The Air Systems International CVF12A15KT and CVF12A25KT are premium, all-in-one confined space ventilation kits designed to provide maximum fresh air delivery without compromising worker access. Built around the powerful 12-inch CVF-12AC axial blower, these comprehensive systems feature the patented Saddle Vent® manhole ventilation device, allowing teams to continuous purge underground spaces while keeping the entry point completely clear and safe for entry and egress.
Available in either a 15-foot (CVF12A15KT) or 25-foot (CVF12A25KT) ducting configuration, these kits provide everything a contractor needs for immediate OSHA compliance in non-hazardous workspaces.

Key Features & Benefits
• Patented Saddle Vent® Technology: The game-changing component of this kit. The low-profile Saddle Vent® drops directly into the manhole opening, taking up only 3 inches of space. Workers can easily climb in and out of the space without having to remove or crush the ventilation hose.
• Massive 12-Inch Air Purging Power: Driven by a robust 1 HP electric motor operating on standard 115 VAC power, the system delivers an incredible 2,348 CFM of free air to rapidly clear out stagnant heat, fumes, and stale air.
• All-In-One Organized Portability: The kit features a snap-lock poly canister that secures directly to the fan housing. It keeps your flexible ducting, 90-degree elbow, and mounting brackets neatly stored and protected from job site damage during transit.
• Built for Extreme Field Conditions: The fan, canister, and Saddle Vent® are constructed from high-impact, safety-orange polyethylene plastic that will never dent, rust, or corrode.
• Integrated GFCI Safety: Safety is paramount in the field. The blower comes standard with a built-in GFCI (Ground Fault Circuit Interrupter) plug to ensure safe operation in wet, damp, or unpredictable outdoor environments.
