Large Cylinder Airstone

Product Information

Key Features

  • Large 300 mm x 50 mm cylinder airstone for high air volumes from a single diffuser
  • Medium pore structure gives consistent bubble size and steady oxygen transfer
  • Low-pressure design, so it runs on economical regenerative blowers rather than high-pressure air
  • 8 mm barb connection for a secure, tool-free hook-up to standard airline
  • Economical option where a large duty has to be covered without a bank of small stones
  • Suited to ponds, aquaria, holding tanks and general aquatic aeration
  • Rated at 20 LPM of air per stone — divide your total blower air flow by 20 LPM to work out how many stones you need (operating pressure is not stated by the supplier, so confirm the duty against your blower curve)

Frequently Asked Questions

How many airstones do I need?
Divide your total blower air flow by the 20 LPM each stone passes — a 200 LPM blower, for example, will run about 10 stones.
What air flow does one stone pass?
20 LPM per stone.
What size airline does it take?
It has an 8 mm barb, so standard 8 mm airline pushes straight on.
Do I need a high-pressure blower?
No — it is a low-pressure design intended for economical regenerative blowers rather than high-pressure air.
What bubble size does it produce?
A medium pore structure giving consistent medium bubbles suited to general aeration duties.
How big is the stone?
300 mm long by 50 mm diameter.
Where is it typically used?
Ponds, aquaria, holding tanks and other aquatic environments where a large air volume is needed from one diffuser.
