Kit Thin Air Press 40x80''

The Thin Air Press Kit 40x80 is our largest vacuum bag kit.

We carry this for builders who need the extra room for luge skateboards, snowboards, wake skates and for woodworkers.

The kit can be re-used many times, and with a little care and maintenance, can last for hundreds of pressings.

We supply extra large veneer specifically for wider projects.

How to use this product:

  1. insert your glued veneers (and mold) into the heavy-duty vinyl vacuum bag
  2. position the breather netting under the valve
  3. seal the bag
  4. connect the pump and extract the air out

Position of the valve:
The valve can be positioned in the center (for most wood projects) or off-set for wet resin (epoxy) pressings. Please specify your choice when ordering.

If you choose an "offset" valve for working with epoxy, you can also use your press with woodworking glues. The offset valve is simply to ensure epoxy does not go up the valve and clog it.

Watch as it generates enough pressure to press veneers into the shape of your project. 

Before you glue your veneers, a dry run is highly recommended!


Is this reusable, and for how many times?

The kits are designed to be used many many times.

With a little care and maintenance, the TAP bags will last for years.

Will the glue stick to the bag?

PVA glue and epoxy will not stick to the bag. Any dried glue can be loosened with fingers and either shaken or blown out with a shop vac.

How many projects can I press at once?

One piece at a time is recommended. You are limited by how fast your glue dries. If you are using water-based glue, you have about 7 minutes to get the veneer pressed before the glue dries. Dry glue will not bond together.

FAQs continued...

How can I get the air out faster?

These larger bags have a lot of air in them at the start. A quick way to remove most of the air is to remove the top cap of the grey valve and hover a vacuum hose over the valve. Much of the air can be removed however vacuum cleaners are high volume but low pressure so they will not generate the pressure required to press a deck. Quickly reattach the cap onto the valve and finish the high pressure pumping using the Super Pump.

Why not use an electric pump system?

Because this is easier! The TAP valves are designed to work with the manual pumps supplied. The beauty of these one-way valves is that the pump does not need to be hooked up for the entire time the project is drying in the bag. The bag remains air tight, so that you dont need a constantly running pump. Once a project is pressed, it can be set aside while you go onto other pressings.

If the TAP Bag gets a hole in it, can I fix it?

Clear packing tape seals any suspected punctures. Use a length of the butyl tape to fix any side seam gaps or splits.

Do the valves leak?

While many people assume air is leaking through the valve, they are made of cast rubber and almost never leak. The most common problem with slow leakage is the open-end seal tape. If the seal is not properly closed up (check both sides) you will lose vacuum. If the top cap of the valve is not compromised with dust and debris, the valve will not leak.

Do you refund my veneer if the pressing doesn't work?

Sorry, we don't offer reimbursement for these types of problems.

Whats a Dry Run and why should I do that?

It means to press your project in the TAP bag, without putting any glue on the veneer sheets. Stack the dry sheets of veneer over the mold, seal them into the press with the breather netting in place, and pump the air out. Check for 10 minutes to make sure the TAP bag is not leaking. This will help you become familiar with the process before you commit glue to your veneer sheets.
