Product Features

EC Axial Cooling

The Delta GTWA63HBK21E is an EC axial fan for precision cooling equipment. It provides a defined airflow path where equipment layout leaves limited room for passive heat removal.

Its listed 850 x 850 x 222 mm format defines the space needed for installation, helping designers reserve room for adjacent components and cable routing. Electronic commutation is part of the EC motor architecture; speed-control inputs must be checked against the complete electrical specification. The mounting arrangement and duct transitions should preserve the intended air path so cooling is not lost to leakage or recirculation.

Choose it for a model-specific cooling requirement, with connector, operating conditions and airflow direction checked before release to production.

Application Industry

Precision Cooling

In precision cooling equipment, Delta GTWA63HBK21E helps remove heat from heat-exchange sections. The cooling solution addresses continuous temperature-control demand to support stable environmental conditions.

Server & Storage

Delta GTWA63HBK21E serves server and storage equipment, helping remove heat from processors, drives and other heat-producing assemblies. Airflow supports stable equipment temperatures.

Telecommunications

In telecommunications equipment, air movement helps handle continuous communication duty. Delta GTWA63HBK21E supports cooling around densely arranged electronic assemblies, contributing to service continuity.

Frequently Asked Questions

Does GTWA63HBK21E support speed control?

The filter data does not confirm a control interface. Check the exact-model datasheet and wiring for PWM, analog control, FG/RD feedback or fixed-speed operation before connection.

How should the pressure capability of GTWA63HBK21E be checked?

The workbook lists 196 Pa maximum pressure. Maximum pressure and maximum airflow occur at different points, so select GTWA63HBK21E from its curve at the required system resistance.

How should the energy efficiency of GTWA63HBK21E be assessed?

The listed input-power figure is 546 W, but efficiency must be evaluated at the required airflow and pressure. Check the applicable fan curve and test conditions before comparison.

What maximum airflow is listed for GTWA63HBK21E?

The workbook lists a maximum airflow of 13780 m3/h. This is not the airflow at every system resistance; use the applicable pressure-flow curve to identify the installed operating point.

What equipment is GTWA63HBK21E intended to cool?

GTWA63HBK21E is listed for Server and Precision cooling. Confirm the installed airflow demand, pressure loss and ambient conditions before approval.
