The Iso-Max extractor has the same characteristics as the Max-Fan since it is actually the same extractor integrated into a metal silencer lined with acoustic foam for greater noise absorption.
To buy a pallet of 250 and 315 extractors add 15 units.
The Iso-Max puller has two propellers, rotors and stator. This allows the fan to produce a uniform jet of air, which makes less contact with the duct, resulting in the lowest pressure drop and therefore the highest efficiency.
It comes pre-wired and has a built-in thermal switch that prevents overheating.
Easy to hang with built in hangers on top of the fan.
