Year-round pond aeration with the Blue Diamond Enviro ET80

The Blue Diamond Enviro ET80 Septic or Pond Linear Diaphragm Air Pump delivers a steady, oil-free stream of air to ponds, water features, and septic systems. By infusing water with oxygen, the device supports clearer water and healthier aquatic life without relying on additives. In freezing conditions, the ET80 also acts as a deicer, helping to reduce surface ice buildup while you enjoy outdoor spaces longer.

What you get with the ET80

• All aluminum air pump chassis built for durability
• UL, TUV, and CE approved for safety and reliability
• Used by original equipment manufacturers of NSF certified residential sewage treatment systems
• 75 liter per minute air flow, suitable for many residential septic setups

Key performance figures include up to 2.83 cubic feet of air per minute, a maximum pressure of 0.10 bar, and a modest 75-watt power draw. The unit ships with a 0.71 inch OD connector and a 1/2 inch ID bronze fitting for straightforward piping connections.

Durability you can rely on

Designed for outdoor use, the ET80 features weatherproof housing and a robust diaphragm. When service is needed, replaceable diaphragm kits help extend the pump’s life, while the quiet operation helps it blend into pondside spaces without dominate noise.

Easy installation and routine maintenance
