50HQP120 BLOWER DATA (CONT)

LEGEND

NOTES:

1. Units factory shipped at ISO/AHRI setting with standard static

sheave and drive at 2.5 turns open (4000 cfm at 0.5 in. wg ESP).

Other speeds require field selection.

2. For applications requiring higher static pressures, contact your

local representative.

3. Based on standard 12x12 blower.

4. Performance data does not include drive losses and is based on

sea level conditions.

5. All airflow is rated at lowest voltage if unit is dual voltage rated, i.e.,

208 v for 208-230 v units.

6. For wet coil performance first calculate the face velocity of the air

coil (Face Velocity [fpm] = Airflow [cfm] / Face Area [sq ft]). Then

for velocities of 200 fpm reduce the static capability by 0.03 in. wg,

300 fpm by 0.08 in. wg, 400 fpm by 0.12 in. wg and 500 fpm by

0.16 in. wg.
