System for suppression of pollution in fiber attenuating operations, especially in mineral fiber insulation blanket production. The system disclosed provides gas blast attenuation of the attenuable material in a fiber forming chamber and for recirculation of attenuating gases and for discharge of a portion of the gases by means of a controllable blower. The operation of the blower is regulated by a pressure sensor responsive to the pressure in the forming section.
