Frequently Asked Questions

Q: What is the main advantage of a centrifugal fan over an axial fan for inline duct applications?

A: The primary advantage is the ability to generate higher static pressure. Axial fans are excellent for moving large volumes of air with little resistance (like in a free-standing exhaust scenario). However, once installed in ductwork with filters, elbows, and long runs, system resistance increases. Centrifugal fans, especially the backward-curved type used in our High Volume Inline model, are specifically designed to overcome this resistance efficiently, maintaining designed airflow where an axial fan's performance would drop off significantly.

Q: Can this fan be used for both supply and exhaust applications?

A: Absolutely. The High Volume Inline Centrifugal Fan is bidirectional in function. Its performance is symmetric, making it equally effective for pushing clean air into a space (supply) or pulling contaminated air out (exhaust). The installation orientation (horizontal or vertical) does not affect its performance, only the specific mounting arrangements required.

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

A: Proper selection requires knowing two key system parameters: the required airflow (in CFM or m³/h) and the total static pressure of your duct system (in inches of water gauge or Pascals). You can then plot this point on the fan's performance curve (provided in our detailed datasheets) to ensure it operates at its peak efficiency. Our technical sales team is always available to assist with this process based on your project details.

Q: What maintenance does this fan require?

A: Designed for low maintenance, the primary tasks are periodic visual inspections and cleaning of the impeller and housing interior to prevent dust buildup that could imbalance the wheel. The permanently lubricated, sealed bearings are designed for long life and typically do not require routine greasing. It is recommended to check mounting bolts and electrical connections periodically as part of a general facility maintenance schedule.

Q: Are variable speed drives compatible with these fans?

A: Yes, most models are well-suited for use with Variable Frequency Drives (VFDs). Using a VFD allows you to precisely control the fan speed (RPM), thereby tuning the airflow and pressure to exact demand, which can result in substantial energy savings. It is important to ensure the motor is inverter-duty rated if used with a VFD, and we can supply models configured for this purpose.

Q: What is the typical lead time for an order, and do you offer custom configurations?

A: Hebei Ketong maintains strategic stock of popular models for shorter lead times. For standard catalog items, lead times are typically competitive. We strongly specialize in custom configurations—including special sizes, materials, paints, motors, and accessories. While custom projects have longer lead times, we work closely with clients to define specifications and provide realistic timelines to meet project schedules.
