Dryer Taking Too Long or Overheating? Booster Fan PWS100 – Fix Long Duct Run Performance Fast

Long dryer duct runs are the #1 cause of extended drying cycles, overheating, and lint buildup in Canadian homes — and most dryers aren’t built to handle them. Most residential dryers are engineered to exhaust through no more than 15 feet of duct with two elbows. When your installation exceeds that, airflow drops, drying times climb, and lint accumulates in the duct — creating a fire hazard and driving up energy costs. ⚡ Common performance issue in homes with basement laundry rooms, long exterior duct runs, or multiple elbows. The Reversomatic PWS100 is a purpose-built inline dryer booster fan with a paddle-wheel impeller specifically designed to resist lint buildup — restoring full airflow and cutting drying times back to normal.

❓ Is This the Right Solution?

This is the correct fix if ALL of the following are true:

• ✔ Your dryer runs normally but clothes take 2+ cycles to dry fully
• ✔ Your duct run exceeds 15 feet or includes more than two 90° elbows
• ✔ Your dryer heating element and thermostat have been confirmed OK
• ✔ The only problem is insufficient airflow through a long or complex duct run

🔧 Common Symptoms of Restricted Dryer Airflow

• Clothes still damp after a full drying cycle
• Dryer runs hot but airflow at the exterior vent is weak
• Lint accumulating inside the duct or around the dryer
• Drying times have increased gradually over months
• Dryer trips thermal cutoff or overheats and shuts off mid-cycle
• Musty smell from laundry after drying

✔ If these symptoms match, a duct booster fan is the most effective solution for long-run installations.

✔ In most cases, installing the PWS100 restores normal drying times and eliminates overheating immediately.

⚙️ Installation

Skill Level: MODERATE — 60–90 minutes. Disconnect the dryer from power before beginning. The PWS100 installs inline in the dryer exhaust duct, typically in an accessible section of the run (basement ceiling or wall cavity). Use the included transition fitting to connect to your existing duct. The unit requires a standard 120V outlet nearby for power. Secure all duct connections with foil tape (not screws, which catch lint). Restore power and run a test cycle to confirm improved airflow at the exterior vent. Consult a licensed HVAC technician if duct access is limited or the run passes through finished walls.
