How Negative Pressure Particle Containment Works

Abatement Technologies HEPA-AIRE® and PREDATOR® series Portable Air Scrubbers (PAS) are designed to contain and capture indoor air particles and other contaminants and odors using a time-proven technique known as negative pressure particle containment. Effective negative pressure containment requires four main elements:

  1. Construction of a physical barrier around the work area to separate it from the rest of the facility.

  2. Sealing off any HVAC return air grills within the space to protect against particles being pulled into the HVAC system.

  3. Continuously pulling air within the area through a HEPA filtration device to reduce the number of airborne particles. Most job specifications require at least 6 air changes per hour (ACH), which means that the device must filter a volume of air equal to the air volume contained within the enclosed space 6 times per hour, or every 10 minutes.

  4. Exhausting at least 10% more cubic feet per minute of clean, HEPA-filtered air out of the space than is supplied into it to create and maintain negative pressure within that space. This helps ensure that any air leakage between the contained area and adjacent spaces will be “clean” air flowing in and not “dirty” air flowing out.

Why is negative pressure important to construction projects?

A negative pressure environment will help to contain the construction dust and contaminants within the construction space. A negative pressure space eliminates the possibility of contaminants passing outside of the construction area through leaks in the construction barriers.

Why do I need to monitor room pressure where I am removing airborne particles, odors and infectious diseases?

Air flows from a higher pressure to a lower pressure. The PREDATOR or HEPA-AIRE PAS creates a negative pressure in the room so that airborne particulates are pulled towards it and filtered out. The negative pressure prevents particulates from leaving the room you want to cleanse and contaminating adjacent areas. Room pressure differences must be monitored and maintained to be effective. The most reliable and sure way to confirm that pressure relationships are correct is to continuously monitor differential pressure using Abatement’s

 

What does the term HEPA mean?

HEPA is an acronym for "High-Efficiency Particulate Air" or "High-Efficiency Particulate Arrestance." This acronym refers to a filter that is manufactured, tested, and certified to meet the Institute of Environmental Sciences and Technology (IEST) construction, performance, and certification standards as currently published in IEST RP-CC001.3.

Principles and Importance of Negative Pressure Containment

Effective Negative Pressure Particle Containment Using Portable Air Scrubbers

Particles released into the air during facility construction, renovation, demolition, and maintenance activities must be properly isolated and contained. Tiny particles and fungal spores are lightweight enough to remain aerosolized (suspended in the air) for hours, days, or even weeks. The aerosolized particles can migrate into other areas of a facility on air currents and pose a potential threat to the health of sensitive patients. Larger particles can create housekeeping problems when they drop out of the air and settle on floors and other surfaces.

Benefits
Contractors and their customers won’t have to contend with the irritating, lingering fumes that are associated with first-generation botanical formulas.
With Concrobium Broad Spectrum Disinfectant II, pros can count on an EPA-registered bactericide, virucide, tuberculocide and fungicide that contains no harmful chemicals. The solution has no warning labels and requires no PPE.

  • EPA-registered bactericide, virucide, tuberculocide and fungicide

  • Botanically-derived formula

  • One-step hospital grade disinfection and cleaning

  • No ammonias, chlorines or glutaraldehydes

COVID-19 (coronavirus disease) is caused by the SARS-CoV-2 virus. Concrobium Broad Spectrum Disinfectant kills similar viruses and therefore can be used against SARS-CoV-2 when used in accordance with the directions for use against Feline calicivirus on hard, non-porous surfaces. Refer to the CDC website for additional information.

luded that Construction Management contracts are a win-win for you and us. As Construction Managers (CM), we serve as agents for owners (you), providing administration and management services from planning through construction. This project delivery method begins at the earliest stage of a project’s concept where we have the greatest impact on the project’s success. We ensure success by instilling transparency, engaging our innovative solutions, and utilizing our vast relationships and expertise through intensive collaboration with you, vendors and trade partners.

This benefits you, by way of, you only pay the actual cost of the materials and sub-contracts with no additional fees, no markups on material upgrades and the ability to control your money. We create a detailed, quantified and realistic budget that allows the project to be completed within budget and on time. 

What are the biggest fears of hiring a contractor?
  

  • Large upfront payments  

  • Poor workmanship

  • Schedules not being kept

  • Unexpected change orders

  • Poor communication

  • Underestimating the scope of work

  • Trade liens on their homes

  • Project cleanliness and safety 

Alleviate these fears with a Construction Management approach; for peace of mind.
Besides our standard General Contracts (one fixed price), we offer Construction Management contracts, which is a win-win for you and us. As Construction Managers (CM), we serve as agents for owners (you), providing administration and management services from planning through construction. This project delivery method begins at the earliest stage of a project’s concept, where we have the most significant impact on the project’s success. We ensure success by instilling transparency, engaging our innovative solutions, and utilizing our vast relationships and expertise through intensive collaboration with you, vendors, and the trades.

"CM" contracts benefit you, by way of, you only pay the actual cost of the materials and labor with no additional builder fees, no markups on material upgrades, and the ability for you to control your money every step of the way. We create a detailed, quantified, and realistic budget that allows the project to be completed within budget and on-time. We are paid a fixed construction management fee through progress payments with no hidden cost. 

  • Forgo Down Payment. You only pay when work is performed. 

  • We perform digital takeoffs of your plans for accurate material quantities to budget your project correctly.

  • We collaborate with online real-time construction scheduling.

  • You avoid paying markups on material upgrades.

  • You receive our Builder discounts on material purchases.

  • We have established clear lines of communication, which is critical to the success of your project.

If a CM contract is not for you, we can enter into a conventional "general contract" agreement.  The choice is yours!
