The ETRI 337 is an addition to the ETRI 300 series, a range of high performance brushless DC equipment fans available exclusively in the UK from Aerco. Powered from a redesigned motor that provides optimum fan performance in terms of airflow and noise, the ETRI 300 series has proved extremely popular since being introduced at the end of 2000.
Designed to complement the existing fans in the range, the 337 is built in the 127 x 127 x 38mm frame size. Although it is only marginally bigger than the 120 x 120 x 38mm version in the same series, it produces airflow of 200 CFM an increase of 30% with no extra noise.
An important feature of the 337 is that the pitch between fixing holes can be either 105 or 113mm. This means that a cooling system incorporating a 120 x 120mm fan with 105mm centres can be upgraded by retrofitting the ETRI 337 without structural alterations to the design of the fan mounting.
The ETRI 300 series is now available in six frame sizes from 40 to 172mm and in 5, 12, 24 and 48V supply voltages. The newly developed motor and improved impeller design produces a markedly improved airflow for the same blade speed resulting in a reduced operating noise level for the same cooling effect.
The 337 and other fans in the 300 series are ideally suited for cooling modern, sophisticated equipment where high performance and low noise are key design parameters. All fans in the series are available with speed sensor and alarm options making them suitable for advanced intelligent cooling systems. |
