How does FONHO Fuel Water Separator Works?
Oil-water separators are filters that remove both free and emulsified water from fuel. They do this by absorbing water that is sized in microns. The density of water droplets will be lower than that of the fuel, so they will fall to the bottom of the filter. However, a lighter fuel will rise through the filter to the next stage, where they are separated from the remaining fuel.
Oil-water separators remove free water and emulsified water
Fuel-water separators are used to remove free water and emulsified moisture from diesel fuel. These units can be installed on either the tank or the frame rail of a truck. The hydro-carbon series is particularly useful for this purpose, as it removes both free water and muck. In addition, its patented technology coalesces fine droplets of water and separates them from the product stream.
The SAE J1839 standard defines emulsified water as coarse liquid with a mean droplet size of 180-260 microns. In this standard, the amount of undissolved water a fuel water separator removes depends on the ability of the device to remove this water. However, it is important to note that dissolved water has no detrimental effects on fuel system components.
They separate oil from water
Oil-water separators separate oil from water. As oil is lighter than water, it tends to float to the top, while the water sinks to the bottom. Water is used for other purposes, such as filtration and aeration. It then travels across a series of plates or an incline, passing through filters. A number of benefits of using fuel water separators can be gained.
These devices also prevent the discharge of oil into ships’ bilges. These devices are used for a variety of purposes, from preventing the spillage of crude oil into the water to reducing the maintenance of the vessels. The fuel water separator is an important part of a vessel’s fuel system, and it is used in various industries. Whether it is a service station, commercial kitchen, or off-shore oil platform, the use of a fuel separator can greatly reduce the amount of waste and maintenance costs.
They can absorb up to 0.5% of water
If you are concerned about the water content of your fuel, you may want to consider using a fuel water separator to help prevent this problem. Fuel water separators are designed to capture water in a collection bowl at the bottom of the filter. To inspect the water in the collection bowl, you can periodically remove the filter element. It should be changed after 300-400 hours of use.
A fuel water separator is an inexpensive way to prevent water from entering your vehicle’s fuel system. The filter is effective in removing more than 99 percent of particulates, including water. Water is denser than gas, so it sinks into the collection bowl at the bottom of the filter. FONHO fuel water separators can absorb up to 0.5% water. Fuel water separators may be used in combination with other filters and fuel filters, but they are most effective in removing both types of water from a fuel system.
They are rated in microns
The number of microns used to rate fuel filters indicates the percentage of particulates that are trapped by a particular filter. Microns are a unit of linear measurement in the metric system. They measure the distance between one point and another. The smallest particles are typically less than one micron. An absolute micron rating of 99% means that a fuel filter will capture all but one percent of particulates larger than 10 microns.
Most fuel filters will state the micron rating of their individual filters. This rating identifies the filter’s capacity to capture particles of varying sizes. For example, a filter rated at 20 microns will capture approximately ninety percent of particles 20 microns in size or larger. The higher the micron rating, the greater the efficiency of removal. Microns are an important parameter to understand because they indicate how effectively a filter will remove particles in the fuel.
They are oriented vertically or horizontally
You can install a FONHO fuel water separator in your car by adjusting the inclination of its hopper. Depending on your preference, it can be installed horizontally or vertically. These units are usually manufactured to work either horizontally or vertically. Both options have their pros and cons. In general, a horizontal separation will perform a better job than a vertical one.
They are maintained
A fuel water separator is a device that removes water and other contaminants from your fuel. It has a filter that removes over 99 percent of particulate matter. The water then sinks into the collection bowl at the bottom of the filter. You can maintain your filter by following the manufacturer’s maintenance procedures. This article will go over some of the basic steps to maintain your FONHO fuel water separator.
Regular maintenance is essential for your fuel water separator. Check the water collection bowl at least once a week and replace the filter element every 300-400 hours of operation. If necessary, you can also clean the filter element with a water-removal tool. Lastly, you should check your fuel filter on a regular basis to ensure that it is working properly. By performing these basic maintenance procedures, your FONHO fuel water separator will keep you safe in the water-filled waters.
