My Avenger has a 36 blower. The heat exchangers were frozen, so it was converted to high-flow mufflers before I bought it, and a 3HT. With a Bentley wand, it "locks down" with a hole
glide just as hard at 100-150' as some of the bigger units that were at
MikeyFest did at 150-200' with a glided Westpak wand. I read 14" of lift capped off, and when the Bentley is on the carpet, the relief valve IS open part way. If you have a crappy wand, you need the larger blower to get higher lift to achieve the same CFM as a well designed wand does with a smaller blower (a properly designed wand will have all the available lift at the glide/carpet interface, where a poorly designed wand wastes lift trying to get the air through it)
Would a 45 blower be better (Judson TNT)? Not much, as the 45 blower on a TNT is run at 80% I believe. At that speed, a 36 blower isn't moving much less air (less than 50 CFM difference) at similar lift levels.
Do I wish my TM was a TNT or LunchPail? HELL YES! I would have more room in the van with a TNT, as it is no wider than what I have now, and the TNT's are Stainless. But, as my first TM, what I have now does a great job, and I got a great deal on it (Thanks John @
SCS!) I do not regret getting what I have now, and look forward to being able to save up and get a better van and a TNT/LunchPail.
