225 & 330 FINE BUBBLE DISC DIFFUSER
 

 

MATERIAL OF DIFFUSER  

A. High quality EPDM membrane 

B. The membrane must  close quickly when stop air supply.
The selfcleaning design prevents clogging and highly resistant to fouling.The physical characteristic is as follows:
 
Tensile strength          2000 PSI  
Tear strength              110 Lb/linear inch 
Ozone resistance        Pass 
UV resistance              Pass  
Durometer                   60  Ultimate
elongation                   700%
 
C.The disc base and retaining ring  shall be molded high quality ABS( POLYLAC) .  
The physical characteristic is as follows:
 
Specific Gravity                          1.06 
IZOD Impact Strength                2.6 ft-lb/in
Tensile Strength                         7090 PSI
Tensile Elongation                      15﹪
Maximum Temperature               85℃ 

D. Connection to the air header:3/4” NPT threads

Features:
Low operating costs
Reduced energy consumption when we operated the membrane diffuser brings considerable cost savings

Constant back valve
The self-cleaning design prevents clogging and highly resistant to fouling

High oxygen transfer rate
Equally distributed micro pores on the diffuser membrane.Consistently produce 1-3 mm fine air bubbles that increase the surface contact area with water, greatly increasing the oxygen transfer efficiency. 

Simple installation procedures
Diffuser range to be installed on most existing air header systems without special tools required.

Extended lifetime expectancy
EPDM membrane maintains elasticity and is resistant to even the most aggressive wastewater components 

Reliable intermittent aeration operation
An integral check-valve system makes the diffuser ideally suited for air-on/air-off operations such as SBR’s
