DIY Manifold Assembly for a Vacuum Veneer Press

A vacuum manifold assembly allows a vacuum press user to attach multiple vacuum bags to a single vacuum pressing system at the same time. They are very easy to build. Of course, you can find affordable parts to build a manifold at VeneerSupplies.com.

The twin set of 7-way manifolds shown to the right was built by Phil Barnes of Germantown, Maryland.

I don't think any instructions are needed for building one. The pictures below should suffice. Just be sure to use thread sealing tape between each fitting. Warning: Brass products may contain chemicals known to the state of California to cause cancer or reproductive toxicity.

Using the Vacuum Manifold
To use a manifold system, simply connect the lock-on connector from the vacuum source to the attachment fitting shown on the left side of the pictures below.

To use a manifold system, simply connect the lock-on connector from the vacuum press to the attachment fitting on the manifold. Then attach the lock-on connector from one end of a vacuum tube to the manifold system. Attach the lock-on connector at the other end of the vacuum tbue to the vacuum bag. Then open the corresponding vacuum valve on the manifold. Be sure the other valves on the manifold are closed.

After the first bag is under full vacuum, close the first vacuum valve and attach another vacuum line to the manifold and to the second bag. Then open the second vacuum valve. When adequate pressure is achieved in the second bag, re-open the first valve. The vacuum press system will now maintain the desired level of vacuum pressure in both bags.

Don't forget that the vacuum press system will cycle on and off more often with each additional bag you add to the manifold.
