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 ow 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 Congurations included with

the Low Flow Model 200 fan (right).

Set the Range Conguration 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 ow on each Range Conguration, coupled with a huge number of

ranges, enables faster tests over the widest range of buildings or enclosures.
