PRODUCT CONTENTS

The ProAir 2 is the most advanced diffuser on the market today and is specifically designed to maximize circulation and oxygen transfer in ponds and lakes. The ProAir 2’s weighted sled design keeps the diffuser submerged and prevents it from sinking into the muck. The exclusive PTFE non-stick membrane sticks provide the synergy of air stones while being virtually maintenance- free. Each diffuser also includes a check valve to prevent back pressure to the compressor.

MAINTENANCE

We recommend inspecting and/or cleaning the membrane diffuser sticks every 24-36 months, or anytime there is a reduction in bubbles from the diffuser. To clean, use Airmax D-Scale Cleaner (#530298) and a soft cloth.

TROUBLESHOOTING

If you have a loss of airflow to one or more diffusers:
• Check to ensure airflow valves on compressor manifolds are adjusted correctly.

If large boiling bubbles are present on the water’s surface:
• Check membrane sticks for tears.
• Check for loose connections on diffuser manifold.
