What is High Temperature Filter

The filter media used in high temp filters can be distinguished by structure, composition and operational behavior. Initially developed for electric power generation, this technology is now receiving considerable attention from process industries. With the introduction of reliable, high temp filtration, there has been increasing interest in this type of industrial air filtration across several industries.

What are the characteristics of a high-temperature filter

Although filters are often used in our daily life, if we encounter a high-temperature working environment, the filters we often use in our lives will be overloaded high-temperature environment and cause damage, so there will be high-temperature resistant filters. Appear. High-temperature resistant filters are used in high-temperature antibacterial tunnels, high-temperature drying rooms, laboratories, pharmaceutical factories, and other fields. It seems that the use of high-temperature-resistant filters is still very common. However, its classification is based on the efficiency of the work. According to work efficiency, the high-temperature filter can be divided into primary and high-efficiency filters. There are fewer intermediate-efficiency links in the middle than in other filters. Moreover, the high-temperature resistant filter uses special synthetic fibers or glass fibers to improve the efficiency and accuracy of filtration.

The high-temperature filter itself has very good durability. When it uses ultra-fine glass fiber as the filter material, the improved filtration effect and filtration efficiency are very obvious. Other parts of its materials will also choose to use aluminum foil boards or offset paper for segmentation, which protects the filter material on a certain basis and reduces the risk of use. The outer frame of the high-temperature resistant filter will be made of galvanized or other stainless steel materials, which can ensure the normal use of the high-temperature resistant filter, and also improve the strength of the high-temperature resistant filter, which increases the filtering area to a certain extent.

The main feature of the high-temperature resistant filter is that it is resistant to high temperatures, and its high-temperature tolerance range can reach 350 degrees. The high-temperature filter can continue to operate normally in an environment of 250 degrees, and there is no leakage problem like other filters. This is its biggest feature. High-temperature filters can also be subdivided into three types: flat, HTR, and folded.

The flat type is the material of glass factory long fiber. The filter material is mainly laid in the filter, and both sides are made of molybdenum metal mesh and square mesh. The temperature that can withstand is 400–450 Spend.
Folding type, this high-temperature resistant filter has good strength, the filter material is not easy to be blown and break, and it can be used normally in the environment of strong wind. The temperature of the folded high-temperature filter can reach 250–310 degrees.

What Is The Use Of High Temperature Air Filter

In the air filter industry, filters are divided into high-efficiency, medium-efficiency,initial-efficiency,activatedcarbon,high-temperature resistance, etc.

Let’s take a look at the advantages ofhigh temperature resistant filters. The filtering accuracy and filtration efficiency of high temperature resistant air filters are very good. In many current production environments, the requirements for environmental cleanliness are relatively high. At this time, high-precision filtration equipment is required to perform the corresponding filtration work and provide clean air for these production sites. At the same time, the high temperature filter can also adapt to some low-precision filtration work, and is widely used in aerospace, electronics, semiconductors, biopharmaceuticals, hospitals, food production, wafers and other occasions that require high cleanliness environments. It is mainly used in the end of air conditioning and ventilation systems, purification ovens, food baking equipment, clean baking rooms, high temperature sterilization equipment, high temperature coating lines and other places. Because of its high temperature resistance, it can complete the filtration with high quality and quantity in high temperature environment. It can also effectively avoid damage to the quality of the equipment caused by the high temperature environment, so that the equipment can perform filtration work stably for a long time, so that users can do production control and cost control.

There are some things worth noting when we use high temperature filters. If the work intensity is relatively large, in order to prolong the service life of the high temperature filter and reduce the workload of the high temperature air filter when using the high temperature filter, the pre-filtration environment can be increased. And different high temperature filters have a limit on the upper limit of the temperature they can withstand. Pay attention to the upper limit, and the temperature cannot exceed the upper limit, otherwise the quality of the high temperature filter will be damaged. To better use the high temperature filter, it is necessary to have a certain understanding of the high temperature filter. At the same time, in order to ensure that the high temperature filter will not be damaged in the process of use, it is also necessary to pay attention to some precautions.

