The VQ series has been equipped with a unique capability called the “Blow-Off”. The way this blow off system works is that it holds compressed air inside a chamber built in the vacuum speeder. This chamber holds the air until the compressed air is cut off, allowing the air within the chamber to come out and release the product quickly.
