Hydro-Mechanical Grease Interceptor .
A plumbing appurtenance that is installed in the sanitary drainage system to intercept free-floating (FOG) fats, oils and grease from the wastewater discharge.
Continuous separation is accomplished by air entrainment, buoyancy and interior baffles .
Gravity Grease Interceptor.
A plumbing appurtenance of not less than 500 gallon capacity that is installed in the sanitary drainage system to intercept free-floating (FOG) fats, oils and grease from the wastewater discharge.
Separation is accomplished by gravity during a retention time of not less than 30 minutes .

ADD on GREASE SENSORS
grease separator alarm For applications with greater amounts of solid grease than normal.
In alarm condition it will energize the internal buzzer and LED. For remote indication of the alarm condition the relay output facility can be utilized.
