TRACS® Model TM-1250 Pro Industrial Air Purification System

Features

Recirculation Option:

As a recirculation unit, the TM-1250 is used to turn virtually any patient room into an Isolation Room, helping to protect health care workers from exposure to contaminated air. The most important aspect of any air cleaner is the air flow pattern created, as only air that passes through the unit can be effectively cleaned and disinfected.  With the TM-1250-P, an excellent air flow pattern is created to ensure maximum effectiveness and contaminant removal.  Air is drawn into the lower end of the unit on all four sides and from the bottom to create maximum air pull, and exhausted from the upper end of the cabinet on all four sides and from the top at a 45 degree angle. This ensures excellent air mixing occurs throughout all corners of the room, preventing dead air spots from occurring on each side of the unit (as can happen when air is only exhausted in one direction).  Furthermore, the height of the TM-1250R-P allows for clear separation of air intake and exhaust, guarding against “short circuiting” of clean air that can occur in smaller units.

Negative/Positive Pressure Options:

The units can be installed to create positive or negative pressure, depending on the location of the unit and exhaust air.  To create a negative pressure room, (such as for a TB Isolation Room or a bronchoscopy/sputum room), the unit should be installed in the room where negative pressure is desired, and the exhaust air should be sent out of the room.  To create negative pressure in a TB isolation room as per CDC guidelines, exhaust flows of at least 10% greater than supply air (but no less than 50 cfm) must occur, and all existing return air should be blocked off.  For instance, a room having 300 cfm supply air must have at least 350 cfm exhaust (because you need at least 50 cfm more).

To create a positive pressure room, (such as for an operating room or immune-deficiency room), the unit should be installed outside of the room where positive pressure is desired, and the exhaust air should be sent back into the room.

Combination UVGI/HEPA

Having both technologies provide double assurance that the air is completely clean and safe.  Moreover, HEPA-only units are less efficient at removing viruses and can have problems with interior bacteria/microbial growth, while UV-only units provide no particle reduction at all.

Low Replacement Costs

UVGI not only enhances the effectiveness of the unit, but it also reduces the replacement costs, thereby increasing the overall efficiency.  The most expensive replacement cost of any similar air cleaning device is the HEPA filter.  In HEPA-only systems, mold and microbial growth can occur on the HEPA filter, so HEPA filters should be replaced at least once per year (even if the HEPA filter is not clogged). If they are not replaced, the microorganisms can actually eat through the HEPA media (this is known as bacteria grow-through), and ruin the integrity of the filter (and the overall air cleaning system).  However, with the TM-1250, the entire HEPA filter is constantly bathed in UV light, so mold and microbial growth cannot occur.  Given this and a prefilter that will take out larger dust particles, the HEPA filters in our systems can last up to three years (depending on particulate load), thereby lowering unit maintenance costs.  Lastly, all replacement filters are standard sizes, keeping costs at a minimum and even allowing for local supplying of them if necessary.

HEPA Locking Mechanism

The galvanized HEPA filter in the TM-1250 is mechanically sealed into place to prevent air bypass around the HEPA filter.   Pressure applied by thumb screws compresses the HEPA’s gasketing against the HEPA shelf to create a tight seal and ensure the unit’s efficiency.

Mobile Option

The TM-1250 is easily transported throughout the facility on heavy duty 3” locking casters.  A convenient handle is located on the side of the unit to allow for easy navigation and movement through the facility.

Ease of Conversion to Negative Pressure/Recirculation System

The TM-1250 comes standard as a negative pressure unit with a 12” collar on the top for duct connection.  However, if in-room air recirculation is desired, the unit can quickly and easily be converted into a recirculation system by simply installing the recirculation top four screws.

Location of blower

As recommended by ASHRAE and hospital guidelines the blower in the TM-1250 is located after the filtration technologies (specifically the HEPA filter), thereby preventing contamination of the blower components.

Compliance with CDC and OSHA Guidelines

The technology and type of function provided by the TM-1250 is endorsed and recommended by the Center for Disease Control for control of Tuberculosis and other infectious disease.  As such, when using the TM-1250 correctly, facilities comply with CDC and OSHA standards for infection control.

Safety Interlock

A safety interlock mechanism is in place that will automatically shut down all power to the unit when the access door is opened.  This prevents direct exposure to UV radiation and to any powered electrical components.

Full Variable Speed Control

Allows for use in a wide range of rooms both small and large.
