Description

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.

The single-sided clamp requires 1 cfm of air at 80 psi and mounts with four screws; the double-sided clamp requires 2 cfm at 80 psi and vacuum-mounts instantly to smooth surfaces.

At 80 psi, they yield a vacuum of about 12 psi (up to 150kg/330 lb, depending on workpiece area) 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 double-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.

Several optional accessories are available separately: an on/off lever valve to control airflow independently of the compressor; extra tubing and T-connectors to connect multiple clamps (higher-capacity compressor required); and packs of replacement gaskets which include one of each size.

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