Continental Fan’s Terms and Conditions of Sale. Please be aware that we are not responsible for the content or privacy practices of such other sites. The optimum operating area for a backward curved centrifugal fan is an area in the middle of its performance characteristic. As a rule of thumb if you can keep the smaller dimension to a minimum of 1.4 x the fan diameter then you will not go far wrong. Smaller blowers may have backward-inclined blades, which are straight, not curved. Technical description; Weight: 5.4 kg: Motor size: 84 : Size: 280 mm: Rotor surface: Painted black : Electronics housing material: Die-cast aluminum : Impeller material The most significant effect will be an increase in noise at blade passing frequency (I have seen this in one application that made the fan sound like an air powered siren - for an example of this type of sound see https://www.youtube.com/watch?v=xhWUUblpDZA) TEK Airfoil Impellers – Backward Curved Description.

Fan Types – Why Choose a Backward Curved Centrifugal fan? Continental Fan may make changes to the materials contained on its website at any time without notice. The volume flow rate, (in m3/hr) and the pressure (in Pascals - Pa), are combined to become the duty point against which the fan must operate. If there is anything else please let me know A backward curved plug fan being selected at medium flow medium pressure where the duty point ratios could be from For an axial fan you need to ensure that the impeller does not operate in aerodynamic stall or exhaust side of the fan, the volume flow rate will drop. Continental Fan has not reviewed all the sites linked to its website and is not responsible for the contents of any such linked site. The air intake and flow channel geometries are the outstanding features of RadiCal impellers. 10,000m3/hr @ 120Pa impeller is also called the backward curved impeller, and the backward impeller is mainly medium pressure. In order to use this website, you must complete the registration form and provide certain information. Over the last 20 years centrifugal fans with backward curved blades have become more common within air handling. This turbulence will be increased as the air passes through the impeller which makes the transfer of energy from the fan blade to the air less efficient, cause the creation of more noise and reduce the fan efficiency. The backward curved centrifugal fan design uses the centrifugal force generated by a rotating disk, with blades mounted at right angles to the disk, to impart movement to the air or gas and increase its pressure. Using an inlet ring (Inlet nozzle) overlapping the impeller inlet cone will help to eliminate flow disturbances before the air is drawn through the fan, reduce turbulence induced noise, keep the power consumption at the duty point to a minimum and maximise efficiency. How you can correct any inaccuracies in the information. The non-overloading characteristic, the ability to install the fan with or without a scroll and an impeller design that offers the highest static efficiency of all types of fans means that the backward curved fan is a flexible, adaptable fan design can be used across a wide range of installations. Information Collection, Use, and Sharing, 2. In theory at least one of the dimensions could be right next to the impeller circumference and as long as the other was large enough the hydraulic diameter calculation will work.

Dan, Hello Peter, Impeller for backward curved fan from Dia 133 to Dia 500 mm 3. Similarly, placing an obstruction to flow close to the exhaust side of the fan will create turbulence and buffeting which will increase the resistance to flow which the fan will have to overcome. In this article, we will compare the difference between the two types of blades. Backward Inclined- The performance of the backward inclined wheel is similar to the forward curve, however BI fans tend to be non-overloading, meaning their fan curves do not tend to increase hp as static pressure changes, but cfm falls off. The name, ‘Centrifugal Fan’ is derived from the direction of flow and how the air exits the fan impeller radially from the outer circumference of the fan. It can have a high range of specific speeds but are most often used for medium specific speed applications—high pressure, medium flow applications. This airflow pattern provides the option of positioning the exhaust duct in a radial or in-line position.

These durable, backward curved airfoil wheels deliver fan performance approaching aerodynamic perfection. On the leading, convex side of the impeller blade, a positive pressure is created as the rotational motion of the impeller imparts a force in the air. So it can be your future reference when choosing industrial centrifugal fans. TEK Airfoil Impellers combine precision injection molding techniques with modern high strength plastics to produce a wheel that is stronger than steel, yet half its weight. With a backward curved impeller, the air exits in a radial direction whereas with a forward curved the air exits tangentially from the circumference of … 1000m3/hr @ 60Pa Centrifugal fans are offered with 115 V to 230 V power supply and 107 cfm to 1,324 cfm flow rate. Other fans such as axial, diagonal and forward curved centrifugal fans have areas in which operation is inadvisable. This information is used to contact you about the products/services on our site in which you have expressed interest. This air is then picked up by the following blade and forced outwards radially in a continuous process. Using a basic scroll reduces the velocity of the air and converts some of the dynamic pressure energy into static pressure which produces a steeper pressure characteristic. Hi Dan, $ 60.00 $ 45.00 Add to cart; 133mm 72mm Mini Industrial Ventilation Duct Fan/ Mini Centrifugal Fan Sale! Forward curved fans are usually limited in size which means the top end flowrate is lower than axial or backward curved High pressure centrifugal fans, forward & backward curved blades, industrial centrifugal fans, external rotor motor Backward curved motorised impellers also have the highest static efficiency of any fan type and the mechanisms used in creating the airflow through the fan mean that it can be equally used on its own in a basic plenum or it can be enclosed within a scroll to direct its airflow.

Backward curved impeller are much more energy efficient than radial blade fans and so, for high power applications may be a suitable alternative to the lower cost radial bladed fan. It is important that we select a fan whose performance characteristic meets the required duty point on or near the point of peak efficiency. Regards Terminology for Centrifugal Fan Components Fan Performance Characteristics of Centrifugal Fans Vector R represents the resultant velocity for each of these blade shapes. The forward curved centrifugal fan is smaller than the backward curved centrifugal fan. The name, ‘Centrifugal Fan’ is derived from the direction of flow and how the air exits the fan impeller radially from the outer circumference of the fan. However, forward curved CP are sometimes used when the fluid concerned is air, as in a centrifugal fan. The design is more accordant with the aerodynamic characteristics, and has lower noise, and stable airflow. It is important to ensure sufficient clearance on both the suction and exhaust sides of the fan. Continental Fan’s EC Backward Curved Motorized Impeller is a superbly crafted and precision balanced air-moving devices, featuring superior performance and compact design.
