A 30 inch circulator is the wrong tool for cooling one person at one bench. The Airmaster 78974 (model I-18LS) is an 18 inch low stand pivot fan built for exactly that job: it sits on the floor at the operator's feet, pivots up at the torso, weighs 15 lb, and moves 2,966 CFM on high through an aluminum propeller behind an OSHA-compliant nickel chrome guard.
Built for
- Bench and machine-tool stations: machinists, assembly, inspection and small-parts finishing, where the airstream needs to land on the operator rather than the ceiling.
- Garage bays, small engine shops and tire shops, where one tech moves the fan a dozen times a day.
- Schools, kitchens, salons, mailrooms, kennels and tack rooms, where an industrial circulator is overkill and a household box fan will not pass a safety walk.
Why the low stand matters
The low stand plus pivot head gives a stable, tip-resistant base with no pedestal column to knock over, which is the practical difference from a consumer fan in a bay where carts and hoses move constantly. It also has a genuine three-speed switch rather than the "off, windy, very windy" arrangement on cheap shop fans: low is 2,013 CFM at 1,180 RPM, which is actually usable as all-day background airflow. The 10 ft cord is another quiet advantage, since most consumer fans ship with six feet and the difference is whether you run an extension cord across a walkway.
One honest note on environment: this fan uses an open drip-proof motor. That tolerates falling droplets but not dust ingress or washdown. For sawdust, grinding dust, ammonia or wet areas, step up to a totally enclosed motor.

Airmaster publishes no decibel rating and no pivot range in degrees for the low stand, and this model does not have casters, so none of those are claimed here.
Frequently asked questions
Is this the 4,550 CFM version?
No. This model is 2,966 CFM on high. The 4,550 CFM 18 inch low stand is a different part number with a totally enclosed high-velocity motor. Some sellers publish 4,550 CFM against this number, which is incorrect.
Can I use it in a dusty or damp area?
Use caution. The motor is open drip-proof, not totally enclosed. For woodshops, wash bays, barns or grinding areas, choose a totally enclosed model instead.
Can I bolt it to a bench or a post?
Not this one, which is the floor low stand version. Airmaster makes a work station yoke mount with the same 1/8 HP performance that fastens to a surface with a single bolt or lag screw.
Will it be quiet enough to talk over?
On high at 1,600 RPM, not really. Run it on medium or low at a manned station. Airmaster publishes no decibel figure for this fan.
How many can I run on one circuit?
At 1.65 amps on 115 V, four or five will share a 15 amp circuit comfortably.
Discount Cleaning Products carries the Airmaster workstation and heavy-duty fan lines together, so a bench fan and a bay circulator can come from one order. Our US-based team can help you match motor type to the environment before you buy.
