Sentry Air Systems Case Study: Isopropyl Alcohol Fume Control

INTRODUCTION Sentry Air Systems, Inc. manufactures equipment designed to capture organic solvent vapors and/or other air contaminants and, after removal, return the cleaned air to the local environment. The equipment consists of an electric motor-driven fan mounted on the top of a ductless hood that draws contaminated air through a filter or canister containing the… Learn More

Sentry Air Systems Case Study: MEK Fume Removal

Methyl Ethyl Ketone Fumes: Methyl Ethyl Ketone, also known as MEK and butanone, is one of the most prevalent ketone compounds and is used in a wide variety of applications. It is primarily produced industrially on a large scale from 2-butanol. MEK is a popular solvent and dissolves many materials. It is frequently used to… Learn More

Sentry Air Systems Case Study: Acetone Fume Removal

Acetone Fumes: Acetone, also known as propanone and dimethyl ketone, is the simplest example of ketone compounds and is also a very important building block in organic chemistry. It is produced and disposed of naturally in the body as a result of normal metabolic processes. The majority of acetone is produced from propylene in a… Learn More

Ductless Fume Hood Case Study: Toluene Vapors

Toluene Fumes: Toluene, also known as methyl benzene, is an aromatic hydrocarbon that occurs naturally at low levels in crude oil and which is also produced as a byproduct in fuel production. Its electrophilic properties make it a useful feedstock in industrial processes such as the production of TNT and polyurethanes. It is also used… Learn More

Ductless Fume Hood Case Study: Xylene Fumes

Xylene Fumes: Xylene is a name given to any one of three aromatic hydrocarbon isomers produced from crude oil. Each of the isomers is similar in its properties. There are many applications in which the use of these xylene isomers is necessary including uses such as a solvent in the leather, rubber, and printing industries…. Learn More
