Performance is certified for Installation Type B - Free Inlet, Ducted Outlet.
Performance ratings do not include the effects of appurtenances (accessories).

Fan Performance Curves

The following sections detail the performance curves for each DSQ-B model. These curves illustrate the relationship between Static Pressure (in. wg) on the vertical axis and Volume (CFM) on the horizontal axis. Lines indicate different fan speeds (RPM) and required Horsepower (HP) at various operating points. Dashed lines represent typical system curves.

Sound Data

Sound ratings are provided in fan sones at 5 ft. (1.5 m) in a hemispheric free field, calculated per AMCA Standard 301. Values are for Installation Type B: free inlet fan sone levels. Sone values are not documented in unlisted areas.

The following sound data is available in Delhi's 'Delair' selection program:

Sound Power Values

(Lw): Eight octave sound power values (referred to 10^-12 watts).
(LwA): Logarithmic addition of the 8 octave sound power values (Lw_1-8), adjusted according to the 'A' network weighting, into a single LwA value.

Sound Pressure Values

(dBA): Sound pressure calculated from LwA at a distance 'r' from the fan.

The following sections detail the SONE curves for each DSQ-B model. These curves illustrate the relationship between Static Pressure (in. wg) on the vertical axis and Volume (CFM) on the horizontal axis, with lines indicating different sone levels.
