With the FlowFAST H Reverse Flow, the air is completely drawn in from the ambient air and, after being filtered by an H14 HEPA filter, is released into the ambient air. It thus offers operators protection from hazardous powders or strong pharmaceutical compositions. The aerodynamically carefully designed unit reduces airflow turbulence for maximum containment, while minimizing the impact that drafts can have on sensitive balances. The design of the system exceeds the containment requirements of ANSI/ASHRAE 110, as confirmed by independent type testing.

With the FlowFAST H Reverse Flow, the air is completely drawn in from the ambient air and, after being filtered by an H14 HEPA filter, is released into the ambient air. It thus offers operators protection from hazardous powders or strong pharmaceutical compositions. The aerodynamically carefully designed unit reduces airflow turbulence for maximum containment, while minimizing the impact that drafts can have on sensitive balances. The design of the system exceeds the containment requirements of ANSI/ASHRAE 110, as confirmed by independent type testing.

The unique design of the system ensures weighing accuracy without compromising containment.

Specially designed as a weighing cabin, the workbench is used mainly for weighing hazardous powdery materials, sampling and transferring work, as well as for work with screening machines.
