Achieving the best results with our equipment in specific industries often includes understanding the features of our machines and/or the accessories that will best assist you in your job.  Here we provide a few observations and elaborations that may help you in your research.

Using Air Filtration & Dust Collectors

Managing Dust during Medical Facility Maintenance and Renovation

Bag Filter in Housing

Many activities during hospital renovations, construction and demolition projects release large amounts of dust which could be threatening to workers health and impact the successful completion of the project.

OmniAire air filtration machines can be equipped with HEPA filters or with bag filters to remove construction dust from the air at work place. The Bag Filter with a housing adapter can be quickly installed in place of HEPA filter, creating a portable dust collection system. Our bag filters with MERV14 efficiency, are very economical filters for collecting and holding large amounts of dust and debris which would quickly clog an expensive HEPA filter.


  • Demolition Work
  • Sheetrock Finishing
  • Sanding and Grinding
  • Woodworking
  • Painting/Finishing
  • Concrete Sawing


Flexible hoses can be attached to the OmniAire dust collector to collect dust from the point of creation and discharge clean air to any area needed. Improving the air quality in the workplace may increase employee productivity and decrease allergic reactions to airborne pollutants.

Dust collector bags and housings are available for the following machines:

Using HEPA AIr Scrubbers

Choosing HEPA Air Scrubbers for Contained Projects

OmniAire air filtration systems are used as air scrubbers to purify air or negative air machines on all types of hospital renovations, demolition, construction and renovation projects. The OmniAire air filtration machines are available with airflows from 50 to 18000 CFM and are equipped with 99.97% HEPA filter. For a control of construction dust, some larger machines are available with MERV14 bag filters in place of HEPA.. OmniAire machines have a reputation for quality construction, reliable service and are often used on projects where DOP efficiency or equivalent tests are required before the equipment is used on the project.

OmniAire HEPA negative air machines are sold throughout the U.S., Canada and are exported worldwide. To assure our product electrical safety, machines are tested by TUV laboratories to comply with UL and CSA/IEC safety requirements.


  • Variable Speed Control – infinite air flow adjustments for greater versatility
  • Great Portability – large, non marking casters, compact size, light weight
  • True HEPA Filters – 99.97% and 99.99% @ 0.3 micron efficiency, wood or metal frame
  • Economical to Operate – uses standard size HEPA filters, 12” deep
  • Quality Metal Cabinets – smooth surface for easy cleaning, easy maintenance
  • Safe to Operate – tested to comply with UL and CSA electrical standards and OSHA

Optional Accessories for Restoration

Equipment Size

As projects vary in size, accessibility and types of contaminants, the size of the equipment has to be considered. OmniAire HEPA negative air machines prove airflows from 50 to 18000 CFM, come in many sizes and configurations. To accommodate the variations of the required air flow, our variable speed controller is standard on most of our equipment.

Need Custom Equipment?

If our specification sheets do not match your requirements, please contact us. We have a number of custom accessories such as higher efficiency filters, audible alarms, hour meters and other safety items. Most of our machines are also available with 230V 50/60Hz motors.

Air Filtration Machine vs. Neg Air vs. Air Scrubber

In general, these names are just a marketing terminology. When and air scrubber is used to create negative pressure in containment, it is often called neg air machine. When used for recirculation and purification of air in open area, it could be called air scrubber or air filtration machine. OmniAire machines are built to provide a high quality service in any environment and application. Your specific requirements regarding airflow, type of project, accessibility are the important factors in choosing right equipment for you. See our Comparison of OmniAire HEPA Air filtration machines.

Why UL/CSA testing?

For the safety of the users and the acceptance of the equipment on governmental, hospital renovations and many other projects, equipment has to meet the requirements of the applicable electrical codes. To verify the UL & CSA/IEC safety compliance and listing, each machine has an identification label with name of NRTL which performed the test and the manufacturer file number.

Why is Negative Pressure Containment Used?

Use of negative pressure containment with HEPA air filtration prevents spread of asbestos fibers, mold and other contaminates to the outside of contained work area, All exhausted air is purified by HEPA negative air machine to create negative pressure and required air changes (ACH) inside the contained work area. In order to create a negative pressure environment more air must be exhausted from the space then leaking in. . See our Air Flow Calculator to assist you with your airflow requirements.

How much airflow do I need?

Our Air Flow Calculator will provide a quick answer on required cfm and type of machines. Just enter the size of your work area and the number of air changes per hour (ACH). Six or more ACH are recommended for construction and renovation projects. 

How often we need to be changing primary/secondary and HEPA filters?

The frequency of changing filters depends on:

  • Amount and size of airborne dust particulates
  • Airflow requirements
  • High static pressure drop across the filters (see User Manual)
  • Risk of cross contamination from one project to another

Dustlock primary/secondary filter should be replaced when its orange, downstream side shows signs of discoloring by dust. Our dual density poly media captures particulates in full depth of the filter media rather than on the surface, as pleated filters do. The m edia is treated with tactifier to prevent release of captured dust and antimicrobial additive to prevent growth of virus and bacteria. Frequent replacement will help to maintain high airflow and protect the more expensive HEPA filter.

The HEPA filters should be replaced when the airflow decreases below your requirements or when pressure (“WC) across the filter increases to recommended replacement pressure – See User Manual. Some of our OmniAire air filtration machines are equipped with a simple Filter Change light to indicate that filters should be checked or replaced.

HEPA filters become even more efficient when loaded with particulate matter, but the airflow resistance increases and the airflow could be reduced to zero. Average HEPA filter life is 800 t0 1000 operation hours.

What is HEPA filter?

High-efficiency particulate air or HEPA is a type of air filter. Filters meeting the HEPA standard have many applications, including use in hospital renovations, abatement of asbestos, mold and lead, restoration after water damage and many other. The filter must satisfy certain standards of efficiency such as those set by the United States Department of Energy (DOE). To qualify as HEPA by US government standards, an air filter must remove 99.97% of all particles greater than 0.3 micrometer from the air that passes thru the filter. Click HEPA filters for more…

When to use Bag filters instead of HEPA filters?
Our large OmniAire air filtration machines can be equipped with HEPA filters or with bag filter to remove construction dust from the air at work place. The Bag Filter with a housing adapter can be quickly installed in place of HEPA filter, creating a portable dust collection system. Our bag filters with MERV14 efficiency are very economical filters for collecting and holding large amounts of dust and debris which would quickly clog an expensive HEPA filter.
How do I control odors and VOCs without chemicals?

The odor and VOCs can be removed from air with OdorGuard600 and Vapor Trap carbon web filter added to OmniAire machine. For odors associated with water damage, sewer flood, fires and mold, use our PEROx air purifier to destroy safely the source of odor without using chemicals. PEROx unit contains Ionized-Hydro–peroxide generator which is very effective in destroying all types of VOCs, chemical fumes, decay odors, mold spores, virus and bacteria. This purification process is safe for workers and inhabitants.
