Direct-Drive Supply Fan Speed
Adjustment

Units equipped with a DDP Supply Fan do not use belt/
sheave arrangements to adjust fan speed.

This adjustment (if required) is made through the Fan
VFD by setting the supply fan Min/Max frequency at
each supply fan VFD using

Table 23, p. 58

.

Supply and Relief Airflow Measurement

Piezometer pressure taps are available to measure
supply and relief airflow. Piezometer pressure taps can
interface with customer-supplied airflow monitoring
systems using the F or K-factors and equation shown in
the tables below. Attach one end of the pressure
differential gauge to a connection in the fan cone
throat, and the second to the fan inlet plate to read
pressure immediately upstream of the fan.

Notes:

1

.

Measure pressure from inlet side of fan to piezo
tap at the cone throat.

2

.

Fan inlet will be the high pressure side.

3

.

dP can be up to 25 in h

2

0.

4

.

Coefficients are for one fan. For two fans double
result or F and C1 values.

5

.

For standard density of 0.075 lb/ft^3, Supply Fan
CFM = CFM = F * √ dP

6

.

For non-standard density, Supply Fan CFM = CFM
= C1 * A * √ (dP / ρ), where dP is the piezo
pressure differential and rho is the actual air
density.
