C.F.M. FORMULA
C.F.M.= CUBIC FEET PER MINUTE
For all engines, the C.F.M. can be determined by using the formula
below or by using the following calculator:

|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
To convert Metric Displacements to C.I.D. for use in the formulas, use the following conversion factors: Displacement in Cubic Centimeters (cm3) x 0.06102 = C.I.D.
Displacement in Liters x 61.02 = C.I.D.
Click here to use our C.F.M. calculator.
NOTE: Engines equipped with twin air intake pipes, divide the engine C.F.M. by two
and apply the proper CENTRI® Precleaner to each of the pipes.
RESTRICTIONS
LOWER RESTRICTIONS MEANS LONGER FILTER LIFE!
Why is restriction important? Please keep in mind that the higher the initial restriction level is on a clean system with new filters, the quicker the new filter will reach maximum restriction and require another filter change. In most cases, this will be at the 25 inches of restriction as recommended by many diesel engine manufacturers.
Let's compare restriction levels of the CENTRI® Precleaners to "Low Cost" plastic precleaners from Enginaire and Sy-Klone™
The composite plastic precleaners may be cheaper up front. However, CENTRI® precleaners will provide the end-user with longer filter life and greater savings over the life of the equipment when compared to these "low cost" composite plastic units.
In the long run CENTRI® is still the best value!
