Φ 140 × 300 air filter element

Features Parameters Related

The Φ 140 × 300 Filter Element is a universal filter element identified by size as the core

The characteristics of the Φ 140 × 300 filter element are mainly reflected in terms of size, adaptability, and functionality, as follows:

1. Strong structural adaptability: With an outer diameter of Φ 140mm and a length of 300mm, it can accurately match equipment with corresponding installation chambers, such as some hydraulic systems, air compressors, small water treatment equipment, etc. It can directly replace old filter elements of the same size without the need to modify the equipment structure and is easy to install.

2. Stable filtering function foundation: As a filtering element, regardless of the type of filter material used (glass fiber, stainless steel mesh, etc.), it has the basic function of intercepting solid particles and impurities, which can protect downstream precision components (such as hydraulic valves, engine fuel injectors), maintain system cleanliness, and delay equipment wear.

3. Flexible customization of materials: Glass fiber (high-precision oil filtration), stainless steel (corrosion-resistant, high-temperature resistant, suitable for harsh working conditions), paper (low-cost, suitable for low precision, low-pressure scenarios) and other filter materials can be flexibly selected according to application scenarios (hydraulic oil, air, water filtration, etc.) to meet different media, temperature, and pressure requirements.

4. Coexistence of universality and limitations: Due to the universal size, equipment of the same size standard can be interchanged, but key performance such as filtration accuracy, pollutant holding capacity, and pressure resistance cannot be determined solely by size. In actual use, specific parameters (such as filtration accuracy of 5 μ m/20 μ m, etc.) need to be combined to fully realize the filtration value.

Technical Parameter

It is difficult to determine the complete technical parameters of the filter element based solely on the size information of "Φ 140 × 300". The following are common possible technical parameter speculations for similar filter elements:

Filter relevant parameters

-Filtering accuracy: The common range of filtering accuracy may be between 1-100 μ m. If used for hydraulic oil filtration, the accuracy may be 3-20 μ m, and for air filtration, the accuracy may be 5-50 μ m. The specific accuracy needs to refer to the product instructions and may vary depending on the filter material (such as fiberglass, stainless steel mesh).

-Pollutant carrying capacity: It is related to the filter material area and structural design of the filter element. Generally speaking, under the same precision, the larger the filter material area, the higher the pollutant carrying capacity, which may range from a few hundred grams to several kilograms.

Flow and pressure parameters

-Rated flow rate: Under specific working pressure and filtration accuracy, the rated flow rate may be between 50-500L/min. For example, when used in small hydraulic systems, the flow rate may be between 50-150L/min. If used for large industrial fluid filtration, the flow rate may be even higher.

-Work pressure: The range of work pressure is relatively wide, such as high-pressure filter cartridges used in hydraulic systems, which may withstand pressures of 10-35MPa; Low pressure filter element used for air filtration and water filtration, with a working pressure of 0.1-1MPa.

Material and other parameters

-Filter materials: may be glass fiber (commonly used for high-precision oil filtration), stainless steel (suitable for high temperature and highly corrosive environments), paper (low-cost, used for low precision and low-pressure environments), etc.

-Sealing materials: Common ones include nitrile rubber (suitable for general hydraulic oil, air and other media, with good oil resistance), fluororubber (strong resistance to high temperature and chemical corrosion), depending on the application environment and medium type of the filter element.

-Working temperature: If the filter material is glass fiber or stainless steel, the working temperature range may be -20 ℃ -120 ℃; If it is a paper filter material, the working temperature generally does not exceed 80 ℃.
