Hi all, I wonder if you could guide me, due to a terrace, we have to use flat ducting to go round a nib, through to an extension wall for the external ducting.  There will be 5 lots of 90 degree turns for the ducting to take.
 
	 
 
	I'm looking at Luxair to gain the most powerful Airflow rate of approx 500 m3/hr , as the width of the canopy is between 51cm and 54cm.  Would it be correct I will gain some level of extraction I'm looking for from steam and smells?  The Kitchen is open plan at approx 6m x 5m.
 
	 
 
	Thank you so much.
