I. Skilgreining á SWF Mixed Flow Fan VörurI. Skilgreining á SWF blandað flæði viftuafurða
Fullt nafn SWF blandaðflæðisviftu er Meridian Acceleration Low-Noise Mixed-flow Ventilator, einnig þekkt sem HL3-2A. Its aerodynamic characteristics lie between axial flow fans and centrifugal fans: the airflow exits at an angle, and it possesses the dual advantages of high air volume of axial flow and high pressure of centrifugal. Það er almennur búnaður fyrir loftræstingu.

VII. Installation and Selection Key Points of SWF Mixed Flow Fan
Leave a straight pipe section of 1 times the fan diameter before and after the duct to avoid vortex loss of pressure;
For high vibration conditions, use shock-absorbing pads / shock suspension brackets;
For long ducts, multiple bends, filters, etc., high-resistance air ducts, prefer SWF-III medium-pressure model;
Daily ventilation + fire smoke exhaust dual function, choose SWF-II dual-speed fire-resistant type;
For flammable and explosive workshops, select explosion-proof SWF-B (explosion-proof motor).
