Alert’s Vent-A-Garage, No. VG200, is a two-bay ventilation system that exchanges inside fumes with fresh air. Two 22-watt quiet exhaust fans draw bad air out at 230 cfm and two bottom vents allow fresh air in. Bottom vents include a snap cover to seal during inclement weather. Installation is easy because of modular plug-in wiring; built-in circuit breaker increases safety. Single bays use No. VG100.
