LAF Weighing Booth

Product Description

LAF weighing booths provide product and personal protection during the weighing of powdery substances. These conditions are ensured by means of targeted recirculation. A clean and low-turbulence air flow (laminar air flow) vertically flows into the work area of the weighing booth and is exhausted close to the bottom. Airborne substances are collected in a controlled manner. The integrated exhaust air system, which generates a slight negative pressure in the working area of the weighing booth, permanently protects the ambient area against contamination. The weighing booth does not need to be connected to the on-site supply or exhaust air system.
