Compressed Air Dryer Filter And Accessories

It removes aerosols of liquids such as water and oil by coalescing. Coalescing is the process of capturing smaller droplets along a filtration medium. This is until they combine into larger droplets.

The droplets continue to coalesce until their weight is large enough. 마지막으로, under gravity, they fall to the bottom of the air compressor water separator filter. Then they are discharged by the drainer.

Filter life and dirt-holding capacity are limited. 그러므로, compressed air quality cannot be guaranteed when its life expires. 대개, the replacement cycle of our filter element is 8000 시간.

게다가, it is not only to ensure air quality but also to consider pressure loss and energy consumption. The additional power of the air compressor must compensate for the pressure loss of the filtration system. 결과적으로, the power consumption of the compressor increases. 결국, operating costs and expenses will rise. Now take two examples for comparison.

Example:

Electricity fee: 0.07USD/kWh,

For every 100SCFM air consumption, the pressure loss will increase by 1PSIG,

Finally annual increase in electricity bills due to pressure loss: 67 USD.

In conclusion, in case 2, the filter element was used twice as long as in case 1. 하지만, the total cost increased by $940 due to a bigger pressure loss. So much more than the cost of replacing the filter element ($400). 따라서, we must exchange the air compressor water separator filter element in time.

첫째로, this gauge is not a service indicator for the air compressor water separator. 게다가, it is also not an indicator of air quality either. It just shows the differential pressure roughly. Or indicate whether the filter element is blocking in advance.

Filter fibers gradually become brittle during use. So even a tiny hole can cause the filter media to break. Then contaminants will enter the downstream compressed air system without filtration.

In this case, the pressure difference between the front and rear of the compressed air filter is not large. So the pointer will always be in the green area.

So the filter element will not be replaced in time. And when we find there are already a lot of pollutants downstream.

일반적으로, filters only remove solid and liquid particles. 하지만, water vapor and oil vapor can still pass the filter material. 그러므로, the mechanical filter cannot filter them out. 물론, except for the activated carbon compressed air filter.

To fundamentally remove water vapor and oil vapor, only use a dryer to lower the dew point.

Many people mistakenly believe that it is enough to choose a high-precision filter. This saves costs. This is not correct.

Air quality depends on the accuracy of a single filter. But without the pretreatment protection of the pre-stage filter, the high-precision filter element will be blocked soon due to excessive load.

So it will speed up the replacement frequency of the filter element. 마지막으로, it will increase the production cost in a disguised form.

In some industrial situations, there is often inhalation of dangerous air, liquids, or particles. To protect our workers, filtering is necessary.

예를 들어, carbon monoxide is a toxic gas. If without filtration, it will be a hazard to our workers. A breathable compressed air dryer filter can remove these harmful gases. It can convert carbon monoxide into carbon dioxide.

Compressed air has more and more wide applications in industry. 동시에, the quality requirements for compressed air are getting higher and higher.

The air will contain many impurities, such as bacteria and dust. Some industries require it to be sterile-filtered. 그렇지 않으면, it will affect the production of the enterprise. It will also increase the consumption of resources and funds.

We can produce quick-fit stainless steel compressed air sterilizing filters. These sanitary filters are popular in industries such as beer, dairy, pharmaceutical, 음료, 음식, 등.

Unlike general air compressor water separator filters, its housing is 304 스테인레스 스틸. 게다가, the filter element is not a filter paper material but PTFE.

It sterilizes the air with high-temperature steam. The sterilization efficiency can reach 100%. The time is about 20 에게 30 minutes.

Filtration accuracy refers to the max size of particles that the element can block. The higher the filtration precision, the smaller the particle size blocked.

But it is also easier to be blocked by particles with larger sizes. 그러므로, using high-precision filters regardless of the occasion cannot guarantee improving filtration efficiency. 게다가, it will affect the service life.

The largest contaminant in compressed air is water. Water includes liquid water and moisture vapor.

Air compressor water separator filter can remove liquid water. But it cannot remove moisture vapor. 게다가, as the temperature decreases, the latter condenses into liquid water.

So this brings great trouble to the downstream pneumatic equipment. Water vapor can only be removed with the air compressor dryer. 그러므로, a compressed air filter cannot replace it.

