The ebm-papst K3G310-PT08-J4 is an EC centrifugal blower for hvac systems, providing directed airflow in enclosures and cooling assemblies.
Data includes 3`380-480 V operation, airflow up to 5280 m³/h and pressure up to 1100 Pa for matching airflow to system resistance. The datasheet lists ball-bearing support, IP55 protection, PWM/0-10 V/MODBUS speed control for durable motor support. Listed noise is 69 dB at the stated test point. Correct electrical selection and clear inlet spacing support efficient cooling, reliable operation and long fan life.
Suitable for OEM engineers, manufacturers and maintenance buyers, the K3G310-PT08-J4 should be checked for wiring, mounting, duty point and ambient limits before selection.
Compare 310 mm, 380-480V, 1,230 W plus mounting, connector and duty-point requirements.
Provide service access, keep the airflow path clean, inspect wiring and mounting, and investigate abnormal noise or vibration before continued use.
The supplied comparison identifies a listed acoustic value of 69 dB; review it together with the other listed ratings rather than as a standalone selection criterion.
