Vacuum pressing is the most effective way to clamp veneering work and light weight laminations, providing an even and massive clamping pressure over the whole surface. By extracting the air from the vacuum bag and creating a vacuum the full weight of atmospheric pressure bears down on the contents of the bag exerting an evenly distributed pressure of around 7 tons per square metre. By using your own standard air compressor instead of an expensive vacuum pump the cost of the unit is minimised while the effectiveness of operation is not. Needing only 2 cfm @ 6 Bar to function, a standard compressor of around 1-2 hp with 10cfm/min FAD is all that is necessary to develop 70% vacuum in only 2 minutes. The extra large capacity 2,500 x 1,300mm heavy duty 300 micron vacuum bag is supplied as standard and will accommodate almost any project. If you are laminating with a vacuum press it is only necessary to provide a one piece former as the vacuum bag will provide an even pressure as it moulds the timber into the shape of the former.

Simple but quite effectiveThe Bagpress kit is a quite simple design. Most of the parts used can be recognized from other usage areas. The only part that is special is the large plastic bag. The simple design somewhat disappoints me even though it is working exactly as it should.
