These characteristics have been met through the unique technology used to produce the Pearlcomb® diffuser. The diffuser tube is made up of minute resin spheres which have been fused together under pressure. This construction provides a highly uniform, porous material which lends itself for use as an excellent diffuser media.  

The Pearlcomb® diffuser may be mounted on any header manifold having 3/4” threaded bosses. Installation is convenient since the diffuser is lightweight and nonabrasive. Pearlcomb diffusers are available in either simplex or duplex configurations.

By selecting the proper control orifice, optimization of system head loss against oxygenation transfer efficiency can be effected, thereby minimizing system cost.
