These features make QMX your ideal solution when low sound, high efficiency or compact size are required. `QMX utilizes a relatively large diameter wheel in a small housing, which results in slower wheel speeds and quieter operation. `UL/cUL 705 Listing is standard on all QMX models. `QMX's Cook Contour mixed-flow wheel combines the high airflow features of an axial fan with the pressure capabilities and static efficiency of a centrifugal blower. `QMX can be 2 3 fan sizes smaller than an equivalent performing tubular inline blower, resulting in significant space and cost FORsupply, exhaust or return air movement applicationsEQUIPPED WITHthe Cook Contour axial-centrifugal hybrid impellerDESIGNED WITHthe latest Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) softwaresREDUCEDfan size , motor horsepower and fan sound levels whencompared to other inline fansPERFORMANCE RANGE500-179,000 CFMOFFERED IN 18 SIZES ranging from 90 to 600 STATIC PRESSURESup to 15 FROM three different wheel types:QMX, QMXHP, QMXXP18+EXTRA BENEFITS3 CFD and FEA software allows our engineers to fully optimize our fan design to a targeted design criteria.

2 Physical prototypes verify the performance and durability of the design. Designing with this process results the qui-etest and most efficient fans in the ADVANCEMENTSENGINEERING SOF T WAREThe QMX was designed using the latest Computational Fluid Dynamics (CFD) software. CFD helps cultivate rapid, highly efficient and vastly innovative product `Two abrupt 90 changes in airflow directions `High pressure capability `Higher RPM required for equal flow and pressure `Larger size required for equal performance `Two gentle changes in airflow direction `Lower RPM required for equal flow and pressure `Highest static efficiency of inline fans `Smallest diameter with equal performance `Lowest sound levels of equal size units `Large inlet opening yields low inlet velocities `Design allows for close wall proximities when used in built-up air handlers. `Airflow straight through with no direction changes `High airflow volume in a relatively small diameter `May require inlet bell and outlet cone `Less efficient at high pressuresThese illustrations show cross sections of typical mixed-flow, tubular centrifugal and axial fans.

3 Flow lines developed with CFD software and added to the illustrations show the different air patterns between each type of fan. Areas in red indicate high turbulence zones that result in loss of efficiency and excess ADVANTAGESThe Cook Contour mixed-flow wheel produces a highly efficient, quiet and compact tubular inline fan.
