This degasser is rugged, roto-molded using high-density polyethylene and is designed for stacking (note that when stacking units, only one lid is necessary). Removes carbon dioxide (CO2), nitrogen (N2), hydrogen sulfide (H2S) and other volatile gases from the water while adding oxygen.
Setup is simple: Attach the water input lines using flexible couplings. Three 2" water inlets (provided) will handle up to 50 gpm each. Vinyl dryer hose connects the air blower (4" outlet, 3" inlet), which provides required airflow for up to 150 gpm (minimum of 5:1 ratio of air to water). One blower may be used with one degasser at 150 gpm, or with three degassers if the water flowrates are 50 gpm each. Sold with 4 SS mounting eyes.
Each unit requires 4 cubic feet of Bio Barrel media (BF44A). We suggest placing the media in three mesh bags (BF167) to simplify maintenance. An optional, 17" long stainless steel hanger (DGB17) and cables facilitate hanging from above. Overall height of unit is 38". Estimated max weight in operation is 80–90 lbs.
Our DGBlower (not included) is a high-quality, marine-duty unit with a pipe-fitting inlet and outlet (4" hose), that can be mounted virtually anywhere. 115V/60 Hz, 173 watts.
Note: This degasser has been designed for typical clean water aquacultural conditions. When using in unusual cases—systems with high levels of alkalinity, heterotrophic and green water applications, etc.—you may want to oversize the system by adding an appropriate safety factor.
