The ProAir™ 2 is the most advanced diuser on the market today and is specically
designed to maximize circulation and oxygen transfer in ponds and lakes. The
ProAir™ 2’s weighted sled design keeps the diuser 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 diuser also
includes a check valve to prevent back pressure to the compressor.

MAINTENANCE
We recommend inspecting and/or cleaning the membrane diuser sticks every
24-36 months, or anytime there is a reduction in bubbles from the diuser. To clean,
use Airmax® D-Scale Cleaner (#530298) and a soft cloth.
TROUBLESHOOTING
If you have loss of airow to one or more diusers:
• Check to ensure airow 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 diuser manifold.
