Is 3,670 CFM enough for my room?Compare this fan

Specs cited from Manufacturer source ↗Photos: Amazon listing ↗ · refreshed Oct 31, 2026

The Air King 9420 is a 20-inch industrial pedestal fan with Air King's full spec table: 3,670 / 3,330 / 2,940 CFM, 184 W on high, and a comparatively quiet 62 dBA on high, dropping to 48 dBA on low.

What works

  • 3,670 CFM on high from a 20-inch head
  • 3 speeds, down to 2,940 CFM on low
  • Tilting head to aim the airflow
  • 1/6 HP motor on standard 120 V power
  • 9-ft power cord

What doesn't

  • No oscillation
  • Does not oscillate
  • At 64 inches tall and 34.3 lb, it is bulky for a 20-inch fan
  • Half the airflow of Air King's 30-inch pedestal

Who it's for

Good fit

  • Workstations, assembly lines and small shops that need steady, aimed air at body height
  • Occupied spaces where the 62 dBA high setting and 48 dBA low setting matter
  • Buyers who want documented CFM, watts and dBA at every speed

Look elsewhere if

  • Large open floors, where a 30-inch fan with twice the airflow does more
  • Anyone who wants oscillation; the 9420 has none

Why it stands out

The 9420 is the documented middle ground between a shop fan and a comfort fan. Air King's model table gives every number you need: 3,670 / 3,330 / 2,940 CFM, 184 / 155 / 130 W and 62 / 55 / 48 dBA across three speeds, from a 1/6 HP, 120 V motor at 1,500 RPM on high. Those sound figures make it one of the quieter industrial fans with published data. Its low setting, at 48 dBA, is gentle enough for staffed workstations.

On the hardware side, it has a pivoting pedestal head, a rear rotary control and a 9-foot cord. The listing adds a powder-coated steel build, a fully enclosed, permanently lubricated motor and a 1-year limited warranty.

What to know before you buy

  • Power: 1.6 A on high from any standard 120 V outlet. The 9-foot cord reaches most workstation spots.
  • Space: Air King lists 23.25 x 26.5 x 64 inches and 34.3 lb. Give the base a clear footprint away from walkways.
  • Noise: 62 dBA on high is moderate for an industrial fan. Use medium or low near desks and benches.
  • Coverage: it does not oscillate. Aim it at the work zone rather than expecting it to sweep a room.

How it compares

  • Air King 9020 wall mount: the same 3,670 CFM, 184 W and 62 dBA in a 26 lb wall-mount package. Choose it to free up floor space.
  • Air King 9130 pedestal: the 30-inch step up. Air King lists 7,400 CFM, but also 255 W and 75 dBA on high. Choose it for bigger, noisier spaces.
  • Tornado 20-inch oscillating pedestal: its listing claims 5,250 CFM, 120W, 80-degree oscillation, an IPX4 water-resistant rating and 66 dB. It gives more claimed air plus oscillation, but on listing claims rather than a manufacturer table.

Bottom line

The 9420 is a well-documented, comparatively quiet 20-inch pedestal fan for cooling people where they work. Buy it for workstations. Choose an oscillating or 30-inch model for whole-room airflow.

Verdict

Buy the 9420 if you want a documented, relatively quiet pedestal fan to cool people at workstations. Skip it if you need to sweep air across a room (it doesn't oscillate) or push air across a big floor, where the 30-inch Air King 9130 does more.

Before you buy

Installation and buying checks

Use these questions to verify the exact configuration. Linked facts are cited; unlisted details stay questions.

  1. Mounting and support

    Does the planned location suit the listed pedestal mounting, with the required support, clearance, and service access?

  2. Clearance and handling

    Do the listed physical details leave enough clearance for installation, adjustment, and service?

  3. Electrical match

    Does the documented electrical information match the planned supply? Confirm the installed unit’s nameplate and installation instructions before connecting it.

  4. Airflow at the job

    Is the listed airflow rated at an operating point that matches the job after placement, obstructions, and system resistance are considered?

  5. Location requirements

    Does the site require an environmental rating or guard? Neither is listed here.

Put 3,670 CFM in context

The Air King 9420 20-Inch Pedestal Fan has a listed airflow of 3,670 cubic feet per minute. The table compares this rated volume with example room volumes. It does not measure fresh-air exchange, air speed at your body, or room coverage.

RoomSizeNominal room volumes / hourNominal pass interval
One-car garage22 × 12 × 9 ft · 2,376 ft³93×39 s
Two-car garage22 × 20 × 9 ft · 3,960 ft³56×1.1 min
Workshop40 × 30 × 12 ft · 14,400 ft³15×3.9 min
Warehouse bay100 × 50 × 16 ft · 80,000 ft³2.8×22 min

A circulation fan does not by itself replace indoor air. Exhaust airflow depends on a makeup-air path and system resistance. Use installed outdoor airflow for ventilation calculations.

Formula: airflow × 60 ÷ room volume. CDC explains the ventilation form of this equation; here the input is a catalog rating, so the result is a volume comparison.

Operating estimate

What could it cost to run?

This uses the listed 184 W power draw. The example below assumes 8 hours a day, 250 days a year, at $0.16 per kWh. Change the assumptions for your utility rate and schedule.

$59estimated electricity cost per year

This is an energy estimate, not a bill. Draw can vary by speed, supply voltage, controls, and the fan's actual load.
