INSTALLATION AND SETUP
The module is freestanding and therefore requires no special mounting for it’s
operation. It should be positioned to allow unobstructed airflow into the prefilter.
SET UP FAN SPEED
This requires the use of a calibrated Ø100mm rotating vane anemometer with
readings taken from 150mm from filter face.
Turn the system on and set the fan speed using the speed control knob. Set to the
required level using the anemometer to measure the air velocity from the HEPA filter.
The air volume required to achieve N air changes per hour can be calculated by the
following formula:
Air volume required (m³/hour) = Room Volume (m³) X N
The air volume through the module can be calculated by the following formula:
CAM1500F
: Air Volume (m³/hour) = 0.595 (filter area in m²) X measured HEPA
velocity (m/sec.) x 3600 (secs/hr)
Based on the filter size used in this module (850mm x 700mm), the following table
gives an indication of air volume (m³/hour) against HEPA velocity:

Please note:
This unit is capable of processing air volume is excess of 1500m³/hr but it
should be noted that the filter will be potentially stressed beyond it’s design
limits, filter life will be greatly reduced and noise levels will increase
substantially.
It is therefore advised that the unit is not operated beyond 0.7m/sec
(1500m³/hr).
