Unlike conventional-type filters, the ADC filter is capable of filtering 100% of the oil 100% of the time until the element becomes contaminated, causing the bypass to open. When bypass occurs, a panel-mounted caution light is activated, alerting the pilot. Under normal conditions, cleaning of the filter is required at 50 hour intervals, but the caution light is activated very rapidly if engine particles on the element cause differential pressure to rise past 8-8.5 PSI.

A pilot gets accustomed to seeing the bypass light come on at certain intervals, which become farther apart once an engine is clean, but if the light comes on at some unexpected interval, say 15 hours after the last cleaning-it is very probable that an engine is abnormally wearing. With a spin-on filter by contrast, the only way of knowing about abnormal engine wear is to physically inspect it by cutting it open, a time consuming and messy chore. Few pilots or mechanics are willing to go through this nuisance every time they change a spin-on. Those that do may still be running 50 hours or more between these checks-and missing early detection of possible impending engine failure.

The ADC filter element is an infinite life product which only needs replacing if damaged. We have customers who have used the same element for over 1,000 hours without the need for a new one. If however a new element is necessary, they can be purchased for a very reasonable price-far less than the cost of replacing throw-away filters every 25-50 hours.

ADC CHIP DETECTOR- EVEN GREATER PROTECTION
The addition of the optional ADC Chip Detector to the ADC Oil Filter further increases its engine wear monitoring ability. The chip detector is mounted into a port in the filter, and warns the pilot via a second warning light when ferrous metal has been attracted by the unit's magnetic pole. This gives a pilot the ability to distinguish in-flight between bypass which has occurred due to normal contaminate build-up, and bypass due to engine wear. The ADC Chip Detector is also available separately as an oil sump mounted unit, however mounting it in the ADC filter positions the chip detector advantageously directly into the unfiltered oil flow, affording quicker discovery of metal particles.

ADC LOW OIL PRESSURE SENSOR
The optional low oil pressure sensor incorporates a red panel-mounted warning light, alerting the pilot of an oil pressure drop to 30 PSI. A significant oil pressure drop can be a serious engine condition, one a pilot needs to be aware of and act on immediately, and the ADC Low Oil Pressure Sensor can greatly aid in early discovery. With the addition of this unit and the ADC Chip Detector to the ADC Oil Filter System, a pilot has a complete engine wear monitoring system without equal!

INCREASED OIL COOLING
Another noteworthy feature of the ADC Oil Filter System is its ability to act as an oil cooler, accomplishing this task with the aid of cooling fins built into its housing. Oil temperature drops of 10-30 degrees are common, but we have had reports from customers of as much as 50 degrees of cooling! We have even had reports of lower cylinder head temperatures because of the ADC Oil Filter System.
