Flat Type Ceramic High Pressure Air Stone(DY101) 

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

• Immerse the air diffuser in the water for a short time and connect it to the air hose.  Then set it horizontally into the water.  Set the pressure to the desired level slowly

• When the diffusing volume is reduced due to foreign material (Ex: organic sludge, debris and deposit etc) air diffuser takes out from the water and be it dry.  Then scrape the surface of ceramic diffuser smoothly with a sand paper (# 60) until the foreign materials ahs been removed. 

• When you do not use air diffuser for a long time, withdraw it from the water and be it dry.  Then keep it in a dry place.
