Description
ENVIRO ET100 AIR PUMP is the mid-range Enviro air pump designed for single to dual-site DWC growing, medium propagation systems, and applications where an output between the compact ET80 and the higher-capacity ET120 is the right specification. We have been supplying Enviro air pumps to UK hydroponics growers since 2017 as a dependable, cost-effective range for grow room aeration that balances output, noise, and longevity effectively at every size tier.
ET100 Output and Typical Applications
The Enviro ET100 delivers adequate airflow for one to two medium air stones in reservoirs of 20–60 litres, making it the natural fit for a single Oxypot or standard DWC bucket with a Jellyfish or Starfish stone, or for dual-outlet operation in two smaller propagation units simultaneously via an airline tee. It sits between the ET80 (suited for the smallest single-site applications) and the ET120 (designed for four to six site systems or large single reservoirs), occupying the practical middle ground for growers whose operation has grown beyond a single small unit but who do not yet need the output of the ET120 across their full aeration setup. Like all Enviro pumps, the ET100 is designed for quiet continuous operation in domestic growing environments where pump noise is a consideration.
Setup and Service
Connect to your air stone via 4mm airline and position above the waterline of all reservoirs the pump supplies. The ET100’s dual-outlet design allows simultaneous operation of two air stones without a manifold — each outlet supplies one stone directly. Service the diaphragm annually or when output noticeably declines after cleaning. Enviro ET100 diaphragm kits extend pump service life significantly and are available as a low-cost replacement part.
Pair the Enviro ET100 Air Pump with a Starfish or Jellyfish air stone, 4mm airline, and your preferred DWC nutrient system for a well-oxygenated root zone that drives healthy growth throughout every stage of your growing cycle.
