L series - low pressure centrifugal fan

Product Parameters

*Parameter configuration is subject to modification without prior notice*

Product Advantages

1. The fan has high efficiency: it adopts binary flow design software combined with fluid mechanics to design, and it can be customized for customers.

2. Low vibration of the fan: the complete machine balance test software imported from Sweden is perfectly combined with the acquisition card of the American NI company so that the amplitude of the fan machine is less than 3mm/s as the factory standard

3. Low noise: the fan volute is equipped with a special noise reduction device for the motor, which makes the overall noise of the fan better than similar domestic products

4. Less maintenance: The overall structure is different from similar domestic products, making the fanless or maintenance-free during use

5. Certification: Every fan we produce can pass the certification of the world's five major classification societies

6. Long life: Strict quality standards make our fan service life up to 20 years (except wearing parts)

Quality Workmanship

Set clear quality standards

The whole process of fan selection, design, manufacturing (including outsourcing processing), and delivery, formulate clear quality control standards

Quality Standard Execution

100% full inspection of raw materials, outsourcing processing, internal manufacturing process and finished product shipment

Product Traceability

The product has a unique identification code from the generation of the order, and this identification code runs through the entire product formation from raw material procurement, internal manufacturing, outsourcing processing, and the entire use cycle of the product after-sale

The effectiveness of detection means

The testing equipment is regularly sent to the Bureau of Quality and Technical Supervision for verification in accordance with the quality system requirements, and the effectiveness of all testing equipment is controllable

Design And Manufacture Of Impeller

Production of impeller

The impeller is the key component of the fan, and the key component of our fan is self-made. We understand the importance of key components in the fan. The quality of the impeller directly determines the efficiency and service life of the fan. The self-made process ensures the controllability of the quality of key components. The balance accuracy of the Rosenberg dynamic balancing machine is 0.5g.mm/kg, and the impeller is tested according to the ISO 1940 standard.

Motor Matching

A variety of motor specifications to meet the different needs of customers

The motor is the key part of all fans. We insist on providing customers with reliable brand motors. We have established long-term and close cooperative relations with various major brand motor manufacturers so that we can provide customers with more flexible choices. The motors used in our fans can meet any industry standards/requirements including IPSS and IP56.

Fan Housing

Our fan frame, shell, and air inlet are all monitored, which highlights the controllability of product quality and product delivery; at the same time, special process design and double-sided welding are adopted according to different places of use.

[Accessories]: air inlet grille, muffler, CP nozzle, import and export compensator, pad reduction, cooling plate, air valve

Detection And Correction

Rosenberg fan machine vibration implementation standards: I So14694:2003 and iso10816-3:1998 group1; machine vibration ≤ 2.5mm/s

Detection equipment: Imported Virbometer vibration detection software, American N9234 9216 data collector, American CTCAO115-1D three-axis vibration sensor, CEM AT-6 tachometer

Detection software: Vibrometer is a powerful and particularly high-accuracy wind turbine balance correction software; it can be adapted to various mechanical equipment for single- and double-sided balance calibration. The vibrometer complete dynamic balance test and calibration equipment consist of Swedish test core software, N data acquisition card, three-coordinate vibration sensor, and tachometer.

Advantages: The vibration of the whole machine is less than or equal to 25mm/s, and the service life of the fan (especially the bearing) is extended, the noise is reduced, and the fan is more energy-saving

Wind parameter measurement of wind turbines: The balance calibration software from Sweden combined with the data collector from National Instruments can ensure that the dynamic balance of wind turbines is within 3mm/s. The imported whole machine vibration detection equipment can detect the AHV three-dimensional vibration at the same time, and accurately calculate the balance compensation amount, which makes our fan machine balance level higher than the national standard, higher than the peers, and the fan service life is significantly extended. All the fans we produce must meet the "GB10178-2006" and design standards through wind data testing.

Impeller balance correction: Impeller balance is an indispensable link in the fan production process. We use dynamic balancing machines from well-known manufacturers, and the balance accuracy is 0.5gmm/kg. The impeller is 100% tested according to the 1501940 standard, and the impeller tests are recorded and tracked
