A New Level of Performance and Savings from a New Category of Air Cleaner
The Dynamic V8 is the new standard in air cleaning–outperforming anything on the market in contaminant control, maintenance and cost of ownership.
Designed to meet the rigorous requirements of Green buildings, data centers, hospitals, pharmaceutical and clean manufacturing, the Dynamic V8 Air Cleaning System couples maximum effectiveness with unparalleled energy and operational savings.
The Dynamic V8 utilizes both the principles of existing Dynamic products as well as several important technological advances to create a system that is a quantum leap over the current state of the art.
In the past you had to choose between air quality and operating costs: Now you don’t.
The New Standard in Air Cleaning
The Dynamic V8 provides MERV 13-15+ performance without ionizing or Ozone generation– plus VOC reduction and superior capture of dangerous ultra-fine particles. It is constructed to eliminate bypass, a critical issue for maximum performance. Further, because of the various mechanisms of the Dynamic V8, the MERV results understate the real-world effectiveness, as shown below. A typical MERV 14 passive filter will fail to trap four times as many 0.3 micron particles. In actual installations, levels of ultra-fine particles and black carbon were over 90% lower than outdoor levels.
Figure 1 The graph above shows particle counts at 0.3 microns as a function of air changes in an AHAM chamber. The Dynamic V8 surpasses all others with its superior dust holding capacity.
Note on Filter Testing
As stated in the standard, the MERV test is a test for passive filters and not truly applicable for active and electronic air cleaners because of the highly conductive loading dust used (typical atmospheric dust is not conductive). Because of the absence of a universally applicable performance test, many rely on the, ASHRAE 52 test. In the standard MERV test with conductive dust, the Dynamic V8 starts as a MERV 15, briefly drops to a 13 and winds up a 14. But since the “M” in MERV is for “minimum”, the V8 is a MERV 13. When the MERV protocol is followed using non-conductive dust (MERV-NC), the V8 achieves up to MERV 15. (Tests performed by Intertek and Blue Heaven)
In a highly urban environment, the Dynamic V8 provided indoor air with levels of ultra fine particles and black carbon from vehicle exhaust that were over 90% better than the levels in the outdoor air.
As of September 2010, the first Dynamic V8 installations have been in service for over 2 ½ years. No pre-filters are used. Pressure drop has increased only .2” w.g. The air cleaners will have many more months of operation before the media needs to be replaced.
On two projects, one using Dynamic V8 air cleaners in small fan coil units (ASHRAE headquarters) and one using Dynamic V8 air cleaners in a large custom AHU (Downtown Washington DC), the counters below show the maintenance interval run time from the last filter change until today.

The least expensive filter is the one that you never put in.
Lowest Life-Cycle Cost/Longest Life
- Energy, maintenance and disposal account for over 90% of the cost of filtration.
- The Dynamic V8 slashes all three to deliver operating costs that are 1/3 that of alternatives.
- Typical paybacks are less than three years.
The Dynamic V8 holds up to ten times the dust of standard cartridge and bag filters and up to 100 times the dust of shallow-bed passive filters, as shown in Figure 2. Loading is critical to the ongoing costs of filtration, but is often overlooked or not reported. Unlike passive filters (which load primarily on the face of the media), the Dynamic V8 loads throughout the full 1” depth of each of the eight media pads and 360° around each fiber. This three-dimensional loading accounts for the V8’s dramatic ability to collect contaminants. And the active-field technology tightly holds what has been collected so it is not shed back into the airstream.
Figure 2. The graph above shows pressure drop as a function of dust load.
Longest Maintenance Cycles
Dramatic loading means a typical maintenance cycle should be over three years. That means no quarterly pre-filter change outs and nine-month final filter replacements. That frees up a lot of time for maintenance personnel to concentrate on other things. Less media changes also means less material use, less disposal costs and a smaller environmental footprint for the building.
The least expensive kilowatt is the one you never use.
Maximum Energy Savings
Superior loading also flattens the pressure drop curve to save over 1” of static. This means big energy savings and the potential for smaller fan selection. Energy costs are a major concern for facility managers and are, at current rates, typically 80-85% of the cost of filtration, far outweighing initial filter cost. A MERV 14 cartridge filter array with pre-filters will consume three times more energy than a Dynamic V8.
Green Design and LEED
The Dynamic V8 is completely consistent with the goals of LEED and Green Design: it does more with less: more IAQ, less energy, less time, less waste. It is the choice for LEED projects and is installed throughout the LEED Platinum renovation of ASHRAE Headquarters and in numerous projects around the world. Whether you are seeking LEED certification or simply designing with Green priniples in mind, the Dynamic V8 provides the highest level of performance with the minimum environmental footprint.
V8 Energy & Carbon
On a 20,000 cfm air handler, the V8 can save up to 30,000 kWh and 40,000 pounds of CO2 per year versus passive alternatives.

It’s exciting to know we have a beautiful, state-of-the-art facility that is not only safe for our children but also environmentally friendly.
Baker Center Manager
It has been almost three years and we have still not needed to change the media - which today is running at a low ½ inch. The air quality is outstanding. I have found Dynamic to be among the top HVAC companies when it comes to responsiveness and the service has been excellent.
Director of Plant Operations
We have been completely satisfied with all of the Dynamic Air Cleaners. They have met our expectations and performed just as promised. We attribute the odor removal to the Dynamic V-Banks.

The feedback we received was that once the Dynamic filters were retrofitted into the existing air handler and in the new Phase One units, the jet exhaust odor complaints stopped. We were originally skeptical, but that was the first indication that the Dynamic Air Cleaners really did perform well.

The Dynamic V8 outperforms anything in the market.

Configurations and Applications
The Dynamic V8 Air Cleaner can be configured and fine-tuned for a wide range of applications and equipment types. The Dynamic V8 modules can be factory or field installed in the filter section of air handlers configured for high-efficiency passive filtration. Because of its low pressure drop and flat loading curve, the Dynamic V8 can also be used with smaller equipment such as packaged rooftops, fan coils, heat pumps, and VRF units. Here, the Dynamic V8 modules are installed and accessed in external filter sections.

Like previous generations of Dynamic Air Cleaners, the Dynamic V8 Air Cleaning System utilizes active-field technology to polarize both media fibers and airborne particles. The polarized particles are then drawn to both the fibers of the media and other particles. This process brings about a deep cleaning of the air.
The Dynamic V8 utilizes these basic physical principles and couples them with patented developments in material and composite chemistry and media fiber design. The result is revolutionary performance and a new level of energy and operational savings.
