The firm, which supplies the property clean-up and garden machinery market, said the new Quietvac from Billy Goat had noise levels as low as 97 LWa and 77dBa at full power.
Pinnacle Managing Director Ian Lobb said: "The kit is good for parks, streets, pedestrian areas and other public places, is unobtrusive, and has minimum impact on the local community.
"Low noise emissions aren’t the only trick. Cyclonic filtration with dust sock reduces debris, another environmental benefit. The six-blade armour-plated steel fan can reduce material by a factor of 12:1 when composting."
Lobb said the manufacturer had also focused on ease of use. A two-latch bag system made unloading and loading more straightforward while turf-tyres and front coasters offered "smooth fingertip-controlled manoeuvrability".
"Quietvac options include reverse speeds up to 3mph, an on-board hose kit for easy reach in difficult-to-access places and parking brakes," said Lobb, based in Ascot, Berkshire, and the main UK distributer for Billy Goat.
