Ductless Hood for Spray & Paint
40" Ductless Spray Hood
Model # SS-340-DSH
The 40” Wide Ductless Spray Booth provides a negative-pressure hooded enclosure for the control of aerosol spray. These energy-efficient systems utilize powerful fans and a variety of high-quality filtration media to provide effective source-capture of airborne contaminants. A unique internal spray filter, HEPA filtration, and Activated Carbon media help to protect the operator’s respiratory zone while also preventing unwanted spray particulate and odors from the entering the general work area. The ductless and recirculating design of this benchtop hood eliminates the need for external ducting or costly replacement air.
Ductless Spray Hoods are typically used for light spray painting, aerosol sprays, epoxy overspray, touch-up painting, conformal coating fumes, and a variety of other processes that release aerosol particulate and odor.
In addition to our Standard Portable Spray Booths, we offer Custom Spray Booths built for those customers with specific application requirements.

Meets OSHA Requirements: 1910.107(b)(5)(i)
Standard 1910.107(b) is the OSHA standard for spray booths under the main standard “Spray finishing using flammable and combustible materials.” A spray booth is defined in this section as ”a power-ventilated structure provided to enclose or accommodate a spraying operation to confine and limit the escape of spray, vapor, and residue, and to safely conduct or direct them to an exhaust system.” As a manufacturer of spray booths Sentry Air seeks to comply with and abide all national regulations and standards. As no such regulations exist for ductless spray systems, Sentry Air products conform to those standards that could apply to ductless systems and exhausted systems alike, such as standard 1910.107(b)(5)i.

I purchased my Sentry Air Systems spray hood to control the fumes and particulates when spray painting custom radio controlled aircraft canopies. I use heavy duty automotive paint and solvents and the hood significantly reduces the odors and air borne particles. It is quiet and efficient and my clients can watch me in action in my paint studio thanks to this great air filtration system!"

�It works exactly as advertised and has been a tremendous asset to our productivity. Assembly was simple with the CD and the fit and finish is very nice. When we needed to make a couple of modifications to meet our needs, the staff at Sentry was helpful and timely in making it happen. I highly recommend Sentry Air Systems and their products"
