IAS offers a complete range of economical air and oxygen injected devices to suit the needs of the project. Venturi injectors are very effective single point injection devices with no compressed air or oxygen required. Aeration discs and tube diffusers provide effective diffusion of air with low pressure losses and medium sized bubbles typically used in moving bed biofilters (MBBR) and tank aeration. For finer pore in-tank diffusion, we offer silica air stones and fine pore diffusers. Call IAS for free assistance with selecting the right air diffuser for your application.
