Introducing…Criti-Clean Ultra FFUs with Ultraviolet-C Radiation or Needlepoint Bipolar Ionization to Neutralize and Remove Airborne Pathogens.

We’re proud to introduce two new options to our industry-leading Criti-Clean Ultra HEPA filtration units in order to more effectively combat airborne viruses such as SARS-CoV-2, as well as bacteria, mold and other pathogens. The new built-in modules include Ultraviolet-C (UV-C) Radiation and Needlepoint Bipolar Ionization.

Our Criti-Clean Ultra fan-powered laminar flow HEPA filter diffuser provides a steady stream of purified air into a room. It is available as a traditional ceiling-mounted unit, as well as a completely portable model that comes on wheels and plugs into a standard wall outlet.

“With the need for cleaner, safer indoor air to help prevent the spread of COVID-19, we’re proud to offer effective, easy-to-implement solutions for all types of buildings,” said Rob Haake, president of AJ Manufacturing. “By adding sterilization technologies to our already proven HEPA filtration units, we’ve added a second line of defense that can help schools and businesses reopen safely.”

The new UV-C Radiation module assists in sterilizing particulates in the air stream and also disinfects the HEPA filter. When microorganisms are exposed to UV-C, the light’s radiation penetrates their cell walls and disrupts the structure of their DNA to neutralize them.

The Needlepoint Bipolar Ionization module produces a stream of negative and positive ions, which attach themselves to microorganisms and render them inactive by depriving them of hydrogen. The resulting larger clusters of particles are also more easily trapped in the HEPA filter.

All Criti-Clean Ultra units include a standard HEPA filter that traps 99.99% of particles as small as .3 micron. They can also be upgraded to ULPA filters (99.9995% at .12 micron).

In addition to standard air supply models that push clean air into a room, both the ceiling-mounted and portable Criti-Clean Ultra are also available as reverse-flow units for creating patient isolation areas. These units draw potentially contaminated air in, then exhaust clean air out of the room through ductwork.

The CARES Act and TCJA Can Make HVAC Retrofits Eligible for 100% Deduction and Bonus Depreciation.

At a time when improved indoor air quality is more important than ever to reopen schools and business safely, tax incentives make this an excellent time to invest in new HVAC equipment. That’s due to the recent Coronavirus Aid, Relief and Economic Stability (CARES) Act, as well as extensions for the 2020 tax year to Section 179 of the 2017 Tax Cuts and Jobs Act (TCJA).

The 2020 extension of the Section 179 tax deduction in the 2017 TCJA means that businesses can take a 100% deduction for up to $1,040,000 million in qualifying nonresidential HVAC equipment purchases for the 2020 tax year. This helps building owners justify replacement HVAC costs vs. repair costs.

As background: In 2017, TCJA changed the rules on bonus depreciation – a tax incentive that allows businesses to deduct a large portion of an asset’s upfront costs, rather than write them off over the asset’s useful life. Under the TCJA, several existing property classifications were removed and consolidated under a single classification – “Qualified Improvement Property” (QIP). Within the Act, QIP was rendered ineligible for bonus depreciation.

The new CARES Act corrects this glitch in the TCJA, which failed to designate a depreciation recovery period for QIP. As a result, by default QIP was subject to a 39-year recovery period like other nonresidential real property. Furthermore, while QIP was entitled to immediate expensing under section 179 (subject to that section’s dollar limitations), it was not eligible for bonus depreciation because bonus depreciation is only available for property with a recovery period of 20 years or less. The CARES Act provides that QIP now has a recovery period of 15 years, thus making it eligible for bonus depreciation. This technical correction is effective retroactively to taxable years beginning in or after 2018.

All this means that now is a great time for building owners to save money when making new HVAC purchase…which is more important than ever now that those purchases can provide cleaner, safer indoor air for the building’s occupants. Building owners should always consult their tax professional about their specific situation, but HVAC sales personnel and contractors should be prepared to inform their customers about the tax advantages available now.

Create safer indoor environments anywhere with our line of Criti-Clean Ultra FFUs.

