Air Exhaust and Ventilation in the Workplace:
Whether exhausting harmful chemical fumes or just cooling your facility to increase employee efficiency, Industrial Fans Direct.com has the answer. Did you know that heat stress is a serious problem in the work place? Heat stress is an indicator of unsafe, unhealthy work conditions. Like other unsafe work conditions, heat stress lowers productivity and morale, allowing accidents and errors to occur. Our commercial and industrial grade exhaust and ventilation type fans can help to create a cooler more comfortable work environment, which can directly contribute to productivity, quality and profitability.

Adequate ventilation in any workplace is essential for good health and productivity. A well-designed and efficient ehaust ventilation system has many benefits, including:
1. reducing exposure to airborne hazardous substances thereby preventing work-related illness, absenteeism and turnover;
2. preventing the accumulation of heat in the workplace thereby preventing heat stroke and heat exhaustion;
3. reducing time and money spent on inspection and cleaning of raw materials, semi-finished products and final products when dust, oil, organic solvents and other airborne substances are kept to a minimum;
4. reducing costs for electricity;
5. increasing productivity when the working environment is comfortable and well-adapted to the needs of the workers.

Use Intake Type and Exhaust Type Ventilation Fans Properly:
There are two types of ventilation using electric powered fans: intake or supply type fans and exhaust ventilation type fans. The combined use of intake and exhaust can increase greatly the efficiency of ventilation

Here are some tips:
1. use intake or supply fans to provide a strong air flow which can reach a distant place. Use intake or supply fans if there is no risk of scattering airborne contaminants.
2. use exhaust type fans to collect vented substances. Use it if there is a risk of airborne hazardous substances being scattered. The distance between the source of the contamination and the inlet of the Exhaust type fan(s) should be in close proximity. Suction power decreases exponentially as distance increases and is therefore weaker as one moves further from the opening;
3. a combination of intake / supply and exhaust type fans is the most efficient form of ventilation, although it can be costly to set up. This method overcomes the weaknesses of separate intake and exhaust type ventilation. intake / supply and exhaust ventilation can provide strong air flow to distant places without spreading contaminants. The capacity of the exhaust fan must be bigger than that of the pushing fan or contaminants will be spread throughout the workplace. Usually the capacity of an exhaust fan must be approximately 5 times greater CFM than that of a intake fan;
4. place sources of heat or sources of airborne hazardous substances close to exhaust ventilation fan(s) to ensure sufficient airflow for their removal.
