The LARGE plastic reducer from BloomLED is the clever fitting to link an extractor fan, a carbon filter and ducting of different diameters. Built for indoor growing, it creates a clean, airtight junction between your Ø 160 and 150 mm sections for controlled, quiet airflow.

| Material | Rigid plastic |
| Diameters | Ø 160 / 150 mm |
| Size | LARGE |
| Use | Indoor ventilation fitting |
Push the reducer onto your ducting and secure it with aluminium tape: no cutting, no complicated tools.
The gradual transition between the two diameters limits turbulence and noise for efficient stale-air extraction.
Made of lightweight rigid plastic, it can be removed and refitted whenever you change equipment without wear.
The LARGE model adapts a Ø 160 mm section down to Ø 150 mm, the most common diameters for indoor extractors and filters.
How do I make the joint airtight?Push-fit the reducer, then wrap the junction with aluminium tape: this blocks air leaks and odour loss.
A small accessory under €4 that keeps the ventilation in your grow tent efficient, airtight and quiet.
