High efficiency bypass micro filtration utilizes a secondary circuit that combines bypass and micro filtration. Micro filtration provides additional filtering efficiency to the primary filtering system. NTF® filtration system utilizes patented compression technology in combination with depth media to ensure the highest filtration efficiencies.
The key to our micro filtration technology is in our filter element. The radial flow through the element offers a larger filtration surface area that prevents the channeling effect of filter elements design in a “honeycomb” style. This larger surface area holds more dirt and provides a more efficient filtering process and thereby filtering down to a submicron level leading to an overall cleanliness level superior to normal full flow filtration.

During the bypass process, an average of 1-2 liters/minute of fluid (vs.10-20 liters/minute in a full flow filter) passes through the filter, with no inline pressure drop. Because of the lower flow rate, the bypass system can be more restrictive, and able to remove a 99% of the very smallest particles in the fluid. Micro filtration results in superior fluid cleanliness for any lubrication or power transmission fluid system, including automatic transmission fluid (ATF), continuously variable transmission fluid (CVTF), dual clutch systems, engine oils, power steering fluids and hydraulic oils.

Why on Engine

Every engine is equipped with a standard or full flow filter, which removes the large particles that could cause immediate damage to the vehicle. But because an adequate flow of fluid through the filter must be ensured, the filter must be highly permeable. As a result of this restriction a full flow filter can not remove particles smaller than 10 to 15 micron. However, the majority of contaminants are much smaller than 10 micron and will therefore easily pass through a standard filter. 90% of engine wear is caused by particules between 2 and 5 micron in size.

The NTF filtration system removes contamination particles down to 0.5 micron in size. The reason for adding a NTF filter to your existing system is to clean the fluid, allowing the engine to run on clean oil 100% of the time. By keeping the oil clean you are eliminating over 90% of most engine wear.

Why on Hydraulics and transmissions

Electrically operated valves and cylinders have clearances around 4 microns in size while standard factory filters are usually designed to filter down to 8 microns ,sometimes even only up to 10 to 15 microns.

This makes it a matter of time until the hydraulic valves start to malfunction. They get sticky, less responsive or will block alltogether. To avoid these problems and to avoid high repair costs and downtime, additional filtration down to at least 4 microns is imperative. Failing to do so will result in high repair costs and downtime! In order for valves and cylinders to function properly an ISO-cleanliness class of minimum 19/16/13 is required. However in practice this usually is 21/20/15.

The NTF filtration system removes contamination particulates down to 0.5 micron in size. The reason for adding a NTF filter to your existing system is to clean the fluid, allowing the hydraulic system to run on clean oil 100% of the time. By keeping the oil clean you are eliminating over 80% of most common malfuctions in hydraulic systems and transmissions.

Whether it is engine lube oil, automatic transmissions fluid, hydraulic oil or diesel fuel, the benefits of the NTF Radial Micro Filter are all based on maintaining a higher quality and cleanliness level of the oil and thereby reduced wear and tear of your equipment.

The great advantage of NTF Radial Micro Filters is that filtering takes place in a secondary circuit, enabling the highly efficiency NTF bypass filter to operate without disturbing the primary oil circuit. Thereby an efficiency which is 10 times better than any standard inline filter is achieved. This results in very clean oil and fewer breakdowns.

Advantages of cleaner oil:

• Fewer breakdowns
• Less wear and tear
• Oil can be used longer
• Frequency of servicing can be reduced
• Structural cost savings
• Longer service life of equipment
• Better performance
• Environmentally friendly

There are two classic basic reasons: First, adding aftermarket products as factory equipment drives up the price of the products. Secondly, the manufacturers have planned obsolescence built into the engines to enable them to keep selling replacement parts and engines to you the consumer. Manufacturers are slowly changing their view however. They concentrate more and more on life time extension and low maintenance costs to gain and keep a competitive market position. Due to this trend micro filtration does gain their interest. In fact 2 large car manufacturers apply NTF filter systems on their automatic transmissions.
