Blue Diamond ETA Series Air Pumps with Alarm offer versatility for enthusiasts who manage ponds, aquariums, and even specific septic applications. The Blue Diamond ETA Series Air Pumps with Alarm are typically used in the septic industry but can also work for aquariums or ponds. The built-in alarm has a switch with three settings. Use "test" to check if the alarm is working before installing. After installation, choose "alarm" for both flashing light and sound, or "mute" for just a flashing light, based on your preference. If the airline pressure gets too low, either the buzzer and / or LED lights turns on to alert there is an issue happening. This early alert helps you catch potential problems before they turn into bigger, more expensive issues like sewage backups or overflowing drain fields.
These pumps are designed to withstand various weather conditions, featuring a robust and compact build with the main body constructed from cast aluminum alloy that are great for pond owners who love taking care of their ponds. Energy-efficient Green Drive Technology saves on electricity. Use them for jobs that need a little air or ones that need it all the time. If you ever need to fix them, changing the diaphragm is simple. Exclusively developed diaphragm material makes it last a long time. Manufacturer recommends replacing diaphragms ever 18 months for optimal performance, which Blue Diamond provides one new set of replacement diaphragms in each new unit.
Connections: The air outlet features internal threading for use with the provided barb adapter, but for 3/8" tubing, we advise using the supplied rubber elbow instead. If you're using larger tubing, you can connect it directly to the smooth outer surface of the air outlet. The 14mm outlet can support 1/2" tubing, while the 18mm outlet can handle 5/8" or 3/4" tubing. If you intend to use 1/2" tubing with the 18mm outlet, you will require additional adapters.
