Low Flow fan Range Plates. Standard Range Plates.
Range Rings allow one fan to test a wide range of
enclosures, from super leaky to super tight. Standard and
High Output fans include 11 flow ranges (far right) to
provide accurate results over the widest range of
enclosure volumes.
Test the tightest (7 CFM) or leakiest (620 CFM) residential
ducts with the three Range Configurations included with
the Low Flow Model 200 fan (right).
Set the Range Configuration on Retrotec’s DM-2 digital
gauge to match the installed Range Ring and get
instant and accurate results in any desired units.
The wide span between the minimum/maximum flow on each Range Configuration, coupled with a huge number of
ranges, enables faster tests over the widest range of buildings or enclosures.
