AI-generated imageA Dayton shutter mount exhaust fan is a wall-mounted, direct-drive centrifugal or propeller fan with automatic gravity shutters on the intake side that open when the fan runs and close by gravity when it's off, blocking backdraft and outside weather intrusion. The fan mounts into a square wall opening with a flanged frame carrying eight pre-punched slotted mounting holes, and a wire intake guard on the exterior meets OSHA's 1/2" maximum opening requirement for finger and debris protection.
Facilities managers, farm and greenhouse operators, and general contractors rely on Dayton shutter mount fans for stores, offices, factories, shops, farm buildings, and greenhouses wherever simple, reliable wall-mounted exhaust ventilation is needed without ducting. Their charcoal metallic corrosion-resistant finish, fully assembled shipping, and broad size range spanning compact 10" units to heavy-duty 36" fans give facilities a straightforward way to match fan capacity to room size, from small offices needing a few hundred CFM up to large industrial spaces needing well over 8,000 CFM. That finish handles ordinary damp and dusty air, but for wash-down bays, coastal sites, or chemical rooms a purpose-built corrosion resistant shutter mount fan is the better starting point.
Common configuration: blade diameters from 10" to 36", single-speed or variable-speed motor options, 115VAC standard voltage (larger or heavy-duty models may use 230V or three-phase), single-phase, 60 Hz operation, motor RPM ranging from roughly 825 RPM on large low-speed units up to 1,725 RPM on smaller high-speed units, and CFM ratings published at multiple static pressure points (0.000", 0.125", 0.250" in. SP) to reflect real-world ducted or resistance-loaded performance.
Stop second-guessing. Match your use case below — then let ChatMRO's AI surface the exact model, CFM data, and alternatives in one natural-language search.
Small offices, utility closets, or spaces where low noise matters. 10"-12" fans dominate here.
Standard workshop, garage, and mid-size commercial ventilation needs. 18"-20" fans dominate here.
Large open industrial spaces, barns, and agricultural buildings needing maximum airflow.

| Model/Size | CFM @ 0.000" SP | Motor HP | Best For | Sones | Square Opening | ChatMRO Verdict |
|---|---|---|---|---|---|---|
| 10" Variable Speed | 600-625 | 1/15 HP | Small rooms, quiet office ventilation | 6.19 | ~13-1/8" | Best for the quietest, smallest-footprint installations |
| 12" Variable Speed | 775 | 1/15 HP | Small-medium rooms needing adjustable airflow | 5.9 | 13" | Good when variable speed control matters more than max CFM |
| 18" Standard | 1785 | Model-specific | Mid-size workshops, small commercial spaces | Model-specific | ~19-21" | Solid middle ground between compact and full workshop-size fans |
| 20" (1/4 HP) | 3948 | 1/4 HP | Standard workshops, garages, farm buildings | 7.01 | 21" | Most common choice for general workshop/garage ventilation |
| 20" (1/3 HP) | 4700 | 1/3 HP | Slightly higher airflow needs at the same footprint | 8.1 | 21" | Use when 1/4 HP CFM isn't quite sufficient for the space |
| 36" Heavy-Duty | 8225-8860 | 1/2 HP | Warehouses, barns, large industrial spaces | 8.24 | 37" | Best for the largest open spaces needing maximum airflow |

Whether you're a facilities manager ventilating a new workshop, or a farm operator replacing a worn-out barn fan — use this framework before you procure.
As a general guide, small areas may only need 700-1,000 CFM, while large industrial spaces may require 10,000+ CFM — when unsure, choose a slightly higher CFM rating for better ventilation margin.
Published CFM at 0.000" in. SP represents free-air, no-resistance performance — if your installation has any ducting or resistance, check the CFM figures at 0.125" and 0.250" SP for a more realistic expectation.
Each fan model specifies a required square opening (e.g., 21" for a 20" blade fan) — verify your existing or planned wall opening matches before ordering to avoid costly rework.
Smaller fans average around 6 sones (similar to a range hood) while larger units run louder — factor in whether the space is occupied by people sensitive to fan noise.
Most small and medium Dayton fans run on 115V, while larger or heavy-duty fans may require 230V or three-phase power — confirm your electrical service before ordering. The same voltage check applies when a fan is rebuilt rather than replaced, since 115V open drip proof replacement motors are specified separately from the fan assembly.
Motor HP and RPM affect delivered CFM even at the same blade diameter. Search by function on ChatMRO — the AI surfaces exact matches AND available substitutes sized to your actual airflow need.
If any ductwork or resistance is present downstream of the fan, relying on the 0.000" SP CFM rating will overestimate real-world performance — check the 0.125" or 0.250" SP figures instead.
Each fan size requires a specific square wall opening slightly larger than the blade diameter — confirm this dimension matches your installation before purchase to avoid needing to modify the wall opening.
