AER Powered Bench or APB Downdraft Tables

April 11, 2016

The AER APB downdraft table is a very popular unit, it is a self-contained cartridge filter dust collector with its own blower, all mounted under the downdraft table.  The APB comes in several size table tops, 42”x 50” (APB4250), 42” x76” (APB4276), and 48” x 102” (APB48102).  Each size table has either two,  four, or six cartridge filters going from small to large.  Each model has two choices for a very strong motor blower per model depending on the application. The downdraft table velocity is easily 250 feet per minute or higher depending on the tabletop size.  The very high velocity is important for drawing the dust down into the table.  The APB comes standard with a manual push button air pulse cartridge filter cleaning system, dust drawers under the cartridge filters, a filter pressure drop gauge and a manual motor starter make the APB unit a drop in place ready to go.  The APB is very adaptable, the filter cabinets and blower cAPB6076-Front-view-with-2000-lb-Lazy-Susan-modified-crop-300x217abinet under the table are modular which means that if you want the blower to discharge out one side or the other you can, although the standard is to discharge out of the back.  AER has built these tables with a larger tabletop overhang than standard, which is 6”, we have gone to 12”.  Sitting on the tabletop is a back and side hinged side shield (nice feature for longer parts), but sometimes we are asked to remove the back and hinged sides for what we call a flat top.  Flat tops are beneficial if your operator wants to walk around the table to work on the part.  AER has also added an enclosure that sits on the table top to enclose the part and contain the dust while it is being worked on.  The enclosure could also have a backdraft which draws the dust to the rear of the enclosure.  If your process generates spark we can include a spark arrester, or water and sand pans to protect the filters.  The standard cartridge filters are flame retardant 80/20 blend; if you need more efficient filters we have our NANO fiber available.  If your process needs an extra back up filter to protect against Hexavalent Chromium Fume or silica for example we can offer a HEPA after filter.  If you want to roll around the APB we can add casters for portability.  One of the very special designs that AER did was to mount a lazy susan to hold a 2000 lb part in the center of the table.

Vertical Small Cartridge Filter (VSCF-800) Dust Collector

April 11, 2016

VSCF-800-Hopper-Casters-HEPA-144x300Have you ever wished that someone made a small self-cleaning cartridge dust collector?  AER Control Systems manufactures a nominal 800 CFM cartridge dust collector with either a 1 or 1.5 HP blower or a 4” or 6” inlet.  This unit provides a more efficient dust collector than our Dust Cab 800 shaker bag dust collector.  The VSCF-800 is a very compact unit, the footprint is only 25.5” wide by 24” deep, and the overall height with the motor is about 4 feet tall.  The standard unit has a 125 square foot cartridge filter, a dust drawer, manual push button air pulse filter cleaning, and a mini-helic filter pressure drop gauge to indicate when to change the filter.  This unit started out to be a simple dust collector, but our sales force has created many options for this small unit including casters, hopper and stand, HEPA After filter, and an on-demand filter cleaning system called our Smart Pulse.  The photo below includes just about every option mentioned above all wrapped into one unit, starting on the bottom you have casters mounted to a base plate where the legs and hopper are attached which support the VSCF-800 that has the Smart Pulse cleaning and a HEPA after filter mounted on the top of the unit.

Are you in compliance with OSHA’s Crystalline Silica Standard? (Pt. 1)

April 11, 2016

1. What is Crystalline Silica (Quartz)  and in what materials is it commonly found in

Crystalline Silica (Quartz) is a component of sand, stone, rock, concrete, brick, block, and mortar.

2. Who is exposed to Crystalline Silica?

Anyone who works with the above materials is exposed.  Operations such as cutting, sawing, drilling, and crushing these materials would be at risk for silica exposure or silicosis.  Workers also involved in sand products such as glass manufacturing, foundries, and sand blasting.  Anyone who works with ceramics and stone in stone shops is exposed to silicosis.  Manufacturing of soaps and detergents is also a source for silica exposure.  More than 100,000 workers are exposed and are at high risk in the USA.

3. What is Silicosis?

Silicosis is a disease of the lungs due to the breathing of dust containing crystalline silica particles.  This dust can cause fibrosis or scar tissue formations in the lungs that reduce the lung’s ability to work to extract oxygen from the air.  There is no cure for this disease; prevention of the dust exposure is the only answer.  According to the Secretary of Labor more than 250 people die from Silicosis in the United States per year.  We have to work towards the exposure to silica by providing dust collectors that protects the worker’s breathing zone.

4.  What are the symptoms?

The most common is chronic silicosis which develops for years undetected and doesn’t show up until 15 to 20 years of exposure.  After many years if you have one or more of the following; shortness of breath, severe cough, fatigue, loss of appetite, chest pains, and fever after working with the above materials for many years.  If you have these symptoms, then please go see a Doctor and get an X-ray of your lungs.

