Companion flanges install between ductwork and inline fans. They serve as a union or adapter between the ducting and the tubeaxial fan. They are sold in pairs to allow for inline installations and feature pre-drilled mounting holes to match the fan mounting pattern.

Curb caps adapt a roof curb to accept a tubeaxial fan and convert it into an upblast ventilator fan. They are constructed of heavy gauge steel and have a UV-resistant enamel coating to resist the elements.

Discharge caps install onto the exhaust fan on the exterior of a building. They feature free-floating louvers that act as a one-way valve to reduce backdrafts into the structure.

Fan guards mount to either the intake or exhaust of a tubeaxial fan and protect users from injuring themselves on the spinning blades.

Fan vents install into ceilings and provide a termination point for ductwork connected to an inline fan. Some units feature integrated lights while others serve as the vent into the occupied space.

Duct boots install between heater inline duct fans and the existing ductwork. They are made from rubberized canvas and provide a flexible, noise-reducing joint.

These thermostats provide a wireless method of controlling a heater inline duct fan.

These motors replace nonfunctioning motors in tubeaxial fans, which provide ventilation to paint spray booths and similar industrial areas where they install into existing ductwork. Motors should be matched to a tubeaxial fan with a compatible part number.
