calls- eg current Filters to do meet machine 250 or 500 maintenance intervals.
  • Component failure due to ingress of contamination causing premature failure of HVAC, Evaporator, Fans, etc.
  • Lower costs for installation of RESPA compared to other PFP Systems.

Please note also that:

  • National Exposure Standards for Atmospheric Contaminants in the Occupational Environment [Worksafe- NOHSC: 1003(1995) legislates that OEL (Occupational Exposure Limits) for Respirable Crystalline Silica (RCS) should not exceed 0.1 mg / M3 air TWA 8 hour shift. For a 12 hours shift using the Brief and Scala adjusted calculation, OEL should not be more than 0.05 mg/ M3 TWA (Time Weighted Average).
  • Respirable Dust is sized between 0.5 micron and 10 micron and so to meet the NOHSC: 1003 OEL all HVAC Filter Elements for External and Recirculation Air must be HEPA grade so as at to remove all particulate above 0.3 micron @ 99.97 arrestance efficiency.
  • RCS is found at varying levels in all dust, especially within the Mining, Quarrying, Construction, Earthmoving as well as many other Industries.
