Sereco - Model DRAF 100 -Coarse Bubble Air Diffuser
It consists of a polypropylene diffuser body and a neoprene anti-backflow membrane with elastic sealing able to prevent the water entering the diffuser body. A 1⁄2 inch gas thread connection allows the joining to the air supply ramps. The air, arriving from the supply ramp, goes against the neoprene diaphragm and its flow is then deviated downwards. In correspondence of the annular end, the body shows a multiplicity of holes allowing the air to come out with bubble of coarse size. The geometry and the elasticity of the neoprene membrane allows a uniform air distribution on all the holes and, at the same time, the lateral tightness against the water entering the diffuser.
The DRAF 100 diffuser, thanks to the very low head loss, allows to obtain a high and continuous output in the oxygen transfer. Moreover, due to the special strength of the materials of which is made, ensures very low investment and maintenance costs. For its characteristics, the DRAF 100 diffuser has become essential in the pre-aeration, aeration, mixing, stripping, degreasing, oil separation and sand removing processes. The DRAF 100 type, mainly designed for the oxidation and homogenizing processes, is used in the aeration and internal recycling where a coarse bubble air ratio is needed; in particular conditions can be used also for carpet aeration.
