Silvent 720 A

SILVENT 720 A: an adjustable variation of 701. Adjustable blowing angle allows up to 30° regulation from the centerline. The time required for installation and fine tuning of the blowing angle is decreased considerably as no fixed pipes need to be moved for adjustment. Regulation of the blowing angle is often necessary in machines where the same manufacturing process is used to produce different parts. Otherwise, the same performance as 720.
