OTH SERIES - DIRECTIONAL FLOW AIR CLEANER - 400 & 600 CFM

OTH Series Directional Flow Air Cleaner provides purified clean air for lunchrooms, meeting rooms, and other areas that experience high foot traffic. A simple “Pre-engineered" solution with "Clean-to-less-clean" air distribution, HEPA H14 Filtration (99.995% @ 100 Nanometer), Duct, and Diffusion Hood. The OTH is fitted with hoods that are available in four lengths: 1m (2-4 people), 1.5m (4-6 people), 2m (6-8 people), and 2.5m (8-10 people).

Placed in a variety of settings with medium to high occupancy, the clean filtered air leaves the diffusion hood and reaches the table (roughly 1 meter below) in 1.31 seconds after the Air Purifier module is turned on!

The over-table hood can be mounted horizontally or longitudinally using the provided mounting hardware.

• H14 HEPA Filter
• MERV 10 Prefilter
• Multiple Diffusion Hoods for a variety of applications.
• Duct kits available for different mounting scenarios.
• Availble with activated carbon Deep Bed Absorption module. (Other adsorption media are available)

This solution employs the ventilation method of "Clean-to-less-clean" air movement coupled with HEPA filtration as recommended by the CDC, ASHRAE, WHO and more. By using this system you will immediately achieve 99.995% clean air around the table and after a short while a 98-99% Reduction of the Virus and Bacteria in the rest of the Room.

Airflow from Clean to Less Clean

• More important than having to wait a longer time between room changeover due to lower ACH
• More important than air change rate
• More important than outside air % above 2ACH

By simply having a normal conversation, aerosolized viruses and bacteria can remain in the air indefinitely, therefore it is important to use forced air to direct these aerosols away from the occupants and allow them to be captured by the HEPA H14 fan/filter unit where the air can be filtered and returned to the space. This limits the transmission of respirable viruses such as Influenza, Coronavirus, common cold, etc., thus substantially reducing the risk of being infected. For example, the zone over and around a 6-person table is approximately 10m3. This gives you a total ACH (Air Changes per Hour) of 60 ICA-700 filters.
This solution has a typical payback of 1 year when compared to the costs of 1-week sick leave, per year, per employee.

The systems use a combination of clean-to-less-clean air movement, HEPA Filtration and optional UV light as recommended by both the CDC and ASHRAE. The cleaned air is supplied at a rate of 700 M3/H (400 CFM) or 1000 M3/H (600 CFM) per filter module, directly to the occupants breathing zone. This creates a "Bubble" of constantly filtered clean air around the table and up to 53 air changes in the room.*

Here's how it works:

• STEP 1: The "Clean-to-less-clean" air movement supplies clean filtered air to the occupants breathing zone through a pre-engineered diffusion hood explicitly designed for the application e.g., meeting rooms, lunchrooms, Locker rooms, classrooms, etc. This precise air movement is essential as the viral particles associated with Covid-19 have shown that they can remain airborne, for up to 16 hours in still air.
• STEP 2: An ultra-low noise fan draws the room air in at floor level where the air is least clean. The air is drawn in by a variable speed, a centrifugal fan that allows the operator to control the flow based on the number of people in the room.
• STEP 3: The air passes through a silenced chamber engineered to dampen the associated noise generated by the air movement.
• STEP 4:A multi-stage filter module filters the contaminated air containing virus particles as small as 0.1 Micron (MicroMeters) to a purity level of 99.995%.
• STEP 5: An optional UVC germicidal treatment lamp can be purchased as a supplement to help destroy virus particles that may remain attached to the inner surfaces of the unit's air intake housing.
• STEP 6: Clean filtered air is returned to the indoor space through a low-noise duct and diffuser hood detailed in Step 1, thus completing the filtration and ventilation circuit. This allows the air in a typical room to be changed over 100 times an hour.

Each system Fan/Filter module complete with four-stage filtration:

1. Prefilter for larger particles >50 microns. (Washable)
2. High-efficiency F5 class secondary filter 40-60% efficiency on particles larger than 0.4 microns. (Disposable)
3. High-Efficiency HEPA H14 class final filter 99.995% efficient on particles smaller than 0.1 microns. (Delivered with Efficiency and leak test Certificate)
4. Outlet filter of washable Aluminum mesh (Washable)

Additional Information:

• All ICA air-purifiers come complete with 120V variable-speed EC motors. Units are delivered ready to plug in and use. The fan speed can be adjusted to suit precise ‘Draft-Free’ airspeeds and ‘Ultra Quiet’ noise levels.
• When selected, duct kits come complete with lightweight sheet metal ducting, duct fitting, chains (to hang the hood and duct), and hooks (for the ceiling).
• The duct kit, hoods, and/or supply arms are simple to install and typically require no more than 30 minutes to set up.
• Units are fabricated with heavy-duty, all-steel materials of the highest quality.
• All units are delivered complete with 4x5" diameter locking casters. Alternatively, 5" (125mm) legs can be ordered separately.
• Optional bacteria-killing UVC lamps can be placed before the HEPA H14 filter to kill surface viruses, mold, and bacteria.

• Low Noise Level: The OTH can be used in offices, libraries, and other work environments where low noise is integral
• Clean Aesthetic: our covid units are all designed with appearance in mind. With a clean aesthetic, these units will blend into domestic environments as well as industrial
• Diffusion Hood: Designed to spread the 99.995% Virus and Bacteria free air evenly over the table and without draft, providing immediate protection and filtration
• Easy Installation: The system comes with chains measured for your application, and hooks to screw into the ceiling. Then the system hangs securely, with the ductwork pre-cut to fit perfectly into the filtration unit
• Easy Filter Access: With front access to the filters, changing out and cleaning filters is made quick and effortless, making maintenance intervals much less troublesome
