Having fresh air along with adequate ventilation serves many more purposes than just the well-being and comfort of occupants. Although a supply of clean air is very important, these systems are also capable of providing condensation control along with the removal of airborne pollutants. In this article we will take a closer look at industrial ventilation systems.
The word ventilation basically means the movement of air from the outside of a structure or building to the inside, and there are many different types products available in order to handle this, from fume extraction systems to more specialized applications such as welding fume removal.
Industrial units will help with the controlling of workers or employees being exposed to various airborne toxic chemicals or from flammable vapors by moving the contaminated air away from the area and subsequently replacing it with fresh clean air. It is the most widely used way in which companies decrease exposure to harmful air contaminants in their workplace. These systems also can remove such things as oil mist and dust, fumes from solvents, etc. And will exhaust these outside.
Generally, the maintenance of as well as troubleshooting of this kind of system will normally be handled by a qualified engineer or a firm that specializes in this field. The amount of worker exposure to certain contaminants is tightly controlled by occupational health regulations, and some of the conditions include lowered oxygen levels, levels of airborne contamination that has risen above permissible exposure limits, and also explosive limits concerning flammable vapors.
Some of these systems will operate on the principle of moving the air from areas of high pressure to low pressure and this is accomplished by a fan which will draw air through the ventilator, and these are normally found as close as possible to the contamination source, therefore being able to capture it before it is actually released back into the work area. It usually has several basic elements, including a hood, the duct, a cleaning device and also the fan and exhaust stack.
With any of these kinds of units, the fan is one of the most important. They should be the appropriate type as well as size in order to make everything work effectively, and should also provide sufficient air pressure difference to be able to carry everything efficiently. There are two main types, centrifugal and axial, and both are very effective with rugged blades.
If your existing unit seems to be not functioning properly, there are a few simple checks that can be made without having expert help, and these may include such things as checking for fan belts which are broken or are slipping, ducts that may be clogged with dust, dampers in the duct work which may have closed up, holes or cracks in the ducting as well as air cleaners that may have become clogged up.
Usually most of these problems can be avoided by having periodic maintenance and servicing. There are many companies that provide industrial ventilation as well as heating and cooling for homeowners and most can be found in your local yellow page directory.
