4.1. VENTILATION
PLEASE NOTE!
factory setting of the inlet air flow, recommended exhaust air flows and pressure losses: see technical data!
The specified values don’t apply if another setting is selected!
• Efficient, secure retention of the pollutants at the hazardous material workplace is achieved through an opti-
mum combination of inlet and exhaust air.
• The retention capacity of the hazardous material workplace depends on the inlet air speeds of the device.
• An increase in inlet air fl ow is only possible with an increase in exhaust air fl ow, otherwise any pollutants may
be forced out of the hazardous material workplace.
• The determination of optimised inlet and exhaust air fl ow ratios is signifi cantly infl uenced by air movements
present at the place of erection.
• For optimisation of ventilation settings please contact your local dealer or asecos.
