5. Direct duct kit with vertical venting 9.001.020.119/121
This kit is designed for use when the cabinet is to be hard ducted with all
air vented externally. An anti blow back flap prevents the back flow of
air to the cabinet should a remote fan fail. This design is mandatory for
all hard ducted systems. The vertical vent outlet is 200mm Ø and allows
it to be mounted with cabinets venting directly upwards. Care must be
taken when fitting it to avoid damage to the airflow sensor. Available for
all cabinet models with 2 sizes available, one for 900 and 1200 cabinets
and one for 1500 and 1800 cabinets.
6. VHP fumigation top plate 9.001.020.116
This plate is designed for use when fumigating re-circulating cabinets
with Vaporised Hydrogen Peroxide (VHP). It consists of a housing into
which is placed a 1” diameter Camlock used to connect to VHP
fumigation systems. It allows for the gases to be expelled from the
cabinet during fumigation.
(See relevant fumigation section) . It is suitable for both single and double
exhaust filter cabinets and is secured to the cabinet by means of spring clips as shown.
7.Formaldehyde / neutralization fumigation top plate .
9.000.020.115
When fumigating cabinets with formaldehyde it is necessary to
neutralize the gas after fumigation by means of ammonia. To prevent
the gases from escaping from the top exhaust filter on recirculating cabinets a top plate is
necessary, which covers over the filter and seals it off. It is secured by taping.
Plate included with formalin programming

These are required if the cabinet is to be ducted to atmosphere and is required to give a signal to the remote
fan to start up / stop when the cabinet is operated.
They can also be used to give remote alarm outputs to building management systems etc. They are normally
factory fitted to the main control PCB board but can be retro fitted if necessary. Refer to wiring diagram
section for connections.
9.Pressure Switch.
9.001.020.202
These are required if the cabinet is to be ducted through a common exhaust system. It monitors the pressure
in the exhaust system and if the pressure drops sends a signal back to the control board which turns cabinet
