ABSORPTION SILENCERS WITH 200 and 100 mm BAFFLES OVERVIEW TECHNICAL CHARACTERISTICS OVERVIEW: The rectangular shaped SA series of silencers are basic elements for air-conditioning plants, as they allow the noise generated in air ducting to be reduced. They can be used for air or smoke intake or expulsion systems, ventilation for soundproofed cabins, cooling circuits for generator sets, and in airconditioning and ventilation systems. ABSORPTION SILENCERS: These are used for all applications in which mean and high sound frequencies are between 500 Hz and 8000 Hz. ABSORPTION SILENCERS AND RESONANCE: These are used in all special applications where mean and low sound frequencies are between 120 Hz and 1000 Hz. CHARACTERISTICS: Silencer - outer frame: Made of galvanised steel sheet. Silencer - fixing: By tightening bolts or nuts to connect the silencer's flange to that on the ducting. Baffles - holding frame: In galvanised steel sheet. Absorption and resonance baffles - holding sheet: The height of the baffle (H) is broken down into two equal sections and for the entire depth (P) the lower part is covered by a solid sheet. The upper part may be covered by a micro-expanded sheet. Baffles - material used: Jacket made of high density mineral fibre, covered externally by a protective glass film. Baffles - reaction to fire: Not inflammable - class 0. SPECIAL SILENCERS: SAR Model with baffles enclosed in micro-expanded steel sheet. SARF model as the SAR but with baffles enclosed in micro-expanded steel sheet and water-repellent fibre form. SR model absorption and resonance silencer SRR model as per SR but with baffles enclosed by micro-expanded steel sheet. SRRF MODEL as per SR but with baffles enclosed by micro-expanded steel sheet and water repellent fiber form. SL model External frame and baffle holding frame made of raw aluminium sheet. SLR model as per SL but with baffles enclosed by micro-expanded steel sheet. SLRF model as per SL but with baffles enclosed by micro-expanded steel sheet and water-repellent fibre form. SI model Outer frame and baffle holding frame made of stainless steel sheet. SIR model as per SI but with baffles enclosed by micro-expanded steel sheet. SIRF model as per SI but with baffles enclosed by micro-expanded steel sheet and water-repellent fibre form.
