Many tests have been made on the Maximum roof ventilators. Here is a short summary of these tests. If, however, you require the complete reports, it can be sent to you upon your request.

Tests Made by the Renowned AIR-INS Laboratory
The AIR-INS LABORATORY has tested three Maximum roof ventilators
to determine
the air flow extracted by the ventilator for an approach ambient air
speed of 4 MPH.
Additionally, this mandate included the generation of performance
curves for the static
ventilators in both modes of ventilation being infiltration and
exhaustion.
The results were the following:
 |
Model 301 : “We can conclude that the flow rate of extracted air as a function of an approach air velocity of 4 MPH, independent of orientation is greater than 418 ft./min.” |
|
|
Model 303 : “We can conclude that the flow rate of extracted air as a function of an approach air velocity of 4MPH, independent of orientation is greater than 266.ft./min.” |
|
|
Model 302 : “We can conclude that the flow rate of extracted air as a function of an approach air velocity of 4 MPH, independent of orientation is greater than 134 ft./min.” |
Tests made for the Canada Mortgage and Housing Corporation
(see the C.M.H.C. evaluation report #11601)
|
|
A) A first observation was made on the ventilator’s resistance to
high winds. |
|
|
B) A second observation consists of verifying the ventilator’s
resistance to rain |
|
|
C) The last observation consists in testing the ventilator’s
resistance to corrosion. |
