The Air Systems International line is an all-in-one, contractor-grade portable ventilation system engineered to deliver high-volume fresh air to confined work zones. This convenient package pairs the powerful 12-inch axial fan blower directly with a rugged, snap-lock poly canister housing of flexible ducting. Operating on standard 115 VAC power, this system provides massive air-purging capabilities while keeping your safety gear organized, protected, and incredibly easy to transport.

The Air Systems International CVF-12AC is a high-performance, contractor-grade 12-inch portable axial ventilation fan engineered to deliver rapid, high-volume airflow to confined workspaces. Operating on a standard 115 VAC power supply, this rugged yet lightweight blower provides up to 2,348 CFM of free-air movement, making it the ideal choice for utility manholes, construction sites, and manufacturing facilities requiring reliable, non-hazardous ventilation.

The Air Systems International 8-Inch Axial Blower Kit Family provides the ultimate, ready-to-deploy confined space ventilation system for utility workers, safety teams, and contractors. Headlined by the industry-standard CVF8A15KIT (115V AC) and backed by the remote-ready DC battery-powered family, these comprehensive packages combine a high-velocity 8" axial fan, a protective storage canister with flexible ducting, and the patented Saddle Vent® manhole ventilation device.

The Air Systems International 8-Inch Axial Canister Fan Family delivers an all-in-one, highly portable ventilation solution designed to clear confined workspaces rapidly. Headlined by the standard CVF-15ACAN (115V AC), this contractor-grade family includes the specialized DCAN (12V DC) series.

The Air Systems International CVF-8AC is a highly reliable, contractor-grade 8-inch portable axial ventilation fan engineered to deliver rapid, dependable airflow to confined workspaces. Operating on a standard 115 VAC power supply, this compact, lightweight blower provides up to 974 CFM of free-air movement. It is the industry-standard choice for utility manholes, telecommunications vaults, and light construction sites requiring efficient, non-hazardous space ventilation.

The Air Systems SVB-A8 is a high-performance, 8-inch pneumatic centrifugal blower engineered for environments where electricity is unavailable or unsafe. Powered by a rugged 4 HP air motor, this intrinsically safe unit delivers massive airflow up to 3,000 CFM depending on air supply pressure, making it the ultimate tool for demanding industrial air purging.

• Designed for confined spaces and hazardous areas.

The Saddle Vent takes up only 3 inches in a manhole and functions as an air conduit. An eight inch air hose is attached to both ends of the Saddle Vent and placed in the entry access hole, thus eliminating the need to remove the hose each time entry or egress is required. The saddle Vent’s unique air flow design does not reduce air flow to the worker.

The Air Systems International 8-Inch Steel Axial Blower Canister Fan Family provides a heavy-duty, maximum-durability ventilation solution for demanding industrial jobsites. Unlike standard plastic-bodied models, the headlining SVF-15ACAN series features a rugged, powder-coated steel housing engineered to withstand structural impacts in tough work areas.

durable polyethylene duct-to-duct connector, allowing technicians to securely link multiple 8-inch hoses (such as the SVH-25) together for extended ventilation runs in non-hazardous locations.

The Air Systems International 8-Inch Axial Blower Duct Canister Family provides a rugged, stream-lined solution for storing, protecting, and deploying flexible ventilation hoses in the field. Engineered to snap directly onto the CVF-8AC and CVF-8EXP series 8" axial fans, these heavy-duty poly canisters shield your ducting from tears, punctures, and crushed folds during transport and storage.
