150mm Aluminium Flexible Hose — Expands from 120mm to 3 Metres, Fire Retardant
This 150mm aluminium flexible hose is designed to connect directly from the motor unit outlet of a cooker hood to the start of the rigid ducting run. It expands from a compressed length of 120mm up to 3 metres, providing sufficient flexibility to bridge the gap between the motor spigot and the first rigid duct section, accommodating minor misalignments and motor vibration in the connection.
Fire Retardant — Why This Matters
Aluminium flexible hose is fire retardant and will not melt or shrink when exposed to the high temperatures produced during cooking and extraction. This makes it the only appropriate material for the section of ducting directly connected to the cooker hood motor. For maximum safety, always use aluminium flexible hose or rigid ducting for cooker hood installations — never plastic.
⚠ Never Use Plastic Washer-Dryer Hose on a Cooker Hood
White PVC washer-dryer hose must never be used as cooker hood ducting under any circumstances. PVC hose is not fire retardant — it will melt, shrink, and collapse when exposed to cooking temperatures, creating a serious fire hazard. Despite being a similar diameter to some cooker hood outlets, washer-dryer hose is completely unsuitable for extraction use. Always use aluminium flexible hose or rigid ducting throughout a cooker hood installation.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:
- Below 450m³/hr → 100mm (4") ducting
- 450–750m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2,000m³/hr → 150mm (6") or 200mm (8") ducting
The System150 6" Ducting Range
This hose is compatible with the Luxair System150 150mm round ducting range. The full System150 range includes rigid round and flat pipe sections, bends, elbows, connectors, adapters, and wall vents. Use ducting tape or a collar connector at joints where push-fit components are not used to ensure an airtight seal throughout the duct run.
