A fume extractor<\/strong> is a system utilizing a fan to pull fumes and particulate into a filtration system cleaning the air of harmful chemicals and particulates. Industrial processes create fumes or particles such as welding, sanding, grinding, spraying, powder filling, and chemical applications. Fume extractors use a variety of filters while some systems, depending upon application, use multiple filters in line. The combination of the powerful fan and high-quality filtration media creates a recirculating air pattern for ductless units. Because of the air flow, ductwork or costly replacement air is not required. These units take up less space, weigh less, are more energy efficient, and have easy access to change filters. <\/p>\n

Particulate Filters<\/strong><\/h3>\n

\"HEPA<\/p>\n

Particulate filters utilize high efficiency fiberglass media to arrest and intercept particles, light dust, smoke and other airborne particulate. This type of filter is used to prevent asthma, allergies causes, and prevent disease spread.<\/p>\n

MERV Rating:<\/strong><\/em> 17-20<\/p>\n

Uses:<\/em><\/strong> Particulate control, light dust collection, bacteria laden air reduction, other respirable particulate and dust control. <\/p>\n

Types:<\/em><\/strong> Differs on efficiency. See chart below for overlap of HEPA and ULPA filters and sample particulates captured by both. <\/p>\n

\u2022 ASHRAE Filter<\/em> (Up to 95% efficiency on particles 0.5 microns in size) \u2013 lowest quality that meets standards set by American Society of Heating, Refrigerating, and Air Conditioning Experts. Not as efficient as HEPA but used for similar purposes.
\n\u2022 HEPA Filter<\/em> (Up to 99.97% efficiency on particles 0.3 microns in size) \u2013 high filtration levels to catch small particulate to prevent asthma and allergies.
\n\u2022 ULPA Filter<\/em> (99.9995% efficient on particles 0.12 microns in size) \u2013 ultra low particulate filter has better filtration than HEPA catching more particles smaller in size than HEPA. <\/p>\n

\"HEPA<\/p>\n

\n

Activated Carbon\/Specialty-Blended Filters<\/strong><\/h3>\n

\"Activated
\nFor activated carbon and specialty-blended filters,<\/strong> the efficiency depends on the chemical being adsorbed and the application. These types of filters are used to adsorb organic vapors and solvents. Activated carbon has millions of pores that create a large surface space to adsorb odor and chemical fumes. These types of filters do become saturated and must be replaced to optimize efficiency. Sentry Air Systems uses organic virgin coconut shell activated carbon which is the highest quality available. <\/p>\n

Uses:<\/em><\/strong> To adsorb chemical fumes, organic vapors, and solvents (i.e. acetone and formaldehyde). For more information about activated carbon chemical adsorption rates please view our chart<\/a>. <\/p>\n

Efficiency:<\/em><\/strong> Depends on chemical and application usually 99% <\/p>\n

Types:<\/em><\/strong>
\n\u2022 Activated Carbon
\n\u2022 Carbon Acid Gas
\n\u2022 Aldehyde Carbon
\n\u2022 Ammonia Carbon
\n\u2022 Mercury Carbon<\/p>\n

\n

Micro-Pleat\/Cleanable Filters<\/strong><\/h3>\n

\"Micro-Pleat
\nMicro-Pleat or Cleanable filters<\/strong> can be cleaned by applying pressurized air to the exterior of the filter. These filters are easy to clean because they do not need to be removed while cleaning. The waste from the cleaning process will fall into the internal dustpan for easy removal. These types of filters are best utilized for high volume applications where filters become easily saturated. <\/p>\n

Uses:<\/em><\/strong> High volume welding, metal working, solvents, powder handling and chemicals<\/p>\n

Efficiency:<\/em><\/strong> 95% on particles down to 0.3 microns

 <\/p>\n

Why you should use a fume extractor?<\/h2>\n

Fume extractors are necessary to meet the P<\/strong>ermissible E<\/strong>xposure L<\/strong>imits (PELs) set by OSHA<\/strong> (Occupational Safety and Health Administration). Adhering to PELs is required by law and if found otherwise by a surprise inspection from OSHA, the organization will possibly get a citation with a deadline to fix the issue or be subject to pay fines. If OSHA conducts an inspection due to a workplace accident, immediate fines will apply to violations.<\/p>\n

Not only to follow the law, fume extractors can help organizations avoid legal issues, improve employees’ health and safety, and increase employee morale. Expensive law suits from chemical exposure could bankrupt a company or substantially damage it. Employers should care about the employees’ health and safety to maintain a productive workforce. Employees\u2019 satisfaction and morale will improve because they know that their employer cares about their safety and health.<\/p>\n

Sample Chemical Limits<\/strong><\/h3>\n

For the PELs of specific chemicals, please refer to the OSHA Annotated Table Z-1<\/a>. For information about the NIOSH (National Institute for Occupational Safety and Health) Recommended Exposure Limits(RELs) please visit their website for the NIOSH Pocket Guide to Chemical Hazards<\/a>.
