Inline duct fans are typically used to bolster airflow through ducting in buildings and homes. If you own or operate a duct fan, you may find yourself in need of various accessories to improve performance or to replace a broken or worn-out part. Accessories such as exhaust grilles, industrial dampers, inline backdraft shutters, noise silencers and clamps can all be used to aid and abet the performance of your duct fan. Items like these are especially prized by those maintaining HVAC systems or working in maintenance, where accessories wear out more often than you'd expect.
