Mixed Flow Fans: Dwell Air's Complete Guide to Inline Ventilation Solutions

What Are Mixed Flow Fans? Understanding the Hybrid Ventilation Technology with Inline Mixed Flow Fan

Mixed flow fans represent a breakthrough in ventilation engineering, combining the high airflow capacity of axial fans with the pressure-building capabilities of centrifugal fans. Unlike traditional fans that move air in a single direction, mixed flow fans create a unique dual-flow pattern where air moves both axially (parallel to the shaft) and radially (perpendicular to the shaft), delivering superior performance with reduced noise levels.

This hybrid design makes mixed flow inline fans the ideal choice for applications requiring balanced airflow rates between 200-2000 CFM with moderate static pressure (0.2-1.5 inches of water column), operating at significantly lower decibel levels than comparable axial or centrifugal alternatives.

Dwell Mixed Flow fans are not only for exhaust ventilation but because of their high airflow and smart design, they also help for supply or fresh air flow fans in any setting, making them versatile and low noise fans with low energy consumption.

How Mixed Flow Fans Work: The Engineering Behind Superior Performance

The secret to mixed flow fan efficiency lies in its specially designed impeller blade geometry. The blades are positioned at optimized angles that guide air through a sophisticated flow path:

Airflow Mechanics:

Air enters axially through the inlet, similar to traditional inline fans
The impeller's unique blade curvature gradually redirects airflow in a radial direction
This dual-flow pattern creates higher pressure differential while maintaining smooth, continuous airflow
The result: 40% more efficient operation compared to standard axial fans with 50% less noise

Key Performance Advantages:

Static Pressure Range: 0.2 to 1.5 inches water column (ideal for ductwork systems)
Efficiency Ratings: 65-75% peak efficiency vs 50-60% for axial fans
Noise Reduction: 15-25 dB lower than equivalent CFM axial fans
Compact Installation: Same footprint as inline axial fans with centrifugal-level performance

When to Choose Mixed Flow Fans

Choose Mixed Flow When:

Ductwork systems require moderate static pressure but high air flow (0.2-1.5" WC)
Noise levels are a critical concern (residential, office spaces)
Space constraints require inline installation
Energy efficiency impacts operating costs
Balanced airflow and pressure are both important
Installation budget is moderate
Need Supply and Exhaust requirements and where fresh air with filter box is required

Choose Axial Fans When:

Very high airflow is needed with minimal static pressure
Open-air applications (no ductwork)
Budget is primary constraint
Noise is not a concern
Simple on/off operation is sufficient

Choose Centrifugal Fans When:

High static pressure is critical (>1.5" WC)
Handling dirty or particulate-laden air
Very long duct runs or complex duct systems
Precise airflow control with VFD is required
Space for separate fan housing is available

How to Size and Select the Perfect Mixed Flow Fan

Step 1: Calculate Required CMH (Cubic Meter per Hour)

For Room Ventilation: CMH = Room Volume in meters (Length × Width × Height) × Air Changes Per Hour (ACH)

Common ACH Requirements:

Residential bathrooms: 6-8 ACH
Commercial bathrooms: 8-10 ACH
Kitchens (residential): 15-20 ACH
Conference rooms: 4-6 ACH
Workshops: 6-12 ACH
Grow rooms: 30-60 ACH

Example Calculation:
Bathroom: 5' × 3' × 2.8' = 42 cu meter
Required ACH: 8 CFM Needed = (42 × 8) = 336 CMH
Recommended Fan Size: 150mm (rated 288-432 CMH) with buffer - Dwell Mix 150

Step 2: Determine Static Pressure Requirements

Static pressure depends on:

Total duct length
Number of elbows and bends
Filter resistance (if applicable)
Grilles and diffuser pressure drop

General Guidelines:

Short ducts (<10 feet, 1-2 bends): 0.2-0.4" WC
Medium ducts (10-25 feet, 2-4 bends): 0.4-0.8" WC
Long ducts (>25 feet, 4+ bends): 0.8-1.5" WC

Step 3: Select Fan Size Based on Performance Curves

Match your CMH and static pressure requirements to manufacturer performance curves:

Dwell Air Mixed Flow Fan Sizes and their CMH and other performance parameters summarized:

Dwell 100mm (4"): 80-120 CFM @ 0.2-0.6" WC
125mm (5"): 120-180 CFM @ 0.3-0.8" WC
150mm (6"): 180-300 CFM @ 0.4-1.0" WC
200mm (8"): 350-600 CFM @ 0.5-1.2" WC
250mm (10"): 600-950 CFM @ 0.6-1.4" WC

Mixed Flow Fan Installation Guide: Professional Methods for Maximum Performance

Pre-Installation Planning

1. Location Selection:

Install as close to exhaust/supply point as practical
Minimize duct length and bends
Ensure adequate access for maintenance
Verify electrical supply availability (typically 120V or 240V)
Consider vibration isolation for noise-sensitive areas

2. Mounting Orientation: Mixed flow fans can be mounted in any orientation:

Horizontal: Most common for wall penetrations
Vertical: Ideal for stack effect applications
Angled: Custom installations for architectural requirements

Installation Steps

Step 1: Ductwork Preparation

Use rigid metal or semi-rigid aluminum ducting (preferred over flexible)
Maintain recommended duct diameter (never reduce below fan outlet size)
Keep duct runs as straight as possible
Use long-radius elbows (not 90° sharp bends)
Seal all connections with aluminum HVAC tape (not cloth duct tape)

Step 2: Fan Mounting

Use supplied mounting brackets or suspension hardware
Install vibration isolation mounts for ultra-quiet operation
Ensure fan is level (verify with spirit level)
Maintain 6-12 inches clearance before and after fan for optimal airflow

Step 3: Electrical Connection

Follow local electrical codes (NEC in USA, IS standards in India)
Use dedicated circuit for larger fans (>500W)
Install appropriate overcurrent protection
Consider speed controller installation for variable operation
Ground chassis properly to electrical ground

Step 4: Airflow Direction

Verify arrow on fan housing indicates correct flow direction
Most exhaust applications: airflow arrow pointing away from room
Supply applications: airflow arrow pointing toward room
Booster applications: match ERV system flow direction

Step 5: Testing and Commissioning

Power on fan and verify rotation (listen for smooth operation)
Check for vibration or rattling (indicates improper mounting)
Measure airflow with anemometer or flow hood
Verify noise levels meet specifications
Test control switches and automation if integrated

Common Installation Mistakes to Avoid

Critical Errors:

❌ Installing fan immediately after sharp 90° bend
❌ Using undersized ductwork creating backpressure
❌ Flexible duct stretched to maximum length (causes restriction)
