Stick them through the side of the duct so that the bulb is in the airstream.
The configuration or orientation of the duct doesn't matter, you will be discharging into a small volume of space. The pendant sprays forward, away from the body of the sprinkler into the duct.

Depending on the duct size FlexHead has a great product for inserting sprinklers in ductwork. Use standard pendant style sprinklers. Also be sure to ask what is the normal operating temperature of the airstream in the duct and if there is an upset condition temperature increase variance. Get the right temp sprinkler. If there is a fire in the booth you can bet on it migrating into the ductwork so assume it's all one flow event. Craig L.

Does the individual spray area include the pendent sprinklers in the ceiling of the paint booth and the sprinklers in the exhaust duct? Whit the requirement of extra hazard group two is there a way that Horizontal sidewall sprinkler can be used in exhaust stacks.
