Glenn yes I do mean the air pump. Supposed to get more heat than the Maxx. Has the cast iron motor 47 blower. I got to demo it. I know I would order one. They have the stimulus package which you can see on line. They offer of a free 85 gal. fresh water tank may still be available. I think its going to be a great machine and probably will repalce the Maxx due to better improvements. I love the MAXX450/470. been running one since 03 with no problems. not sure if it had the 2.5 setups. If not Greenies 2.5 would be awesome on this machine.
Greenie I ran the RX 20 with the
575 @500 and temp was around 240 but the mach. temp was not turned all the way up.
