Negative Air Machine

Negative Air Machine

In a hazardous environment, contaminated air is removed using a negative air machine. Through ducts that travel out the window or into the HVAC system, the air is subsequently purified and expelled outside the area.

Negative pressure is produced by drawing air into the machine and venting it outside the room, which helps prevent the transmission of dangerous particles to people outside the negatively pressurized area.

In indoor locations, LakeAir’s negative air machines purify the air and aid in preventing the spread of airborne contaminants. They are also known as air scrubbers, and they have a higher airflow and are more effective air cleaners.

LakeAir’s industrial-grade negative air machines are used in abatement, restoration, building, and demolition applications to remove dust, lead, mold, debris, and other contaminants from the air. In applications like virus containment and patient isolation in healthcare institutions, medical-grade negative air devices clean the air by removing allergies, viruses, and other impurities.

Advantages of Using LakeAir's Negative Air Machine

LakeAir’s negative air machine generates negative pressure inside the enclosed space, which is a benefit. As a result, there is a reduced possibility of polluted air escaping from space. Instead, the room’s negative air will prevent air from leaking out of it.

Mold remediation is a situation in which negative air might be used. The removal procedures cause surface disruption, and mold spores can fly into the air and spread throughout the building. This is a bad condition because mold spores that settle on surfaces might encourage cross-contamination, which could make the mold problem worse.

This risk is reduced by establishing containment around the area that is cleaned up. LakeAir’s negative air machine can be used to create negative air pressure in the room, which can help lower the risk of contaminated air escaping through small holes and cracks in the containment barrier and other nooks and crevices in the walls and room, helping to reduce the risk of further contamination.

Furthermore, at LakeAir, we’re dedicated to green manufacturing principles that go far beyond just energy efficiency.

Filters that Help Negative Air Machine Work

The blower and several filters that are included with LakeAir’s negative air machines help to maintain the air’s safety and cleanliness.


Pre-filters function in the initial step of filtration to capture the biggest particles in a specific area. The device can process more cubic feet per minute, maintain airflow, and improve filtering effectiveness by capturing these bigger particles.

Optional Medium Filter

A medium filter or a second-stage filter is part of some units. The pleated form of medium filters helps to capture particles and safeguard the carbon filter.

Optional Carbon Filter

When pollutants enter an activated carbon filter, they are absorbed, and then the gaseous pollutants and odors are retained in the carbon substrate. This process is known as carbon filtering.

HEPA Filter

The very smallest particles, such as dust, mold, germs, and other irritants that aggravate asthma, lung diseases, or prolong illness, are captured in the final stage of filtration.

High-efficiency particulate air (HEPA) systems, which are nearly 5,000 times smaller than the average human hair, are specifically made to collect 99.7% of dust particles that are more or equal to 0.3 microns in diameter.


A trustworthy blower is necessary for air scrubbers since it draws air into the machine, filters it, and then exhausts the filtered air outside. Without a blower, the filters would quickly clog and the machine would be less effective at purifying the air and generating negative pressure.

HEPA Filters and LakeAir's Negative Air Machine

High-efficiency particulate air filters are capable of removing many smaller particles than a normal filter. A number of other filters that are designed to filter out bigger particles also include an optional HEPA filter.

A HEPA-rated filter has a 99.97% efficiency rate for removing particles as small as 0.3 microns. This is particularly crucial in some workplaces where there is a higher chance of exposure to pollutants.

LakeAir’s negative air machines are portable filtering systems that draw in and remove airborne particles to improve air quality. These air cleaning devices are able to successfully remove a variety of airborne diseases, including mold, fungal spores, and even odors, because of their high-rpm motors, upright-type cabinet designs, and high-efficiency backward-curved blowers.

Why is a HEPA Filter Required?

Our negative air machine can remove even more particles than it can with regular filters thanks to the addition of a HEPA filter. These filters are capable of removing tiny traces of things like mold, germs, lead, dust, asbestos, and other things.

Air purification devices continuously remove impurities from the air. However, HEPA-filter-equipped negative air machines are far more effective at doing the job. Other filters in the system will capture bigger particles like dust and animal hair, but depending on the environment you’re in, some particles can only be removed by a HEPA filter.

Reasons to choose LakeAir’s negative air machine:

  • It enhances the health and productivity of all occupants of a location, as well as the quality of the air in general.
  • It can stop allergies, asthma, and lung irritation.
  • It is widely utilized in the nuclear, aerospace, technological, pharmaceutical, and nuclear power industries as well as in private residences and business buildings.
  • It consists of thousands of extremely thin strands that are organized specifically to catch trash that is too small to be caught by ordinary filters.
  • It guarantees to capture 99.97% of the dust.

Provide a Healthy Space for Your Family or Staff with LakeAir

In medical institutions, factories, commercial buildings, job sites, and tight spaces containing mold, asbestos, or lead, negative air machines are used to create positive or negative air pressure and clean the air.

Positive or negative air pressure can be produced using negative air machines, which are essential for creating secure healthcare conditions.

Positive pressure shields those inside the room by preventing outside air from entering and hurting immunocompromised patients, whereas negative pressure isolates a space and stops the spread of infectious germs from a room.

Frequently Asked Questions:

A negative air machine is a device intended to increase the safety and comfort of an interior environment by filtering out harmful substances. The device removes contaminants from the air by producing a negative pressure in the space and passing the air through a series of filters. The purified air is then released back into the space, diluting the noxious odors and gases. As the machine constantly draws in air, processes it, and then releases filtered air back into the room, the process is also perpetual. Allergens, dust, mold, and other particles may be removed from the air with the use of a negative air machine, which is widely used in both homes and businesses.

There are several advantages to using a negative air machine, including enhanced indoor air quality by lowering allergies, dust, mold, and other airborne particles. This can result in enhanced indoor air quality and respiratory wellness.

Negative air machines are also useful for controlling construction dust and debris during remodeling or renovation projects, as well as for containing contaminated air. They contribute to an increase in energy efficiency by shielding the HVAC system from contaminants and eliminating smells. In addition, negative air machines may shield interior air from external toxins, making them a valuable tool for producing a better indoor environment.

Overall, the use of a negative air machine can have a positive impact on indoor air quality and indoor comfort.

Negative air machines equipped with HEPA filters can effectively remove a wide range of contaminants from the air, including dust and debris, allergens, mold and mold fragments, bacteria, pet dander, smoke particles, volatile organic compounds (VOCs), chemical odors, dust mites, and even virus particles under certain conditions. These filters work by trapping particles as air is drawn through the machine and filtered, resulting in cleaner air being expelled back into the room. While the ability of negative air machines to remove virus particles may depend on various factors such as room size, flow rate, and airborne virus concentration, they can still be an effective tool in reducing the concentration of airborne contaminants in a room.
