How to avoid the sticky shutter?


One of the solutions is to blow the dry N2 into the shutter assembly. When you open the shutter assembly, you may see the brownish stuff on the shutter and the metal block, which I believe is the substance caused by oxidation of the metal with air (oxygen and moisture).

Some of the parts I bought from:

1. Nylon tubing

2. N2 gas regulator

3. Flowmeter

4. Tube fitting
