Exhaust hoses are used to remove toxic carbon monoxide from indoor automotive repair facilities. There are five types of exhaust hoses, each with varying costs and benefits. The motorized hose is the most advanced, while the manual hose is the most cost-effective. The exhaust hose drop with balancer is the best for large garages.
An exhaust hose is a type of flexible hose used to extract vehicle exhaust from an indoor automotive repair facility. A method of removing car exhaust is necessary as the exhaust contains carbon monoxide which is highly toxic. Exhaust hoses are very easy to use and provide a safe method of removing exhaust gases.
The basic purpose of an exhaust hose is to create a dedicated method of redirecting exhaust gases from a running vehicle outside, where the vapors can be harmlessly vented. To be practical, the hose must be easy to connect and disconnect from the vehicle and be permanently attached to a vent point outside the building. Mechanics must be able to move the hose with little effort, and the connector at the end of the hose must be able to fit into the tailpipe for a wide range of vehicles. There are five different types of vehicle exhaust hose: exhaust pull, manual hose, motorized hose, slip-on suction rail, and hose drop with balancer. The costs and benefits of different types of hose vary based on installation costs and the size of the installation required.
Exhaust extraction hose systems have a powered exhaust system designed to draw exhaust from the tailpipe and push it out of the building. The hose system itself is connected to the interior ceiling of the garage. Multiple hose drops are installed at specific intervals to correspond with vehicle bays. The hose can be configured in different sizes, ranging from 3 inches (7.6 cm) to 8 inches (20.3 cm) in diameter.
A manual exhaust hose is a simple, insulated hose that runs from the exhaust pipe to a cutout in the garage door. The cutout is the same dimension as the hose and ensures that all exhaust exits the garage. This is the most cost effective method of running the exhaust hose outside of the garage. A rope and pulley method can be used to retract the hose when not in use, or it can be mounted on a reel for safety and storage reasons.
The motorized hose can run on a retraction reel and work with various hose sizes and high heat levels. The hose reel is made of steel components and is designed for use with a radio remote control. The motorized hose has a built-in mechanism designed to lower the hose to any position.
A slip-on suction rail exhaust system allows the user to install multiple exhaust hose drops, but reduces fan size and horsepower required by using a shared rail. This design provides improved energy efficiency, which saves electricity costs. However, this sliding suction rail system requires a tighter seal to maintain the same suction levels.
An exhaust hose drop with balancer is designed for a very large garage and provides all the functionality of a motorized exhaust hose system, but with load and air balancing. This feature ensures that exhaust is continuously pressurized to flow out of the building, regardless of the number of exhaust hoses attached. It is the best type of system for a large garage.
