Maezawa Kasei Industries Grease Trap Main body made of FRP, GTA-NP, pipe inflow, buried type ■ Model → GTA-N22 + Iron Lid 　Allowable inflow rate: 22.5 (l/min) 　Diameter: 75 (mm) 　Total weight: 16 (kg) 　Pressure resistance: T-0 (pedestrian load) (Old model number: GTA-30-N) I bought this recently and haven't used it once. It doesn't quite fit, so I'm putting it up for sale! I took it out of the box, so there might be a little dust, but don't worry, it's completely unused.
