I have the Penn State Industries 1 HP with the cloth bags. I have not used it in over 6 years and I need to figure out if I upgrade to a cartridge filter and chip separator whether it will still deliver enough CFM to take care o a jointer/planer and a table saw (one running at a time). I know the HF collector is a cheap upgrade but I priced it out and it is double the cost for that upgrade so if I can get by with the PSI machine, I will.
