SWEET-VENT FILTER units are designed to provide the same adsorption functionality as larger units, only on a smaller scale. Each vent unit can be custom-fitted to meet the contaminant removal requirements of almost any application. The SWEET-VENT filter can be filled with media custom-selected to provide the maximum time on stream between changeouts and to deliver the optimum contaminant removal while in service. Small PVC canisters containing a variety of media for flows up to 50 acfm.

Small cartridge scrubber complete with corrosion-resistant fan and motor assembly. Unit is housed in a vented fiberglass enclosure. Sized to handle lateral line and individual residential/commercial structure odor control. Sweet-Aire Cartridge scrubber units are designed to provide the same adsorption functionality as larger units; but only on a smaller scale. Each unit can be custom-fitted to meet the contaminant removal requirements of almost any application. The carbon cartridge can be filled with media custom-selected to provide the maximum time on stream between changeouts and to deliver the optimum contaminant removal while in service.

A series of very durable, passive odor control units fabricated from 304SS for extended system life designed to be suspended in the manhole opening.

The SWEET-AIRE DEEP BED OCS systems, incorporating granular activated carbon, and other media, deliver the lowest life-cycle cost and the highest hydrogen sulfide (H2S) removal efficiency, of any process on the market. Each system will provide consistently high H2S removal efficiency (>99%) regardless of the fluctuation in the inlet H2S concentration – without any operator adjustments to the system. The systems can be supplied with a wide variety of adsorbent media or blends of media to provide complete odor removal of any mixture of malodorous compounds.

Fiberglass units with single or dual-beds of activated carbon media in standard sizes ranging from 4 feet to 12 feet in diameter. Airflow capacity up to 14,000 acfm per unit.

Sweet-Air PE-200 HDPE drum scrubber units are designed to provide the same adsorption functionality as larger units; but only on a smaller scale. The drums can be filled with media custom-selected to provide the maximum time on stream between changeouts and to deliver the optimum contaminant removal while in service.

Sweet-Aire PE-300 MDPE drum scrubber units are designed to provide the same adsorption functionality as larger units; but only on a smaller scale. The drums can be filled with media custom-selected to provide the maximum time on stream between change outs and to deliver the optimum contaminant removal while in service.

SWEET-AIRE PE-500 MDPE drum scrubber units are designed to provide the same adsorption functionality as larger units; but only on a smaller scale. The drums can be filled with media custom-selected to provide the maximum time on stream between changeouts and to deliver the optimum contaminant removal while in service.

Units designed to protect downstream process equipment and media from contamination or plugging from airborne fats, oils, greases (FOG), particulates, and entrained water droplets. Units are available in fiberglass, stainless steel, or coated mild steel.

A selection of corrosion-resistant fans fabricated from various materials of construction and offered in either direct-drive or belt-driven configuration.
