10. HEATING COOLING DEHUMIDIFYING AIR FILTRATION What is Air Quality? “Healthy Air” –Ambient or indoor air which is free from harmful contaminants and contains 19.5 to 22% oxygen (suitable for breathing) “Clean air” –Air of such purity that it will not cause harm or discomfort to an individual if it is inhaled for extend periods of time OSHA Regulations (stds-29 CFR) Ventilation – 1926.57

11. HEATING COOLING DEHUMIDIFYING AIR FILTRATION Ventilation Issues Chemicals/Fumes –Paints, Glues, Varnishes –VOCs-carpeting, cabinets, furniture Dust/Particulates –Diesel exhaust –Grinding/Sanding o Silica, Lead –Welding o Galvanized steel-CR, NI o Stainless Steel-ZN, flux HEATING

12. HEATING COOLING DEHUMIDIFYING AIR FILTRATION Safety Issues Use of Outside Air Can Help Reduce Safety Concerns Ventilation of Harmful Fumes –Paints, Glues, Varnishes, etc. –3 main byproducts of combustion o CO, CO2, H2O Carbon Monoxide (CO) Reduction –OSHA levels –Many sources on a job site HEATING

13. HEATING COOLING DEHUMIDIFYING AIR FILTRATION Direct Fired Make-up Air Pressurizes the structure –Minimizes infiltration & cold spots Uniform heat distribution Controlled ventilation (0.5- 1.0 AC/Hr) Absorbs moisture,ventilates toxic fumes and excessive moisture Lowers relative humidity levels and dew point surface temperatures HEATING
