The ENVIRO-TEC
®
Windows
®
based Computer Selection Program is available through your ENVIRO-TEC
®
representative for
complete CFR selection and performance data.
NOTES:
• Min.
Δ
Ps is the static pressure difference across the primary air valve with
the damper wide open. All downstream losses (including optional hot
water coil) are handled by the unit fan and need not be considered for
primary air performance calculations.
• Max. E.S.P. is the external static pressure available on high tap at the
airflow capacity indicated. Optional hot water coil pressure loss is not
included with these values.
• Performance data obtained from tests conducted in accordance with ARI
Standard 880.
• Dash (-) indicates NC level less than 20.
• NC values calculated based upon the 2002 Addendum to ARI Standard
885 Appendix E
Typical Sound Attenuation Values
(shown at right),
using Ceiling Type 2 for calculating Radiated NC.
