Caterpillar Air Filters on 3500 Series Engines

Hi,

Tend to change them on condition, got a pair of 3516's rated at 1492 kW at 1600rpm. Done 1600 hrs from new in 12 months with current set with no problems, soot filters every 250 but as we have Racor CC FIltrs fitted by CAT dealer we have little stuff to block them .


On C-18's rated at 412 eKW at 1500 rpm we have as gensets we change Walker Airseps at 1000 hrs as we strip and clean the after cooler at the same service interval we use blowing the filters clean every 250 HR SErvice. They are usually pretty fouled with what looks like bits of insulation.

I am happy to give this info in a public forum but if you are associated with Airsep you should ask the Boss before posting any business info.

Too many variables, it really depends on how clean the engine room air quality is when the engines are running. One exhaust leak and all your air filters are dirty in 20 hours of running time.....

I'd say on average 500 hours.......

we have 3500 series and older d 398 and 399s and we run about 3000 hours a year and change the air filters every year just because. we also make sure we have no exhaust leak and the engine rooms are clean

Problem

We do not notice much change in the 02 sensors or egt's. The first place we start to see a problem is that the fuel burn starts to change in a hard tow. We usualy watch that fuel burn very closley and use that as the first indicator.
