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.
Ideal for production work or for items that must be repositioned frequently. |
