The B&F AIR GRID removable diffuser air system is applied to tanks or aeration ponds of all types. The system stands out for offering high density of diffusers, allowing the injection of high air flow.
The feeding of the grids is made by flexible hose connected to the interconnection pipe coming from the blowers.
The system comes with aeration grids that are supported on the bottom and are made of stainless steel with tubular diffusers of the fine or coarse bubble type, high performance. The quantity and size of the diffusers are studied for each project.
Like the AIR FLOAT system, the great advantage is that the system is installed or maintained without the need to empty the tank or pond and its adaptability of delivery and sizing.
The AIR GRID B&F series is unique in the market and 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.
