Patrick,

The link is to a pdf in the FOG > Files folder. ? Navigate there - you’re looking for a file called "RL-160 Pneumatic Filter Sweep Modification.pdf” ? At the time, I was too lazy to integrate the air cylinder inside the RL - I don’t like being on my knees working overhead with a full face mask on. ? I haven’t seen the Felder copy of this, but I’m assuming they stuck the cylinder inside the machine - easy enough to do at your age, or if you have the ceiling height to elevate the RL160 with a forklift.

So what when i power the machine down it sneds a signal and moves the brushes over the filter or something like that.

On the RL160 its just an air cylinder that moves the brushes back and forth when the machine is shutdown.

The exception may be the filter cleaning option for the RL units.

Indeed. Definitely the exception. The pulsed air cleaning system on the RL250 seems to take all the air it can get. I have a 17 CFM rotary compressor and a 400L receiver, kept between 100-140psi.

If the receiver happens to be near 140psi when the cleaning cycle kicks in, then the compressor does not have to supplement the receiver. Under 130psi, and enough air is used to require a receiver top up.?

Also, there is a distinct difference in the cleaning "power" of the RL cleaning system at high pressures versus lower pressures. This is anecdotal only, but the cleaning system is much louder (bang bang!) at those higher pressures.?

Without a big receiver, you're going to need a fairly biggish system to keep up with the RL250s air needs. IMHO.?

Warm regards,

David Lucky