In the recent past, highly purified air was primarily reserved for hospitals, laboratories and manufacturing clean room environments. But today, after the onset of COVID-19, demand for HEPA-filtered air is skyrocketing – in a wide range of building types where it was rarely, if ever, considered before.

Much of the new interest in HEPA filtration is coming from obvious places, such as doctors’ and dentists’ offices. But that’s only the beginning. Building owners and tenants in all types of businesses are showing unprecedented demand for cleaner indoor air to protect workers and customers. These include everything from general office buildings, to schools, to retail spaces like stores, restaurants, salons and much more.

Fortunately, there’s an effective and efficient way to make the air cleaner and safer in any building – AJ Manufacturing’s Criti-Clean Ultra Fan Filter Units (FFUs). These fan-powered laminar flow HEPA filter diffusers remove airborne contaminants from the stream of air they deliver into a room.

For permanent installations, the Criti-Clean Ultra is available in a ceiling-mounted unit that is easy to retrofit into existing spaces due to its low plenum height of only 13.7″. For temporary and relocatable use, Criti-Clean Ultra also comes in a convenient portable unit that is mounted on wheels and plugs into a standard electrical wall outlet. It can be placed virtually anywhere to continually circulate HEPA filtered air in a room.

The Criti-Clean Ultra is the most powerful FFU on the market, and is packed with a long list of features and benefits:

  • The industry’s highest output, up to 1200 CFM.
  • Energy efficiency (only 42 watts at 90 FPM velocity/450 CFM).
  • Quiet performance (only 45 DBA at 90 FPM, 58 DBA at 1100 CFM).
  • Optional air inlet sensor that measures and displays CFM in real time, rather than relying on outdated computed readings or algorithms based on performance data.
  • Optional built-in LED lights on ceiling-mounted unit to maximize ceiling space.
  • Plus, much more

Reverse-Flow Units Also Available
Both the ceiling-mounted and portable Criti-Clean Ultra FFUs are also available in reverse-flow models that remove potentially contaminated air from a room. These units create a negative-pressure environment that can be used to isolate someone who has – or may have – an infectious disease like COVID-19.

As with any addition to an existing system, we recommend you consult an HVAC professional on how best to incorporate Criti-Clean Ultra FFUs into your building. For more information on the Criti-Clean Ultra, click here.

AJ Reopening

Tips and resources for creating safer work environments when returning HVAC systems back to operation.

Now that states and municipalities across the country are eliminating stay-at-home orders due to COVID-19 – and businesses that had employees working remotely are choosing to return to work – many facilities personnel are concerned about getting their buildings back in operation safely, especially when it comes to their HVAC systems. ASHRAE and the CDC both offer advice on the subject, which we have summarized here.

Prior to a building’s reopening, ASHRAE suggests that facility operators create a strategic plan that includes the following:

  • Create measures to make occupants feel safer.
  • Ensure a supply chain for critical items, such as filters, as confirmed for delivery.
  • Review contractual agreements with tenants with regards to building support.
  • Establish a communication protocol with tenants and include key contacts.
  • Prepare and provide training for tenants on safety measures.

ASHRAE also offers a number of suggestions concerning building HVAC systems, including:

  • Follow the requirements of ASHRAE Standard 188-2018, which has tables to show the typical maintenance on equipment.
  • Consider PPE when maintaining ventilation materials, including filters and condensate. Consult additional guidance before duct cleaning.
  • Check if all the setbacks and setup modes are reversed back to normal.
  • Open outside air intake dampers to their maximum, 100% preferred, four hours minimum, before the reoccupation. The maximum position the outside air dampers may be opened will depend on the time of year, local climate, the temperature and humidity of the outside air, and the capability of the HVAC equipment to condition the outside air so that the system is able to maintain acceptable indoor temperature and humidity. When operating in this “flush out” mode, monitor the system continuously to make sure that unexpected or unacceptable conditions inside do not develop. Upon completion of the flush, the damper positions should be corrected to provide design levels.
  • Check to see that space temperature and relative humidity levels are being controlled to the acceptable setpoints.

