SKU CH-ZKPK-A98R4 MPN 4YC87

Roof-mounted exhaust fan with a 12 in aluminium blade delivering 1,014 cfm at zero static pressure from a 1/6 hp 115V motor

  • TypeDrain Components
  • 12-inch blade moves 1,014 cfm exhaust airflow
  • 1/6 hp motor runs on 115V AC single-phase power
  • Aluminum housing withstands 120 °F inlet air temperature
  • Assembled downblast design mounts directly on roof
  • Four-blade axial configuration delivers 3/8 in wc static pressure

Roof-mounted exhaust fan

This axial downblast fan installs on a roof and arrives fully assembled. A 12-inch aluminum blade is driven by a 1/6 hp motor rated for 115V AC single-phase power. The unit moves 1,014 cfm of exhaust air at zero static pressure and handles inlet temperatures up to 120°F.

Suited for low-pressure roof ventilation

Builders needing a single-speed exhaust fan for general roof-mounted airflow will find the open air-over motor enclosure and 3/8 in wc maximum static pressure adequate. Installations that require high-static pressure capability, variable speed control or high-efficiency motor ratings should select a different model.

1,014 cfm at zero static pressure

This airflow figure defines the ventilation capacity when no duct resistance is present. The fan delivers the same 1,014 cfm for supply air under identical conditions, so specifiers can match the rating directly to the roof opening requirements.

Questions about this item

What airflow does the 115V AC motor deliver at zero static pressure?

The fan moves 1,014 cfm of exhaust or supply air when measured at 0.000 in wc static pressure.

Will the 29-inch long by 28.6-inch wide aluminum housing fit my roof curb?

The assembled unit measures 29 in long, 18.3 in high and 28.6 in wide, so verify your curb opening against those outside dimensions.

How is the single-speed motor wired during installation?

Connect the 115V AC single-phase supply directly to the open air-over motor leads; the common mistake is forgetting that no internal disconnect or speed control is provided.