5.  What can workers and employers do to prevent silicosis?

This is where AER Control Systems can help; AER Control Systems manufactures dust collectors with a HEPA filter as a final filter on all of their products.  Think of the HEPA filter as a safety or back up filter to the filter before it so you not only do you get one very efficient filter but two and the second one is a HEPA filter providing 99.97% efficiency at 0.3 microns.  Using a HEPA filter on the unit will guarantee that nobody will be exposed to silica in the shop once the dust is captured in the dust collector.  You will still have to effectively capture the silica dust at its souce.  This is accomplished by making sure you have the correct size unit for the application, please contact AER Control Systems with questions?  866-265-2372.

AER Control Systems Portable Fume Booth

April 11, 2016

front-of-fume-booth-187x300Do you ever have the need to spray a small part with a paint spray can, blow off a part having solvents on it, and perhaps brush on a resin or glue that has a strong odor?  These are just some of the applications where the Portable Fume Booth is perfect for the job to get rid of the nasty odors that are associated with all of the above issues.  The Portable Fume Booth consists of a heavy duty table top with a back and hinged sides, a light above the table helps to visualize what you are working on.  The fumes and odor are drawn down into the table at 150 feet per minute air velocity, which is a very strong suction strength.  The first filter is a pre-filter called a polyester ring panel, a multilayer, multi dense polyester batting type material that removes any sticky, wet, large dust material protecting the MERV 14 (95% ASHRAE) filter above.  Whatever gets by the throwaway polyester ring panel ends up in the throwaway MERV 14 filter and is stopped.  The only particles going through this filter are the odors, which are then removed by the two 28 lb refillable activated carbon cells. There is a total of 56 lbs of carbon in the unit.  The final filter is another polyester ring panel, which is designed to stop any fine dust from the activated carbon that is being broken down into dust.  Above the filters is a very strong single phase 1 HP TEFC motor that is driving a non-sparking blower providing the suction power.  On the blower discharge are silencer stacks that prevent the discharge air from ever seeing the motor. The silencer stacks are used to keep the TEFC out of the airstream, just in case any of the discharge air is flammable.  The Portable Fume Booth comes standard with wheels, and casters for immovability, an on/off switch with power cord, and Magnehelic gauge to determine when the filters need to be changed.  When you receive this unit from AER Control Systems simply plug in the cord, turn on the switch, and away you go.

Understanding & Controlling Hexavalent Chromium

April 11, 2016

SONY DSCDid you know that breathing hexavalent chromium is very hazardous? It can cause lung  cancer and damage to the respiratory tract if high amounts are inhaled.  OSHA has an allowable limit based on an 8 hour average of 5 milligrams per cubic meter. NIOSH has an even stricter limit of 0.2 milligrams per cubic meter.  A basic understanding of milligrams per cubic meter is how many particles are in a volume of air space measured in cubic meters.  Hexavalent chromium (CrVI) is produced several different ways in manufacturing. The largest producer of hexavalent chromium is in the welding of stainless steel or chrome painted parts, according to the Federal Registry, it is estimated that 269,379 workers are exposed to Hexavalent Chromium due to welding.  The second largest is painting using a chrome-based paint, which accounts for an estimate of 82,253 workers exposed.  Electroplating is third with an estimate of 66,859 workers.  If you are looking for reference material regarding Hexavalent Chromium, you can search on the Internet; both OSHA and NIOSH have excellent documents regarding regulations.

What are some control measures to reduce the exposure to hexavalent chromium? One measure is to limit the workers exposure to hexavalent chromium and make sure an individual worker doesn’t exceed 5 milligrams per cubic meter during an 8 hour span of time.  A simpler and easier control method is to use one of AER Control Systems fume or dust collectors.  If your manufacturing process is the welding of stainless steel and you need a portable weld fume collector then one of your choices are the Small Portable Collector or SPC unit. If you are looking for more of a central system using ductwork then our Vertical Cartridge Collector or VCF series is a great choice.  If you have limited floor space and you want a ceiling mounted dust collector then our Horizontal Cartridge Collector or HCF-3000 series is the collector for you.  On all of these cartridge collectors, the cartridge filter is 99% efficient at 0.5 microns, more than efficient enough to stop the hexavalent chromium. Even so, AER Control Systems strongly recommends using a HEPA after filter, which has the efficiency of 99.97% at 0.3 micron to absolutely guarantee that you will not be blowing any hexavalent chromium throughout your shop.  The HEPA simply acts as a secondary or backup filter to the cleanable cartridge filter.

Understanding MERV Filter ratings in the AER Control Systems’ Units

July 11, 2013

People in the Air Filtration Industry can understand when you say a filter is 30%, 95%, or 99.97% efficient, but cannot understand as well if you say the filter has a MERV 7, MERV 14, or MERV 17 rating which would correspond to the aforementioned efficiency levels. AER Control Systems manufactures many different types of units that filter dust, mist, fume, and smoke.  The AER Control Systems filters are set up so that the less efficient filter is first in the dirty airstream followed by a series of more efficient filters.  The number and type of different efficient filters depends on how large and small the particles are in the airstream.  See below some of the common filters that AER Control System uses with references to the old understanding of efficiency in percentage and the filter MERV rating.
