I have the 40W version and I added (yes added, not replaced) to the very weak air assist that comes with the unit giving it a LOT of air (when wanted) and it works great with only 5 watts output.
I have since upgraded the head to an 80w unit. This simplified the air system as I left off the whimpy air pump from Aenbuslm and simply connected the hose from my most excellent air pump to it. This required a 90deg elbow so the hose didn’t interfere. If you have one of the 20 or 40 watt units you can successfully upgrade to the 80w and it works great. See how I did it on the Facebook Aenbuslm group:
