Product Overview: F4-72/79 High Temperature Fiberglass Centrifugal Fan

A professional manufacturer from China specializing in the design, manufacturing, and service of FRP fans, made of fiberglass material, corrosion-resistant, and high-strength! Enhanced safety structure and low vibration.

Perform computer stress-strain analysis on the entire unit to improve structural strength.
The impeller dynamic balance complies with ISO-1940 G2.5 grade.
The vibration value of the fan unit meets or exceeds the ISO-2372 4.5 level requirements, significantly reducing the risk of machine failure due to vibration and providing you with a safer working environment.

Durable to ensure longevity
FRP impeller is integrally formed, with rigidity and reduced strength equivalent to steel, and can be used for a long time.
The casing is made of Vinglester grade premium resin and is protected by a UV resistant rubber shell. The rubber shell has been tested and certified by the Lloyd's Shipbuilding Association in the UK, and has been subjected to seawater impact for 5 years to ensure that it will not fall off or deteriorate, ensuring its service life.

Good maintenance using oil bath bearings, maintenance personnel are free from burden
A complete product information book, with all spare parts, consumables, performance, operating range, etc. documented and listed.
Adopting oil bath connected bearings and enclosed oil tanks, the bearings and shafts are protected from corrosion by acidic and alkaline gases, prolonging their service life and reducing the frequency of failures.
Provide a fan maintenance manual to standardize maintenance work, retain maintenance records, and facilitate handover.
Modular production, unified specifications, complete and complete parts and consumables, can complete maintenance in the fastest time and at the lowest cost.
The humanized design of the bearing box facilitates maintenance and oil change.
Manhole configuration for the casing, clean the impeller, and inspect for dirt accumulation to avoid trouble.

1、 Introduction to Tianhong Commissioned Experimental Laboratory (a large domestic wind turbine inspection laboratory):

1: Our laboratory has passed the qualification review of the Energy Efficiency Labeling Management Center of China National Institute of Standardization and obtained the qualification of Energy Efficiency Testing Laboratory for Ventilation Fan Energy Efficiency Labeling. After the fan products are tested by the center, they can be directly registered online and labeled with energy efficiency labeling based on the test report, and then produced and sold.

2: Our laboratory has 198 quality inspection projects for fan products, and the parameters have passed national laboratory accreditation and metrological certification.

2、 The power performance and noise testing laboratory ensures the accuracy of the results through the following methods:

1. Strictly follow standards such as ISO 5801 (GBT 1236), ISO 13350 (GBT 19843), ISO 5802 (GBT 10178) for design, construction, and testing operations;

2. The aerodynamic performance test adopts advanced multi nozzle method, replacing the traditional pitot static pressure tube to test flow rate, further improving accuracy;

3. The laboratory extensively uses new precision testing equipment and measuring devices;

4. Laboratory equipment and measuring tools have undergone strict calibration and regular re inspection and self calibration;

5. Multiple national level laboratories in China have conducted multiple "same machine inter laboratory comparisons" and participated in the capacity verification activities of ventilation fan testing laboratories carried out by national institutions.

3、 In addition to aerodynamic performance and noise detection functions, the laboratory also has the following testing capabilities:

1. Conduct impeller overspeed test according to JB/T 6445 Industrial Ventilation Fan Impeller Overspeed Test.

2. Conduct fan vibration testing in accordance with standards such as JB/T 8689 "Vibration Testing and Limits for Ventilators".

3. Conduct thrust testing on tunnel jet fans in accordance with the ISO 13350 standard for performance testing of industrial ventilation fans and jet fans.

Ensuring the efficiency of Tianhong's product research and development, reliable quality control, and improving the accuracy and authenticity of technical data.
