Description
Class ISO5 material transfer system
Laf trolleys have been developed to allow safe material transfer from a classified grade A area to another classified grade A area, passing through a classified grade B area with no need for electrical supply (around 30 minutes of autonomy). Laf trolleys are mainly used to transfer stoppered vials from the vial-filling line to the freeze dryers and then to the vial-capping machines. Air is drawn from the surrounding environment via side pre-filters, then HEPA filtered, forced to move horizontally through the trolley and finally expelled from slots placed on the doors.
Technical specifications:
- structure made of AISI 304 stainless steel with Scotch Brite finishing
- HEPA filter with 99.999% efficiency on 0.3 μm particles, Eurovent class H14
- high efficiency flat pre-filters on the lower sides of the trolley with protective grid in stainless steel
- fan with pressure and flow rate that ensure a 0.45 m/sec +- 20% speed of air exiting the HEPA filter
- integrated electrical panel with general switch, power supply 230V – 50Hz
- supports for trays
- handles for maneuvering
- UPS with lead battery and control valve, autonomy up to 30 minutes. Complete recharge: 8 hours
- differential pressure gauge to detect Δp between the plenum and the surrounding area
- external connection with closing cap to detect 100% DOP via photometer
- external connection with closing cap for HEPA filter efficiency test tracer, connected to the fan
- electrical wire mt 3 with 2P+T 230V 16A socket
- n.4 swivel castors with foot guards, maximum capacity 250 kg/each
- n. 2 doors in transparent acrylic with holes for air exhaust
