About FiltrationTypes of FiltrationTypes of Filters Filtration is an enormous issue when it comes to industrial vacuum cleaners. After all, if you take the time to vacuum an area, the last thing you want is the same material that you just vacuumed to be exhausted right back into the airstream. Depending on what you're collecting, the dust or debris may be hazardous to your product, or even your health. We, at Nilfisk Industrial Vacuums, realize the importance of ultra-efficient filtration systems and put our guarantee on every industrial vacuum cleaner we manufacture.Small particles in the air, on the floor, and on your machinery can be dangerous for a number of reasons. Most importantly, they can contaminate your product and endanger your workers' health. Nilfisk industrial vacuum cleaners can filter down to 0.12 microns in size. One micron is equal to one-millionth of a meter, or 1/26,000 of an inch. On average, the human eye cannot see particles that are smaller than 50 to 60 microns.

Particles that are 10 microns or less are considered respirable and can settle deep into the lungs – often causing adverse health effects. Respirable particles make up greater than 99% of the 7 million particles in every breath you take.To give you a better idea of just how small a micron is, consider this: the diameter of a human hair is 80 to 100 microns in size.If (A) is the diameter of a human hair (100 microns), then (B) is the size of the smallest particle visible to the human eye (50 microns), and (C) is the size of a 0.5 micron particle.Nilfisk industrial vacuum cleaners features filtration systems that are capable of filtering down to 0.12 microns!Now that you have an idea of the types of dust and debris our vacuum cleaners are capable of removing, we should explain how a filter works. For particle filtration, the airborne particles that have been vacuumed must come in contact with the filter media. There are five basic mechanisms by which this can happen: straining or screening, impaction, interception, diffusion, and electrostatic enhancement.

Straining, also know as screening, occurs when the spaces between the fibers of the filter media are smaller than the particles, therefore they are captured.Impaction takes place when larger particles with adequate momentum are unable to follow the airstream around the fibers of the filter media and therefore collide into it and are captured.Interception occurs when particles are small enough to follow the airstream, yet come within a half-particle diameter of the fiber. The particle is captured by the fiber by means of molecular surface attraction.Diffusion, or the Brownian movement, takes place when small particles that don't have sufficient momentum because of their low mass are bombarded by air molecules, interrupting the particles' pathway, therefore causing them to move about randomly. The irregular path of the particle increases the likelihood of being captured by the fibers of the filter. The smaller the particle, the stronger this effect.Electrostatic Enhancement occurs when fibers have a permanent electrostatic charge.

Since particles are attracted to the opposite charge, they gravitate toward the filter fibers, allowing the fibers to capture the particles.To ensure that your vacuum cleaner meets the dust control requirements for your specific cleaning application, Nilfisk, Inc. offers a complete line of filters. Each filter is designed to optimize the performance of your Nilfisk vacuum cleaner. They are ideal for the control of food ingredients, grains, ultra-fine pharmaceutical powders, powder paint, lead, asbestos, silica, pesticides, and other nuisance and hazardous dusts and debris. sanyo vacuum cleaner canisterFor critical environments, our filters meet cleanroom standards up to and including ISO 4 (Class 10) standards.hoover vacuum cleaner forumNilfisk filters meet or exceed all standards for filtration efficiency. vacuum cleaner wands and hoses

With its bright colors and small stature, it might be easy to mistake the Dyson Small Ball vacuum for a child’s toy. But no, the company says the compact machine is simply meant for smaller homes. It’s not the company’s first foray into a small vacuum, and the Small Ball has updates to several features from the very similar Dyson Ball Compact Animal. For $400, Dyson says you get an easy-to-store cleaner that handles both hardwood and carpeted flooring. Here’s what I found when I tested it out. The Small Ball is 32 inches tall, with its handle collapsed. It has a familiar Dyson style, especially with the rest of the Ball models, though this one sports a gray-and-bronzish-yellow color scheme. The canister is clear, giving you an all-too-transparent view of how gross your floors are. The vacuum has two wheels in the back and a cleaner head with a nylon-bristle roller in front. Its bin has a capacity of 0.21 gallons, and it comes with two attachments: a combination tool with a brush on the end and a stair tool with velour strips for picking up hair.

The vacuum’s handle raises and retracts, based on whether you’re using it or storing it. It lifts when you pull it, but you have to press a large red button to get it to lower again. It clicks into place at only one height, about 10 inches tall — a size that seemed to work equally well for my 5-foot-3-inch mother and 6-foot-2-inch father when they gave it a spin. The hose tucks away into a compartment within the handle. To use the hose with the attachments, you have to completely unwind all 31 feet of the cord to get to it, which is annoying if you’re just spot cleaning with an attachment tool. The same button on the handle unlocks the hose, so you can slide the handle backwards and pull it out. You can either pull the handle all the way out of the hose and click the attachments into place on the hose, or flip the handle upside down, open the cap at the top, and use the wand as an extender. There are two protrusions on either side of the vacuum for holding the attachments when you’re not using them.

At just over 12 pounds, the Dyson seemed a bit heavy for something so small. There’s a handle on front for carrying it, but I found myself trying to use the actual handle pick it up, only to have that pull up as though I was getting ready to start cleaning with the machine. Sometimes when I was moving the vacuum, I would accidentally hit a button, and the handle would detach and the whole thing would collapse in response. The eponymous ball helps the vacuum maneuver pretty easily. It was good at fitting into tight corners. However, because it’s so bulbous, it did limit my ability to get the vacuum all the way under some folding chairs. The vacuum is mostly plastic, and there are a lot of red buttons all over the place. There’s one for lowering the handle, one for detaching attachments from the hose, a slider button on the cleaner head for changing the suction from “powerful” to “max.” Even the power button is red. These are mostly easy to use, but I did sometimes have to try multiple times to release the hose from its compartment.

One upgrade Dyson made to the Compact Animal’s design for the Small Ball affects how the vacuum remains upright. To activate the cleaning head’s roller brush bar, the handle has to be at an angle, which happens when you tug the handle backwards with a bit of force. You push it back upwards to lock it upright, and Dyson says it has a new magnetic lock to help it stay in place. Dyson also says the new vac is 30-percent quieter than the Compact Animal. The Small Ball is made to work on both hardwood and carpet, but it has a special button that stops the roller brush from rotating. On earlier models, Dyson recommended flipping the switch for delicate flooring and rugs, but that’s not necessary with the Small Ball. When I dumped cereal or rice on the floor (for testing, not just because I’m messy), the Dyson would sort of push a lot of the debris around the floor before eventually sucking it up. The vacuum picked up almost all 100 grams of our test messes, but for the cereal, it took almost two minutes to get everything in the canister.

I had to pick up the vacuum so I didn’t shove everything into a corner under the counter. Its maneuverability actually helped here, making it a bit like a ballet, but I’d rather just have it clean everything up on the first pass. When I dragged the Dyson backwards through the flour, for example, it ended up blowing it around a bit. It definitely would’ve been faster to grab a broom. On carpet, however, it quickly suctioned up every mess I threw down, picking up nearly 100 percent of the debris. This mighty mite brings the power of a Dyson to smaller spaces. Though not specifically made for pet hair, the Small Ball performed well in our tests, both with the roller brush and the brush attachment. I didn’t even miss the specialty pet-hair tool, which the Compact Animal comes with. It’s important to be able to clean your dust-filled dustbuster, and Dyson makes it fairly easy — though sometimes it feels like you’re lining up a codex to get everything situated properly to open things up.
