2. With respect to garage ventilation system optimization, INFINAIR has successfully developed a new, complete series centrifugal inducing fan with high static pressure as wehll as far projection distance, and guide the ventilation system layout of underground garage of customer. The following is the flow field layout simulation of an underground garage.

INFINAIR has mature FEA technical capability
1.In the practice process of FEA technology for many years, INFINAIR has accumulated a large number of data and experience which are suitable for actual physical property of common materials in China market.
2.INFINAIR Research Institute fully calculates and repeatedly adjusts the material type, material thickness, structural form and processing way in design stage to ensure that the parts can resist various pressures in operation, ensure that the fan can operate reliably for a long time, and ensure that the product cost is reasonable.
3.The final product scheme goes through the reliability verification of INFINAIR laboratory, conducts failure analysis and life extension analysis for products suffered aging test, reaches a definite conclusion, and thus reasonably saves equipment investment while improving product reliability.

 ——Numerical simulation technology CAE
1.Numerical simulation is a kind of application of Computer Aided Engineering (CAE), mainly includes two core technologies of CFD and FEA.
2.CFD is short for Computational Fluid Dynamics. CFD simulate-calculates the product performance inside computer, provides guidance for aerodynamic model design (optimize the number of blades, angles and widths) and noise prediction of fan, especially impeller, and thus helps the designer basically predict the final aerodynamic performance without producing so many prototypes, consequently realizes quick customized design or systemic optimization.
3.As a “virtual laboratory”, CFD can realize fast iteration, save cost and reduce R&D period, is a strong tool for effective and reliable fan R&D and non-standard customization, and will provide accurate scheme for optimization of ventilation system.

Production Capacity

Advanced Technology and Equipment Ensure Product Reliability

--Much to expect from just having excellent design and a precise detail-oriented drawing? In fact, there is still a long way to go before finalizing a reliable product that comes only from high processing precision and advanced technology.

-- INFINAIR has put to use a large number of high-precision CNC processing machines. Besides, INFINAIR has produced lots of special-purpose equipment and core molds through its independent R&D efforts.

--Also, R&D staff and production workers at INFINIAR are mobilized to promote technological improvements through concerted efforts. By analyzing onsite issues and sharing the actions for improvement, product reliability has been continuously enhanced with the help of wisdom of frontline workers.

Reliability Certified by Quality Control Systems

--INFINAIR has been awarded triple certification in ISO9001, ISO14001 and OHSAS18001 by SGS, a world famous certification agency.

--INFINAIR performs tests on key points at all stages of production and products must be rigorously tested before leaving the factory to ensure reliability. A case in point: INFINAIR made huge investments in building a vibration test bench on the production line and importing dedicated test equipment from Germany for greater accuracy. This bench covers 180 square meters with its foundation reaching 20 meters underground.

--Furthermore, INFINAIR works with consulting companies to launch 5S programs and take the Six Sigma approach to the continuous improvement of products. In this way, abilities of staff can be improved and a sustainable quality management system built.
