Description

F4-72 Type A Series FRP Centrifugal Fan

The F4-72 Type A Series FRP Centrifugal Fan adopts the mature performance parameters of the classic metal 4-72 centrifugal fan, and is integrally manufactured with high-performance FRP (fiberglass reinforced plastic) composite material. It is specially developed for conveying acid, alkali and other chemically corrosive gases, widely applied in chemical plants, electroplating workshops, oxidation workshops, power plants, laboratories, circuit board production workshops, environmental protection equipment and other scenarios with corrosive gas emission demands.

F4-72-A Model Features

Material & Structural Properties

  • The whole fan shell and flow-passing components are made of FRP composite material, featuring outstanding acid & alkali corrosion resistance, anti-aging performance and light weight.
  • It inherits the aerodynamic structure of the original 4-72 metal fan: the impeller is equipped with backward-curved wing-type blades, passing strict static and dynamic balance calibration, to achieve high efficiency and stable operation.
  • Models from 2.8A to 7A adopt fixed integrated casing that cannot be disassembled, with fixed curved side air inlets containing axial parallel sections, which can guide air into the impeller smoothly to improve ventilation efficiency.
  • It adopts direct-coupled drive motor (B35 type with flange and footing for A-type models), with compact structure, low mechanical vibration and low running noise.

Core Advantages

  • Excellent Corrosion Resistance: FRP material can resist most conventional acid, alkali and salt corrosive gases, which solves the rust and failure trouble points of ordinary steel fans in corrosive working conditions.
  • Stable Aerodynamic Performance: Optimized impeller and air duct design brings high working efficiency, flat pressure curve and low noise output.
  • Long Service Life: The material has great anti-aging ability, suitable for long-term continuous operation in high-humidity corrosive environments.
  • Easy Installation & Maintenance: Integrated fixed structure matches standard duct sizes, and the direct-drive structure reduces intermediate transmission parts for simpler daily maintenance.

Transport Medium Restrictions

The conveyed gas cannot contain sticky substances; the concentration of dust and hard solid particles in the gas shall not exceed 150mg/m³, gas temperature ≤60℃, relative humidity ≤100%. It cannot be used for flammable & explosive gas conveying by default (explosion-proof customized motor is required for such scenarios).

Model Selection

This series covers models from 2.8A to 7A, with matched power ranging from 0.75kW to 11kW, rotating speed options of 1450r/min and 2900r/min, to meet different airflow and total pressure demands.
Model Power(kW) Rotation Speed(r/min) Air Flow(m³/h) Total Pressure(Pa)
2.8A 0.75 / 1.5 1450 / 2900 566~1060 / 1131~2120 297~103 / 994~606
3.2A 1.1 / 2.2 1450 / 2900 844~1582 / 1688~3165 324~198 / 1300~792
3.6A 1.1 / 3 1450 / 2900 1332~2371 / 2664~4741 393~247 / 1578~989
4A 1.1 / 5.5 1450 / 2900 2006~3338 / 4012~6677 501~329 / 2014~1320

7A 7.5 / 11 1450 / 1450 8500~17500 / 10602~19083 1200~600 / 1550~984

Q1: What are the main application scenarios of F4-72 Type A FRP centrifugal fan?
A1: It is mainly used for corrosive gas ventilation and exhaust in chemical industry, electroplating, oxidation workshops, power plants, laboratories, circuit board factories, environmental protection supporting equipment and other places with acid-alkali corrosive fumes.
Q2: What is the essential difference between F4-72 and the ordinary 4-72 steel centrifugal fan?
A2: Ordinary 4-72 fans are made of steel plate/cast iron, easy to corrode in acid-alkali environment; while F4-72 uses FRP composite material, which has excellent corrosion resistance for long service life in corrosive working conditions, with identical aerodynamic parameters and installation dimensions as 4-72 series.
Q3: What limits are there for the gas that this fan can convey?
A3: The gas can't have sticky substances; dust & hard particle concentration ≤150mg/m³, gas temperature ≤60℃, relative humidity ≤100%. It is not suitable for flammable/explosive gases without explosion-proof customization.
Q4: Can this fan work in high-humidity workshop environments?
A4: Yes, it can adapt to relative humidity up to 100%, the FRP material will not get rusty like steel fans under long-term damp conditions.
Q5: Can I use this fan for 24-hour non-stop continuous production operation?
A5: Sure. The impeller has passed strict static & dynamic balance correction, with small vibration and stable operation; the aging-resistant FRP structure is designed to support long-term continuous running.
Q6: What type of motor is equipped for the 2.8A-7A A-type models?
A6: Models 2.8A to 7A adopt B35 type motor with flange plate and footing for direct drive. If you need explosion-proof function, we can customize YB series explosion-proof motors for you.
Q7: How do I pick the exact model for my project?
A7: First confirm your required airflow (m³/h) and total pressure (Pa), as well as gas corrosive components, temperature and dust content. You can send these parameters to our technical team, we will recommend the most suitable model and rotating speed for you.
Q8: Is the fan casing detachable for deep cleaning?
A8: For 2.8A-7A A-type models, the casing is fixed non-detachable structure, you can clean the interior through the air inlet and outlet easily in daily use.
Q9: Can this fan handle high-temperature gas over 80℃ like stainless steel F4-72 version?
A9: No. This FRP A-type fan's maximum allowable gas temperature is 60℃. For gas temperature above 80℃, you need to choose the stainless steel F4-72 variant.
Q10: What after-sales services can you provide for overseas orders?
A10: We will provide detailed English installation, operation and maintenance manuals together with goods. We offer online technical guidance all the time, and support spare parts supply for long-term after-sales maintenance.
