AF500 Portable HEPA Air Scrubber

The AF500 AIR-SCRUB-R™ from General Equipment Company is a portable HEPA air filter. This air scrubber is suitable for establishing a healthier environment in commercial and industrial applications involving activities such as floor cleaning, grinding and polishing, and drywall installation and repair. This highly compact and efficient solution provides air scrubbing/negative pressure air movement capabilities on virtually any non-hazardous job site.

An air scrubber is a portable filtration system that seizes airborne particles and improves the air quality. The AF500 features a two-stage design, with a 30% pre-filter and a 99.7% efficient HEPA secondary filter, requiring fewer filters to be inventoried over competitive models. Able to capture particles down to 0.3 microns, the unit can remove particulates such as airborne allergens, soot particles, and mold spores stirred up by air movement during any type of project. Also, when the standard pre-filter is replaced with an optional carbon/potassium permanganate filter, the air scrubber absorbs a wide range of VOCs, smoke, and other noxious contaminants and odors.

Built with a ¼-horsepower, 115 VAC variable speed electric motor and a large 16″ diameter inlet for improved airflow and maximum filter surface area exposure, the AF500 offers adjustable airflow rates up to 500 CFM. In addition, the larger inlet provides low power consumption, requiring only 1.9 amps compared with 8″ inlet models. The air scrubber is designed to be stackable and weighs only 33 pounds, making it more compact and up to 10 pounds lighter than most competitive units. This provides for easier positioning about the jobsite.

The UL certified air scrubber uses an integral GFCI outlet with 12-amp breaker, allowing up to four units to be daisy-chained together while connected to one outlet. Standard lay-flat ventilation ducts connect to the 10″ outlet for negative/evacuation airflow applications.

For maximum durability, the AF500 housing is constructed of high-density, UV-resistant polyethylene. This helps contribute to its quiet 56 dBA to 72 dBA operational sound levels, which is equivalent to a standard air conditioner. A clean filter indicator light tells the operator when the filter needs changing to maintain optimum airflow and maximize performance.
