Filter Strainer

[Hermalindo Lepicier]

Industrialstrainers and filters are designed to remove unwanted particulates from a liquid or gas. The key difference between strainers and filters are the size of the particles they remove. Strainers typically remove larger particles that are visible in a liquid or gas, while filters remove contaminants that are often so small, they cannot be seen with the naked eye.

While strainers are used to remove larger particles, filters are used to remove smaller unwanted particles from both liquids and gasses. Filters are typically used when the liquid or gas passing through the system must be free of most contaminants, even those as small as a grain of sand. Many filters are reusable, while others must be replaced periodically.

A general rule of thumb is that filters remove particles smaller than 40 microns, which are typically too small to see. Strainers, on the other hand, remove particles larger than 40 microns. Something this size would usually be visible with the naked eye. In some applications, it may be possible to use either a strainer or a filter, if the particles you wish to remove are between 38 and 177 microns.

Another key difference between filters and strainers is the pressure of the gas or liquid as it passes through the medium. Liquid passing through a strainer will likely not see a drop in pressure as it passes through. If there is a drop in pressure, however, it might indicate that the strainer needs to be cleaned or removed. On the contrary, liquid or gas passing through a filter will likely experience a noticeable drop in pressure.

If your system cannot manage frequent shut downs for cleaning and maintenance, you may want to consider a duplex housing. This configuration will allow you to remove and clean, or replace one filter or strainer while the other can continue to function. In a single configuration, the entire system will need to be turned off and depressurized before maintenance can be done.

Flow rate and pressure is another key factor when choosing a strainer or filter. Because filters do impact both flow rate and pressure at higher rates than strainers, those using high flow systems may face more setbacks with filters. However, high flow liquid filtration systems exist and may be an option for your system. To learn more, read our post on the advantages to high flow liquid filtration.

Streamline in-line filters and strainers promote product quality and sanitation and help protect processing equipment. It is a good fit for equipment including homogenizers, meters, spray nozzles, needle valves, and pumps. The free-flow design and stainless steel construction provides optimum sanitation and corrosion resistance. It is compatible with a variety of woven and non-woven filtering media.

As a strainer, the Streamline can be furnished with a single screen for straining large particles. To remove finer particles, it can be furnished with a back-up tube and over screen with small perforations.

The lightweight design is sanitary and is approved for use in USDA meat and poultry inspected plants.The Streamline is available in two lengths to provide optimum filtration area for the application. The Streamline is furnished with a single screen for straining large particles or with a backup tube and over screen with small perforations for removing finer particles. Model SMS Strainers or FMS filters feature convenient side-entry and a pullout top for easy servicing, without the need for removal from the process line.

There are some similarities between filters (such as cartridge and bag) and strainers (such as this one), so, unsurprisingly, the two are sometimes misunderstood. Both, for example, are intended to remove particulate from a gas or liquid. Furthermore, both strainers and filters can be designed in a duplex configuration, enabling one strainer or filter to be washed while the other remains functioning. While the two share many characteristics, strainers and filters are not interchangeable.

Micron and mesh are typical measuring units that are interchangeable. A mesh of 35 is about similar to a micron of 500. Mesh is utilized for straining and micron is used as a measuring unit for filtering.

Filters eliminate particles smaller than or less than 40 microns, which are often too tiny to be seen. on the other hand, Strainers, remove particles that are bigger than 40 microns in size. Normally, something of this size would be apparent to the human eye. If the particulate to be removed ranges between 38 and 177 microns, you might well be able to utilize either a filter or a strainer in some situations.

The pressure of the fluid or gas as it travels through the media is another important distinction between strainers and filters. A liquid flowing through a strainer will most likely not experience a reduction in pressure while it does so. A decline in pressure, on the other hand, may signal that the strainer requires to be cleaned or replaced. A liquid or gas moving through a filter, on the other hand, will most likely suffer a considerable reduction in pressure.

A strainer aims to remove bigger, undesirable particulate from a fluid, particularly to safeguard downstream machinery such as pumps. Strainers come in a range of forms and sizes dependent on their use, but one aspect is critical: they are intended for simple removal and cleansing. To guarantee optimal operation, quick cleaning necessitates minimum downtime for the apparatus.

Filters remove tiny undesired particles from gases and liquids, whilst strainers are often used to separate bigger particles. Filters are commonly utilized when the fluid or gas moving through the network must be devoid of most pollutants, including those as tiny as specks of sand. Many filters are reusable, while others must be changed on a regular basis.

In general, the fundamental distinction between the 2 units is that a sieve will capture debris while allowing the desired liquid to pass through, but a filter will capture the desirable material/items while allowing the waste fluid or substance to pass through. Another distinction is that a strainer comprises numerous screens that, once used, may be cleaned and reused. Filters have a screen that can only be used once before becoming clogged, at which point the screen must be replaced. Filter screens are never used again.

Another important consideration when selecting a filter or strainer is flowing velocity and pressure. Because filters have a greater influence on pressure and flow rate than strainers, customers utilizing high flow systems may experience more problems with filters. High-flow liquid filtration operations, on the other hand, exist and may be an alternative for your setup.

Why should you be concerned with pressure drop? As the strainer or filter fills, the differential pressure increases because the filtered particles lower the surface area of the filter. When the strain to overcome this becomes too severe, the intended flow thru the filter is jeopardized. The regularity with which the filter must be emptied is determined by the quantity of filter contact area and the volume of particles being filtered. If the pressure drop is too much, to begin with, the filter will rapidly approach a tipping point and clog.

Particles Understanding the kind and particle size that is filtered helps you to determine the appropriate micron filter or strainer size. Well, water, for example, comprises inorganic particles such as sand, whereas pond groundwater contains primarily organic things such as phytoplankton and leaves. In general, inorganic components require a narrower screen to catch silt and sand that would otherwise go through the most. Water is only one of many examples. Viscous goods such as paper coverings, paints, honey syrup, and everything else in between can also be filtered.

Surface filters must be cleaned and maintained regularly. This is since they undertake incredibly sensitive tasks that need the utmost care. Depth filters do not need as much upkeep as surface filters. Because of their total size and storage capacity, they do necessitate additional labor.

To ensure quality certified depth filters function effectively, clogged pieces must be replaced regularly. A surface filter unlike depth filters needs more cleaning activities than component replacement operations.

Servicing. If indeed the line is unable to shut down, a duplex strainer might well be required to switch the flow whenever a basket becomes full. A self-cleaning filter might well be appropriate for some operations, reducing the need to stop flowing or disassemble pipework.

When evaluating the size and form of the particles to be removed, select a mesh that is somewhat smaller than what is required. This will aid in the removal of broken-down pollutants as well as those with the potential to deform and slip through the mesh. It may appear to make sense to select a strainer or filter with a much finer mesh than is required, but the finer the strainer or filter, the more frequently it must be cleaned.

Size of the pipe The filter or strainers should be the same size as the current pipe. Furthermore, pipe layout (horizontal or vertical pipework, or right angle) influences which form of industrial filtration is optimal.