If you want to know about air filters, you can consult Shanghai Industrial Co., Ltd. They are anair filter manufacturerintegrating R&D, production and sales, dedicated to coating electronic plants, semiconductors, LCD screens, biopharmaceuticals, food, petrochemical industries, clean rooms, hospitals, rail transit, and automobiles , commercial and civil construction industries provide the air purification solutions and air filter products they need.

Basic Maintenance Tips For High Temperature Air Filters

When it comes to high temperature air filters, I think people living in the 21st century may know it better than me. You may have heard the termhigh temperature resistant air filters. A kind of purification equipment that can give full play to its performance under the premise of Its main use is in equipment such as ultra-clean ovens and equipment and systems that require high temperature air purification.

Each product of high temperature resistant air filter is put on the market after strict testing, so it can be used with confidence and safety. The components of the high temperature resistant air filter are very simple, that is, the ultra-fine glass fiber paper is used as the filter material, the aluminum foil is used as the separator, the stainless steel frame is used as the frame and the imported high temperature resistant sealant is sealed and assembled. Regardless of any filtering equipment, how should we maintain the high temperature air filter

For the hydraulic pressure of high temperature resistant air filter, it is enough to replace the hydraulic oil once a year. When replacing, the hydraulic system should be completely cleaned.

Under normal circumstances, the working pressure of the high temperature resistant air filter hydraulic station is less than the maximum working pressure of the oil cylinder, but the minimum can not be lower than the allowable value of the filter pressure.

Generally speaking, the high temperature resistant air filter mechanically presses the transmission parts, and the gear box must be lubricated with enough lubricating oil to ensure its good function.

The last thing that needs to be added is some issues that should be paid attention to in the use of high temperature air filters.

Under normal circumstances, the glue curing time of the high temperature filter is within one week. Since the organic silica gel and inorganic glue used in the high temperature air filter are cured from the surface in the curing process, especially the thicker the glue injection height, the harder it is to cure. Just imagine that if the incompletely cured high-temperature high-efficiency filter is directly loaded into the high-temperature equipment for normal use, the high-temperature glue will crack and the glue will detach from the outer frame.

How to choose a high temperature resistant filter

The biggest feature of the high temperature filter is that it can work continuously in an environment with a temperature of more than 300 degrees, ensuring stable and long-lasting work of the equipment. Moreover, the high temperature filter has a large dust holding capacity, which is several times the filtration performance of the traditional filter. The high temperature resistant filter has been continuously improved, and the quality of the equipment itself is very good.

It is light, which greatly facilitates the installation, and is also more convenient in the daily use process. It is worth noting that the high-temperature-resistant filter requires regular maintenance. Due to long-term high-temperature operation, it will also cause a certain amount of wear on the equipment itself. Therefore, only by doing regular maintenance can the filtration performance of the high temperature filter be better utilized. Under normal circumstances, it is necessary to conduct an equipment inspection every six months.

The price of high-temperature-resistant filters is also different according to different material models. Under normal circumstances, the price ranges from tens to hundreds of yuan. The high temperature resistant filter needs to do routine maintenance during use to maximize the potential of the equipment. It is very important that the filter is used for the first time after the filter has risen to a certain temperature and cooled for two hours before continuing to use. Yes, in the face of many high-temperature resistant filter manufacturers in the market, how should customers choose their own products? First of all, we must start from product quality considerations. Only good quality can be used for a longer time, and the probability of problems will be relatively small. Secondly, we must consider the environment in which we use ourselves. The use environment affects the working efficiency of the high temperature filter to a certain extent. The considerations include the temperature and humidity of the environment, etc.

In the later use process, it is necessary to regularly check whether the filter is worn out The higher the higher, I believe that in the future, the high temperature filter will undergo continuous reform and innovation to provide people with better services and do our part in the cause of environmental protection.

FAQ

Q: What is the effect of high temperature on the performance of filter fabric?

