Multi-Stage Filtering System
When diesel fuel burns in an engine, the resulting exhaust is made up of soot and many harmful gases which may contain thousands of different chemical substances.
Diesel exhaust fumes contain carbon monoxide, oxides of sulfur and unburned and partially burned hydrocarbons. These chemical compounds and gaseous pollutants attach themselves to tiny particles, circulate on air currents and adhere to walls, offices, stairwells, fire engine hoses, kitchen areas and sleeping quarters. Diesel exhaust can spread quickly through an entire building where it can darken walls and settle on food and clothing, creating an indoor air pollution hazard.
Because of the number and complexity of pollutants involved, the AirMATION® houses a progressive filtering system, comprised of various levels of mechanical filtration and activated carbon. The multi-stage progressive filtration system is designed to remove airborne particulate, contamination, gaseous pollutants and diesel soot.
AirMATION® units automatically operate to clean the fire station air. After vehicles return from a run and the engine is shut off, AirMATION® continues to remove gas phase pollutants from engine components. The Timer Control and Maintenance Monitor (TCMM) is preset for approximately 21 minute operation with a maximum of 180 minutes. Using the manual override feature for 24/7 operation enables the AirMATION® units to remove off-gassing from turnout gear, engine fumes and smoke and soot smell from hoses.
The result is a safer, cleaner environment for your firefighters and EMS personnel.
Each AirMATION® unit contains a blower rated at 166,000 cubic feet per hour with the filters in place. The baffle box re-directs clean air to the bays in such a manner as to eliminate dead air pockets, dirty air stratification and stagnant air.
There is low electric usage and no building or vehicle modifications are necessary. AirMATION® accommodates all ceiling heights, ceiling structures and multiple heating systems. There is no fan maintenance, which is encountered in most other systems.
The AirMATION® AMB-302 Unit:
This unit is comprised of a direct-drive blower and a three-stage progressive filtration system. Purified air is reintroduced into the facility through a diffuser that helps to deaden air-turbulence noise while directing the clean filtered air throughout a facility. An air pressure circuit continually monitors the status of the filters. When the air volume falls below a factory pre-set level due to filter loading, a visible, red warning lamp is activated to indicate that filter maintenance is necessary.
1st Stage: 4-inch Pleated 30% Pre-filter Panel
Filter media is composed of a blend of high loft synthetic and natural fibers for arresting more than 90% of particulate as small as 4 microns (MERV 8) in size. The media is water resistant and this pre-filter is designed to last 1,000 runs or longer depending on environmental conditions. Diesel soot and larger particulate are also removed at this stage.
2nd Stage: 95%/98% V Bank High Efficiency DOP Cell Particle Filter
This 24" x 24" x 12", measuring 200 square feet of smaller high efficiency ultra-fine glass fiber media, removes particulate as small as 0.3 microns. It removes the finest sub micron particles and diesel particulate. This is a 95%/98% (MERV 16) DOP Filter (DiOctyl Phthalate), hospital grade filter. Designed to capture particulate in the .3 to 1 micron range and smaller. This filter is moisture resistant and has a UL Class 2 flammability rating. It is also designed to function in 100% humidity environments and remain effective for approximately 10 to 48 months or greater depending on environmental conditions and running time.
3rd Stage: Gas Phase 12-inch V Bank Carbon Filter Cell
This gas phase filter contains 26 pounds of activated granulated coconut shell carbon blended with potassium permanganate to remove
gaseous pollutants and foul odors from the air stream, including the sulfur, aldehydes and VOCs
associated with diesel fumes. Measures 24" x 24" x 12" and fits into a pre made track.
4th Stage: Auto-Roll Filter Attachment
Optional Pre-Filter Protection Stage Auto-Roll Filter Attachment
The AirMATION® AMARB-302 Unit
The Auto-Roll filter,is a Pre-Filter Protection Stage added for an extra level of filtration. The Auto-Roll is attached to the front intake portion of the system before the pre-filter stage. The forty inch (40") wide filter media, Reemay acts as a roughing filter that is 83% efficient on 8-10 micron sized particles. The media is provided on a 200 yard roll that is automatically advanced across a 40" X 40" input flange to present a large filter surface-area. Since the filter is very large, this option is ideally suited for facilities with ceiling heights of 18 feet or more. With an inlet surface area of over 11 square feet and 200 linear yards of media per roll, this highly efficient synthetic filter continuously captures a high volume of airborne contaminates before they reach the pre-filter stage.
The addition of the Auto-Roll option makes the unit ideally suited for environments with high levels of airborne particulate contaminants and diesel fuel exhaust fumes, which would ordinarily require frequent pre-filter replacements. In such cases, the Auto-Roll helps to reduce energy, material and labor costs.
The feature is a totally automated function that indexes the filter media take-up spool when the pressure circuits detect that the filter is becoming clogged. A sub-fractional motor moves the take-up spool at a rate of 1 rpm under control of the Photohelic pressure circuits. A Photohelic gauge and pressure switch are mounted on each unit to continuously monitor and the condition of the filter media and to advance new filter material as required. The factory pre-set filter advancement and shut-off points are accessible to the customer along with a manual filter indexing push-button and filter indexing light. The unit's power is protected with a reset cable circuit breaker and controlled with an illuminated power switch.
