How do Air Handling Units work?
Air handling units, commonly referred to as AHUs, are typically found in medium to large commercial and industrial buildings. They are often situated in the basement, on the roof, or on various floors of a building. AHUs are designed to serve specific areas or zones within a building, such as the east side, floors 1-10, or even a particular space like the restrooms. It is common to have multiple AHUs throughout a building to efficiently distribute air. In older high-rise buildings, a single large AHU locate
primary filters and secondary filters Air Filtration in AHU`s
Inside an AHU we will typically find two sets of filters. The first set is known as the primary filters and we also then have the secondary filters. These both have different functions in an air handling unit. The primary filters are usually panel filters. These are there to catch the dust. They`re typically made with a pleated design which increases the surface area and allows it to catch much more dust and last a bit longer than if it were just a flat sheet. They`re usually made from a synthetic material with a cardboard outer frame and they`re hel
How to properly maintain the microporous filter
Microporous filter is a new type of high precision filter equipment recently developed, microporous filter can be divided into coarse filter microporous filter and fine filter microporous filter, the maintenance of these two microporous filters is roughly the same. The important thing is the maintenance of the filter element, the filter element is equivalent to a person's heart, it is the "heart" of the microporous filter, the heart belongs to the wearing part, but also needs special protection, first of all, the microporous filter should be cleaned after a period of time, because after a peri
Teach you to identify the quality of the filter element
Filters are usually divided into a class of hydraulic accessories, it seems that the degree of attention is not high, in many people's eyes, even without the filter attachment, many parts of the equipment can operate freely, without pressure. It is true that the operation of pumps, cylinders and valves does not depend on filters. However, the operating life of these pumps, cylinders and valves is closely related to its working medium, in other words, the quality of the oil is related to the operation of the equipment. It can be seen that filters cannot be completely ignored. The
Analysis of common misunderstandings in daily maintenance of filters
Filters are widely used in the industrial industry and are also the main equipment used for system control of pollution. The daily maintenance of the filter is very important, the performance of the machine is important, but in order to maintain the superior performance of the machine, it is inseparable from the usual careful maintenance and maintenance. Therefore, in order to make the oil filter can have good working efficiency and ideal working life, it is not only necessary to maintain frequently, but also to maintain in the right way. However, many people still have many misunderstandings
Filter for water purification unit

Flushing filter installation common problems
In general, the following points should be noted in the case of installing backwash filters: 1. The filter model should be used in line with the installation of the pipeline, when the total flow of the filter cannot meet the pipeline standards, two (or several) filters can be installed, or the side filter solution. 2. The filter should be installed in the area of the system to protect as much as possible, and the channel low voltage affects the use, so the backwash filter should also be installed in the area close to the bad mood. 3. The filter shou
PP cotton filter want to extend the service life should do
In industrial production filtration, people often say that PP cotton filter refers to melt-blown pp filter, which is a finished product formed by heating melting, spinning, traction belt, and molding processing, and the shape is tubular. It is often used in the liquid filtration of organic solvents, architectural coatings, dishwashing agents, drinks, drinks and other fields. However, every product has a certain service life. In that case, what should be done to extend the service life of P cotton filter? In general, the PP cotton filter must be cleaned regularly if it wants to be used f
The role of air filter element
The engine in the working process to suck in a lot of air, if the air is not filtered clear, the suspended dust in the air is sucked into the cylinder, it will accelerate the piston group and cylinder wear. Larger particles entering between the piston and the cylinder will cause serious cylinder pulling phenomenon, which is particularly serious in dry and sandy working environments. The air filter is installed in the front of the carburetor or the intake pipe to filter the dust and sand in the air to ensure that sufficient and clean air is entered into the cylinder.
