GR-5000 Series

GR-5000 Series

Certified oil interceptor

For occasional automobile mechanics, such as body workshops, car windows, aesthetics, etc.

The interceptor is made of steel coated with enamel antirust paint, including a flow rate regulator, a 2” blowhole at the entrance and exit, a non-skid cover bolted airthight. A warning signal is built in a PVC case ULC + CSA approved to be fixed to the workshop wall (pre-fabricated at factory) and is connected to the interceptor using a 10 foot teck that is burried underground.

A 115 Volt – 15 Amp outlet is required at the workshop for the warning signal. The oil interceptor must be drained at least once a year.

Note: A sand interceptor is required upstream the oil interceptor, with an appropriate capacity (GR-520 series) and has to be drained more frequently to avoid any overflow. (4.7.6)

Our electronic system includes a certified wall-mounted unit with control of the pre-determined retention oils (not high level). This electrical wall-mounted unit requires a power supply of 115 volts, which is connected by a wire tech on the inside of the interceptor to a waterproof junction box, to which are attached three electrodes, powered by a low voltage supply (2 volts).

After having installed the interceptor in the ground, fill it with water until it reaches the inlet connection and afterwards plug the power cord to an electrical inlet connection with a power supply of 115 volts 15 AMP. Once the electrodes come in contact with water, the green light on the wall-mounted unit will indicate that the system is functional.

The used oils accumulate inside the interceptor from the inlet connection level by floating on the surface of the water, being lighter; they are withheld on the inside by the chimney, which descends towards the bottom at the exit, letting only the water escape. The interceptor reaches its full retention capacity once the oils retained inside have thickened and made their way to the bottom, the probes are immerged in the oil and the independent red light turns on in order to notify the user that the interceptor must be emptied.

While undergoing this operation, you must make sure no water runs down the drainage system. After emptying the layer of oil, add water into the interceptor from the drainage system.

Our electronic oil interceptor does not include a shutoff valve at its output that will prevent crippling the buildings sewage-drainage system; our unit is equipped with a safe storage capacity, which leaves ample time for maintenance in case of need, giving the user a considerable advantage.


All floor drains must pour into a sand interceptor and continue in the oil interceptor. The oil interceptor must be ventilated by two 2” pipes running parallel outside the building in the direction of the rooftop; one of the two pipes must exceed the other by approximately 12”. Inside the building, the pipe for the blowhole can be placed on the 2”, but must absolutely be placed on the 3” on the exterior.

An interceptor is not designed to receive used oil from mechanical workshops where oil is changed. It was developed to deal with effluents with the following characteristics: intermittent or variable flow, water/oil mixture, non-soluble/non-emulsifying.

The units must be placed on a base of compacted crushed stone or sand until they are under the concrete floor, and then be cemented to that floor. Prior to the start of operations in the workshop, the interceptor must be filled with clean water to the inlet connection after every emptying or cleaning of the unit. The interceptor must be cleaned once a year or more if needed. The sand sensor must be drained once the volume approaches the inlet connexions before it pours into the interceptor.
