Laser fumes produced during laser applications can be harmful if inhaled, exposing operators to health risks like respiratory illness. Fumes contain particulate matter and gases that vary depending on the target material but may include carcinogens. Proper ventilation and extraction equipment are needed to filter fumes and reduce levels below established safety limits. Sentry Air Systems offers various laser fume extraction units suited for different applications, including mounted, portable, and multi-exhaust models incorporating HEPA and other specialized filters.

1. Laser Fume
Health Hazards
and some ventilation and fume extraction options.
Presented by Sentry Air Systems, Inc.

2. Particulate and gas released during laser
applications are harmful to both the operator
and the laser system itself. The inhalation of
laser fumes can lead to long-term medical
conditions and can cause expensive medical
claims for employers.

3. Depending on the target material, applying a
laser beam may produce harmful, respirable
fumes containing:
Polycyclic aromatic hydrocarbons
Hydrogen cyanide and benzene
Heavy metals
Formaldehyde and synthetic fibers
Health effects vary depending
on the chemicals involved and
range from acute irritation to
long-term asthma or nervous
system damage.

4. PROTECT YOUR LUNGS
Here is an excerpt from OSHA’s Technical Manual regarding
Laser Fumes [Section 3: Chapter 6, Subsection 2]
Industrial Hygiene. Potential hazards associated with compressed
gases, cryogenic materials, toxic and carcinogenic materials and noise
should be considered. Adequate ventilation shall be installed to reduce
noxious or potentially hazardous fumes and vapors, produced by laser
welding, cutting and other target interactions, to levels below the
appropriate threshold limit values, e.g., American Conference of
Governmental Industrial Hygienists (ACGIH) threshold limit values
(TLV's) or Occupational Safety and Health Administration's (OSHA)
permissible exposure limits (PEL's).

5. We offer laser fume extraction
units for particulate and gas
filtration, depending on the
application, including:
Laser cutting
Laser welding
Laser marking
Laser engraving
…and more!
Source-capture fume
extraction equipment captures
fumes at the source of emission, before they
are able to escape into the general working
environment.
With multiple filter options and
filter stacking available, there is a
filter media for almost every laser
application!
HEPA
ULPA
Carbon
Gas
Ammonia
Our comprehensive line of laser
fume extractors includes a variety of
configurations including:
Single Exhaust Port
Portable Units
Multi-Exhaust Ports
Custom Configurations

6. Exhaust Port Configuration
Model 200 Mounted Sentry [Model # SS-200-MS]
The Model 200 Mounted Sentry fume extractor is a small but powerful
industrial air cleaner that can be mounted directly to a workbench, a hood,
or even to enclosed machinery. This modular unit provides multiple
mounting options, two inlet configurations [3” or 4” diameter], and can be a
simple and effective addition for multiple brands and types of enclosed
machinery that require fume extraction.
Air Volume: Up to 100 CFM
Filtration Media: HEPA; ASHRAE; Activated Carbon; Specialty Blended
Base Unit Dimensions: 10.5” L x 10” W x 12.5” H
Electrical: 115/1/60, 0.3 amps; 220/1/50, 0.2 amps
Additional Models
SS-300-MS
up to 350 CFM
SS-400-MS
SS-450-MS
up to 700 CFM
up to 950 CFM

7. Portable Configuration
Model 200 Floor Sentry [Model # SS-200-FS]
The Model 200 Floor Sentry is a lightweight and portable fume extractor
that is engineered with a self-supportive flex arm for easy maneuvering
and optimum source capture placement. This unit can be placed on the
floor to free up much needed work space, or it can sit on the benchtop; the
Floor Sentry’s small footprint takes up minimal workspace. The lightweight
flex arm is designed to be placed right next to the source of fumes or
particulate to capture them before they are able to escape into the working
environment.
Air Volume: Up to 100 CFM
Filtration Media: HEPA; ASHRAE; ULPA; Activated Carbon; Specialty
Blended
Base Unit Dimensions: 10.5” L x 8” W x 10.5” H
Electrical: 115/1/60, 0.3 amps; 220/1/50, 0.2 amps
Additional Models
SS-300-FS
up to 350 CFM
SS-400-FS
SS-450-FS
up to 700 CFM
up to 950 CFM

8. Multi-Port Exhaust Configuration
Model 300 Floor Sentry Double [Model # SS-300-FSD]
The Model 300 Floor Sentry Double is designed to provide portable fume extraction to two operators
simultaneously. Two flame-retardant, self-supportive flex arms provide equal suction at both inlets,
which directs contaminants into the patented filtration system. This unit features heavy-duty casters
for easy mobility and an infinitely-adjustable variable speed controller. Endcaps to plug inlet holes are
available when use of only one arm is desired. Other optional features include a digital hour counter
and quick change pre-filter.
Air Volume: Up to 175 CFM High; Down to 50 CFM Low (per arm) [Variable Speed Control standard
on 115V; On/Off Toggle Switch standard on 220V]
Filtration Media: HEPA; ASHRAE; ULPA; Activated Carbon; Specialty Blended
Base Unit Dimensions: 15.5” L x 13” W x 16.5” H
Electrical: 115/1/60, 2 amps; 220/1/50, 0.75 amps
Additional Models
SS-400-FSD