Refrigerant air dryer has rated requirements for inlet air temperature and pressure. 게다가, the refrigerant dryer also requires that there is no liquid water in the air. So it can avoid increasing the refrigeration load.

This requires a pre-filter or air-water separator. The requirements for air compressor air dryer filter precision are not very high. Our pre-filters have a filtration precision of 1.0 μm.

The dust particles in the air do not significantly affect the cooling capacity. Water vapor requires the involvement of particles in the condensation process. 게다가, the condensation water with larger sizes is easier to separate than the smaller ones. 마지막으로, all these solid particles will be discharged with the condensate.

This reflects that the refrigeration air dryer itself has a self-cleaning function. So there is no point in having an air compressor water separator filter with too high a precision before the refrigerated dryer.

첫째로, desiccant dryers have higher filter requirements than refrigerant dryers. Because the adsorbent is very sensitive to oil. The oil vapor content should be under 0.1mg/m³. 그렇지 않으면, it will influence the water-removal effect of the adsorbent. 게다가, it will shorten the lifetime.

둘째, the adsorption dryer should have a dust-removal compressed air filter. The filtration precision is 0.01 미크론. Because of the constant friction between the adsorbent particles, it will generate dust. Then this dust will enter the downstream air pipe. 결국, it will cause secondary air pollution. So there must be a high-precision filter.

Pressure drop is an important indicator of an air compressor water separator. 게다가, it can also measure the working life of a filter element.

첫째로, the filter element has a tiny initial pressure drop. But with time accumulation, the pressure drop will tend to rise.

When reaching a certain value, the lifetime of the filter element ends. 이때, it should replace the element.

To observe in time, we should add a differential pressure gauge. It can show the pressure drop of the compressed air filter at any time.

The housing is an important part of the air compressor water separator. It withstands the full internal pressure. 그러므로, the filter housing must have high tensile and compressive strength.

게다가, the working conditions of air compressor dryer filters are generally harsh. The inner wall of the filter housing is often in contact with the oil-water mixture. 따라서, it should have an anti-rust and anti-corrosion ability.

They are different. The compressor filters are used for the screw air compressor. And it includes there kinds of filters. That is the intake air filter, 오일 필터, and air-oil separator.

But the compressed air dryer filter belongs to the air treatment equipment. And we usually install them onto the main pipe. These filters work with dryers to purify compressed air. Because the air compressor water separator filter can remove dust, moisture, and oil vapors.

첫째로, activated carbon has a huge surface area. So it has a strong physical adsorption ability. And it can adsorb chemical impurities such as organic vapors, sulfur, carbon dioxide, and various micro-organisms.

그러므로, it is widely used for oil removal and deodorization applications. Or we also use it as a sterilization filter. Oil vapors can easily pass through coalescing filters. So we need this carbon filter.

The main function of an activated carbon compressed air filter is to remove oil and hydrocarbon vapors. They are most commonly used where removing taste or odor is critical. 예를 들어, food processing and pharmaceuticals.

Since moist air reduces activated carbon adsorption, generally install it after the desiccant dryer. 게다가, activated carbon filters can’t remove liquid oils or sols. So poor maintenance or no pre-filter will accelerate its performance failure.

There is a float drainage system in the automatic drain. When the pressure is low, the drain is closed. So it will not carry out drainage work at this time.

하지만, when the buoyancy and pressure are in balance, it starts to drain in drips. When the buoyancy force is greater, the drain port will open. Then it carries out drainage. So it works cyclically according to the buoyancy force.

The pre-filter is also namely the rough/coarse filter. In most cases, it is used at the front end of the pipeline. 그러므로, we call it the compressed air pre-filter.

The main function is preliminary compressed air filtering, such as oil, moisture, 먼지, and rust. It can protect the fine filters downstream. To prevent large impurities from damaging the precision filter.

반대로, the post-filter mainly refers to high-precision filters. Its filtration accuracy will be much higher. 게다가, we usually install it at the back end of the pipeline.

There are many reasons for air leakage, such as the automatic drain or drain valve leaking, poor closure of the filter end cap, or filter housing leakage. So the troubleshooting is as follows:

1. Close the drainer well; clean up impurities in time; or replace a new automatic drain;
2. Contact the compressed air filter manufacturer to exchange a new end cap or housing.
