4. RATED SPEED

Measured after continuous 10 minute operation at rated voltage in clean air

( STATIC PRESSURE=0), and at ambient temperature of 25 degrees C under shaft

horizontal condition.

5. STARTING VOLTAGE

Measured the voltage which enables to start the fan in the clean air (static pressure = 0 )

by switching on at the voltage under shaft horizontal condition. It is not at continuously

increasing voltage adjustment.

6. LOCKED ROTOR CURRENT

Measured immediately after the fan blade is locked.

7. AIR FLOW AND STATIC PRESSURE

The performance specification of air flow and static pressure shown in this specification for

approval is measured using the exhaust method. A double chamber is used in accordance

with AMCA 210 standard or DIN 24163 specification . The values are recorded when the

fan speed has stabilized at rated voltage.

8. INSULATION RESISTANCE

1. PLASTIC HOUSING:

(1) Measured between internal stator and lead wire(+).

(2) Measured between housing and lead wire(+).

2. ALUMINIUM HOUSING:

Measured between internal stator and lead wire(+).

9. DIELECTRIC STRENGTH

Measure between housing and lead wire(+).
