Collection: Ventilation Accessories

Ventilation accessories

Ventilation accessories are the components that complete and optimise a grow room ventilation system once your fans, carbon filter and ducting are in place. This collection covers hangers, clamps, duct joiners, diffusers and timers — the fittings that mount, connect, seal and automate your setup for consistent airflow.

Optimise Indoor Ventilation

A ventilation system is only as effective as its weakest connection. Loose ducting joints let conditioned air escape before it reaches your plants, improperly suspended fans vibrate and wear faster, and without a timer, fan cycles depend on manual switching that is easy to forget at a critical point in the grow. The right accessories lock the whole system together and keep it running reliably.

What's in this collection

Adjustable rope hangers and mounting brackets for fans and filters

Ducting clamps and jubilee clips for airtight connections

PVC duct connectors, Y-joiners and elbows for splitting or redirecting airflow

Inline air diffusers to eliminate hot spots and humidity pockets

Mechanical and digital timers for automated fan cycles

How to choose

Match hangers and clamps to your equipment

Match each accessory to your actual equipment rather than buying generically. Hangers need a weight rating suited to what they're carrying, especially heavy carbon filters, since undersized hangers are a common cause of equipment failure. Clamps need to match your ducting diameter exactly — most Australian grow rooms run 100mm, 125mm, 150mm, 200mm or 250mm ducting.

Choose the right joiner and timer type

For joiners, straight connectors suit two same-diameter ducts, Y-joiners split or merge airflow across multi-light or multi-room setups, and elbow fittings create smooth bends without collapsing the duct. If you're just starting out, a mechanical timer is a reliable, low-cost way to automate simple on and off fan scheduling.
