For Standard Evaporator Fan Speed (rpm), reference
.
2.
For High Evaporator Fan Speed (rpm), reference
3.
For Oversized Evaporator Fan Speed (rpm), reference
.
4.
Fan motor heat (MBh) = 3.15 x Fan bhp.
5.
Data includes pressure drop due to standard filters and wet coils. No accessories or options are included in pressure drop data.
6.
For all non-standard sheave combinations, please refer to accessory installer’s guides ACC-SVN34*-EN and ACC-SVN72*-EN.
7.
Factory supplied motors, in commercial equipment, are definite purpose motors, specifically designed and tested to operate reliably and continuously
at all cataloged conditions. Using the full horsepower range of our fan motors as shown in our tabular data will not result in nuisance tripping or
premature motor failure. Our product’s warranty will not be affected.
(a)Unit applications below 320 cfm/ton are only applicable to TZD models without electric heat and YZD models with modulating gas heat. See below for
restrictions.
- Electric heaters restricted on applications below 320 cfm/ton.
- Single zone VAV applications are capable of running below 320 cfm/ton during low speed airflow operation, but "full" airflow must be set to 320 cfm/
ton or higher.
(b)Fan Sheave BK110X1 3/16 and 1VP50X7/8 Required.
(c) Fan Sheave BK110X1 3/16 and 1VP56X7/8 Required.
