Before finalizing an external oral suction one must understand its mechanism. An external oral suction unit has two main parts.

Suction unit: Suction Unit arm length must be long enough to provide enough space to work together with assistant. 4 hand dentistry needs at least 1.5 meters or above suction arm length. Heavy power above 1000 watt gives more power to suck aerosols.

Sterilizer unit (Like Air Purifier): To disinfect the aerosols sucked, a good extra oral suction need 4 main filter mechanism. Primary filter+ UV light+ Plasm Ions + HEPA filter.

Tips for choosing a mobile aerosol suction unit

Don’t be misled by the number of negative pressure. Check the rated airflow (CFM or L/min). The greater airflow rate, the higher suction air velocity and dynamic pressure.

Choose a device that uses a HEPA filter,the gold standard for aerosol suction units to capture the airbone.

Make sure there are UVC lights for additional disinfection.

Find a product with good after-sale support and reputable manufacturer.

Figure out you want a more flexible suction arm or the one can last longer and better look.

Look at noise levels (listed in decibels) in product specs. Depending on where you’re using your aerosol suction unit, you may want a quieter device. Check if the motor speed can be adjusted to lower the noise level.

Calculate the aerosol suction unit’s ongoing maintenance and electricity costs so you can budget beyond your initial purchase.

Skip the bonus features, such as app integration, foot control and plasma, unless money is no object.

Figure out where you want to place your aerosol suction unit so you can choose the right size for your space.

What to look for in an aerosol suction unit

You will find all kinds of portable aerosol suction system or external suction unit in the market this year. You might want to know how to find a right one for your office. We’ve assembled a list of things to consider when searching for an aerosol suction unit to fit in your office..

1. Suction power– should we look at motor power (watts), pressure rating or airflow rate?

2. Cost of Replacement Parts: 

Find out what it costs to replace filters and other parts. Make sure it is easy to access the filter chamber. Do you want to pay extra for technician to do maintenance?

3. Electricity Costs:

Know how much it costs to run an electronic air cleaner.

Learn about the warranty available for the unit you are considering. Normally the cosmetic and consumables are not covered in Warranty.

5.Indicator Lights or alarm for Filter Changes: 

Some units have them. It’s not necessary, but is kind of convenient.

6.Noise Level: 

You want this to be as low as possible, but realize some of the high capacity aerosol suction units do make noise. Working in a noisy environment for a long time can be painful. Also make sure the unit come with speed adjustment function to lower the noise level if necessary.

7.Multi-layer Filters:

Does the unit have a pre-filter and middle layer of filter to increase HEPA filter efficiency? A pre-filter and middle layer filter can make the HEPA filter last longer with better efficiency.

Size and Look of the Aerosol suction unit: Some aerosol suction units are big and ugly. Others are sleek and pleasing to the eye.

8.Choice of suction duct/pipe

Some people like the convenience of flexible duct. But many others prefer the better looking and sturdy aluminum arm. Based on our observation and experience, the flexible duct doesn’t last as long as the aluminum arm/pipe.

4 Considerations to Keep in Mind When Choosing a Portable Fume Extractor

One of the main benefits of a portable weld fume extractor is the ability to move it around your facility or weld site with ease. This increases the likelihood of dings and dents, so it’s imperative that the unit be built to last. Look for an extractor with heavy-duty stainless steel cabinet construction featuring 100% welded seams. Welded seams and a durable cabinet will prevent against leaks, and leaks are the enemy of clean air.

Often times, those who are researching portable fume extraction units – such as weld training facilities, small-scale project welders and mobile service people – could benefit from a variety of source capture units to match the diverse nature of the work they perform.

Just because the unit is portable doesn’t mean performance should be sacrificed. While features should be scaled to an appropriate degree, they should not be removed altogether. High-performance blowers and pulse cleaning filters are features you should look for in top-of-the-line portable weld fume extractors.

