Similar hazardous fumes experienced by dental technicians and ceramic artists need the attention of application specialists

Stroll through our inspection and shipping department on any given day and you will be intrigued by the variety of activities that require fume extraction for worker safety.

On this day, two ceramics-related particle-containment applications were notable.

Dental ceramics application


An order for a Model 340 Ductless Containment Hood was being shipped to a dental organization to control particulate created when dental lab technicians used precision tools to shape and refine molded ceramic teeth.

Ceramics studio application

Bulk ingredients being re-packaged.

A community college ceramics department mixes clays and glazes from bulk powder ingredients and did not want staff and students to inhale dust created during the mixing.

The department ordered a Model 300 Portable Fume Extractor with dual flex hoses.

Applications specialists identify appropriate solutions

Let’s lay out some of the details in a table:

Problem Examples of Typical Materials Encountered Work process; task frequency Solution
Dental office: Contain particles created as molded teeth are ground with precision tools







Aluminum oxide
(may cause lung damage)

Zirconium oxide (toxicological properties not fully investigated yet)

Silica (may cause lung diseases, including silicosis and lung cancer)



Technician returns to same work bench, tools every day; works in seated position. May also perform post-processing tasks with pigments and epoxies with odors many find unpleasant.



Model 340 DCH with HEPA to trap particles and carbon to trap odors.
Sentry Air Model 340 Ductless Containment Hood.
Ceramics studio: Dust plumes created when clays and glazes are mixed; plumes can contain particles of toxic materials used in ceramic processes



Cobalt carbonate (suspected cancer agent)

Iron chromate (may lead to the increased susceptibility to lung disease)

Silica (may cause lung diseases, including silicosis and lung cancer)

Studio staff mix clay ingredients and glaze ingredients in different rooms every 2-3 months. Fume extractor can be rolled to where the task is being performed.



Model 300 Floor Sentry Double with HEPA filter to trap particles.

Sentry Air Model 300 Portable Fume Extractor with dual extractor arms.

As you can see, our applications specialists suggested a ductless hood for the dental ceramics application and a portable fume extractor for the ceramics art studio.

Other factors

In their discussions with customers, our specialists want to determine customers’ maintenance practices and budgetary goals.

For example, in the case of very high particulate production that rapidly saturates a filter, our specialists may suggest a unit with cleanable, re-usable filters like the Model 300 RoundaireTM Micro-Pleat.

Chatty applications specialists

In other blogs, we’ve suggested our Sentry Air specialists ask a lot of questions.

That’s what you should expect – prefer – when you seek an engineered air solution to a problem.