The CDC also suggests ways to improve building ventilation to help reduce transmission of COVID-19:

  • Consider using portable HEPA fan/filtration systems to help enhance air cleaning (especially in higher risk areas).
  • Increase the percentage of outdoor air (e.g., using economizer modes of HVAC operations) potentially as high as 100%. (First verify compatibility with HVAC system capabilities for both temperature and humidity control as well as compatibility with outdoor/indoor air quality considerations.)
  • Increase total airflow supply to occupied spaces, if possible.
  • Disable demand-control ventilation (DCV) controls that reduce air supply based on temperature or occupancy.
  • Consider using natural ventilation (i.e., opening windows if possible and safe to do so) to increase outdoor air dilution of indoor air when environmental conditions and building requirements allow.
  • Improve central air filtration:
    • Increase air filtration to as high as possible without significantly diminishing design airflow.
    • Inspect filter housing and racks to ensure appropriate filter fit and check for ways to minimize filter bypass.
  • Consider running the building ventilation system even during unoccupied times to maximize dilution ventilation.
  • Generate clean-to-less-clean air movement by re-evaluating the positioning of supply and exhaust air diffusers and/or dampers and adjusting zone supply and exhaust flow rates to establish measurable pressure differentials. Have staff work in areas served by “clean” ventilation zones that do not include higher-risk areas such as visitor reception or exercise facilities.

AJ Manufacturing offers a range of products that can help eliminate airborne contaminants in a building’s HVAC system through the use of HEPA and ULPA filtration. Contact us for more information.

To meet the growing need for patient isolation due to the coronavirus pandemic, AJ Manufacturing has introduced a portable reverse flow fan-powered HEPA filter diffuser to quickly creative negative-pressure isolation rooms in any permanent or temporary hospital environment.

KANSAS CITY, Mo. (PRWEB) April 06, 2020

AJ Manufacturing – a leading manufacturer of critical environment HVAC products – has introduced a portable version of its Reverse Flow Criti-Clean Ultra™ Fan Filter Unit (FFU) to quickly and easily create patient isolation rooms. The new units were specifically developed to help protect healthcare workers treating COVID-19 patients and to help reduce the spread of the virus.

Like the original ceiling-mounted model, the portable Reverse Flow Criti-Clean Ultra™ FFU connects to existing ductwork and creates a negative pressure environment that removes the air from a patient room and cleans it via the unit’s built-in HEPA filter, keeping airborne contaminants from escaping. The unit comes on wheels for easy movement and can be plugged into a standard electrical wall outlet.

“We’re proud to be able to do our small part to help protect healthcare workers who are treating the growing number of coronavirus patients,” said Rob Haake, president of AJ Manufacturing. “Our plant is 100% focused on producing both our permanent and portable FFU models for as long as they are needed to help stop the spread of the virus.”

In addition to reverse flow units that take in air and remove it from a room, standard FFU models – both ceiling mounted and portable – are also available to bring HEPA filtered air into a room. AJ’s ceiling mounted FFUs offer the industry’s lowest plenum height of just 13.7″, allowing easier retrofitting into existing ceiling spaces.

Criti-Clean Ultra Now Offers Hyper Accurate CFM Monitoring

New Built-In Probe Measures and Reports Real-Time CFM with Unmatched Accuracy

AJ Manufacturing is proud to introduce another first in our long history of innovation: accurate real-time CFM measurement and reporting, thanks to a first-of-its kind probe built into the air inlets of our Criti-Clean Ultra fan powered laminar flow HEPA filter diffusers.

Our engineers worked with industry experts to develop this groundbreaking technology that takes the guesswork out of critical environment FFU performance. Until now, CFM measurement relied upon a computed reading – an algorithm based on performance assumptions – to report CFM. Our revolutionary new probe, however, now senses and reports CFM in real time. That means not only will our Criti-Clean Ultra’s CFM readings be hyper accurate, it will also be easier than ever to verify the necessary air changes per hour to meet requirements for clean room certification.

Criti-Clean Ultra’s real time CFM monitoring also offers a range other benefits, including:

  • True airflow sensing that’s not based on assumptions
  • Field calibration to ensure accuracy
  • Insensitivity to HVAC inlet conditions
  • Not affected by air pressure
