What type of situation would call for the use of an Extract-All® brand Portable Fume Extraction (Air Cleaning) System?
Answer: In an application that requires a high level of filtration, but for various reasons, the application is located in an area without adequate ventilation, the use of a Portable Fume Extraction System will remove harmful airborne contaminants from the workers breathing zone, and from entering the room environment. Portable Fume Extractors are not connected to an exhaust system. They utilize filters to contain vapors, fumes and dusts, before air is recirculated back into the room. Our Portable Air Cleaning and Fume Extraction Systems can provide a practical solution for lab and industrial environments where a ducted system is not feasible. Because of their portability, they may be moved from location to location and stored away when not in use.
Many of your systems seem similar in size, and specifications. How do I determine which system I need?
Answer: Most of our systems are specifically designed for compact spaces and work areas. Your choice of system depends on your particular set-up. Each system offers the same high level of filtration. Choose the system that best fits your application. Our systems have different configurations – some of our systems use self-supporting extractor arms, while others use downdraft or backdraft intakes. Each application is unique and may require one approach over another.
What distinguishes your Extract-All™ brand from competitive brands?
Answer: In today’s environmentally conscious society, there are many different options available to those wishing to purchase an air cleaning system. It is sometimes difficult to sort through the various claims made by manufacturers. Often times prices are drastically different for products that, on the surface seem similar. However, there are several main advantages the Extract-All® brand offer:
- Heavy-duty construction.
- Long life blower motors.
- User-friendly design makes maintenance and filter changing fast and simple. Most competitive brands require tools just to change filters.
- Accurate specifications. We do not make false CFM and Filter claims. Many competitors inflate the numbers.
How do I determine if I need a Primary Particulate Filter or a Primary Vapor Removal Module?
Answer: Choose the Primary Vapor Removal Modules for chemical fumes, gases, odors, or vapors. Choose a Primary Particulate Filter for applications with fine particulates such as dust, smoke or mist. For applications that have both visible particulate and gaseous vapors, we offer multi-stage filter set-ups. Choose a combo filter package that consists of either a HEPA or 95% particulate filter, with a vapor after-filter.
What type of Filter Media is used in the Vapor Removal Modules?
Answer: Our Vapor Removal Modules are available with a variety of activated carbons, impregnated carbons and chemically modified Zeolites. Our special V-Bank design prevents bypass. These filter medias adsorb chemical fumes, including organic solvents, ammonia, acids and formaldehyde.
How often should the filter media be replaced?
Answer: This is by far the most common question we receive. Every application is different. There are many variables that effect filter life. The type of material being collected, the concentration levels, process temperature, ambient temperature, humidity level, etc. all have an effect on filter life.
How can I determine when to change the filter media?
Answer: Our Extract-All® Portable Air Cleaning Systems come with a particulate Prefilter. A Prefilter is necessary because it prolongs the life of the Primary Particulate filter. The Prefilter and ParticulateFfilter do not lose efficiency over time. However, they can clog up and reduce the airflow, thus making them less effective over time. When you notice a decrease in performance, first replace the Prefilter. Continue to replace the Prefilter until that no longer brings the performance up to an acceptable level.
When changing the Prefilter no longer brings the performance back to an acceptable level, it is time to change the Primary Particulate Filter.
The adsorbent media in the Primary Vapor Removal Modules and Vapor Removal Afterfilters should be changed when noticing odor. For very light chemical vapor and intermittent applications, the activated carbon could last 6-12 months. For heavier chemical vapor removal applications, we recommend the filter media be replaced every 3-4 months. If you would like a more specific recommendation, please provide details of your specific application to one of our application specialists.
How should I dispose of the used filter media?
Answer: That depends on the composition of the captured contaminants. Please follow your local and state regulations.
What is the motor life expectancy for your Extract-All™ brand Air Cleaning Systems?
Answer: Most of our blower motors are totally enclosed and thermally protected. Blowers are also dynamically balanced. Typical motor life is 100,000 hours, depending on operating conditions, including ambient temperature, duty cycle, etc.
I see 'Room Air Cleaners' advertised everywhere. Are they as effective as your 'Source Capture' systems?
Answer: Capturing vapors and solids directly at the source is the only proven method for effectively removing the highest percentage of airborne contaminants. If you place an air cleaner in the corner of your room, you would need a “jet engine” to pull the heavy fumes and solids over to it. An ambient system (“Room Air Cleaner”) will only filter what gets to it.
With that said, a room air cleaner can be effective as a supplemental system to a source capture system. An ambient system can also be used in areas where a source capture system is not practical.
Can I purchase replacement filters from a hardware store or other after-market source?
Answer: While you could find after-market filters that will fit into our systems, we highly recommend that you use the filter media the systems were designed with.
Our research and development team spends countless hours evaluating different filter media to determine the best quality, efficiency, and fit for our systems. Also, the use of after-market filters will void the warranty on your system.
