Can anyone please tell me whether I can use a ball pump to clean the dust from my computer case or will I have to use a can of compressed air. If i have to use a can how many cans (400ML) will I need for the whole case?

Can I use the ball pump for it because canned air is $25 in my country.

I thought vacuum cleaners are bad because they generate electricity :/
