Buying Guide

Match fan size to duct diameter

Choose inline fans and ducting that share the same inch measurement (e.g., 4", 6", 8", 10") to avoid airflow loss and leaks

Consider EC motors for efficiency

Fans with electronically commutated (EC) motors deliver better energy efficiency and finer speed control than basic AC motors

Use carbon filters for odor control

Pair inline fans with appropriately sized carbon filters to remove odors and particulates in closed greenhouse or grow-tent setups

Prioritize noise reduction

Look for duct silencers, mufflers, or fans marketed with noise-reduction features to keep greenhouse ambient levels low

Durable ducting for long runs

Opt for multi-layer, aluminum-foil or reinforced ducting for longer ventilation runs to prevent tears and maintain airflow
