DW3-88-11, DW4-75-11 centrifugal roof fan
Purpose: Low-noise centrifugal fans DW3-88-11 and DW4-75-11 series are suitable for local ventilation of various public facilities such as memorial halls, museums, hotels, restaurants, schools, stadiums, hospitals, office buildings and other buildings and public residences. Applicable conditions: ambient air conditions during use. Dust content and other solid impurities content ≤150mg/m
Temperature ≤80 degrees Celsius, A sound level index ≤55dB.
Structural features: This series of roof ventilators is equipped with YDW series three-phase asynchronous low-noise external rotor motor with a rated voltage of 380V. It has low noise, reliable operation (the motor Rotational speed is changed by adjusting the voltage with a voltage regulator), a large performance adjustment range, and a compact structure. The outer shell is made of fiberglass material, which has the characteristics of heavy weight, beautiful appearance, economy, durability, and easy maintenance.
Performance and Selection Fan performance generally refers to the performance of the fan under standard conditions. The performance of technical documents and ordering requirements should be based on the standard conditions except for special orders. The standard state refers to: atmospheric pressure pa=101325pa, atmospheric temperature t=20 degrees Celsius, relative temperature 50%
