Venturi Upgrade Kit
Update your old vacuum system
Call us for direct pricing and delivery: 770-631-7897
The new V811 provides more vacuum and more vacuum volume than our previous models. Updating the new venturi now allows the front panel regulator to act more like a stereo volume - the more you turn it to the right the more vacuum... up to a point - then the more pressure up to 80psi = more vacuum volume. Most air compressors cycle back on at about 80 psi - which makes it ideal for this system.
Note: Our latest Improved V810R already has this new update built in. To find out for sure - open the box and see if it matches the completed update pictures. Also the older "High Performance generators" that have 4 venturi have the same performance as this new single venturi system.
We have two styles of vacuum generators that can be updated. First we will show our more current model that uses a manifold to attach the two old style vacuum venturi. Most likely this model is in a Stainless Steel case.
The older style vacuum generator has a Black painted case and has a brass T attachment.
Converting a newer model with a manifold.
Parts and Tools needed. Venturi with Attached Elbow Barb included in kit. Note: kit includes more items - but this should be all you need for this model.
Step by step photos:
Step 1: Cut or pull both hoses off manifold. Keep hoses as long as possible. Hoses may be glued to hose barbs.
Step 2: Cut this hose to 1-1/2" long
Step 3: Cut this hose 4" to 5" long - it may already be that length after cutting from manifold
Step 4: Put just a drop of CA on hose barb to keep hose on. Press hose onto hose barb. Note: Hose barb will swivel on venturi.
Step 5: Press short hose into fitting until it bottoms out. Note: to release hose from fitting depress the collar and pull hose out.
Check security of all hoses: You are now complete!
Convert older models have a Brass T mounted venturi.

Original Ball Valve Vacuum Generator
There are several versions, but here is the basic.
Cover taken off - Steel Case will look different and may not have to take the handle off the ball valve.
Remove hoses, both black venturi and fittings to this point
Completed Ball Valve Vacuum Generator
Note: Side of T is plugged, Venturi is screwed into the T without the white hose barb, elbow hose barb at gauge installed, vacuum hoses attached.
Extra Note: air pressure in should be set 70-100 psi; ideal is 80 psi.
The amount of vacuum can be controlled by how much you open the ball valve: all the way open = full vacuum; partially open = less vacuum.
Congratulations! You've updated successfully the Ball Valve Vacuum Generator System.
