Frequently Asked Questions

Q: What is the main difference between a Type F (forward-curved) and a Type B (backward-curved) centrifugal fan?

A: The key difference lies in the blade design and performance characteristics. Type F fans have many short blades curved in the direction of rotation. They are excellent for moving high volumes of air at relatively low to medium static pressures and are typically more compact and cost-effective for these duties. Type B fans have fewer, longer blades curved against rotation. They are more efficient at higher static pressures and are often preferred for clean air applications in large HVAC systems or for handling high-temperature gases. The Type F is generally the go-to choice for industrial ventilation and dust collection.

Q: Can your Type F fans handle hot air or gases?

A: Yes, but within specified limits. Standard models with belt drives and standard bearings can typically handle temperatures up to 250°F (120°C) continuously. For higher temperatures, we can configure fans with high-temperature belts, special lubricants, heat shields, and even different bearing arrangements. It is crucial to inform us of the maximum operating temperature during inquiry so we can propose the correct construction.

Q: How noisy are these fans in operation?

A: Noise level depends on the fan size, speed, and operating point. Our Type F fans are designed with aerodynamically efficient blades and precision balancing to minimize turbulence and vibration, which are primary noise sources. While they are not silent (no industrial fan is), they operate at sound pressure levels competitive with industry standards for their performance class. For critical noise-sensitive areas, we can offer optional acoustic enclosures or inlet silencers.

Q: What maintenance is required?

A: Maintenance is straightforward but essential for long life. The primary tasks include periodic checking and tensioning of drive belts (for belt-drive models), lubricating bearings according to the manufacturer's schedule (typically every 8,000-12,000 hours of operation), and regularly inspecting/cleaning the impeller and housing interior to prevent heavy buildup of material, which can imbalance the fan. Our manuals provide detailed maintenance schedules and procedures.

Q: Do you provide installation support or guidance?

A: Absolutely. We provide comprehensive installation manuals with each unit, covering foundation requirements, alignment procedures, electrical connections, and safety checks. For complex installations or large projects, our engineering team is available for technical consultation. While we typically do not provide on-site installation crews globally, we can recommend best practices and connect you with qualified local mechanical contractors if needed.

Q: How do I select the right size and model for my application?

A: Proper selection requires knowing your system's required airflow (in CFM or m³/h), the static pressure it must overcome (in inches of water gauge or Pa), the temperature and nature of the air (clean, dusty, corrosive), and any space constraints. We strongly recommend consulting with our technical sales team. Provide them with your system details or layout, and they will perform a selection analysis, recommend the optimal model, and provide a performance curve showing the expected operating point.

Q: What is your lead time and warranty policy?

A: Lead times vary based on model complexity and order volume. Standard configurations often have shorter lead times, while custom-built units require more. Please contact us for a current estimate. Our standard warranty covers defects in materials and workmanship for a period of 18 months from the date of shipment or 12 months from commissioning, whichever comes first.
