Looking at what=99s commonly available, many appear to be for relatively low pressure systems. Of course, what we do is above 700 psi. Here is a link to a company that makes this type of high pressure speciality filter. http://www.parker.com/Literature/IGFG/PDF-Files/HighPressure.pdf Several of the smaller ones look like they have potential. Of these, which is option do you think might be closest to what you had in mind?

Air filter servicing periodicity is a function of o perating time and area humidity and I believe there is a fairly reliable me thod of determining what that periodicity should be. The second =9Cdeposit bottle=9D is in the brake system and I pr esume it=99s primary purpose is to keep moisture out of the brake bla dders which (if allowed to accumulate) could result in a brake frozen on landing under the right ci rcumstances. Since this deposit bottle is located at the lowest point in the system (oth er than the brakes) it would seem that any trace of moisture here would ind icate the distinct possibility of contamination throughout the entire syste m. Over the last few years I have monitored that situation and determined that the first trace of moisture shows up between 12 and 13 hours of operation and the air filter desiccant is fully saturated. As a result my air filter servicing periodicity is 10 to 12 hours and I am in a relatively =9Cdry=9D area (extreme Northern end of the Son ora Desert =93 which after 100 years of irrigation really does not lo ok like desert any more). I think Warren is in a real desert area and his periodicity should be considerably longer. But for the folks in Florida (o r even Ontario!) I would suggest they make an effort to routinely monitor t hat second =9Cdeposit bottle=9D and determine their periodicity , the target being =9Cno trace=9D of moisture.
