The Barrel assembly is attached to the Arm assembly. The Barrel assembly also allows for the motor beater assembly to be attached easily to the top for ease of service and maintenance.

The Barrel assembly has an attachment at the top that allows for the extraction of the separated gasses from the drilling fluid (mud).

This design allows for the efficient extraction of drilling mud gasses and control of the sample collection chamber. This is an improvement over other extractors that act much as a centrifugal pump and spit drilling mud from the side. The long vertical tubing also acts as a condensation tower that helps eliminate much of the water vapor in the extracted sample.

The Cavitator also has a small diameter vent hole attached to the extraction chamber that allows for atmospheric pressure equalization.

This vent can be shielded from wind or blocked off completely for a difference in sample gasses extracted.

A simple and inexpensive rubber cap blocks the upper condensation tube opening. The upper tubing is fitted with a brass nipple where the sample extraction tubing is attached.

Clean up is easily facilitated by just removing the rubber cap and rinsing with pressurized water.

Rock cuttings do not pose an occlusion problem in the extraction tube because if any buildup accumulates above a certain point in the tubing it will just slide back down into the main chamber due to gravity. Sample extraction is enhanced by the Cavitator improved main chamber design. This also helps eliminate sample dilution.

The smaller design has also allowed this extraction system to attach directly to smaller shakers.

The motor beater assembly is a lightweight, high power motor assembly that is attached through a steel cap that attaches to the Barrel assembly. The shaft of any of the motors is attached to a balanced stainless steel custom fork assembly that is tested and can spin at over 4000 rpm.

The Motor beater assemblies come in 4 types depending on the setting and environment of the user.

1. The Air motor beater assembly or;
2. The 12-24 VDC motor beater assembly or;
3. The 12-24 VDC explosion proof motor beater assembly or;
4. The 120-240 VAC motor beater assembly.

Each type of motor type has its advantages.

The Air driven motor beater assembly can typically be driven with 10-50 PSI of air depending on the type of drilling fluid it is used in. It is protected from over pressure with a 60PSI pop off valve at the air motor assembly. This motor assembly is ATEX Certified as well as Class 1, Division 1 xplosion proof. It is classified as an oil-less motor, however, we also sell a water trap / in-line oiler and pressure regulator to go with it.

The Water trap has a built in water dump so that if water does collect in the line and trap, it will automatically be dumped when the float level inside reaches about an inch. Also, the regulator portion will keep the pressure nominal while the post oiler can maintain a mist of oil to the air motor beater assembly.

The 12-24 VDC custom MagMotor explosion proof motor beater assembly is good for extreme environments that need an explosion proof rated DC motor. This motor assembly is the smallest and most powerful low voltage ATEX Certified Class 1, Division 1 explosion proof motor in the world. With the proven reliabilty of MagMotor and an extended perioid of operation in extreme and severe environments, we are sure you will be satisfied with this new design of Cavitator Motor Beater assembly. The design is based on rare earth magnets for extremely high efficiency as well as low current, low voltage and low temperature design for extreme rugged environments.

Includes explosion proof conduit box. The 120/240 volt AC motor assembly is utilized for more general installations at the shaker where low voltage solutions are not available. This motor assembly is ATEX Certified as well as Class 1, Division 1 explosion proof and built by the Marathon Motor Corporation.

The Cavitator brand mud gas extractor has been used worldwide by companies which include Baker Hughes, Horizon, Columbine, as well as numerous others.
