Description
Description
Splitter Silencer
The Elta Splitter Silencer is a baffle type rectangular silencer designed to reduce duct borne noise in higher airflow systems where a circular silencer may not achieve the required attenuation. It is built with a 300mm plenum and supplied with a Ductmate flange connection for a secure fit into rectangular ductwork.
Select models are available for next day delivery.
Why this silencer is specified
- Effective noise reduction: insertion loss data is provided across octave bands to support accurate acoustic selection
- Splitter design: baffles help increase attenuation within a compact footprint
- Built for ductwork: Ductmate flange detail supports straightforward site installation
- Robust construction: galvanised steel casing with perforated steel lining plus baffles
- High quality infill: glass tissue faced high density mineral wool absorbing infill
Construction overview
The unit uses a galvanised steel outer casing with perforated steel lining and internal baffles. The infill material is glass tissue faced high density mineral wool. The design includes a 300mm plenum section as shown in the dimensional drawing.
Sizes and key dimensions
The range covers face size A from 350mm up to 1000mm. Length C varies by size, with 1200mm, 1500mm and 1800mm options shown. Fixing is via a Ductmate flange with four fixing holes, with hole diameter shown as dimension D in the data sheet.
| Product code | A (mm) | B (mm) | C length (mm) | D hole dia (mm) | Ductmate flange (mm) | Weight (kg) |
|---|---|---|---|---|---|---|
| 068-0350-MFB | 350 | 400 | 1200 | 9 | 25 | 24 |
| 068-0500-MFB | 500 | 550 | 1200 | 9 | 25 | 42 |

Full size coverage includes 350, 400, 450, 500, 550, 650, 700, 800 and 1000. Use the datasheet table to confirm the exact dimensions plus weight for your selected size.
How to use the insertion loss data
Insertion loss is shown by octave band. For selection work, use the insertion loss values with your fan sound power data to estimate the combined result across the octave band spectrum.
Selection tip
Match A to your duct requirement first, then confirm the overall B dimension plus the C length to ensure you have enough installation space. Use the listed weight for handling planning and confirm the Ductmate flange size for compatibility with your duct connection detail.
