About Us

QSI arrestors are the easiest, quickest, safest lowest cost installation in Australia, backed by an ISO9001 quality assurance program, 24 years manufacturing experience and 60 years engineering experience.

QSI deliver free into store to over 83% of the population, saving hundreds, if not thousands of dollars in transport costs. Please refer to our Freight Made Easy Map.

With most installs below the hazardous construction depth of 1500mm, the QSI arrestors are the safest to install and will save you money with less excavation, backfill and tipping fees.

QSI products are the only one with a 10 year warranty.


Whatever the design, the operating principle for an arrestor is for time & gravity to allow fat, oil, grease (FOG) & suspended matter to float to the top or settle out to the bottom (generically called sludge) and be retained in the grease arrestor till pumped out.
