Grease Muncher GM700 Grease Arrestor

The Global Water Grease Muncher GM700 combines a conventional underflow grease arrestor design with a special bio-filter to dramatically reduce the grease content of the discharge through microbiological activity.

Key benefits of the Grease Muncher include:

  • constructed with polyethylene and thermoplastics makes it easy to install as well as corrosion and odour proof
  • UV stabilised for safe above-ground use 
  • durable enough to be encased in concrete for below ground projects
  • compact gas-tight design allows for installation in-store and plant rooms
  • pumping chamber available where gravity drainage is not possible
  • maximised efficiency by solids and grease reduction up to 90%, BOD reductions by 45% and a biological filter that removes solids down to 2 mm



The DrainAce Compact is commonly found in restaurants, basements of high-rise buildings, boardrooms, laboratories, doctor or dental surgeries, construction sites and portable buildings. Units are also available for greasy waste discharge from grease arrestors. 


The GM700 is suitable for the following applications: 

  • cafes and bars
  • small restaurants
  • canteens
  • club kitchens
  • fast food restaurants 

Periodic cleaning by a liquid waste contractor to remove build up will be required.




The Grease Muncher has undergone extensive field trials in Australia and is suitable for flow rates up to 1000 L/hr.

Manufactured from a combination of polyethylene and thermal plastics for long life, durability and maximum corrosion resistance. The polyethylene chamber greatly simplifies the cleaning process and reduces smells as fats and grease will not adhere to polyethylene.

Suitable for either below ground or above ground installation, Global Water’s GM700 is a light-weight construction, making it ideal for tenancies where retrofitting or relocation may be required. 

The Grease Muncher is compliant with SA Water standards for Grease Arrestors, and successfully achieves a 1000 L/hr flow rate. Tests have shown a reduction in grease and total suspended solids of 50-90% and BOD reduction of up to 45%.

At Global Water, we specialise in reliable, high quality treatment systems. Our solution for treating greasy fluids is our grease arrestor, the Grease Muncher. This system separates the grease from the fluid and can transfer the treated product at 1,000 litres per hour.

Exceptional features

The Grease Muncher’s intelligent design makes it compact and lightweight, making it easy to install in tight places and relocate. The tough polyethylene chamber provides impact and UV resistance that allows for above and below ground use.

This grease arrestor also provides maximised efficiency by reducing biological oxygen demand (BOD) and filtering solids as small as two millimetres.


The Grease Muncher gas-tight design allows it to be stored in any location of a facility where it is suited to transfer discharge from sinks and dishwashers to sewer lines. It is a popular solution for handling greasy fluids in cafes, bars and fast food restaurants. It’s particularly useful wherever conventional grease arrestors are unusable due to space restrictions.