A: In the samples charged at 70°C–110°C, the QF of the sample treated at 80°C was the largest, the corresponding filtration efficiency was 98.35%, and the filtration resistance was 38.7 Pa. We find that the filtration performance of fabric charged at room temperature was the best in all samples.

Q: Is any other maintenance required for air filters and purifiers?

A: Changing the air filter is the most common maintenance you'll need to do to your purifier, but there are some things you can do to maintain quality performance. Depending on the model you have, you may need to replace parts that break or become worn out. For example, if your filter uses UV technology, the bulb may need to be replaced at some point.

Q: How do I know when it's time to change a filter?

A: For most air purifiers, there is a filter replacement indicator that gives you an alert when it is time to check or change the filter. This indicator gives you greater confidence because you know you are not using old, dirty filters, nor are you spending too much money replacing filters when it's not needed.

Q: What can I expect to spend on new filters?

A: As we've seen, filters can come in a wide variety of styles and sizes. As such, there is also a wide variety of prices. You can reasonably expect to spend less on “pre-filters” and more on the main filters.

Q: Why do I need a pre-filter?

A: Pre-filters are designed to keep out larger particles of street debris such as rubber, dirt and sand from getting into and clogging the pleats of air filter elements. Premature clogging of an air filter will result in loss of horsepower and an increase in service intervals. Our pre-filters are uniquely designed to protect your engine and the performance air filter investment without sacrificing airflow or horsepower. Particles as small as .005" are filtered out extending filter life. Even in harsh conditions, including heavy moisture, a pre-filter will enhance your filters ability to continue flowing the necessary air required for maximum performance while reducing the possibility of water ingestion into the engine. Proper use of a pre-filter will save money on filter cleanings or replacements and extend engine life. Some customers report increased fuel efficiency.

Q: Where is the ventilation filter?

A: The air filter is typically located at the point where the return duct enters the air handler. Larger houses often have more than one HVAC system. Each system will typically have at least one air filter. Therefore, your home may have filters located at the air handler AND in the returns.

Q: Do vent filters reduce dust?

A: One of the simplest ways to keep the dust levels in your home as low as possible is to regularly replace your HVAC air filters. Your air filter does just that–filters out dirt, dander, and dead skin to keep your home virtually dust free.

Q: What is the difference between ventilation and filtration?

A: Ventilation systems are designed to filter larger, less hazardous particulate. Air filtration systems are built to extract fumes, smoke, mist, and other submicron-sized air contaminants.

Q: Are air filters washable?

A: Yes, some kinds of filters are washable! That means that instead of getting rid of your air filter when its three months are up, you can wash the dust and debris off and place the filter back into your HVAC system. Not all filters are reusable, so make sure you have a washable filter before running it underwater.

Q: Do vent filters reduce air flow?

A: While the benefits are certainly noticeable and important, it's also a good idea to consider the drawbacks in adding filters to your vents. After adding an air filter to your vents, you'll likely notice decreased airflow.

Q: How long can an HVAC filter last?

A: A one inch furnace filter should be changed out every one to three months. A three to four-inch filter can last for six to nine months. If you have a thick five to six-inch filter, it can last from nine to twelve months.

Q: How to check HVAC filter?

A: You can tell if you need to clean or replace the air filter by removing it from its chamber and holding it up to the light. If light can easily pass through the filter and it's semi-transparent, leave it in. If it's hard for light to pass through and it's visibly dirty, change the filter.

Q: How are HVAC filters rated?

A: MERV ratings are from 1-16, and filters with higher MERV ratings trap small particles more effectively than filters with lower MERV ratings. In general, filters with a rating of MERV 16 or below are considered to be HVAC-system-grade filters for residential, commercial and general hospital use.

Q: When to replace furnace filter?

A: The standard recommendation is to replace furnace filters at least once every 90 days. Keep in mind, this is a general recommendation. There are a few factors that can shorten or extend the time between furnace filter replacement intervals.
