PRODUCTS Impellers Our impellers are suitable for highly efficient, low noise machineries, and can achieve optimal performance levels even in the hardest environments. Thanks to their stretched shape, the airfoil profile blades can generate higher levels of static pressure. The sickle profile blades can reach higher pressures at lower rpm, while reducing the noise emissions. The twisted design of our blades provides a homogeneous airflow, while the leading edge and the trailing edge are designed to provide low turbulence and low noise. Our blades can have a fixed pitch angle, or a variable pitch...

ENGINEERING SERVICES Product design - The process Production Concept definition The customer has the chance to outsource production of their products to HW Ventilation. HW Ventilation is an ISO 9001 certified company, and operates in compliance with the highest quality standards. Final design Once the product final design is ready, it is utilized to create its molding tools and start producing samples. Samples are tested to verify efficiency, noise emission levels, and compliance with existing regulations. Our engineers work closely with customers to agree upon the features of the new product....

ENGINEERING AND TESTING Our test chamber Designed according to ANSI/AMCA 210-16 and ISO 5801 standards, our test chamber can perform several types of performance testing on fans, impellers and machineries that employ fan-motor systems. Having in-house testing enables us to accelerate the design of new products, and makes it easier to test the performance of prototypes and products under development. Our test chamber is also available to our customers for testing their products and generating detailed test reports. Main characteristics of our chamber: • AMCA Fig. 15 – inlet chamber • Axial fans...

AMCA test chambers design and construction We support our customers in the design, construction and erection of AMCA 210 / ISO 5801 test chambers. Test chambers are very accurate tools to measure the performance of any air moving products, like impellers, ventilators, and “fan-using” products (engine cooling systems, HVAC, etc.), and the performance of passive products/parts (filters, dampers, etc.) through an airflow. Our engineers are here to accommodate all the specific requirements of our customers and provide highly customized solutions. Qualyfan selection software Qualyfan contains a complete...
