Info & Guides

Description

Long duct runs and big spaces need a fan that keeps air volume up without wearing out early. The FKD 18 pairs the high airflow of an axial fan with the reliability of a backward-curved impeller.

The FKD 18 is rated for both commercial and residential use, so it fits an office ventilation upgrade as well as a large home exhaust project. Its terminal box and maintenance-free bearings keep setup and upkeep simple, so the fan can run for long stretches inside your ductwork without regular service.

Key Features and Benefits of the Fantech FKD 18 Mixed Flow Inline Duct Fan

  • Mixed Flow Design: A backward-curved impeller combined with axial-style airflow gives you high air volume with the durability of a centrifugal wheel.
  • Duct Connection: Fits 18-inch round ductwork, so you can install it directly into large commercial or residential duct runs.
  • Galvanized Steel Housing: Airtight galvanized steel housing keeps air moving through your ducts instead of leaking out at the fan.
  • Thermal Overload Protection: The external rotor motor has built-in thermal protection, which helps keep the motor from overheating.
  • Sealed Ball Bearings: Permanently lubricated sealed ball bearings mean you never have to oil or service the motor bearings.
  • Full Speed Control: With manual controls and 100 percent speed control, you can dial airflow down to match demand, and the motor still sheds heat well at low RPM.
  • Prewired Terminal Box: A terminal box with a prewired electrical strip makes the hardwired connection faster for you or your electrician.
  • 140-Degree Air Rating: Handles air stream temperatures up to 140 degrees F, so the fan can move warm exhaust air from kitchens and busy workspaces.
  • UL Certified: UL certification confirms the fan meets recognized electrical safety standards for your installation.
  • Space Requirements: Measures 21.75 x 17.625 x 24.5-Inches (L x W x H) or 27.25 x 17.625 x 28.5-Inches (L x W x H), so check clearance first.

Choose Your Voltage and Airflow Capacity

Pick the 120-volt model, a 230-460-volt model, or the higher-capacity XL based on your power supply and airflow needs.

  • Fantech FKD 18 120V: Runs on 120-volt power and moves up to 4,448 CFM at 24 sones, the quietest rating in the line, and weighs 132 pounds.
  • Fantech FKD 18 230-460V: Runs on higher-voltage service, moves up to 4,490 CFM at 25.9 sones, and weighs 127 pounds, which makes it the lightest model in the line.
  • Fantech FKD 18 XL 230-460V: Building on the higher-voltage model, it pushes airflow to 6,225 CFM, but its 32-sone rating means it runs noticeably louder and it weighs 149 pounds.

Sylvane's Expert Take

If you're ventilating a commercial kitchen or a large home through 18-inch ductwork, the FKD 18 line is a strong fit. Your power supply should settle most of the choice: the 120-volt model fits lower-voltage circuits, while the 230-460-volt models need higher-voltage power. Pick the XL only if you need the extra airflow and can live with its noise.

Every model weighs more than 125 pounds, so confirm your structural supports before installing. Manual speed control lets you dial airflow up or down as demand changes.
