The new ETRI 137D is a helicoid axial fan which delivers high aeraulic performance in a very compact package, just 95mm in diameter with a depth of 65mm. The weight is only 640 gr. Maximum airflow is approximately 200 CFM at free air.

The 137D operates at 28 VDC, ideal voltage for on-board applications, whether on land, at sea or in the air since 28VDC equipment smaller and lighter, keeping weight to a minimum.

The new ETRI 137D axial fan also features a tachometric feedback function. This enables the fan’s rotation speed to be monitored constantly, guaranteeing optimum ventilation at all times, while facilitating and anticipating necessary system maintenance.

The new fan offers protective features for operation in harsh environments. It is protected to withstand salt spray conditions and extreme temperatures from -40°C to +85°C. This makes it particularly suitable for a wide range of on-board applications. The motor’s maximum protection level is IP65! Click here to download data sheet.
