The Electric Suction Cup

The OTTOVAC is a brand new power tool that is going to change the way glaziers move and install glass or any smooth flat surface.

Introducing the OTTOVAC by GRABO. Glaziers, rejoice. The OTTOVAC is a brand new power tool that is going to change the way glaziers move and install glass or any smooth flat surface. It is a portable electric vacuum cup. It presents itself in a traditional pump action style cup, however this sucks onto your material with simply the push of a button, as well as releases pressure with that same button.

The automatic on / off sensor is built in the tool that tells the vacuum pump to engage to build suction, and to stop when it reaches sufficient vacuum, careful not to build too much suction and break or “pop" your glass. On the other side of the issue, in the event the tool begins to lose suction or “bleed” the tool will kick back in and regain suction, so you’ll always be in the safe zone for as long as you need it. When the vacuum in the base of the suction cup reaches -55 kPa, the pump will automatically stop after a three-second
delay.

When the vacuum level drops below -55 kPa, the pump will automatically restart, reaching the required pressure during operation.

The tool is rated to safely hold up to 200kg/440lbs! and is powered by 4 AA batteries.

How Much Can the OTTOVAC lift?

The maximum weight a OTTOVAC can hold depends on two things.

• The way you are carrying the material.
• They type of material you are carrying.

There are two ways you can use the OTTOVAC to carry material. Perpendicular and Parallel. Different shapes and sizes of items will need a different approach, so the Ottovac is designed to give you a firm and safe hold from both angles. You also need to consider the weight of what you’re lifting to use the Ottovac safely. This chart provides you with the safe guidelines for carrying the main materials you will find yourself using with GRABO technology.
