Ceramic Air Stones

  • Fired at very high temperature (1300C) to create a very strong and long lasting air stone.
  • Uniform size pores produce even airflow and superior oxygenation.
  • Does not corrode or dissolve like sand air stones.
  • Structurally  sound and impact resistant.
  • Requires less air pressure for proper operation.
  • Can be used in freshwater or salt water.
  • Reusable with proper maintenance.
Flat Type High Pressure Ceramic Air Stone (DY 101)


Advantage of backflow prevent (Check Valve): It prevents this air stone from inflow of the water when you stop use it.  There is no damaged due to freeze and burst when you use it again.  And you don't need to increase the pressure to let the water out in the stone.


  • The fisheries culture :
    For high density fish farm. For conveyance of live fish by transportation facilities (truck, ferry, plane etc). For temporary live fish depository.
  • Waste water treatment :
    Oxygen injection for reduction BOD and COD in the river, large and small ponds.
  • Pond
Product Feature:
  • Excellent gas transfer (Oxygen or Carbon Dioxide)
  • Fine bubble size: between 100 to 400 microns
  • High pressure operating range:  22 PSI (1.5 Kg / cm2)  -  36.7 PSI (2.5 kg / cm2)
  • Slime design
  • Strong point of the plastic flame.  
  • No Rust
  • This is already equipped with Check Valve
  • Oxygen consumption is low and fusion rate is high because of an air bubble that these products produce is minute between 100 to 400 microns. (typically more than 40% over recommended operating range and  1 meter depth)
  • The flat design minimizes rising air bubble coalescence.
  • Installing the backflow preventer to prevent countercurrent. 
  • As made from nonpoisonous materials in a particular method of construction, it is safe for aquaculture use.
  • The slim design does not hinder netting of fish and minimizes injury.
  • As the thin profile can be fastened down and far from surface, oxygen fusion rate is high
  • It is a ceramic type made of special material at 1300C
  • Porous, no corrosion and no abrasion
Instruction on its use: 
  • Before you use, immerse the air stone deeply in the water twice or three time for a short time, connect to the air hose, set it horizontally and then slowly set the proper pressure to the desired level.  There will be a small delay before the air stone responds to flow adjustments.  Please wait for a while until it works.
  • Do not increase the pressure when the jetting volume decrease due to impurities on the air stone.  Dry it and scrub the surface with the rough brush, scrubber or sandpaper (#60) till the grime is removed.
  • If there is not regular air  jetting from air stones despite of an above method, please clean with chemicals
  • Please layer two tissues and put them on the ceramic part of the air stone.  Wet the tissues with chlorine bleach for home use and let it be in this condition for 5 - 10 minutes.  Remove the tissues and clean the air stone with fresh water.  You can use it.
  • It can be used longer with good efficiency if you clean the surface of the air stone regularly.
  • Clean it thoroughly it you don't use it for a long time (You must remove salt with fresh water after you use it in the sea water).  Please dry it up and keep it the shade.
  • Avoid physical impact and shock
  • When it use again after keeping for a long time and / or the hose is filled with the water, please check and clean the backflow preventer as the hole may be clogged with sludge of the existing tube.
The flow rate per operating pressure measured only ceramic stone part and when adjust valve (needle valve or flow meter) to control flow, the input pressure of gauge should add 1.0 kg/cm2 to the jetting volume of air stone.  That is because the valve controls the jetting volume while the pressure diminishes.  Do not use this air stones over 4.0 kg/cm2

*** 1kg / cm2 = 14.7 PSI,  1.5 kg / cm2 = 22 PSI,  2.0 kg / cm2 = 29.4 PSI,  2.5 kg / cm2 = 36.75 PSI
