Grease trap odour control systems
Grease trap odour control with the Garbage Doctor® neutralises the strong, pungent smell of a grease trap or grease arrestor at the source, 24/7, with a fragrance around the trap if you'd like one.
Grease traps often give off a strong, pungent smell, in restaurants, food courts and hotel kitchens, and they differ greatly in size and design. So the system we recommend depends on the type of grease trap or grease arrestor you have, whether the trap is above or below ground, and the space around the trap.

How the Garbage Doctor® is installed
Our technicians mount the Garbage Doctor on a wall as close as possible to the trap, and pipe the ozone evenly into the area around the trap or, on some sites, into the grease trap itself. The aim is to neutralise the grease odour as close as possible to the source, before the odour can spread. Where the odour is a problem, we can also release a fragrance into the wider area outside the targeted ozone, which helps a great deal.
Grease traps can be quite site specific, so we recommend sending us photos or a video of yours first for the best guidance. For advice and a quote, free of obligation, call 1300-ODOURS (1300 636 877). Our technicians work throughout Sydney, Melbourne, Brisbane, the Gold Coast, the Sunshine Coast, Airlie Beach, Tweed and Auckland.

Stainless steel, mounted on the wall as close as possible to the grease trap. Inside, UV lamps turn a small amount of the air's oxygen into ozone. The main unit also holds the scenting controls, which are connected to the scent tank.
Grey PVC conduit runs along the wall above the grease trap, with small holes to release the ozone just above the trap, the same way as over garbage bins. Targeting the ozone at the source neutralises the grease odour before the odour can spread.
A grease trap, or grease arrestor, holds back the fats, oils and grease from a kitchen's waste water: the grease floats on the water and the solids settle on the bottom. The grease trap's strong, pungent smell escapes around the lids, where the ozone above the trap meets the smell.
Mounted on the wall by the door, away from the trap, and connected to the main unit by a small blue hose. The tank holds your choice of fragrance.
The scent tank sends a scented vapour out of a short pipe on top, into the wider area outside the targeted ozone, which helps a great deal where the odour is a problem.
