In a workshop that uses cutting, grinding and sanding equipment, dust in the air is inevitable.

This is most common in woodworking shops where large amounts of sawdust and woodchips are released into the air as we work. Shops that deal with stone have a bigger problem because many stone products release minute particles that contain crystalline silicone and the health effects from inhaling silicates is particularly dangerous.

This is also true for contractors who cut masonry and stone on site. The main effects of dust or sawdust in the air is that they cause damage to the respiratory system, resulting from particles collecting in the lungs. Breathing in any amount of dust over a prolonged period can cause irreparable damage to your lungs.

Other health problems can be scratching of the eyes and, in some cases, skin irritation. Most woodworking shops will use dust extraction systems that are connected to the machine — usually dust collection bags attached to a vacuum system. These systems are very effective and remove a lot of the wood-chips and sawdust released by the tools that we use. However, there is always dust that is not collected by a conventional dust extraction system.

Small particles of 5-micron or less become airborne very easily and these particles are the most dangerous — causing the most damage to our lungs. They are too small to see and will go by unnoticed unless they are in large volumes.

This causes a fine mist in the air. Because most of the fine dust is not collected by regular dust extraction systems, a secondary air filtration system is of great importance. Not only are particles in the air a cause of health problems, but they can also have a negative effect when applying finishes and paint to the final product. In the US, indoor air quality regulations are a legal requirement for employers in two states — New Jersey and California.

Despite the lack of federal legislation for air quality in the workplace, labor law does state that all workers have the right to a safe and healthy working environment. By default, this means that if the air in the workplace poses a health risk to your employees, you are in contravention of the law — no matter what the state laws are. This is why any workshop Wood Workshop Air Filtration System 2020 that produces dust needs an air filtration system that is capable of removing dangerous particles from the air.

This means that it needs to have the correct filters, normally removing particles of up to 1-micron in size. To give you an idea of what this is, 1 micron is 0. For most shops, a 1-micron filtration system is fine for solid matter particles. An HEPA filtration system will remove particles of 0. Your workshop air filtration system needs to clean the air in the shop times per hour. This means that the entire volume air in the area needs to pass through the air filtration system at least six times every hour.

An air filtration system uses a fan to draw air through the filters and release it back into the atmosphere as clean air without any harmful particles. To do this you need to calculate the volume of your shop Length X Width X Height , you then multiply this by the number of times you want the air to be cleaned and divide your final answer by Installing an air filtration system is not complicated.

Larger units may require a V circuit and may also require heavier mountings as these will be heavier machines. Generally, people prefer to hang the air filtration system from the ceiling and most of the smaller models have eyes or hooks to make this easy to do.

Placing the filtration system too close to a wall or workbench will obstruct the airflow. This will provide the best air circulation around the room.
