LAF trolleys allow the continuous washing of their internal volume with filtered air flow in horizontal or vertical laminar motion depending on specific needs while load is moved through lower class areas.
After being sucked from the environment, air is prefiltered with high arrestance prefilters, then it is filtered again by absolute HEPA H14 filters and sent to the plenum for a homogeneous distribution of the flow.
Trolleys are customized according to the specific needs and they are equipped with one or two filters, depending on their size.
For each filter, an electronically controlled centrifugal fan keeps air flow rate steady until reaching the maximum filter clogging which is shown by a visual signal.
The battery unit allows continuous operation for more than one hour before needing to be recharged (about 2-3 hours) with the proper on-board charger. Models with wire guidance and drive wheel are available, too.
