Not all oil and gas exploration takes place on a rig

Four wall-mounted Model 400 Fume Extractors, in customer colors, situated over containments hoods sited on a lab bench prevent fumes from spreading throughout the training facility.

Core analysis, a learned skill often taught by energy companies, gathers information used to make oil and gas production more efficient.

No two drilling core samples are alike.

Each contains diverse percentages of water, clay, sand and natural mineral deposits that affect the methods and materials used to remove oil and gas from a drilling site.

In the classroom, core samples are analyzed to determine their porosity and permeability, two characteristics significant to the selection of most effective drilling fluids for the site being worked.

One test important to student-analysts is how core samples and the selected fluids, which in the field are subject to great pressure and high temperatures, will age over time.

To do this, they heat the fluids — which may contain chemicals and polymers — to see if they control alkalinity, degrease oily surfaces, or stabilize a site’s natural flow properties.

Heated fluids produce foul-smelling fumes that shouldn’t be inhaled.

Air filtration for core analysis


To provide respiratory protection for their students, the Baroid arm of Halliburton installed a series of Sentry Air Model 400 ductless fume extractors mounted to a wall over custom containment hoods fabricated in our facility.

Shown in the image at the top of this blog, the fume extractors and hoods prevent hazardous fumes from spreading throughout the training facility.

Facility managers wanted air filtration systems that were both effective and easy to maintain. Filters on the Model 400s are long lasting and easy to replace when saturated.

The containment hoods are sized to accommodate the tools used by the students.

In response to the installation, the classroom lab manager said:

Before installing Sentry Air systems, the fumes from operating high temperature equipment could be overwhelming at times.

After installing the Sentry Air systems, the fumes are contained and the students have added protection against possible fluid splatter.”

Modular design has benefits

Modular design provides benefits in configuration, filtration, and ease of maintenance. Our Model 400s fit exactly into the training center’s existing environment and created a path to the facility’s future.

Because the students’ lab activities produce both chemical fumes and particulate, each Model 400 is equipped with an activated carbon filter and a HEPA filter.

However, if future training requirements require different air filtration, the units can be equipped with one or multiple filter types from our standard catalogue. In addition, re-location of the lab can be accomplished without remodeling ductwork or installing special power outlets.

Made in the USA

Sentry Air Systems produces application-oriented air filtration solutions for varied industries.

Our products are used in very clean environments like pharmaceutical labs and in dirtier environments like metalworking shops.

Our positive-pressure and negative-pressure products offer air filtration protection to both people and products.

Modularity makes customization of their features and benefits readily achievable and cost effective.