Welding processes, aside from creating toxic fumes, generate a lot of sparks as well. Portable weld fume extractors should incorporate spark arrestance technology to prevent sparks from turning into full blown fires during the ventilation process. This process is most effectively employed by extinguishing sparks before they have a chance to reach the dust collector and filter media.

Some Ozone Generator Know You Should Know

How Ozone is Produced?
Ozone Production from Smog
Ozone is formed at ground level by a chemical reaction between Nitrogen Dioxide (NO2) and/or Volatile Organic Compounds (VOC’s) and UV rays from sunlight. The difference between this unhealthy ozone production and commercial ozone production, or natural ozone production in our ozone layer, is that ozone production from smog is an unhealthy cycle that is hard to break. In ozone production from smog the air quality is altered long term, ozone does not simply break down into harmless oxygen, but instead recombines to form NO2 in the atmosphere and re-start the unhealthy cycle again. See image below for example.

How to Test Ozone Generator Performance?
Ozone generators are sized based on the amount of ozone they produce. This article intends to help you understand how to test the production of your ozone generator machine .
There are different methods used, and different equipment required for measuring production from each of these styles of ozone generators. Both methods are covered in the linked instructions. Below are some details on each, this should help you understand the right instructions to use for your ozone generator.

How to read performance chart?
How to read Ozone Generator performance charts
Every ozone generator has ratings to describe the output of ozone in relation to other ozone generators. These ratings are derived from performance testing of an ozone generator. When ozone generators are tested a Performance Chart should be created to understand the performance of that ozone generator across the full scale of normal operation.The chart below is an example of an ozone generator performance chart. This is the format we use at Oxidation Tech, you may have a different chart with a different format, however many of the same fundamentals will be the same.

Ozone Generator Performance Chart Defined
Importance of an ozone generator performance chart

Ozone generator performance must be measured and tested to quantify the production of ozone. For most applications, ozone production is the number one factor in choosing an ozone generator for that application. Therefore, it is imperative a reliable performance chart be reviewed prior to the purchase of any device that may produce ozone.

Four Reasons Why You Should Avoid Ozone Generator Air Purifier

Not only is ozone potentially dangerous to your health, it may not even work at all. Below are four reasons why you should never use an air purifier that produces ozone.

  1. Ozone Generators May Not Work at All
    Some manufacturers suggest that ozone will render nearly every chemical contaminant in the home harmless by producing a chemical reaction. This is incredibly misleading because a thorough review of scientific research has shown that in order for many of the dangerous chemicals found indoors to be eliminated the chemical reaction process may take months or even years.

  1. The Chemical Reaction Can Be Dangerous
    Even if ozone generators were proven to be effective at eliminating these chemicals, there are certain side effects everyone must be aware of. Many of the chemicals ozone reacts to results in a variety of harmful by-products. For example, when ozone was mixed with chemicals from new carpet in a laboratory setting, the ozone reduced many of the chemicals but created a variety of dangerous organic chemicals in the air. While the target chemicals were reduced, the dangerous byproducts rendered the process moved.
  2. Ozone Generators Do Not Remove Particulates
    A third factor to consider when looking at ozone generators is that they do not remove particulates such as dust or pollen from the air. This includes the particles which are primarily responsible for allergic reactions. To combat this, some ozone generators include an ionizer which disperses negatively charged ions into the air. In recent analysis’s, this process was found to be less competent in the removal of air-borne molecules of dust, smoke, pollen, and mold spores than HEPA filters and electrostatic precipitators.
  3. It Is Impossible to Predict Exposure Levels
    The EPA notes that it is increasingly difficult to determine the actual concentration of ozone produced by an ozone generator because so many different factors come into play. Concentrations will be higher if more powerful devices used in smaller spaces. Whether or not the interior doors are closed rather than open will affect concentrations as well.

Different peoples have different ideas, in facet Ozone Generator Air Purifier can effectively eliminates virtually cigarette/cigar smoke, pet odors, paint/cleaning fumes, dust, water damage, smoke damage, cooking odors, and other air borne irritants.
