Train Engineers and Bus Drivers are essential workers who come into contact with millions of people daily.  As a result, they frequently incur risk of infection during the Covid-19 pandemic, as well as at all other times.  Therefore, they need protection from pathogens now and into the indefinite future.

By installing a Safety Canopy from the ceiling above the driver or engineer, one provides passive PPE, (personal protection that does not require voluntary actions by the person using it) to both the person under the Canopy and those near him or her.

The Safety Canopy works by pulling the dirty, germ-filled air into its housing to filter it.  Its Air-Cleaning BlowerTM (ACB) filters the contaminated air by separating out dust particles, respiratory droplets, rain and other debris and ejecting them from the air.  The cleaned air then flows through an optional HEPA filter element, if needed, to remove additional germs, diesel particulates, and other tiny contaminants.  The Air-Cleaning BlowerTM then flows the air gently out of the bottom of the Safety Canopy to create a cone of clean air around the person.


This cone of air surrounding the driver provides an effective layer of protection for him/her and also helps protect the members of the public.  This cone of HEPA-filtered air, which is gently pressurized so that it moves outward as it flows downward, helps to block the entry into itself of air exhaled by others toward the driver.  It also captures many of the respirated particles that penetrate the cone and carries them down and away from his or her face.  As an added benefit, the cone captures germs and other respiratory droplets exhaled by the driver and pushes them downward and safely away from the faces of the passengers.

In addition, every germ removed from the atmosphere of the train or bus by the Safety Canopy helps reduce the concentration of germs, dust and other contaminants throughout the entire space as a room air purifier would.

Air Cleaning Blowers, LLC reduces maintenance and other operating costs by using its industrial and military-grade Air Cleaning BlowersTM (ACB).  ACBs clean and blow air without using filter media, and they remove dust, pollen, respiratory droplets, mist, rain and millions of other particles.  Hence, they blow cleaned air without the need for maintaining filter cartridges, sheets or other filter media.  If the system includes a post filter, such as a HEPA element, the ACB greatly extends its life by removing the large debris that clogs them quickly.  By utilizing ACBs instead of pre-filter media in the Safety Canopies, ACBs eliminate their clogging.

Without the clogging, Air-Cleaning BlowersTM can assure bus, trolley and other designers of a constant and predictable airflow, air pressure and energy consumption.
