Extractor Fan Types

Standard Axial Fans

• Most common option
• Compact design
• Suitable for short ductwork
• Adequate for average bathrooms
• Good value for money

In-Line Centrifugal Fans

• More powerful option
• Handles longer/higher friction ductwork
• Quieter than axial fans
• Better for multi-room ventilation
• Premium pricing

Humidity-Controlled Fans

• Automatic operation based on moisture levels
• More efficient than timer-only systems
• Prevents over-ventilation
• Saves energy
• Recommended for bathrooms

Timer-Controlled Fans

• Run for set duration after activation
• 15-30 minutes typical
• Ensures sufficient ventilation
• Cost-effective option
• Available with humidistats

Inline Duct Fans

• Mounted within ductwork
• Quieter operation
• Better for longer runs
• More expensive
• Professional installation required

Ductwork Considerations

Proper ducting is essential for effective ventilation:

Duct Materials

• Flexible plastic ducting (common, adequate for short runs)
• Rigid metal ducting (more efficient, better for long runs)
• Insulated ducting (prevents condensation in duct)
• IP54 rated for bathroom use

Duct Sizing

• Must match fan output (CFM/m³h)
• Undersized ducts reduce efficiency
• Oversized ducts waste space
• Professional sizing essential

Duct Routing

• Shortest practical route to exterior
• Minimal bends to reduce friction
• Avoid horizontal runs (traps condensation)
• Slight downward gradient if necessary
• Sealed connections prevent leaks

Discharge Points

• External wall or roof termination
• Damper flap prevents back-draft
• Termination cap essential
• Must not discharge into soffits
• Coastal locations (salt air consideration)

Installation Process

1. Site assessment - Evaluate room size, moisture sources, ductwork route
2. Fan sizing - Calculate required CFM/m³h for space
3. Type recommendation - Select appropriate fan model
4. Ductwork planning - Design efficient routing to discharge point
5. Electrical assessment - Determine circuit requirements
6. Installation - Professional fan and ducting installation
7. Duct sealing - Ensure proper connections and weatherproofing
8. Testing and adjustment - Verify operation and airflow

Airflow Requirements

Correct fan sizing depends on room size and moisture level:

Bathroom Ventilation

• Small bathroom (2-3m²) - 50-75m³/h
• Average bathroom (4-6m²) - 75-100m³/h
• Large bathroom (7-10m²) - 100-150m³/h
• Ensuite (2-4m²) - 50-75m³/h

Kitchen Ventilation

• Small kitchen area - 150-200m³/h
• Average kitchen - 200-300m³/h
• Large kitchen/diner - 300-400m³/h
• Commercial-style cooking - 400+m³/h

Calculation Formula

• Multiply room length × width × height × air changes per hour (8-10 for bathroom, 6-10 for kitchen)

Common Installation Issues

• Undersized fans - Inadequate ventilation of moisture
• Poor ductwork routing - Long runs, bends, horizontal sections reduce efficiency
• Missing dampers - Back-draft allows air back into room
• Inadequate ducting - Reduces airflow and creates noise
• No humidity control - Runs constantly even when not needed
• Inadequate electrical protection - Fire hazard from improper wiring

Maintenance After Installation

Extractor fans require regular maintenance:

• Grease filters (kitchens) - Clean or replace monthly
• Fan grilles - Clean quarterly to remove dust buildup
• Ductwork inspection - Annual check for blockages or damage
• Motor noise - Bearing lubrication may be needed if squeaking
• Damper operation - Ensure flap moves freely
• Electrical checks - Annual safety verification

Coastal Considerations

East Sussex coastal properties require special attention:

• Salt air corrosion - Use stainless steel components
• Higher humidity - May require stronger ventilation
• Corrosion prevention - Coated metals and sealed components
• Moisture extraction - Critical in coastal damp environments
• Regular maintenance - More frequent cleaning needed

Service Coverage

Available throughout Eastbourne, Brighton, Hastings, Lewes, Hailsham, and all East Sussex locations. We handle residential properties of all ages and styles.
