Updraft & Overhead Capture Systems
1. What is it?
Updraft and Overhead hoods, completely or partially enclose the process or contaminant generation point.

For example:

A Complete Enclosure would be a sealed “box” or similar type of configuration where only minimal openings exist and the contaminated air is sucked up and away. The enclosing hood is preferred wherever the process configuration and operation will permit.

A Partial Enclosure would be an “open box” (i.e.: with the lid cut off). An inward flow of air through the enclosure opening will contain the contaminant within the enclosure and prevent its escape into the outside work environment.
If a complete enclosure is not feasible, the partial enclosure should be used to the maximum extent possible.
3. Will it make my workplace safer?
Yes it will, but only when systems are set up and maintained for the correct application. Filter selection is the most important variable to ensuring the reliability, effectiveness, and safety of the unit you use.
4. Suitable industries & environments

5. Available models and variants
For a list of available models, check out our catalog below.
6. Preventing the spread of airborne fumes & chemicals
Industrial workers are exposed to various health hazards all the time. These workers go to work with the risk of becoming sick, ill, or disabled. According to a WHO estimate (WHO, 2000), unintentional poisonings led to 300 000 deaths in the year 2000.

It's our mission to diminish that figure, but it only works if the correct equipment is used, and configured for the right contaminant. Our team works to make the logistics of those questions as straightforward and coherent as possible, and as such, will work with you to provide you with the best extraction system that fits your worker's needs. From accessibility and usability to reliability and longevity.

HC-4-Flexi - UPDRAFT & OVERHEAD CAPTURE SYSTEMS
hc-4--suspended-filter-system-with-four-flexi-extraction-arm-fumes-dust-gases - 3D Main Image 300
Horizontal cartridge collector with 4 Clean-2® filter cartridges.
Designed to be paired with our Flexi extraction arms. Up to 4 arms can be operated at once.


Our filter cartridge system is an ideal solution for limited floor space, as well as high maneuverability. It has a nominal airflow rate of 2000 CFM
With the use of our Flexi extraction arms, 4 stations can be filtered at any given moment, allowing for maximized productivity.

Comes prepared to accept up to 4 Flexi© Extractor Arms (ordered separately), which allows for excellent extraction right at the source. This solution is ideal when a packaged "Pre-engineered" solution is required. Suitable for most welding and light dust applications.

Options:
  • Pressure Gauge Kit: Indicates when filters require cleaning.
  • Silencer: Reduces noise up to 4 dB.
  • Custom Cartridge Media: For specific applications.
  • 14-ft. E-Z Arm® High Flow Extractors: Replaces standard 10-ft. E-Z Arm® Extractors for peak system performance.
  • (2) 8-in. Dia. Inlets: Simplifies ducted application installation (less dual arms.)

LEV Overhead Hoods - UPDRAFT & OVERHEAD CAPTURE SYSTEMS
local-exhaust-ventilation-lev-overhead-receiving-hoods-welding-grinding-vapours-gases - 3D Main Image 300
LEV-Hoods are pre-engineered ventilation hoods that are available with optional filters and fans. These simple designs are ready to mount in a "free-hanging" manner above welding cells or work tables. They allow the aerosols to be "received" from various industrial processes and further treated or exhausted as required.

Overhead hoods are the perfect option for limited floor space or the desire for a clean and tidy extraction system. Our hoods are quiet and efficient, making them virtually unnoticeable within the workplace.

LEV-Hoods are an excellent solution when at-source capture of pollutants is not possible, practical, or convenient. - a nice quiet efficient and effective contaminant capture system.

Our overhead hood system uses a three-stage filter configuration composed of a 2-inch baffle filter for spark resistance, a 4-inch pleated filter for capturing larger particles, and a final multi-pocket high-efficiency bag filter for capturing the smallest particles.

Through suction, the contaminant is either "received" by the hood or contained by a fabric enclosure where the contaminant can be optionally filtered and or transported to the atmosphere.

Most Systems can be put in position with minimal mechanical installation time, typical 2 hours/2 men per hood. Electrical motor and lighting connections are also required.

Available Options:
  • Silencer
  • Floor Stand
  • Magnahelic Pressure Gauge
  • Manometer
  • 65% Bag Filters
  • Welding Curtain

F91 - Updraft and Overhead Capture Systems
f91-suspended-filter-system-with-extraction-arm-fumes-dust-gases - 3D Main Image 300
The F91 is an overhead self-supporting extraction system that can hold one or two extraction arms with airflow ratings of 1100 CFM to 1300 CFM.

The F91 extraction system offers 2, 3, or 4 stage filtration, and with the use of Ultra-Seal® Filter Mounting, eliminates contaminant bypass of filters.
When paired with our 10' Flexi extraction arm, this system provides source capture, removing contaminants.

Optional gas adsorption is available to remove gases as well as particulate matter. Washable pre-filters, a primary bag filter, and optional HEPA after-filters combine to provide 99.97% filtration efficiency at noise levels as low as 79 dB. The unit includes Class II BI blower direct drive with a 3 HP motor.

Available Options:
  • Pressure Gauge Kit: Indicates when filters require cleaning.
  • Silencer: Reduces noise by 3 dB.
  • 14-ft. E-Z Arm® High Flow Extractor: Replaces standard 10-ft. E-Z Arm® Extractor for peak system performance,as needed
  • Filter Options: Chevron® mist collector, Disposable 4" pre-filter, 99.97% efficiency HEPA after-filter, multi-filter gas adsorption module.
