How Do Filters Work

How does an industrial filter work? Your automobile has an air filter and oil filter. Even your air conditioner has its own filter. Learn how bag filters can improve your work place indoor air quality.

How Does an Industrial Filter Work?
Soil, water and air are full of many different chemicals, compounds, metals and contaminants. Some are harmless and some are harmful. Filters are used in nearly every function you can imagine; your wife uses a type of filter (a strainer) to separate water from pasta.

The goal of a filter is to separate particles of different sizes from the material flow. The goal of an industrial filter is to remove potentially harmful substances from machines, equipment or vehicles. This filtration prevents any hazardous foreign contaminants from harming the workers.

Types of Filters
California gold miners in 1849 used a type of filter to strain the gold from the sand in the streams and rivers. Warehouse filters might be used to remove imperfect materials to create a higher quality finished product. Here are the primary industrial filter types:
– Air
– Bag
– Cartridge
– Gas
– Hydraulic
– Panel
– Strainer

The high efficiency particulate air (HEPA) filter uses a mesh membrane to remove dust, bacteria and debris particles. Bag filters might be used to remove contaminants of a certain size from a medium. The cartridge is flat or cylindrical and removes sediment from liquids.

Gas scrubbers are used on dry or wet gaseous streams. Hydraulic filters might be used for oil- or water-based liquids. Air conditioners use panel filters. Sinks use strainers.

Are Bag Filters Effective?
Scientists understand that during chemical processes, certain solids, liquids or gases will be emitted. In many cases, scientists even know the exact chemical content of such emissions. Bag filters can be used to remove large solids from liquids or harmful airborne contaminants from liquids or gases.

During bag filtration, the gas or liquid flows through the filtering membrane. Larger harmful particles become trapped and stuck in the bag. The bag can then be removed from the machine, cleaned or tossed to get rid of the harmful contaminants.

The bag filter comes in different sizes, shapes and micron ratings (what size particulate it traps). Thus, if you want to improve your workplace, determine which hazardous air contaminants you want to trap and purchase the bag filter with a micro rating for that hazard.

Choose the right type of filter to deal with the harmful contaminants at your work site. Stay ahead of the game, by using an air pollution control device to improve your factory indoor air quality.
