Tooltopia carries exhaust hose and accessories to help evacuate carbon monoxide from running cars in repair shops. Cold weather keeps service bay doors closed and a running car can produce enough carbon dioxide in a short amount of time to create a dangerous situation. Tooltopia carries easy to install aluminum door ports to help evacuate auto and truck emissions outside through exhaust hoses, including multiple diameter options and tailpipe adapters as well. Don’t take chances with carbon dioxide emissions; make sure that your shop can evacuate vehicle emissions quickly from enclosed areas.
