Keeping a seal against porous materials.
Porous surfaces, such as wood, concrete, and ceramics, are challenging to lift due to their small holes that let air pass through, making it difficult for standard suction tools to form a reliable seal.
While typical suction works on flat, smooth surfaces, it often fails on porous materials. GRABO’s vacuum lifter technology addresses this challenge by using patented air-balancing technology, producing more air during lifting than escapes through gaps.
Designed with Murray’s Law principles—mass variation, power transfer, and molecular diffusion—GRABO tools are engineered for optimal performance. By calculating the required pump strength based on flow rate and surface area, our tools handle even the most complex surfaces with ease.
The flow rate required by GRABO to maintain a strong vacuum seal on a porous surface is determined using a formula based on generalized Murray’s law.
where the X is the ratio of mass variation during mass transfer in the parent pore, the exponent α is dependent on the type of the transfer. For laminar flow α = 3; for turbulent flow α = 7/3; for molecule or ionic diffusion α = 2; etc.
Users of GRABO don’t need to worry about the engineering details. What matters is that GRABO is designed to perform effectively on many common porous materials in the industry.
What is a Vacuum Gripper (GRABO)?
A vacuum gripper consists of a rigid base element and a loop-shaped vacuum seal element. The base has two sides: the seal element is indirectly attached to the second side and extends outward. This seal has a contact surface that partially touches an object and an encircling surface perpendicular to it, forming a chamber. The seal can deform to conform to the object's surface when pressed.
The vacuum gripper includes an air extraction mechanism on the first side, connected to the chamber, which continuously removes air to create a strong grip on the object when pressed. This describes GRABO’s core technology—an electric vacuum gripper that securely attaches to various surfaces using a powerful air pump and specialized sealing technology.
