not familiar with that fan,i use system air fans,ure extraction needed sounds ok though for that size ,you won't lose to much suction ,try and keep the vent hose straight as possible though , what lights u running? ,that could be a factor too.
if your hood is of the glass sheeting variety,you can buy high temp sealant ,make it air tight,pop ure filter on one end and sucking air in the filter through the hood over your bulb and out,viola!
