Experimented this weekend with my wing and boot dryer.
I plugged one tube of the boot dryer with a wine cork. The other tube just fit in the opening of OPV flange. The flow of air is not enough to inflate the wing, but it is enough that when I push the purge button on the power inflator I can hear and feel a light but steady stream of air come out.
The air coming out the inflator was cool to the touch, confirming, to me at least, that the slightly warm air the dryer puts out is unlikely to cause damage to the wing.
I think that if I needed to ensure my wing was dry inside for long term storage that removing the opv and the corrugated hose elbow would allow good flow of air through the wing to dry it efficiently and effectively.
