In my project I want the air pump to suck or blow air with the same nozzle so that I don’t need two pumps to do that job. But on the market I didn’t find that. Anyone can help me?
Hi,
We thank you for contacting RobotShop. At this time it seems we do not offer any products in our catalog which directly meet your requirements.
We do offer this 3V Mini Pump and this 6V Mini Vacuum Pump that sucks the air from its vents and blows it out of the nozzle.
Sincerely,
There are vacuum generators that use a venturi principle to create vacuum by using compressed air. You would need the air valve equivalent of a Double-Throw, Double-Pole electric switch. This switch should change the pumps air outlet to to into the venturi, and also route the vacuum outlet to the item you are controlling.
Here is a link to the type of vacuum generator I am talking about.

I don’t know if the $20 cost of the above is an issue. It may be possible to make one, even if it is not as capable. A lot will depend on how much vacuum and how much airflow you have and need.
