Product Dewspiption
The Meibao GTF Series High Pressure Centrifugal Fan is a professional-grade corrosion-resistant ventilation solution engineered for handling corrosive acid and alkali gases requiring elevated static pressure. Featuring a pure fiberglass reinforced plastic (FRP) construction for the casing, inlet bell, and impeller, this series completely eliminates the traditional carbon steel with FRP lining manufacturing process, providing superior corrosion resistance, durability, and long service life. The fan is designed for applications requiring higher pressure than standard medium and low pressure fans, delivering stable air volume and pressure with high operational efficiency. With a double-layer base design that allows maintenance without removing anchor bolts, and fully encapsulated connecting bolts to prevent corrosion damage, the GTF series is the ideal choice for chemical, electroplating, wastewater treatment, and environmental protection applications requiring high-pressure gas handling.
Key Features
High Pressure Performance
Specifically designed to deliver elevated static pressure (up to 4,500 Pa) for applications requiring higher resistance to overcome system pressure losses in complex ductwork and purification equipment.
Pure FRP Construction
The casing, inlet bell, and impeller are all made from pure fiberglass reinforced plastic (FRP), completely changing the traditional carbon steel with FRP lining manufacturing process. This provides uniform, dense corrosion protection with no risk of peeling, ensuring long-term resistance to acid and alkali gas erosion.
Fully Encapsulated Bolts
The connecting bolts between the casing and the iron frame are treated with a fully encapsulated method, completely isolating corrosive gases from metal bolts. This solves the industry-wide problem of bolt corrosion damage and ensures long-term structural stability.
High Efficiency & Energy Saving
Certified to China Energy Conservation Level 1 standard and AMCA certified, the fan delivers stable air volume and pressure with high operational efficiency. Paired with high-efficiency brand motors, it significantly reduces electricity costs during continuous operation.
Low Vibration & Low Noise
The fan features optimized aerodynamic design, precision dynamic balancing, and a double-layer base with spring shock absorbers. This ensures low vibration and noise during operation, meeting ISO-2372 4.5 level standards.

Typical Applications
Chemical Industry: High-pressure exhaust of corrosive acid and alkali gases, VOC system ventilation, and solvent recovery.
What is the maximum viscosity the MB pump can handle?
+
The MB magnetic drive pump is optimized for low-to-medium viscosity liquids (up to ~200 cPs at operating temperature). For high-viscosity media above 200 cPs, please contact our engineering team — we may recommend a reduced speed operation or a gear pump alternative.
Can the MB pump handle HF acid?
+
Yes. The MB pump with PTFE or PVDF wet-end is fully compatible with hydrofluoric acid at concentrations up to 50% and temperatures up to 80°C. PTFE offers the best HF resistance. For semiconductor-grade HF applications, we recommend our dedicated HF Series with ultra-pure material specifications.
What is the pump's NPSH requirement?
+
NPSH requirements vary by model and operating point. Typically, the MB series requires 2-3m NPSHa. We recommend ensuring the available NPSH (NPSHa) from your installation is at least 1m higher than the pump's required NPSHr. Full NPSH curves are available in the product datasheet.
Do you offer ATEX / explosion-proof versions?
+
Yes. ATEX Zone 1 and Zone 2 certified models are available for environments where flammable gases or vapors may be present. Please specify the ATEX zone and gas group (IIA, IIB, or IIC) when requesting a quote.
Can I get spare parts for this pump?
+
Yes. We stock a comprehensive range of spare parts for the MB series including magnet assemblies, impellers, shaft sleeves, and containment shells. Parts can be shipped within 5-10 working days to most destinations. We recommend ordering a spare parts kit with your initial order for critical applications.
