This line of systems has raised the performance standard to new heights. Superior performance and reliability are the words that best define it.
The B & F AIR FLOAT removable air diffuser system is suitable for tanks or aeration ponds. The system features floating air distributors, made of high density polyethylene (HDPE). From these floating branches, the diffusion units (aeration grids) are derived, which may or may not be supported on the bottom.
The system is supplied with double feed stainless steel aeration grids through high temperature hoses, ensuring low mechanical stress, excellent mixing and homogenous dissolved oxygen.
The air diffusers used are thin or thick bubble tubular, high efficiency and performance tubing. The number and size of diffusers are variable according to project characteristics.
The great advantage of removable aeration systems is the possibility of implantation or maintenance without the need to empty the tank or pond and its supply and sizing adaptability employed in each project. It also presents the possibility of creating anoxic zones for nitrification and denitrification processes.
The AIR FLOAT B & F series has the same characteristics as the air diffused technology: high efficiency, low energy consumption, reliability and great operational flexibility.

Blowers
B&F Dias has a complete line of air generation systems with centrifugal blowers, bolts and roots developed especially for application in diffusion air aeration systems under the strictest controls and quality standards achieved in more than 25 years of application development. The use of air generating systems with bolts or roots blowers is synonymous with lower energy consumption, guaranteed generation of air free of oil, minimal maintenance and high durability. With a huge variety of models of different sizes, assembled in various configurations, the air blowers stand out for the application of diverse forms of operation with flow intervals from 35 up to 15800 m3 / h with pressures up to 1200 mbar (12 mca). All sets have special accessories for application in diffuse air aeration systems. Bases and couplings, mufflers, air filters, anti-vibration supports, pressure gauges, check valves, safety valves and acoustic insulation cabins.
Interconnection Tubing
B&F Dias is also a company specialized in the design and execution of interconnection piping between the blower house to the point of application (tank / pond / reactor / valve / channel) of the diffusion air aeration system. The dimensioning of this set is made considering the most important factors (air velocity, temperature, load losses) for the application in aeration systems in conjunction with air blowers. With diameters from ¾ “up to 60”, the B & F Dias interconnection pipes are all made with AISI 304 or 316 stainless steel connections and pipes. All correct and suitable fastening, anchoring and guide brackets are also included. (support), control and locking valves.
