The Sweetwater Diffuser is a high
quality ceramic type diffuser that is machined from a solid block of glass
bonded silica. This diffuser requires no air filter because dust and dirt
particles up to 30 microns in size will pass right through.
Here’s a quality air diffuser that offers the best diffuser technology
available. This diffuser has an air resistance of 0.25 psi, which makes
this glass-bonded diffuser compatible with economical low-pressure blowers.
It produces a uniform medium-fine bubble and is very resistant to clogging.
Occasional cleaning is necessary after calcium precipitate or bacteria
builds up. May be cleaned and restored to like-new performance by placing
in an acid bath. Comes with a 2 year guarantee.
Sweetwater diffusers are the best choice for aquaculture, wastewater
and lake aerations because of the round grain pore structure, low resistance
and uniform porosity. Sweetwater designed this diffuser to produce the
smallest bubble possible within the constraints of a reasonable service
life. Most soft water applications will not require cleaning for more than
Introduced in 1978, Sweetwater is the original 2,000 degree F glass
bonded, silica diffuser. Others may look the same, but compare quality
and the two year warranty against other brands.
Offers These Fine Features:
Custom sizes and fittings available
Self-weighting when used with typical tubing lengths
2 Year Warranty
Very Clog Resistant
Minimal Cleaning & Maintenance
(Note: Water pH in excess of 9.0 will shorten the diffuser life)
Note: Length & width dimensions are + 1/8” (3mm). Non-standard
fittings are available. The suggested CFM is typical for aquaculture. Higher
CFM amounts will create larger bubbles. PE is high density linear plyethylene.
ABS is green plastic.
Oxygen Transfer Rates These transfer rates are based on typical aquaculture conditions. Oxygen
transfer rates may vary due to varying testing methods. These rates were
measured in clean water at 20 degrees C (68 degrees F). The tests started
at 1ppm and ended when D.O. reached 6.6 ppm. (The transfer rate is faster
in warmer water.) Remember this general guideline when using this chart:
100 lbs (45kg) of 1/2 lb fish require .04 lbs. (18 gm) of O2 per hour.
