An industrial filter is one of the widely used equipment in various industries, applied for separating different elements. These devices are used to separate suspended solid particles in fluids such as liquids and gases. In general, industrial filters operate in two ways to purify fluids.

Some filters perform purification when the fluid is flowing and being discharged, while others carry out the process once the flow stops. Each type of filter has its own application in specific industries. Knowing the uses of filters in different industries can be a good guide in choosing the best filter.

Agricultural Industry Filter

Water used in the agricultural industry usually comes from wells, springs, and rivers, and therefore may contain a large amount of sand, minerals, and fine particles. To use this water in farming and gardening, these impurities must be removed; otherwise, the risk of clogging and corrosion of irrigation pipes will increase.

Since modern agriculture uses pressurized or drip irrigation, the use of industrial filters for water purification is essential. The filter is installed at the wellhead and removes suspended particles from the water at the first stage. This process increases the lifespan of pumps and reduces maintenance costs.

Medical Industry Filter

Different types of filters are used in the medical industry, but the most common is the air filter in hospitals. Airflow is the main medium for transmitting viruses and bacteria. Since hospitals require completely clean air, using filters to purify the air is essential.

Another commonly used medical filter is the HME filter. The air patients breathe must be warm and humid; otherwise, it can cause thick, dry, and bloody mucus, blocking the airways. This makes breathing difficult and leaves the respiratory system vulnerable to infections and other complications.

HME filters (Heat and Moisture Exchangers) warm and humidify the air entering the lungs of patients who cannot breathe naturally. This prevents dry airways, bacterial accumulation, infections, and other respiratory issues.

Petrochemical Industry Filter

Another application of industrial filters is in the petrochemical industry. Filtration in petrochemical processes includes filtration of fluid injected into oil wells, purification of recycled process water, filtration in polymerization, filtration of cooling fluids, jet fuel and oil filtration, catalyst recovery, filtration of raw and final chemicals, as well as slurry filtration.

Filters used in the gas, oil, and petrochemical industries protect essential equipment such as heat exchangers, pumps, and valves. This reduces maintenance and repair costs. Moreover, using industrial filters improves oil well output, lowers operational and energy costs, and reduces pipeline corrosion.

Road Construction Industry Filter

Filters are among the most important and essential equipment in the road construction industry. Different types of filters are used in various road construction machinery. Below are some of the essential filters used in construction equipment.
