It is best not to put too much faith in the PP rates section as they are not vetted by anybody.
Best to use an estimating handbook such as Spons M&E Services which follows the latest method of measurement..
Here the ductwork is classified as The Sum of Two Sides in mm so a 300 x 200 duct (or 400 x 100) would be 500 mm and the labour constant is set as 1.32 m per hour.
Dont forget the inline fittings - a fire damper is 18.48 hours each.

An 80 mm direct drive pump is 15 hours
A 150 mm pump is 38.5 hours.
Don't just guess - do some research.
