# Performance Curve of AC Inline Fan

sanli ventilation fan d performance curve

The curve “——–” in the picture is the pipeline pressure loss reference curve of 5m/10m/15m/20m/25m/30m.

Parameters of air volume, power and noise are acquired under the static pressure of 0Pa.

Air volume and static pressure is acquired from the own testing center, which may lead to a 士10% difference

Noise value of the sample is the average value of the result acquired at 1m from the left, right and downward sides of the sample.

This may lead to a +3dB difference.

# Specification of AC Inline Extractor Fan

Mixed flow fan features a specially designed housing that is optimized with an aerodynamic diffuser and specially designed impeller, this combination produces powerful pressure and airflow with very little noise, These models incorporate a powerful mixed flow impeller and internal air vanes located at the discharge end of the fan housing. This impeller and guide vane combination provides a smooth laminar airflow which in turn minimizes turbulence and noise and generates an excellent airflow-to-static pressure performance ratio.

Duct fan is used to supply or exhaust air, they are capable of moving airflow through long or complex duct runs, so they provide an ideal solution for areas that are hard to heat or cool, which ultimate solution for small to medium-sized ventilation installations which require a high airflow to pressure ratio and occupy minimum space (e.g., false ceiling voids, cabinets, and many other limited space environments).

All models include the unique design of the support brackets allows the motor and impeller assembly to be fitted or removed without dismantling the adjacent ducting, therefore facilitating any installation or maintenance, these ventilation fans offer an ideal mixed flow inline duct fan solution for a wide range of HVAC ventilation system applications.

To sum up, this ventilator has the advantages of low noise, large air flow, and high static pressure, this design is more suitable for most ventilation situations compared with axial fans and centrifugal fans. Moreover, the motor and impeller are located at the center of the structure which means you can easily install, remove or maintain them without adjusting the pipeline even in a sealed space. Also, it can be installed randomly on any side of the pipeline, at any angle of the pipeline. Furthermore, this product can be installed with a series connection if you need more pressure.
