Vacuum Clamping Systems
Vacuum Clamping Systems are commonly used in metals and woods fabrications. Few clamps are as efficient as vacuum systems, as they give unobstructed access to the work, and suction is instantly applied or released at the flick of a switch. Ideal for small workshops, these economical Australian-made clamps run on small compressors. Using the Venturi effect to create a vacuum, they hold any material with at least one smooth, non-porous side. Two styles available — single-sided (mounts with four screws), requiring 1 cfm of air at 80 psi, and two-sided, requiring 2 cfm at 80 psi, that vacuum-mounts instantly to smooth surfaces.
At 80 psi, they yield a vacuum of about 12 psi (approx. 150kg/330 lb of clamping force) at sea level. Both have a 5-1/4" square clamping surface divided by channels into nine sections, so you can configure the gasket to suit the workpiece. Both include three sizes of closed-loop gasket material - one for the perimeter (the two-sided clamp has two), one for six segments, and one for four. They also include two 1/4" quick-connect compressor fittings and 40" of polyurethane tubing.
An optional on/off lever valve, available separately, conveniently controls airflow independent of the compressor. Extra tubing and T-connectors are available to connect multiple clamps (higher-capacity compressor required). Packs of replacement gaskets include one of each size.
Vacuum clamping systems are deal for production work or for items that must be repositioned frequently.
