A hydraulic filter is a device that is used to remove contaminants, such as dirt, debris, and air bubbles, from hydraulic fluid in a hydraulic system. Hydraulic systems are used in a variety of industrial and commercial applications, including construction equipment, manufacturing machinery, and transportation vehicles. The hydraulic fluid is responsible for transmitting power and energy within the system, and it is essential that it is kept clean and free of contaminants.

The primary function of a hydraulic filter is to protect the equipment and components in the hydraulic system from damage caused by contaminants. When contaminants are present in the fluid, they can cause wear and tear on the system, leading to costly repairs and downtime. By regularly replacing and maintaining hydraulic filters, the health of the equipment can be maintained and its lifespan extended.

Regular hydraulic filter replacement is important because the filter element becomes clogged with contaminants over time, which can reduce its effectiveness and impact the performance of the system. As the filter becomes clogged, it becomes more difficult for the fluid to pass through it, which can lead to increased pressure and reduced flow rate. This can lead to reduced efficiency and performance of the equipment, as well as increased wear and tear on the system.

In addition, contaminants that are trapped in the filter element can break loose and enter the system, which can cause damage to the equipment and components. This can lead to costly repairs and downtime. By regularly replacing the filter, these contaminants can be removed from the system and the risk of equipment damage can be minimized.

Overall, regular hydraulic filter replacement is important to ensure that the filter is functioning properly and the equipment is operating at its optimal level of performance. By following the manufacturer’s recommendations for filter replacement intervals and regularly inspecting the filter element, it is possible to extend the lifespan of the equipment and minimize the risk of costly repairs and downtime. Generally, the filter should be changed when the differential pressure (PSID) reaches or exceeds 25 PSID.

A micron, also known as a micrometer, is a unit of length that is equal to one millionth of a meter. It is commonly used to measure the size of particles in liquid filtration systems.

In the context of liquid filtration, the size of the particles being removed is an important consideration, as smaller particles are more difficult to filter out than larger particles. Filters are typically rated in terms of the size of particles that they can effectively remove, with smaller values indicating a higher level of filtration. For example, a filter with a rating of 1 micron is capable of removing particles that are 1 micron in size or larger, while a filter with a rating of 0.1 micron is capable of removing particles that are 0.1 micron in size or larger.

The beta ratio, also known as the beta value, is a measure of the efficiency of a filter at removing particles of a particular size. It is typically used to compare the performance of different filters or filter media and is often used in the selection and design of liquid filtration systems.

The beta ratio is calculated by dividing the number of particles of a particular size that are removed by a filter by the total number of particles of that size that are present in the fluid being filtered. For example, if a filter is able to remove 90% of the particles that are 1 micron in size from a fluid, its beta ratio for 1 micron particles would be 90.

The beta ratio can be used to compare the performance of different filters or filter media at removing particles of a particular size. A filter with a higher beta ratio is more efficient at removing particles of that size than a filter with a lower beta ratio.

Microglass, also known as microfiberglass, is a type of synthetic fiber that is commonly used in liquid filtration systems due to its high efficiency and good filtration properties. Microglass is made from extremely fine fibers of glass that are tightly woven together to form a filter media.

There are several reasons why microglass is well-suited for use in liquid filtration:

-Microglass has a high dirt holding capacity, which means it is able to filter a large volume of fluid before becoming clogged and needing to be replaced.

-Microglass has a high efficiency at removing small particles, making it suitable for use in high-purity filtration applications.

-Microglass is resistant to chemicals and corrosion, which makes it suitable for use in a wide range of filtration applications.

-Microglass is durable and has a long lifespan, which makes it a cost-effective choice for many filtration systems.

Overall, microglass is a popular choice for liquid filtration due to its high efficiency, good filtration properties, and durability.

When contaminated air enters the top of the breather, it passes through 3-micron absolute layered filter media, preventing solid particles from entering the breather and causing undue wear to your equipment surfaces. Filtered air passes through a bed of specially formulated silica gel, which removes harmful moisture from the air. The silica beads also work to attract moisture from inside the equipment reservoir during service or shut-down, keeping the equipment dry.
