Industrial ventilation fans are typically used to get rid of hot, noxious, or contaminated air away from machinery and/or workers. Most are Axial Flo types. However, Centrifugal Blowers are used when a large static pressure is required when higher air velocities are needed or for long duct runs. Panel fans (or wall fans) are the most common industrial ventilation fan.
Maintaining a clean air supply is vital for a healthy, safe working environment. If a worker is exposed to contaminated air that is above the levels permitted by regulations and laws, the company must take immediate steps to fix the problem. Some examples of work areas that may be contaminated are welding areas, abrasive blasting areas, polishing areas, and spray paint booths.
The amount of air supply needed is determined by the size of the area that needs ventilated. To find out how much is needed, first multiply length times width, then times the height to figure out the cubic feet of the room. Then divide the cubic feet by the number of minutes for air change for that specific room. The answer will be the CFM needed to ventilate the room.
There is a reference chart in the Engineering Data catalog that shows the average recommended air changes to maintain good air quality. Air quality engineers or other trained professionals can also provide information on the requirements to avoid problems and to maintain good air quality.
Dust extract systems and equipment helps extract any dust from the system and is highly powerful. It is usually easy to install and typically made of quality raw material. Systems can be used to collect dust from things such as saws, grinders, and sanders. It is widely demanded in most industries and can be made to fit unique technical situations provided by the client.
Fume extraction arms extracts dust, smoke, and gases right from the source before it can contaminate the air and be inhaled. It provides a better working environment, and there is less wear and tear of the machines with very low cleaning costs. Local exhaust vents are used to minimize contaminants and the contaminant itself can be collected to safely dispose of or recovered. It also minimizes maintenance and repair on equipment because corrosive substances and heat responsible for damaging equipment are negated.
With the number of chemicals used today, along with exhaust gases, dust particles, and other types of pollution, industries are required to have completely effective clean air systems. The products should not have their own exhaust or venting problems. They should produce clean air at a low cost. Most companies are required to have some type of clean air system or they could be fined or even shut down.
Industrial ventilation fans, along with the other safety equipment, provide a safe and productive working environment for workers. The air breathed by everyone must be non-noxious and meet federal, state, and local regulations. Exhaust, fumes, and dust can present real and dangerous safety and health issues. Ventilation systems help reduce these issues.
