Evolution Aqua Diaphragms for Airtech 130

If your Airtech 130 has lost output or become noticeably louder, worn diaphragms are often the cause. Evolution Aqua Diaphragms for Airtech 130 allow you to service your pump and return it to proper working performance.

Why replace diaphragms?

• Restores full air output
• Maintains stable oxygen delivery in larger ponds
• Reduces strain on the pump motor
• Genuine parts made for Airtech 130

Diaphragms are service components and naturally wear over time with continuous operation.

Signs replacement is needed

• Reduced airflow from diffusers or bottom drains
• Increased vibration or mechanical noise
• Pump struggling under normal load

Maintaining strong aeration is critical in larger or heavily stocked koi ponds.

Installation notes

• Always unplug the air pump before opening the unit
• Follow manufacturer servicing guidance carefully
• Inspect airline, non-return valves and diffusers for blockages before restarting

Routine maintenance protects your aeration system and keeps dissolved oxygen levels stable.
