Hydromechanical Grease Traps separate Fat, Oil and Grease (FOG) from greasy water which typically results from the preparation and service of food.  The term Hydromechanical Grease Trap means a design that incorporates air entrainment, hydromechanical separation, interior baffling, or barriers in combination or separately.

In the past concrete was commonly used in the manufacture of grease traps but the presence of acids in greasy waste resulted in corrosion and breakdown of the unit within as little as 10 years.

MACTRAP manufactures grease traps from High Density Polyethylene (HDPE) which remains totally unaffected by greasy water acidity allowing us to provide a 30 year warranty with all inground units – a strong financial motivation for building owners.

The benefits of MACTRAP grease traps start at installation. Because they are lightweight and easy to transport and maneuver they require less machinery and time to install saving up to 50% of upfront costs. If your application requires a custom size or configuration we can typically design and build to meet those requirements within four weeks.

MACTRAP manufactures products to support New Zealand’s environmental goals and all of our products comply with the NZBC G13.
