Commercial grease traps in Australia: Sapphire and sizing basics
A commercial grease trap (grease interceptor or grease arrestor) captures fats, oils and grease from kitchen wastewater before sewer discharge. Most Australian food premises need an approved arrestor under trade waste rules.
GRAF grease range in Australia
GRAF Australia supplies under-sink grease traps, Grease Buster (above ground), Sapphire Grease Trap and Grease Arrestor SC. Selection depends on kitchen size, peak flow, install location and authority rules.
Domestic under-sink traps are usually too small for busy cafes and restaurants. Undersized traps fail audits and create odour and overflow issues.
What to send for sizing
Share fixture schedules, peak covers and any published authority sizing rule. Size from peak flow and fixture counts, not floor area alone. Design must leave safe access for pump-out and cleaning.
Quote through grafaustralia.com.au or 1300 131 971. Searching only for grease trap cleaning finds service contractors, not new hardware for a fit-out.
