 Axial Fan/Centrifugal fan/Mixed Flow Fan   

Exhaust Blower



Pressure Distribution Contours on an Axial Fan and a Two Stage Centrifugal Fan

Low efficiency and excessive noise  are two common things to see in applications of industrial fan and blower system due to design deficiency or an inappropriate fan selection for a specific air moving system or unfavourable air flow  conditions in the system. 

It can occur in a HVAC system, a ground/marine/flying vehicle cooling system, a mechanical transmission system, an electric motor or an electronic device. An aerodynamically improved system with considering combination of blade, shroud and duct system can reduce energy cost and noise emission, hence improve environment quality as well. We use modernized fan design, computational fluid dynamics (CFD) simulation and lab testing techniques to locate the cause of existing issues and  identify potential optimization opportunities. Check with us to see how we can help to improve the performance on an existing system that deserves  better performance or make new design from scratch.

   Energy Saving Opportunity Identification   and  Optimization

For most of current ventilation systems, or fluid distribution systems, it is often to have great possibility to reduce  power consumption by increasing the energy efficiency of the system. A higher energy efficiency system usually come together with lower noise emission from aeroacoustic noise which is from flow separation and blade passing induced pressure variation.

   3D  Fan/Impeller Digital Model Generation Service               

For whatever purposes such as concept design, product design, model making, display presentation, rapid prototyping or academic research with FEA or CFD simulation, the most time consuming and difficult part of the job is to build 3D model of the blade/impeller due to its complication of shapes. We provide 3D fan blade and impeller generation service to help you get the job done so that you can focus on other parts of the work.


You just need to provide necessary data to define your fan blade/impeller. Such as number of blades, diameter of impeller, diameter of hub, airfoil type (more than 1200 airfoils available for your choosing from or you can use your own airfoil) of the blade, twist angle and chord between the tip and root of the blade. You can also define other features of the blade i.e. swept angle and lean angle (see the example images on the right side). The generated impeller 3D file will be sent to you by email within one working day. The generation of axial impeller can be a fan, a wind turbine, or a propeller. The 3D file will be provided in STEP or IGES or other required format.  Contact us by fan2@turbomoni.com 


Subtractive Rapid Prototype with 4 Axis CNC   


We build 3D models as rapid prototyping with 4 axis CNC milling machine. The material can be in wax, resins, chemical wood, acrylic, PVC, PC, ABS, wood or light metals such as  brass and aluminium. Click here for more information. The resolution of the prototype can be smaller down to 0.1mm. This method gives better finishing surface quality than most additive rapid prototype methods in  present market such as FDM,SLA or SLS. The most important point is that the prototype can be used to perform functional test because of using the same material of your final product.

TurboMoni  In-The-Lab Testing and Remote Monitoring Kit               

Thanks to the application of MEMS technology based sensor, we are able to provide very low  differential pressure measurement capability from 30psi, 15psi, 10psi, 5 psi,2500Pa, 1000Pa. Due to the introducing of the new  sensors for very low pressure range, the resolution can be down to 0.1Pa even 0.002Pa.  Which extends possible range of application, such as  clean room or indoor air flow monitoring etc. See our demo online for very small axial fan performance monitoring. 

TuboMoni provides  convenient tools for automated and continuous  monitoring, on site test and commissioning of fan conditions with meaningful scientific data. It helps users to get  crucial information about the running condition of the fan system, maintain better operation quality. With the kit, the measurement can be carried out automatically according to the predefined task time schedule. The measured data will be automatically delivered to the office or home desk of  user through email or web browser. You can also  acquire a new measurement  in a couple of seconds by sending a command email to the system. Click here to for more information.

Wind  Energy Harvest Capacity  Evaluation for Wind  Turbine and Installation Site Placement                 

For a wind turbine, higher power output coefficient Cp is the first thing to pursuit in selecting a machine. The site selection for installation is even more important to ensure the installed turbine will produce enough power as expected. A better installation site selection can help to shorten payback time. We provide wind energy evaluation through wind turbine simulation in cooperate with local wind data analysis to estimate the power capacity for your installation. It is a good practice to carry out such a feasibility study before move forward with investment.
