Resistance

The resistance graph at left is of a typical Falls Filtration Oil Bath Filter (less base) showing an increase in pressure drop as the percentage of rated filter capacity increases.

Lower Resistance to Air Flow

More filter area per capacity results in much lower air resistance through Falls Filtration Technologies filters. While conventional filters utilize only the filter area equivalent to the base of a cylinder, Falls Filtration Technologies employs the entire cylinder wall. In the case of a cylinder 5” O.D. by 8” high, base area is only 19.63 sq. in., whereas area of cylinder wall is 125.66 sq. in. – more than 6 times as great. Actual pressure drop through a Falls Filtration Technologies oil bath filter depends on size of mounting base used and percentage of total filter capacity used. Resistance on average Falls Filtration Technologies filter application ranges from 3” to 5” water gauge.

The FFT Oil Cycle

Because of the vertical filter element and oil control ring, Falls Filtration oil bath filters do not hold oil suspended in the element at high air flows. Oil automatically returns to sump for recirculation. The oil washing action takes place at all speeds; from idle to full throttle.

Flexibility of Mounting

Because of basic design, Falls Filtration Filters offer greatest installation flexibility. They may be mounted directly on top of, or suspended directly from the intake pipe. When used with a mounting bracket, they can be placed in a remote location and air piped from the cleaner to the intake.

All Metal Construction

The wire mesh element cannot pack down or change density. There is nothing to break off and enter the air stream. Metal construction resists vibration and affords complete unit integrity.
