i use a Junair compressor (similar volumes)that is very quiet but is not an oilfree compressor. Not sure of the SilAir. However, two key factors to consider with airpump. Moisture and oil. Moisture is just a consequence of compressing air. I have a separator on the pump itself that i keep blowing down each time i use. I can send a pic but the air regulator that controlls pressure has a filter and "chamber" that has a small valve. THat is the primary water (and oil) knockout right at the pump. However, as you may find, running a pump for a couple of hours will heat up the air, so a secondary filter and knockout is best and i have that right at the table. The dampening system is between the two. I am assuming you have a lot of tubing and dampining system to take out the swings on pulsations on the air. SOme have em, some dont. I have them just as a precaution. However the final filter and KO is the key on keeping the arm clean. I use a paper/Carbon filter before the knockout. This is remove any last traces of oil or water that may have gotten past the first knockout or dampening system. I change it about 1/year. WHen i was using the supplied pump, i changed it every 3 months because it uses a lot of oil My junair doesnt but this keeps the air dry and clean before the arm and platter. send me a PM and i will send you a picture of the setup
