A Dentist is always the most prone professional person for aerosols transmitted infections including viruses like Ebola, SARS, COVID, influenza, etc. In spite of taking maximum protection like a face mask, head cap, gloves, and apron, he is still prone to aerosol transmitted viral infections.

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.

Comparison of a 200 Watt High Efficiency motor and 1800 Watt motor

The electricity cost is $0.15/kWh * 1800 hrs * (1.8-0.2) = $432 with assumption of 1800hr run time and utility rate at 0.15/kWh

4. Warranty:

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

Durability
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.


Flexibility
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.


Performance
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.


Safety
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.

Professional welding workshops utilize welding fume exhaust systems that remove fumes and harmful smoke during all jobs related to welding, including grinding and cutting. Welding processes produce gases and fumes, all of which are extremely hazardous.Welding fumes kill, and there is really only one way to get rid of them and that’s by using an effective welding fume removal system the will get rid of smoke and fumes.You should take the above factor into consideration when selecting a excellent fume extractor. So whether you have a small welding workshop or an operation that involves massive production lines or unique manufacturing processes, there is a welding smoke extraction system that will meet your needs.If you have any problem in choosing dental lab welding fume extractor, you can feel free to contact us at dentalsalemall.com.
