GGLX R
The GGLX-R is a straight sound attenuator with mineral wool filling. The sound absorber consists of a perforated sheet steel tube enclosed by end pieces and a sheet steel casing. The space between the tube and casing is filled with attenuating material covered with non-woven fabric as protection against fibre migration.
This product can be used without any maintenance other than cleaning, which should be done with a nylon brush as part of normal duct cleaning. The frequency of cleaning should be the same as that specified for the entire ventilation system.
