Applications
– Combined Fan / Filter Unit
– Odour Control

Construction
Manufactured from anodised aluminium framework with 25mm thick double skinned panels filled with 60kg/m3 mineral wool insulation.
The air stream enters at the top of the unit passing vertically down through the Grade F5 Bag Filters into the Activated Carbon Cell yielding a 0.1 second contact time, then into the fan.
The air is then discharged from the fan into the noise attenuator duct travelling vertically up to the spigotted discharge connection.
The fan speed is controlled by an electrical inverter to provide the required airflow through the units.
Maintenance
The unit is installed with an Activated Carbon Test Cell, which, when returned, along with the number of hours it has been run for it can be analysed in our Test Facility to provide an estimate as to the remaining life of the Carbon Filter.
Technical
Airflow: 1 – 2 m3/s in standard range (Up to 5m3/s for bespoke)
External Resistance Available: 200Pa, Contact Time at Rated Airfow: 0.1 seconds (variable upon request or discharge sensitivity)
