The LF125 "Framed" Soundproof Generator Enclosure
This design has an independent internal frame.
As the name suggests, this enclosure does not need to be fixed to a wall or the floor.
This provides the flexibility of being able to:
1. Remove & replace an entire sides for complete access from any side
2. Move the whole enclosure elsewhere, should this be required at some point in the future.
This video contains footage of our old 2019 model.
The new 2022 model has the same level of sound attenuation
but is more durable and weather resistant.
See images of the new model in the page below the video.
We'll be re-filming the video with our new 2022 model soon.

Features & Benefits
1. Soundproofing
The LF125 Enclosure boasts an impressive 30 dBA drop off at 1m, as measured with a calibrated sound level meter. The sounds drops by a further 20 dBA reduction at 7m.
Please be aware that a 10dBA reduction in noise levels is nowhere near sufficient to solve generator noise problems as you'll still exceed the acceptable noise levels set by municiple by laws by a large margin. If your generator runs at 95dBA which is very common then it's imperative to get a minimum of a 30dBA drop off.
2. Sound Absorption
Sound is absorbed differently at different frequencies. Damping generator noise requires high sound absorption at low frequencies in order to be effective, as low frequencies travel further and are far more difficult to attenuate. We can all relate to the doof, doof, doof noise of the party next door or the taxi driving past a block away.
The LF125 sound absorbers used inside our soundproof enclosure absorb 70% of sound at 125Hz and 100% of sound between 250 - 5000Hz. NRC 1.05
Open cell polyurethane foams are typically very poor sound absorbers at low frequencies which makes them unsuitable for this application.
3. Fire Safety
The LF125 sound absorbers used inside the enclosure are non-combustible.
We often get feedback from clients who have been sold an open cell polyurethane foam and I cannot emphasise enough how risky this is, as it is highly flammable and emits toxic fumes if it burns. Yes, I have spoken to people who have had first hand experience of the kind of disaster this can cause - rather don't do it.
Remember the scouts Moto "Safety first". It's always far better to prevent the problem than have to solve an expensive and dangerous problem afterwards.
4. Easy Access Hatch
We provide hinged doors for ease of access.
5. Detachable Sides
All the sides and the roof are fully detachable and can be easily removed without any tools. Thus you always have all the access you need, from whatever side you need it - for maintenance and refuelling.
6. Airflow
Commercial grade extraction fans are provided with the enclosure, to move air across the generator to prevent it from overheating. The fans must be connected by your electrician so that when the generator starts, the fan also starts automatically. With a fan at each side of the enclosure there is built in redundancy for added safety.
Acoustic Baffles
Airflow is directed through two acoustic baffles: One to draw cool air in and the other to exhaust the hot air out on the opposite side. Thus the temperature is controlled without any compromise to the sound attenuation.
7. Exhaust Ventilation
The exhaust should not be vented into the soundproof enclosure, as over time the dirt in the fumes will coat the generator, the inside of the enclosure and will eventually cause the extraction fan to fail.
Also it would not be safe to open an enclosure and breath in toxic fumes. In order to overcome this problem and safely vent the exhaust outside, we provide a flexible galvanised steel pipe. The pipe is sold separately by the meter.
Available diameters in mm:
25, 32, 38, 50 and 65
A bolt clamp comes with the pipe, in order to fasten it over the exhaust outlet. Wall mounts are also available.
