The Powertec AF weighs Stock No. Description This powerful unit is perfect for the smaller home shop. These filters can be cleaned several times before they need to be replaced.

The good news: Each machine was able to return the air to the control level. Obviously, the larger the shop space, the more time each machine will likely need to clean the air. All the rectangular-box machines have a prefilter and secondary pocket filter. Both are easily accessible for cleaning. Eight of nine tested air-filtration systems have two sets of filters, as shown above. The prefilter, made of spun nylon or pleated fabric, captures larger dust particles 5 microns or larger , and can be cleaned with compressed air or a shop vacuum.

Most prefilters will eventually need to be replaced after cleaning no longer improves their performance. The Powermatic PM, below , has a screen rather than a traditional prefilter. Because replacements for these filters cost 4—5 times more than the prefilters, be sure to keep the prefilter clean or replace it often to preserve the inner filter.

As dust particles build up on the filters, airflow drops off, but filtration improves. We suggest erring on the side of caution and cleaning the prefilter about every 7—10 days of working in the shop.

With a couple of exceptions, you can turn the Jet Air Filtration Filter Size Manual unit on or off, control the fan speed, and even set a timer that turns it off automatically via a panel on the unit, or by remote control. The Grizzly G provides the functions on its remote control only.

The Supermax has a gauge that indicates when the filters become too clogged to clean the air effectively. No other units have this feature. Filter upgrades can save an air Jet Air Filtration Filter Size 200 cleaner Curious to see if an upgraded filter Jet Air Filtration System Filter Size 4g would improve performance on these air cleaners, we tested two units with aftermarket prefilters MERV 7 and high-efficiency pocket filters MERV 15 from American Fabric Filter , americanfabricfilter.

However, the Grizzly G improved vastly from minutes using its original filters to just 33 minutes with the AFF filters. First, the Jet AFS proved best overall with the top airflow, fast filtration, and the largest filters fewer cleanings. But its large size could make it unrealistic in some shops, particularly those with a low ceiling. Our Top Value: the box fan.

It would be a tough call to say which one is the best. Your decision will probably boil down to brand preference or the price. The standard Powertec warranty agreement stipulates a period of 1-year for the warranty and a day money back guarantee.

The Shop Fox is in the same league as the other two cheaper options and is also a robust little machine in a tough steel housing. It has basically the same performance as the other two, albeit from a slightly less powerful 0. The filters work in the same way with a 5-micron outer filter and a 1-micron inner filter.

It has a remote control and has timer settings for 1, 2, or 4 hours. It also has hanging hooks and a carrying handle like the others. Changing or cleaning the filters is just as easy as any of the others and replacement filters are also easy to come by.

It has a 2-year warranty — the same as what you get for the WEN and better than the Powertec 1-year warranty. In a workshop that uses cutting, grinding and sanding equipment, dust in the air is inevitable. This is most common in woodworking shops where large amounts of sawdust and woodchips are released into the air as we work. Shops that deal with stone have a bigger problem because many stone products release minute particles that contain crystalline silicone and the health effects from inhaling silicates is particularly dangerous.

This is also true for contractors who cut masonry and stone on site. The main effects of dust or sawdust in the air is that they cause damage to the respiratory system, resulting from particles collecting in the lungs.

Breathing in any amount of dust over a prolonged period can cause irreparable damage to your lungs. Other health problems can be scratching of the eyes and, in some cases, skin irritation. Most woodworking shops will use dust extraction systems that are connected to the machine — usually dust collection bags attached to a vacuum system. These systems are very effective and remove a lot of the wood-chips and sawdust released by the tools that we use. However, there is always dust that is not collected by a conventional dust extraction system.

Small particles of 5-micron or less become airborne very easily and these particles are the most dangerous — causing the most damage to our lungs. They are too small to see and will go by unnoticed unless they are in large volumes. This causes a fine mist in the air. Because most of the fine dust is not collected by regular dust extraction systems, a secondary air filtration system is of great importance.

Not only are particles in the air a cause of health problems, but they can also have a negative effect when applying finishes and paint to the final product. In the US, indoor air quality regulations are a legal requirement for employers in two states — New Jersey and California. Despite the lack of federal legislation for air quality in the workplace, labor law does state that all workers have the right to a safe and healthy working environment.

By default, this means that if the air in the workplace poses a health risk to your employees, you are in contravention of the law — no matter what the state laws are. This is why any workshop that produces dust needs an air filtration system that is capable of removing dangerous particles from the air. This means that it needs to have the correct filters, normally removing particles of up to 1-micron in size. To give you an idea of what this is, 1 micron is 0. For most shops, a 1-micron filtration system is fine for solid matter particles.

An HEPA filtration system will remove particles of 0. Your workshop air filtration system needs to clean the air in the shop times per hour. This means that the entire volume air in the area needs to pass through the air filtration system at least six times every hour.

An air filtration system uses a fan to draw air through the filters and release it back into the atmosphere as clean air without any harmful particles.

To do this you need to calculate the volume of your shop Length X Width X Height , you then multiply this by the number of times you want the air to be cleaned and divide your final answer by Stock No.
