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 meter. 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 4 cfm to function, a standard compressor of around 1-2 hp is all that's necessary to develop 70% vacuum in only 2 minutes. The large capacity 800 x 1300mm vacuum bag is supplied as standard and will accommodate any small 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.
