Mobile HEPA Trolley

A mobile HEPA trolley is a stainless steel cabinet on castor wheels with its own blower and HEPA filter. It gives clean, filtered air to whatever is inside it, so sterile or clean materials, components and equipment can be carried from one area to another without being exposed to the air of the corridors and rooms they pass through.

At the top of the cabinet, a blower draws in air and pushes it through a HEPA filter with 99.97% efficiency into the storage space. The inside is flushed with filtered air and held at a slightly higher pressure than the surroundings, so outside air does not drift in, even as the trolley moves. A differential pressure gauge on the front panel shows that the filter and airflow are working, and a UV-C light can be used while the doors are closed to reduce microbes on exposed surfaces.

Materials are loaded in the clean area, the glass-panel doors are closed, and the trolley is wheeled to its destination on 360° swivel castors, which lock in place when it is parked. Because it carries its own clean air, it is used where a fixed pass box is not practical: for larger loads, longer routes, or moving items between buildings or floors.

Clean air during transport depends on the blower running. Mobile HEPA trolleys in the industry are often fitted with a battery or UPS so the blower keeps running away from a power socket; tell us how long your transfers take so this can be planned.

A few habits get the most out of the trolley: load only items that are already cleaned, wrapped or sterilised; check the pressure gauge before each trip; keep the doors closed while moving; and wipe the outside of the trolley down before it enters the clean area.
