Extractor Fan Units NZ

Our range covers ceiling extractor fan units, inline extractor fan units, and exhaust fans for domestic, commercial and light industrial jobs, stocked in our nationwide branches for trade and DIY buyers.

Choosing the Right Extractor Fan for the Job

A ceiling extractor fan fits into the ceiling and suits bathrooms with short, straight duct runs. An inline extractor fan sits further along the ducting, away from the wet area, so it's better for longer runs, extracting from more than one room, or where you want less fan noise near the room itself.

As a guide, a longer or bendy duct run will cut down what the fan actually delivers, so you may need a stronger fan than a straight run would suggest. Fans fitted close to a bath or shower must also be water-resistant.

Extractor Fan FAQs

What size extractor fan do I need for my bathroom?

Sizing depends on the room's volume, function and duct length, not just floor area. 

Longer or bent duct runs reduce the airflow the fan actually delivers, so a fan on a long run typically needs a higher-rated unit to still hit that figure. Confirm requirements with a registered electrician.

Can I install an inline extractor fan myself?

Wiring in a bathroom is prescribed electrical work and must be carried out by a registered electrician.

Does ducting length affect fan performance?

Yes, every metre and bend adds resistance, so long or heavily bent runs generally need a higher-capacity inline fan rather than a standard ceiling unit.

Do you stock ducting and accessories to match these fans?

Yes, ducting, roof cowls and duct fittings are stocked separately for a complete installation.
