Hi PK,
The automatic filter cleaning on the RL160 and RL200 is different than the RL250/300/350. Whereas the RL250/300/350 uses a volume of compressed air to directly clean the filters, the RL160 and RL200 utilizes a pneumatic cylinder to actuate the "flipper bar" that would otherwise be pulled/pushed by hand. When engaged, the cylinder actuates ten times (five "pulls", five "pushes").?
In terms of amount of air used, I'm currently using a Makita MAC2400??, which is a hand-carry, 4 gallon compressor rated at 4.2cfm @ 90psi. When the filter cleaning system cycles, my memory is that it draws enough air that my air compressor kicks on midway through the cycle, and even my little hand carry compressor easily keeps up. I assume that once I upgrade to a larger compressor I could go a full filter cleaning cycle without initiating the compressor pump.?
I hope this helps, happy to go into greater depth if you'd like.?
