Animated diagram for Single or Dual Work-Station Filter Units
Single or Dual Work-Station Filter Units
1. What is it?
Our single or dual work-stations filter units are standalone or suspended systems with integrated blower and filtration. These units are designed for air recirculation as opposed to standard fume extraction, allowing for a more efficient air purification solution.

Available in several different designs:
  • Ceiling mounted
  • Wall mounted
  • Standalone
  • Portable/maneuverable
2. Suitable applications?
Single or Dual Work-Station Filter Units such as these are ideal for 'Cell Based' manufacturing and work stations. Most of these solutions are based upon self-cleaning filter cleaning systems to reduce filter costs. Water-based systems are also available for certain explosive and flammable applications

Here is a list of applicable processes:
3. Will it make my workspace safer?
ANSWER: Yes, but only when systems are configured, installed, and maintained for the correct use application. The filter selection is paramount to ensuring the reliability, effectiveness, and safety of the unit you use. Lev-co uses three procedures to determine the design and installation of our filter units. These three procedures are OSHA HOC (hierarchy of controls), MOC (management of change), and PSR (pre-start safety review) Lev-co recommends that these three procedures, when appropriate, should be used when selecting filter units.

Here are links to examples of these three procedures:
OSHA Hierarchy of controls
MOC Management of change sample document
PSR Pre-start Health and Safety review
4. Suitable industries/environments?
Work-station filter units serve a wide range of industrial applications. Some applications include metal shops, auto shops, manufacturing facilities, and electrical repair facilities.

Refer to our Industries page for a full list.
5. Available models and variants?
For a full selection, check out our catalog below
6. What criteria to consider
See below:
  • Capacity (How much flow will the filter unit handle?)
  • Capture velocity (can the filters accommodate the required capture velocity to capture the aerosol?)
  • Extraction arm (do you require point source filtration?) (Optional)
  • Can the filters withstand the Pressure/abrasion/corrosion/etc?
  • What is the Total Flow Rate? (How many CFM's are needed to capture the contaminants)
  • What is the exact resistance (filter and capture device losses) required for the fan to overcome?
  • Do I have enough filter media in the collector?(Air to cloth ratio)
  • Will it stand up to your environment (Eg: is it made from Plastic or Steel?)
  • Filter cleaning: Does the filter cleaning system really work in your application?
  • What will be my filter, maintenance and energy costs per year?
  • Are there any tertiary risks such as fire, explosion, etc, that I need to consider?
7. Pros & Cons versus other engineering control methods?
Pro's:

Ideal for cell-based manufacturing.
Easy to relocate work stations and associated filtration equipment
Not reliant on pre-existing ductwork
Energy savings associated with on-demand process-only filtration
Available self-cleaning, or cleanable filters
Available with extraction arms for point source filtration
Straight forward installation and deployment
Long-term cost-saving

Con's:

Multiple systems to maintain
Expensive in short term
Fixed system. Cannot be moved while in use
Limited airflow depending on filter selection
8. Preventing the spread of airborne fumes and chemicals
Industrial workers are exposed to a variety of health hazards every day. As a result, these workers risk the possibility of becoming sick, ill, and disabled for life. 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 correctly. 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.

You can read more about the risks and preventions of fume extraction below:

OSHA
WHO
9. Effectiveness versus dilution ventilation
The integral flaw with dilution ventilation is the contaminants picked up by the system are not ultimately removed from the air. As a result, dilution ventilation is ineffective against most contaminants produced in industrial processes, such as metal fumes, abrasive dust, vapors, gases, and toxic chemicals. Local exhaust ventilation eliminates these issues through the capture of contaminants near or at the source of the contaminant, not allowing the contaminant to enter the atmosphere.

To read up more about the benefits of local exhaust ventilation versus dilution ventilation, refer to these links:
CCOHS
Use of local exhaust and dilution ventilation
10. Maintenance costs
Filtration:
Filter maintenance is paramount to the healthy operation of both your workers and the fume extraction system. We offer a wide range of filter options for multiple applications. Some of these filters are washable, and as a result, reduce maintenance costs to close to zero. However, depending on shop service hours and specific contaminants, filter replacement may be required.
Construction:
All our filter units are built with steel and are welded together for the best consistent performance, and the least leakage. As such, there is virtually nothing about the construction and function of the system that needs maintaining.
11. Do's and Don'ts
Do's:
  • Maintenance checks periodically

Don'ts:
  • Don't leave the unit running while not in use
  • Don't obstruct the airflow
  • Don't change contaminant extraction without referring to either the owners manual, or a Lev-Co representative
12. Installation tips and tricks
For fixed units, options of either wall or floor mounted configurations available. Units can also be retrofitted to pre-existing industrial equipment.
Portable plug & play unit also available for versatile extraction.

Wall Flex-Self Cleaning (WF-SC) - Single/Dual Work-Station Filter Unit
wall-flex-self-cleaning-filter-unit-for-fine-dust-and-fumes - Main Image
WF-SC - A Single/Dual Work-Station Filter Unit that includes a manual Jet-PULSE® filter system. With a max flow rate of 1400 CFM

Once the contaminant is captured and filtered by the cartridge, it is easily 'reverse-pulsed' off the filter with compressed air. This allows for cost-effective filter maintenance and ensures constant capture at the source.

Access to the "maintenance-free" replaceable cartridge filter is easy, and changing it takes just a couple of minutes.

Available with:
  • Filter Options
  • Fan / Motor Upgrades or Options
  • Silencer Option
  • Preventative Maintenance Pressure Gauges
  • VFD Option
  • Adapters
