Description
ENVIRO ET30 AIR PUMP is the compact entry-level air pump from the Enviro range, designed for the smallest growing applications — single-propagation units, nano DWC setups, and nutrient mixing vessels up to 20 litres where a gentle, consistent trickle of dissolved oxygen is needed without the output or size of a full-scale grow room air pump. We have been supplying Enviro air pumps to UK growers since 2017 as a reliable, quiet range across all output tiers.
Where the ET30 Fits in Your Grow Room
The ET30 is the right pump for applications where budget and space are the primary constraints and a single small air stone is all the system requires. For a propagation cloner running a small central stone to maintain water circulation, a 10–15 litre mixing vessel where gentle solution movement prevents stratification, or a single small reservoir used as a supplemental oxygen source in a soil-based system’s feed reservoir, the ET30 provides adequate output without the wasted capacity and unnecessary electricity consumption of a larger pump. It runs quietly at minimal power draw and its compact size means it can be tucked in any spare space without occupying valuable growing real estate.
Maintenance and Reliability
The ET30 diaphragm should be checked annually — if output reduces noticeably after cleaning the air stone, the diaphragm is likely worn and should be replaced. Enviro replacement diaphragm kits are available for all ET series pumps and cost a fraction of pump replacement. Keep a spare ET30 in your grow room kit for backup in any application where temporary interruption of aeration — such as overnight during a hot UK summer — would risk root zone oxygen depletion in an active growing system.
Use the Enviro ET30 Air Pump with a small quality air stone and 4mm airline for a compact, reliable, quiet aeration solution for any small-scale hydroponics, propagation, or nutrient mixing application.
