Frequently Asked Questions
Common Questions About Tubular Type Fan
Find answers to the most common questions asked by our clients.
A tubular (tube-axial) fan is an axial flow fan housed within a cylindrical tube/duct section rather than panel/wall mounted. Design features: Inline configuration: Mounts directly within ductwork with flanged connections both ends. Enclosed impeller: Blades enclosed in metal tube optimizing airflow efficiency. Streamlined housing: Aerodynamic inlet bell and outlet diffuser reduce turbulence losses. Higher efficiency: 65-75% versus 50-60% for panel axial fans due to controlled airflow path. Higher pressure: Can generate 75-200 mmWC versus 25-75 mmWC for panel types. Applications: Inline ventilation systems, duct boosting, bypass installations, paint booth supply, clean room air circulation where ductwork exists and moderate pressure needed economically versus centrifugal fans.
Tubular Axial: Straight-through airflow, pressure 50-200 mmWC, efficiency 65-75%, lower noise, simpler construction, 30-50% lower cost. Centrifugal Inline (plug fans): Right-angle airflow turn inside housing, pressure 100-400 mmWC, efficiency 70-80%, higher noise, more complex scroll design, higher cost. When to choose tubular: Straight duct runs, pressure <150 mmWC, noise critical, budget limited. When to choose centrifugal inline: Pressure 150-400 mmWC, space for diameter but not length, need highest efficiency. Example: Fresh air intake duct boosting = tubular fan (straight run, low pressure). Dust collector inline exhaust = centrifugal inline (higher pressure needed). Both save space versus external blower with duct transitions.
Tubular fans range 200mm to 1600mm diameter, matching standard duct sizes: Small (200-400mm): 500-5,000 CFM, 50-120 mmWC, laboratory fume hood inline exhaust, small process ventilation. Medium (400-800mm): 5,000-30,000 CFM, 75-150 mmWC, commercial HVAC supply/return boosting, paint booth inline supply. Large (800-1600mm): 30,000-150,000 CFM, 100-200 mmWC, large building ventilation systems, industrial inline applications. Length: Typically 1.5-2.5× diameter (much shorter than centrifugal equivalent). Installation note: Fan diameter must match existing ductwork diameter exactly for proper installation and performance - cannot adapt significantly different sizes. Pressure varies with blade pitch/speed - specify both CFM and pressure requirements for proper selection.
Yes, vertical installation fully supported with considerations: Airflow direction: Verify motor cooling adequate - upflow preferred (motor in cooler upstream air versus hot downstream). Some motors rated for any orientation, others require minimum airflow for cooling regardless of orientation. Mounting: Requires proper support brackets attached to building structure, not relying only on duct flanges. Use hanger rods or support frame carrying full fan weight plus vibration loads. Drainage: Install condensate drain port at lowest point if handling humid air (prevents water accumulation in housing). Access: Ensure adequate clearance for motor/bearing maintenance - typically need 600mm access space. Vibration isolation: More critical in vertical installations - use spring isolators sized for vertical orientation. Backdraft prevention: Install motorized damper if backflow concern when fan off. Most installations successful but requires more installation planning than horizontal.
Streamlined maintenance: Monthly: Visual inspection through access panels, check vibration levels (touch housing), verify motor current normal, inspect inlet screen for blockages. Quarterly: Bearing lubrication if grease fittings (2-3 grease gun pumps NLGI Grade 2), belt tension check if belt-driven (most are direct-drive), measure vibration with instrument (<4.5 mm/sec RMS). Semi-annually: Blade cleaning through access door - dust buildup reduces efficiency significantly. Motor insulation resistance test. Inspect flexible duct connections for deterioration. Annually: Bearing replacement (preventive for 24/7 operations), complete blade/impeller inspection for cracks or damage, motor winding condition assessment. Advantage: Direct-drive tubular fans have excellent reliability - simple design, minimal moving parts. Access consideration: Requires duct disconnection for major service versus simple inspection door on housed fans - plan maintenance windows accordingly for critical systems.
