GTG Silencers comprises both Circular Silencers and Rectangular Silencers.
GTG Circular Silencer comprise of CS (without pod) and CSP (with Pod) models. These are used to control the sound passage along an air path. The silencers are tested in accordance with ISO 7235 - "Measurement Procedures for Ducted Silencers".
Both models are made of GI Sheet cased with high density acoustic infill material (glass or mineral fibre) protected by perforated GI Sheet. Model CSP comes with a spun head to minimise entrance and pressure loss. All models comes with flanged ends for direct coupling to axial fans or ductwork.
Standard range is available from size 315 to 1600mm. Each size is available in 1D or 2D as standard length. 1D = 1 times inside fan diamater and 2D = 2 times inside fan diameter. Non standard sizes/length requirements can be supplied upon request
- Powder coated housing
- Mounting bracket for silencer
GTG Rectangular Silencers are rigidly constructed and consist of a galvanised sheet metal casing containing a series of centre and side splitters.
There are 3 different silencer type, i.e. Type S, Type M and Type H. All have different splitter and airway widths and consequently different percentage open areas The casing is provided with Pittsburgh corner seams.Splitter infill material is glass or mineral fibre faced with perforated galvanised steel to protect the infill from erosion. Acoustic infill is suitably faced to prevent erosion of the fibre at passage velocities up to 50m/s.
Standard lengths available in 900, 1200, 1500, 2400 and 3000mm.
