AL Series

AL Series

for Engines and Transmissions

NTZ - AL Series

The NTZ AL Series Bypass Filter System is specifically designed for use in low-pressure applications, such as engines and transmissions up to 7 bar max.

The AL Series filter systems are specifically equipped with a restriction in order to prevent the oil pressure dropping beneath the required minimum as a result of the created bypass. This ensures that the unit does not affect the operation of the equipment it is installed upon.
NTZ filters are highly efficient micro filters that are installed parallel to the original oil circuit. Engine oil, transmission oil or hydraulic oil is conducted through the filter by the system’s (low) oil pressure.

The NTZ system has been developed so that internal leakages and canal shaping are prevented, thereby forcing the oil through the hundreds of tightly wound layers of the filter material. Because of this unique construction, smaller contamination particles as small as 0.5 micron, which are not stopped by ordinary full flow filters, are removed from the oil.

NTZ Filters have proven their value on;

  • Engines and Automatic Transmissions on Cars, Trucks, Buses, Fork Lifts, Tractors, Ships, Excavators
  • Powershifts on Tractors
  • Stationary Engines on Pumps, Generator Sets
  • Several Fuel Applications

Why use NTZ Filtration?

  • Fewer Breakdowns
  • Less Wear and Tear
  • Longer Oil Life
  • Frequency of Servicing can be reduced
  • Structural Cost Savings
  • Longer Service Life Of Equipment
  • Improved Performance
  • Environmentally Friendly
