2. Aerosol Spray Containment Ductless Spray Booth Series “Simple Solutions for Cleaner Air”
Sentry Air Systems Ductless Spray Booths are built with stringent quality control measures and superior craftsmanship.
If your application requires a benchtop hooded enclosure for aerosol spray control, Sentry Air Ductless Spray Hoods may
be an excellent choice. These negative-pressure systems utilize powerful fans and high-quality pre-filters, HEPA filters,
and Activated Carbon filters. This combination helps to protect the operator’s respiratory zone and prevents unwanted
spray particulate and odors from entering the general work area. Sentry Air Systems Portable Spray Booths are
extremely energy efficient and do not require costly external ducting. They are an optimal fume control solution for
environments that do not have to access to or are not permitted to exhaust aerosol particulate and fumes outdoors.
Typical portable spray hood uses may include light spray painting, conformal coating, aerosol sprays, epoxy overspray,
and a variety of other processes that expel aerosol particles and fumes.
FILTERED AIR
STEP :
FOUR THE FINAL [OPTIONAL] STAGE OF FILTRATION IS AN
ACTIVATED CARBON FILTER. THIS FILTER REMOVES VOC’S AND ODORS
REMAINING IN THE AIRSTREAM. THE FILTERED AIR IS RECYCLED BACK
INTO THE ROOM.
STEP :
THREE SPRAY PARTICLES AND AEROSOLS THAT WEREN’T
REMOVED BY THE PRE-FILTER ARE CAPTURED IN THE 2ND FILTER STAGE
– A HEPA [UP TO 99.97% EFFICIENT ON PARTICLES 0.3 MICRONS
AND LARGER] OR ASHRAE FILTER [UP TO 95% EFFICIENT ON
PARTICLES 0.5 MICRONS AND LARGER].
STEP :
TWO THE CONTAMINATED AIR IS CARRIED THROUGH THE
INTERNAL SPRAY PRE-FILTER RACK INSIDE THE HOOD. LARGER
AEROSOL PARTICLES OVERSPRAY PARTICLES ARE CAPTURED HERE.
AND FUME
STEP ONE: OPERATOR PERFORMS APPLICATION WITHIN THE HOOD,
GENERATING OVERSPRAY, WHICH IS PULLED UPWARD BY THE FAN.
