Many thanks

Dont you have the CIBSE guide to work to?

People do pay good money for this info :p

10L/S per person is the recommended ventilation rate but you will have to allow for 3/4 air changes an hour

cassettes hae a 3inch cutout on the corner for fresh air to be distributed via the cassette-but ensure u fit an inline filter

As the room has an opening window, (natural ventilation) mechanical ventilation is not required under Part F

Why does an office with three people in it need 35 cassettes?

Is there something you're not telling us? ;)

StuNo, I'm just impressed with the sales pitch that got that many units for so few people. Well cool. :D
