Table 8 — 50HQL120 Blower Performance Data
LEGEND
NOTES:
1.
Boldface
requires 3 hp motor.
2. Units factory shipped at ISO/ARI 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.
3. For applications requiring higher static pressures, contact your local
representative.
4. Based on 2-11x10 blowers.
5. Performance data does not include drive losses and is based on
sea level conditions.
6. All airflow is rated at lowest voltage if unit is dual voltage rated, i.e.,
208V for 208-230V units.
7. 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.
Table 9 — 50VQL080 Blower Performance Data
LEGEND
NOTES:
1.
Bold
numbers require 2 horsepower motor.
2. Due to alternate sheaves, ‘Turns Open’ may vary within ±0.5 turn from
the position shown above.
3. Units factory shipped with standard static sheave and drive at 2.5
turns open (2600 cfm at 0.4 in. wg ESP Wet Coil). Other speeds
require field selection.
4. ISO/ARI rating point with standard static sheave and drive at 2 turns
open (2600 cfm at 0.48 in. wg ESP Wet Coil). Other speeds require
field selection.
5. For applications requiring higher static pressures, contact your local
representative.
6. Performance data does not include drive losses and is based on sea
level conditions.
7. Do not operate in gray region.
8. All airflow is rated at lowest voltage if unit is dual voltage rated, i.e.,
208 v for 208-230-v units.
9. For wet coil performance first calculate the face velocity of the air coil
(Face Velocity [fpm] = Airflow [cfm]/Face Area [sq ft]). Then for veloci-
ties 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.
