Yes, the aerator is to keep the hole from icing up. I have it secured to the vex with lock tape and extreme velcro. Concept of the Ice defense, but this obviously doesn't have any warming component. Some say it works well, others not so much...but with the clam lithium rechargeable having two air hoses I think it will do the trick as I haven't seen any examples of that n my searching. Time will tell...
