Abstract: An air scrubber for removing oils and contaminates from air has an underside inlet for the introduction of contaminated air. The contaminated air passes through a reduced aperture passageway which prevents retrograde flow of contaminates or cleaning fluids contained in the scrubber. The contaminated air is thereafter directed upwards through a scrub reservoir having a plurality of apertures, such that the contaminated air passing through the apertures forms jets which cause interaction between the cleaning fluid and the contaminates, thereby creating droplets containing cleaning fluid with entrapped contaminates, and cleaned air. The droplets and air are directed to a mist eliminator having a plurality of chevron V structures which capture the droplets and return them to the main reservoir. A circulating pump moves cleaning fluid from the main reservoir to an upper reservoir which spills into the cleaning reservoir.

Abstract: A scrubber has a return air inlet and an outside air inlet receiving contaminated air into a passageway with an aspect ratio greater than 4, the passageway surfaces wetted by a fluid disposed from a pre-wetter. The passageway has a first section whereby contaminated air travels downward toward the fluid surface of a main reservoir, and is thereafter directed upward and through a scrub reservoir having a plurality of apertures. The contaminated air mixes with the fluid of the scrub reservoir, forming a mixture of contaminants and fluid which are returned to the main reservoir, and also producing clean air with airborne fluid droplets which are passed to a demister pad for separating the fluid droplets and returning them to the reservoir, and the cleaned air is provided to a clean air outlet. A blower moves the air through the scrubber, and a pump pressurizes fluid from the main reservoir and provides it to the pre-wetter and to the scrub reservoir, such as through a gutter reservoir.
