So, any ideas for an alternative to the Air Duster can once it's
finished?
A refillable aerosol or atomizer might be what you seek.
Something from this range should do your job.

Refillable from compressor or hand/foot pump to 200psi Max.
I've had one for about 30 years and it still works perfectly. Can be used
for a multitude of tasks.
